Reduce amount of water consumption from conventional recirculating water systems such as cooling towers, hydronic HVAC systems, or process water systems by decreasing the need for make-up water caused by evaporation and system blowdown (or bleed). Requirements: Provide an integral chemical-free water treatment technology in place of conventional water treatment which uses potentially toxic chemicals which may also produce potentially hazardous chemical byproducts. Provide documentation in the form of a letter from the project engineer that includes a narrative description of the chemical-free water treatment system used and how the system works. The narrative shall specifically state the environmental benefits of using the chemical-free process in place of the conventional chemical water treatment system; state specific chemicals and their estimated quantities eliminated by substituting the chemical-free process; state the methods and quantities of process water discharge as an estimate of potential water savings. Rationale: Recirculating water systems used in building mechanical processes such as HVAC heat rejection in cooling towers and hydronic heating and cooling systems often use chemical infiltration using manual or automatic injection processes in order to chemically treat the water contained in them. Chemical treatment is typically used for a wide range of functions such as the prevention of mineral scale formation, control of microbiological populations, and to inhibit corrosion. These functions may be equally served by the introduction of an electronic process known as pulsed power technology. Environmental benefits of the pulsed power technology are achieved simply with the elimination of potentially hazardous chemicals and their toxic byproducts used to prevent formation of mineral scale, control of microbiological populations, and inhibit corrosion. Conventional chemical treatment systems often ultimately cause the release of potentially hazardous substances into the environment through water discharge such as evaporation, spills, spray, and drift. In conventional process water systems such as open cooling towers chlorine or other biocides are used to control biological activity which is rapidly discharged to the atmosphere as chlorine gas. Corrosion inhibitors such as zinc, molybdenates, and phosphates are discharged in the drift from the cooling tower and spray settling to the ground as well as through the sewer system through blowdown draining. Water softeners, not needed in pulsed power processes, are typically used to prevent scaling and discharge quantities of salt brine as part of the softener process. The use of an alternative means of process water treatment in HVAC equipment such as the pulsed power technology is estimated to yield the following benefits and savings when applied to our building project: - the elimination of potentially hazardous chemicals and their toxic byproducts with the elimination of conventional chemical water treatment processes - saves the use of approximately 186 gallons per year of industrial strength chlorine bleach, 5 to 6 gallons of isothiazine, and 115,000 gallons of water containing 2 ppm zinc and 20 ppm phosphate from being discharged into the environment - saves the requirement for approximately 90 lbs. of chlorine per year (most of which is evaporated to the atmosphere) - Annual water usage savings of approximately 67,275 gal/yr when compared to a typical open system water cooling process (cooling tower) of the same capacity with conventional chemical treatment processes Please confirm attainability of this credit."

The project is a 13 level healthcare facility located in an urban setting in the northeastern United States. The hospital is sited in a mixed-use community complete with institutional and commercial facilities, as well as residential. The sought innovation in design is for the relocation of six residential structures on the project site that were completely reused and re-sited to areas of the neighborhood that were missing buildings. Through the creation of the project, the homes were completely recycled, and an urban neighborhood was renewed and strengthened. Design Approach: The neighborhood rebuilding innovation in design credit brings together several aspects of the project\'s sustainable design goals. The first is urban redevelopment. The project is an expansion of an existing urban healthcare facility. The hospital will utilize amenities and infrastructure available to the existing facilities rather than build on Greenfield site at the urban fringe. The hospital is committed to making a positive impact on the neighborhood it serves, and rebuilding the neighborhood is aligned with this strategy. The site is conveniently located within a few hundred feet of train, bus and shuttle lines thus reducing the need for automobile traffic and associated pollution and augmenting a pedestrian friendly area. It is a hospital goal to maintain high-density development without adversely impacting the surrounding neighborhood. The six houses occupied two back-to-back city blocks across the street from the existing hospital. All six houses are listed on the National Register of Historic Places. Over time the two blocks where the homes were located deteriorated. Two of the relocated houses had been separated from the rest of the residential part of this neighborhood by three vacant lots and a surface parking lot. The two homes are now located in a completely residential part of the neighborhood. One of the houses was an infill of a vacant, run down lot and provided a needed facelift to the South side of this street. The other house was relocated to a short block that had two houses on each side of a vacant lot, strengthening the residential presence on this street. The remaining four houses replaced the surface parking lot filling on the block to make it entirely residential, rejuvenating the area. All of the houses were moved and interspersed with five vacant lots. Specific environmental advantages not otherwise recognized by LEED and exceeding measurement thresholds set forth by LEED: Relocating the houses helped mitigate the negative impacts vacant lots can create such as the dumping of trash, vandalism, squatting, loitering, etc. The relocation effort of the six houses has a net positive impact on the construction waste management calculations. The homes will be included in the calculations for Materials and Resources credits 2.1 and 2.2: Construction Waste Management. The goal of the project is to exceed the 75% total of recycling/salvaging construction waste for the project by 15% so that in total 90% of construction waste will be recycled or salvaged. The total cost relocating the six houses was approximately 2.5 million dollars. Proposed submittals to demonstrate compliance: (1) Construction waste calculations will be provided. (2) The six historic residential structures were moved in a manner consistent with Moving Historic Buildings by John Obed Curtis (US Department of the Interior, 1979) and were properly documented for the rehabilitation/reconstruction of historic features prior to moving the buildings. (3) Before and after maps will be provided with the submission." "The combination of urban redevelopment efforts, a 90% diversion rate for the project and the multiple house relocation is consistent with the quantifiable additional benefits necessary to earn an Innovation credit.

The air-to-air energy recovery units deliver 1,648 cubic feet per minute (cfm) of outdoor air at constant volume or 38 cfm for each building occupant. This ventilation rate is almost twice the rate required by ASHRAE Standard 62. In addition, the air-to-air energy recovery units allow moisture transfer between the exhaust and outdoor air streams, helping to meet ASHRAE Standard 55 for comfort all year long. The total cost of the HVAC system is just $99,120 or $8.30 per square foot which includes all overhead and profit. This cost is 35% less than the lowest figure published by R.S. Means.

The procedure is based on a combination of: scrubbing the air with activated charcoal (AC) filters to reduce the number of critical rooms in a building that will require CO2 sensors; using air-to-air heat recovery for the building air: using time-of--day control of ventilation for the building zones. The proposed design procedure will enable selecting the minimum number of CO2 sensors to control the amount of delivered outside air. This will reduce the initial cost as well as the annual cost of maintaining their calibration. The new Pacific Garden Mission building in Chicago will house an average of 800 homeless people on any given night. The design calls for using activated carbon filters in the main air handling unit for the entire building to help control the peculiarly strong body odors of the guests and to reduce the required outside air and associated energy use. Three ""hot boxes"" will also be used to disinfect by 180oF+ heat all the clothes of the incoming guests as part of the thorough laundry process. The activated carbon filters are capable of reducing these outdoor air rates by over 70%. This was determined by applying the Indoor Air Quality procedure described in Section 6.2 of ASHRAE Standard 62-1999 Ventilation for Acceptable Indoor Air Quality1 To be conservative, we will assume that only a 50% reduction in outside air will be feasible because additional outdoor air may be necessary to control body odors by dilution. Besides reducing the cost of conditioning the ventilation air an additional benefit of the activated carbon filters will be to help reduce the number of CO2 sensors needed in the building for effective and affordable demand control ventilation. By reducing the required outside air by 50% the number of ""critical rooms"" is reduced. We define ""critical rooms"" as the rooms having a required minimum fraction of outside air, say 0.50, as calculated using the Ventilation Rate Procedure for multiple spaces and the Indoor Air Quality Procedure in ASHRAE 62,2-20012. The rationale for not installing CO2 sensors in rooms with outdoor air fractions below a specific number, say 0.50, is: 1. if regularly occupied rooms with outdoor air fractions above 0.50 are getting sufficient outside air, the rooms with lower fractions should automatically get sufficient outside air. 2. one air handling unit serves the entire PGM building. Therefore, a small number of CO2 sensors can control the outdoor air fraction throughout the building. (The air handler is equipped with multiple fans--their redundancy makes it acceptable to serve a building this size, approx. 118,580sf net interior floor area with one air handler.) 3. The design will also include air-to-air heat recovery at the main air handling unit using either run-around-coils or heat pipes. 4. For major parts of the day CO2 sensor control of the supply and outside air quantities for particular space will be overridden by direct time-of-day control by the central EMS. The building program is arranged so that during the daytime the lower two floors will be occupied and conditioned for occupancy. The upper two floors are dormitories that will be unoccupied and their environment will be kept at unoccupied settings, including just enough supply air to slightly pressurize these floors relative to the outside. Conversely during the evening hours, the lower two floors will be unoccupied and their environment will be kept at unoccupied settings with the minimal required supply air to temper the space and control building pressurization. The central EMS will be used to control the supply air to these large blocks of the building. (This will also allow using a very low diversity factor to size the main air handling unit since it will be used to condition about 1/2 of the building at any one time.) 5. The limiting factor in determining the minimum acceptable amount of outside air may very well be the perception of odors by the occupants. This may require higher amounts of outside for dilution of odors than what would be called for by the CO2 sensor. This will be determined empirically after occupancy begins. In summary, the above design features and program requirements make it possible to reduce the number of CO2 sensors at this job by at least 50%. This will be documented in the summary table of the Ventilation Rate Procedure analysis. As such, the use of activated carbon filters makes demand controlled ventilation economically viable. Our first question is whether the above package of design features and approach is acceptable for reducing the number of required CO2 sensors and the cost of DCV and whether this would be considered an Innovation in Design and suitable for receiving a a LEED credit. Our second question is whether we can calculate the energy savings due to the activated carbon filters using the same analysis method approved for demand control ventilation. The % reduction due to the DCV would be calculated by subtracting saved energy from DCV in the numerator and using the Base Case energy cost without DCV in the denominator. Our preliminary energy modeling indicates annual savings of at least $10,000 per year or about 5% of the projected energy costs of the Current Design. These savings would be included under EA Credit 1 Optimize Energy Performance. We look forward to the USGBC\'s comments on this potential innovation in design and on the savings calculation method for the activated carbon filters. 1. ASHRAE 62.2-1999 Section 6.2 and Appendix E 2. ASHRAE 62.2-1999 Section 6.1.3.1 Ventilation Procedure for Multiple Spaces" "Based on the description provided, it does not appear that there are additional environmental benefits from this design approach that would qualify for an Innovation in Design credit, for the following reasons. LEED requires compliance with the Standard 62 using the Ventilation Rate Procedure (VRP). Reducing outdoor air rates is only allowed using the Standard\'s Indoor Air Quality Procedure. To comply with EQp1, outdoor air rates cannot be lower than those prescribed by the VRP, whether charcoal filters are used or not. Unfortunately the VRP tables do not have a category for ""homeless centers."" If they did, the rates would be quite high given the source strength. The closest occupancy in terms of body odor source strength is a ""health club/weight room"" which requires 20 cfm/p plus 0.06 cfm/ft2. In any case, the designers may have to request help from ASHRAE SSPC 62.1. Based on EQp1, the ASHRAE 62 Indoor Air Quality Procedure cannot be used to reduce ventilation rates. CO2 sensors should be used to monitor air quality; an alternative method for monitoring air quality has not been substituted outside of manual control in response to odors. EQc1 requires CO2 monitoring in densely occupied areas for air handlers serving multiple spaces with varying occupancy. As long as your design meets this requirement, then it will qualify for a point under EQc1. CO2 DCV must be customized to this application since the project requires a much higher ventilation rate compared to the activity level. The standard assumptions used in determining CO2 setpoints assume CO2 concentration tracks bio-effluent concentration and that bioeffluent/CO2 emission rate tracks activity level. This works for typical projects, but it would not be true for a homeless center. The project team may want to reconsider application of CO2/DCV for this project. Under EAc1, the ASHRAE 90.1 methodology calls for the same outdoor air rate for both the budget and proposed building. If DCV is used on this project, the energy savings can be demonstrated through the ""exceptional calculation method"" allowed by the standard. The energy cost savings would be included in EAc1. Strategies such as CO2 and humidity monitoring are addressed under existing credits within the LEED Rating System. Please note that another issue unrelated to Standard 62 is disease control. Homeless people are often carriers of disease (e.g. TB) and can be highly susceptible due to health conditions. In this case, the recirculation of any air in a homeless center may not be desirable. While very good particle filters (e.g. MERV 15) can remove most bacteria and droplet nuclei carrying viruses. 100% outdoor air with heat recovery may be a better solution. Applicable Internationally.

So we estimated the effect of thermal mass by increasing the R-value of the masonry components of the walls by 20 to 30% according to industry guidelines.1 The resulting energy savings was about 5% of the total annual heating, ventilation and cooling costs for the two buildings. Using autoclaved aerated concrete results in additional thermal resistance due to the myriad air cells the cured concrete. (We used the same wall system in the Base Case energy model as per the ASHRAE 90.1 guideline for energy modeling-- the energy savings due to masonry construction is ""buried"" in the prescribed energy savings analysis.) Masonry walls provide superior acoustical isolation that can be further enhanced by filling the CMU cavities with grout or with a poured or foamed thermal insulation. 2. Minimize the use and cost of construction materials. a. Eliminate drywall & acoustical tile. At IMI drywall use was reduced by 97% to lower construction waste, lower project material costs due to fewer wall material components; lower installation costs due to the elimination of cutting, taping, plastering, and sanding steps; lower housekeeping costs, lower Operations and Maintenance (O&M) and life-cycle costs; and reduced likelihood of moisture and/or mold accumulation resulting in higher indoor air quality. This approach eliminates the waste and environmental disturbance caused by the manufacturing of drywall. Not using acoustical tile or any type of ceiling finish also reduces project costs and construction waste. It avoids the cost of maintaining the ceiling finish and improves access to the building infrastructure located at the ceilings; b. Avoid wood and wood-based materials to avoid harvesting old growth forests. Avoid wood-based products and their associated manufacturing processes and binders/adhesives that can adversely affect the indoor and public environment. The IMI project virtually eliminated wood by using steel, stone or concrete lintels and frames. Optimal Masonry Construction makes it more affordable to use small amounts of FSC-certified wood products or drywall with a very high recycled material content.; c. Use high recycled content masonry units (CMUs) that have at least 40% post-industrial recycled content; d. Avoid floor coverings. Over 95% of the floor area will be either durable concrete or terrazzo masonry floors sealed and protected by low or non-VOC coatings. The remainder is synthetic rubber flooring and a small amount of carpeting. For the new IMI National Training Center-the exposed masonry approach avoided an estimated $ 825,000 in construction costs due to eliminating entire building systems. 3. Minimize construction waste. Optimize the masonry system by coordinating the dimensions of the building, the thickness of the wall insulation and the rain screen air gap to minimize/eliminate the number of masonry cuts. This reduces masonry construction waste, construction costs and housekeeping costs. At the new IMI National Training Center this was done by half-overlapping the 8-inch face brick and selecting wall lengths so that there is no need to cut any of the bricks at the exterior corners. 4. Reduce Building Operation & Maintenance costs. This is done by: a. Improved moisture control. The 8-inch brick size and 1/2 overlap pattern used at the new IMI facility leave a four inch space between the outside of the concrete masonry unit (CMU) walls and the inside surface of the face brick. It makes it convenient and affordable to provide a 2-inch wide air gap for good moisture control-considered good practice in the industry.2,3 As described in Part 2a above, eliminating drywall and acoustical tile layers eliminates potential areas for moisture and mold build-up; b. Improved thermal insulation. The 4-inch space also allows for at least a 2-inch layer of continuous rigid board insulation over the CMU wall that greatly enhances the thermal properties of the walls. This is in addition to the added thermal insulation resulting from the high density of masonry walls; c. Decreased maintenance of exterior and interior finishes. As described in Part 2a above, the all-masonry construction and ""naked architecture"" design approach will reduce the cost of cleaning the building and the cost of periodic refurbishing interior surfaces and finishes. The materials require minimum maintenance except for tuckpointing that is done over 10 year or longer periods. The exposed building systems are easier to access and maintain. 5. Increased building safety, durability and longevity. All--masonry construction ensures the use of materials with high durability and damage resistance that also provide enhanced protection to occupants. Exterior and partition walls of masonry and stone, whether in the form of block, bricks, or poured concrete, are more resistant to damage from natural catastrophes and afford greater protection to the occupants than do drywall and wood products. Masonry and stone walls also afford greater protection to occupants from wind-borne projectiles under tornadic conditions as well as greater fire protection than typical drywall/framed wall systems. Masonry and stone construction make for a durable and long-lasting building. The proposed Innovation Credit would require satisfying at least six of the following design elements: 1) Drywall and acoustical tile cover less than 10% of all interior walls and ceilings 2) Use masonry construction for at least 90% of the structural and partition walls 3) Avoid using wood or wood-based products in the building or furnishings 4) Use aerated concrete for at least 5% of the total wall mass 5) Use a face brick pattern that eliminates avoid brick cuttings at exterior wall corners, 6) Provide at least a 2-inch rain shield space in the exterior walls 7) In climates covering areas such as Bowie, Maryland and further north, install at least 1-inch or continuous rigid insulation outside of at least 66% of the exterior walls mass 8) Use floor coverings are on less than 10% of the conditioned floor area 9) Expose at least 80% of all electrical and HVAC distribution systems. 1.

"The proposed innovation credit is centered on the use of masonry as a core material to enhance the performance of the building in various ways. While some of the resultant impacts of using masonry are commendable, the approach needs refinement. To warrant an innovation credit, quantifiable environmental benefit must be demonstrated through a comprehensive effort. The overall design approach and the list of 9 design elements (of which only 6 are cited as being the target) represents design strategies but do not necessarily lead to quantifiable environmental benefits beyond what is already awarded in existing LEED credits. Materials with recycled content contribute to MRc4. Energy savings is awarded through EAc1, and minimizing construction waste is awarded through MRc2. Though the cost saving strategies are applauded, they do not necessarily represent environmental achievement. In terms of replacing other structural elements such as wood or metal studs with CMU, it is not clear whether CMU, based on a life-cycle assessment, has a lower environmental impact than the other materials noted. Increased safety and better moisture control are beneficial design elements, but again, do not provide quantifiable environmental benefits. Similarly, enhanced acoustical performance is noted but has not been substantiated in terms of meeting acoustical requirements for specific spaces above conventional practice. The strategy of minimizing the use of construction materials may qualify for an innovation point if the reduction can be quantified and the applicant can demonstrate that an intentional, comprehensive effort was made throughout the project design to reduce construction materials. It must be clearly demonstrated that the strategy is above and beyond conventional practice. To substantiate the claim that choosing a CMU structural system represents a significant environmental benefit, the applicant could show that several structural systems were evaluated in a number of measurable categories to determine that the CMU system represents an innovative structural system. It should also be noted that the potential energy savings from using increased thermal mass is accounted for under EAc1 as per ASHRAE 90.1-1999. Changing R-value to reflect increased thermal mass is not an accurate method of accounting for the effects associated with mass, particularly the re-radiation of heat to space over time. R-value is an instantaneous phenomenon while thermal effects of mass are more transient in nature. In addition, the same effect that allows space with thermally massive construction to stay cooler also has the potential to cause radiant asymmetry and cause discomfort.

Products and materials are climate neutral when there is zero net greenhouse gases (GHG), such as CO2, from the entire life cycle of the product. The manufacturer calculates the total GHG impact utilizing life cycle analysis and then obtains carbon emission reduction credits (ERCs) such as through green power off-set purchases or carbon sequestration projects. The offsets must equal or exceed the GHG produced during extraction, processing, manufacture, transport and end use of a product, and be certified by a recognized third party using sound scientific and accounting principles. Climate neutral products must also deliver climate benefits ""above and beyond"" the standard version of these building materials, thus making them distinct and separable from all other sustainability features that these materials might also possess, such as recycled content. The development of market demand for climate neutral products provides several environmental benefits:  Reduce the GHG impact of building materials, and thus address the embedded climate impacts inherent in a building or interior fit-up materials.  Support USGBC\'s desire to move towards a more life-cycle based approach.  Reward proactive suppliers who take a climate leadership position with their products.  Ensure that climate benefits can be delivered on a credible, measurable and transparent basis.  Support the emerging market for carbon and other GHG trading. Requirements Specify 5% of the project\'s total material value with products or materials, which are third party certified as climate neutral. Submittals Provide a spreadsheet indicating the total material value of the project, including furniture and list each climate neutral material or product, indicating its material value in dollars, manufacturer and third-party certification. Calculate the percentage content of the climate neutral products and materials in relationship to the overall project material value. For products in which a portion of the total product is certified climate neutral, the calculation is based on the percentage of the climate neutral material in relationship to the total material or product cost. The percentage of climate neutral products must be greater than or equal to 5% of the total project value. See formula below: Total climate neutral material value ($) / Total project material value ($) = Project percentage of climate neutral materials (%) Provide cut sheets or other documentation demonstrating climate neutral compliance for each product. Potential Technologies & Strategies Research and specify products and materials that are climate neutral and have third party life cycle analysis and certification, which has determined that there is no net addition of greenhouse gases CO2, from their from their extraction, processing, manufacture and end use. Establish a project goal for climate neutral products and identify suppliers that can achieve this goal. Select products, which met all other project performance criteria including other environmental benefits, such as recycled content, distance from project site to place of manufacturer and extraction, VOC content and other measurable criteria. Supporting Documentation This innovation credit recognizes that tools are becoming available to more clearly state the environmental benefits of product and materials which offer a climate neutral stance in regard to greenhouse gas impact. For the purposes of this credit climate neutral products and materials are climate neutral when there is no net addition of greenhouse gases, such as CO2, from their extraction, processing and/or manufacture, or the manufacturer has purchased carbon or other greenhouse gas offsets such as through green power purchases. The Climate Neutral Network (www.climateneutral.com) is an independent non-profit organization which certifies climate neutrality under its Climate Cool brand mark for products, materials, processes and enterprises. The process of certification is rigorous, quantitative and based on established, clearly stated and repeatable standards and principles, similar to the rigor of the Greenguard and Forest Stewardship Council, although with a difference emphasis. Based on the particular products and/or amount of material specified, manufacturers can calculate the amount of CO2 permanently retired by the specific use of a Climate Cool product or material. The achievement threshold for this proposed innovation credit is 5% of total project material cost. Given the current limited amount of climate neutral products available on the market, this threshold is significant in that to achieve this level a designer will need to seek out and consciously choose these products and materials over their non-climate neutral counterparts. This threshold is the same as the current LEED-CI threshold for rapidly renewable materials, which currently represent a similar sized share of the building material market." "NOTE: This CIR and ruling can apply to projects registered in other rating systems other than LEED-CI. Your innovation credit proposal for use of climate neutral products is acceptable provided that: 1. Each third-party certifier of climate neutral products is a reputable, independent entity. An example of a climate neutral product certifier is the Climate Neutral Network. Purchases from carbon offset retail programs must be of the quality explained in Appendix A, below. Any credible environmental claim certifier can utilize the path described in Appendix B to certify climate neutral products. 2. The product\'s entire line of supply and manufacture must be climate neutral. It is not sufficient that a manufacturer purchase offsets solely for the units that are purchased and installed in a specific building; the continuous process that enables a specific product\'s availability to the market must be climate neutral. Minor variables such as color choices do not constitute a separate product. As already stated in your proposal, the full lifecycle of the products needs to be addressed and the products must also deliver climate benefits ""above and beyond"" the standard version of these building materials, making them distinct and separable from other sustainability features that these materials might also possess, such as recycled content.

The intent of the design team is to submit for an Innovation and Design Credit for an Educational Outreach Program. The project is a Car Wash & Maintenance Facility (hereafter referred to as the Facility) for a major Metropolitan Transit Agency. Due to the nature of the Facility the building is not generally open to the public. Use of the facility is limited to staff and organized visitations, thus onsite general public education would not be lucrative. Instead of an onsite educational program the Agency has accomplished / will be accomplishing the following: Educational Outreach: Project was featured in the Agency\'s ""Going Green"" brochure that was distributed on Earth Day. The use of captured rain water at the new Facility was a component of the Agency\'s ""Earth Day"" car posters distributed throughout the car fleet. The Agency\'s web site prominently features the Facility and has an animation of the Car Washer showing the captured / recycled rain water feature. Also, this website has recently been upgraded, as required by an Executive Order of the Governor, to be ""accessible"" to the hearing/visually impaired. Educational flyers on the Building will be available at the main lobby to visitors. Presentations: Presented a paper on the project at the Railroad Environmental Conference at UIUC in 2002. (University of Illinois, Urbana-Champaign) ""Green"" features of the new Maintenance Facility and Car Washer were part of the Transit Agency\'s ""Building for Tomorrow"" brochure and presentation at the UITP Conference on Sustainable Design. This was also presented at the APTA conference on the environment given in NYC. Tours: A delegation from MetroVal (Valencia Metro, Venezuela) went on a tour through the facility. There are also additional plans for a group of engineering students from Colombia University to tour the Facility. Awards: Applied for and received a ""Green Apple"" award (honorable mention) from NYC/DOB and the US-EPA for Green Building Design. Design Guidelines: Established Design Guidelines for ""Sustainability"" for implementation throughout the Capital Program that were a direct result of the Green Design efforts on this project. We propose to submit copies of all the brochures created as part of this outreach program as well as website information for viewing.

In order to provide a comfortable environment for building occupants, we have undertaken a wind tunnel study, which is not typical design practice for this type of building. Two approaches were undertaken in this wind tunnel study: numerical calculations and a wind tunnel test. The numerical calculations considered input parameters such as wind speeds, wind pressure coefficients, air temperatures, opening sizes for doors and windows, and different air permeability rates for the windows, doors and cracks. The wind tunnel test was conducted by creating a 1:150 scale model of the building complex based on the drawings of the architects. The model of the planned building complex was instrumented with approximately 500 pressure taps to test for pressurization, and it was exposed to 36 different wind directions spaced 10 degrees apart (0 to 360 degrees).

INTENT Reduce air pollution and health impact associated with construction transportation. REQUIREMENTS Project construction vehicles and on-site equipment are required to use B20 as primary fuel source. Supplier transportation vehicles would be required to provide proof of purchase for another trip equal or more in distance. CREDIT DOCUMENTATION SUBMITTALS - Written contract between construction managers and biofuel supplier to maintain provision of Biodiesel B20 storage on site. - Proof of purchase from sub contractors and material suppliers for distance travelled for said project. APPROACH AND IMPLEMENTATION All vehicles built after 1990 have the ability to run B20 without requiring any retrofit to use B20. On site storage of Biodiesel B20 upto 500 gallons will ensure all construction vehicles and on site equipment have direct access for refueling. Sub contractor vehicles need to submit receipts as proof of purchase. All other vehicles arriving at the site without using B20 will be required to purchase B20 for equal or more distance. Local biofuel suppliers have been identified and to be introduced to all subcontractors. A detailed education and training session will be carried out with General Contractor and sub-contractors prior to commencement of the project. Partnership with local groups like Space Coast Clean Cities Coalition, Federal Department of Energy and Clean-Cities will introduce the idea of using bidiesel to the community. ENVIRONMENTAL ISSUES - 1 unit of energy used to produce biodiesel B100 gives output of 3.24 units of fuel energy, diesel outputs 0.8 fuel energy. - Petroleum based diesel is a non-renewable fuel. - Construction vehicles travel through local communities causing smog and ground level ozone due to the air pollutants and particulate matter emitted. - EPA\'s study carried out in 2002 notes B20 blend of biodiesel vehicles are observed to emit 20% less Hydrocarbons and 12% less Carbon Monoxide (CO), and 12% less Particulate Matter. - Non-road engines are also expected to emit less Particulate Matter (PM) and CO when operated on Biodiesel B20 blend. - Biodiesel is produced from agricultural resources. They are renewable, local and cause less pollution in production and transportation. Purchase and use of Biodiesel supports the local economy and farmers growing the crop. HEALTH ISSUES - As per research carried out by EPA, the impact of biodiesel on total toxics is beneficial, i.e. total toxics are on average reduced when biodiesel is added to conventional diesel fuel. - B20 reduces emission of cancer causing polycyclic aromatic hydrocarbons (PAH) and nitrated polycyclic aromatic hydrocarbons (nPAH) as compared to diesel operated engines. - Other chemicals borne off petroleum based diesel like formaldehyde and benzene are absent in Biodiesel."

Permanent electrical service has recently been installed and ownership will begin purchasing 35% of the electricity supplied to the construction site from renewable sources through a contract with the local utility company. Renewable Energy Certificates will be purchased in the amount to offset a similar percentage of electricity consumed prior to installation of permanent electrical services, tracked through billing statements from the utility company. Electrical consumption is conservatively estimated to be approximately 600,000kWh for the remaining 11 months of construction. 210,000kWh (35% of total) will be supplied via a contract with the local utility to be from a Green-e approved resource. This total is commensurate with the calculated 110,000kWh/yr for this project that will be provided per the requirements of EA-Credit6 (220,000kWh over 2-years, as a comparison), and therefore we believe this to be a significant contribution to the project\'s sustainable design goals." "As total power consumption is under the purview of the owner/contractor during construction, one Innovation and Design credit can be earned for providing green power (per EAc6 definition) for 100% of the total actual electricity consumed during construction. For an Innovation and Design credit this calculation must include all areas of the building, including those outside of the Core and Shell areas.\n\n **Update October 1, 2013: This ruling is now applicable to 2009 versions of the LEED BD&C Rating Systems" "None" "None" "X" "LEED Interpretation" "1838" "2007-11-15" "New Construction, Commercial Interiors, Core and Shell, Schools - New Construction" "IDc1: Innovation in Design" "We are seeking an Innovation in Design credit for implementing a comprehensive water filtration system that will reduce occupants\' exposure to contaminants generally present in tap water. In the same way that Indoor Environmental Quality credits address the reduction of airborne contaminants found in building interiors, this system addresses waterborne contaminants that are commonly found in local water supplies. This system also obviates the need for occupants to purchase bottled water products, which can help reduce the over 60 million plastic bottles that are discarded everyday in the United States. The system we are considering combines an extremely water-efficient building-wide first stage water filter that removes 100% of particulates 10 microns or larger and approximately 50% of particulates smaller than 10 microns, with a secondary stage consisting of individual ""point-of-use"" filters in the apartment kitchens. The point-of-use filters use a multi-stage filtration system that includes pulverized activated carbon which significantly reduces organic chemicals and a membrane that removes particulates 0.5 micron and larger. By preventing particles larger than 10 microns from ever reaching the .5 micron kitchen filters, the primary filtration system significantly extends the effective life of the secondary filters (approximately a 300% increase in filtration cartridge longevity), thus reducing maintenance and ensuring a higher flow rate and quality of water. The secondary system has been tested and certified by NSF/ANSI to reduce VOCs and trihalomethanes (THMs) which the EPA classifies as a ""probable human carcinogen,"" by 99.86 percent. Trihalomethanes are the byproduct of municipality-introduced chlorine interacting with organic material in the source water. It also has been shown to reduce cysts, such as Cryptosporidium, by 99.99 percent. A 1993 Milwaukee outbreak of Cryptosporidium left 400,000 ill and 70 dead. This is likely to become more important since water borne disease is seen as a probable consequence of the increasing hydrologic events and flooding caused by climate change. The following list of contaminant reductions has been certified by NSF/ANSI (42 & 53): - Chlorine: Avg. Reduction-96.8% - Volatile Organic Chemicals, including Trihalomethanes (THMs): Avg. Reduction-99.86% -Asbestos fibers >10 micrometers in length: Avg. Reduction-99.86% -Cysts: Avg. Reduction-99.99% -Chloroform (VOC surrogate chemical): 98.6% This combined filtration system improves occupant health and reduces the amount of resources typically required to achieve this level of water purity.

Part of the site was previously developed and contained two houses. In lieu of demolition of these structures, one of the houses was moved from the property - being sold to a 3rd party who has moved the house to a new location and is continuing to use the house as a residence - thereby extending its useful life and purpose. The second structure was in poor condition and was unlikely to continue to be used as a residence. This structure was donated to the local municipality for use by the public safety/fire department as an educational/training tool as part of a live fire training exercise. This of course means that the house was burned as part of the training exercise and is no longer on the property. Our question is two fold: 1. The house that was moved rather than demolished and diverted from the waste stream continues to be used as a house and serves a family of four. We consider this a benefit as a family is provided affordable housing without the use and extraction of additional material resources. Also, because the house was moved it is being used in its entirety - diverting even more waste than would normally be realized through job site recycling. Should we include the weight of this house in our calculations for credit MR 2, and if so, how should we best estimate the weight of the structure? We will not be able to separate the weights of the various materials and components but will rather need to estimate the weight of the house en masse and list as a separate line item. or, should we apply for an Innovation and Design Credit for the reuse of the house? 2. The house that was donated to the local municipality for use by the public safety/fire department as an educational/training tool also diverted waste from the landfill. We understand that incineration of building materials and waste is not considered to meet the intent of MR 2 unless it is used as a biomass fuel generation source as determined by the ruling on 3/23/2004. However, use of this structure benefits the public good - by providing firefighters necessary educational and lifesafety training experience so that they are better prepared to fight fires and rescue people in danger - the use of the house in this manner thereby helps to save lives and extend the public good beyond the material value of the structure. All of the burned material was removed from the site prior to the contractor\'s mobilization and control of the site. May we apply for an Innovation and Design Credit for this work? Supporting documentation will include narratives, a statement of activity by the public safety/fire department and an environmental report stating that the house contained no hazardous materials at the time of the fire fighting exercise." "The applicant is proposing two measures: to include a relocated house in the calculations for MRc2 or to receive an innovation point for this measure, and to reuse an existing house for a fire department training use and achieving an innovation point using this strategy. The relocation of the first structure mentioned warrants an innovation point, as this reuse measure achieves a higher environmental impact than recycling of the materials of the house alone. Alternatively, the house can be included in MRc2 calculations; if the total project\'s diversion rate for MRc2 is 95% or higher, an ID point for exemplary performance can be pursued. The proposal for the second structure (donation for public safety/fire department use) can be included in the MRc2 calculations but does not warrant an innovation point alone. Consulting a structural engineer on the weights of both houses for these calculations is encouraged in order for the weights of the materials to be the most accurate."

Additional measures were taken to assure the storm water management system was designed to maximize treatment of storm water runoff from adjacent properties. DESIGN APPROACH The proposed new construction is located on 13.7 previously developed acres consisting mainly of hard-turf soccer fields, gravel parking, and a small abandoned building. Existing site best management practice\'s (BMP\'s) consist of one vegetated swale and there are no rate or volume control measures. Adjacent to the site, along the south and east borders, are 5.0 acres of residential development and county road that currently receive no treatment. The proposed 13.7 acre site and the adjacent off site 5.0 acres share a 48"" culvert located in the southeast corner of the proposed site. The proposed on-site storm water management system consists of 4 infiltration/settlement basins, 2 vegetated swales and 1 detention pond. The system is designed to route water from the building roof and parking lots through pre-treatment infiltration basins located on the east and west ends of the parking lot. Water from the west end parking lot infiltration basin will outlet to a vegetated swale which will flow to the detention pond on the southern edge of the site. Water from the east end parking lot infiltration basin will outlet to another infiltration basin near the southeast corner of the museum, which then outlets to a vegetated swale before entering the detention pond on the southern edge of the site. The additional 5.0 off-site acres of storm water runoff will be rerouted to enter the site at the infiltration basin at the southeast corner of the site. As explained above, after treatment in this infiltration basin the runoff flows through a vegetated swale and in to the detention pond. All storm water will then pass through one additional infiltration basin before exiting the site. PROPOSED COMPLIANCE After the construction of the project and its site appurtenances are completed, the impervious areas of the site will consist of a 0.9 acre building footprint, 1.4 acre parking lot, and 1.2 acres of trails, patios, turfed surfaces, and sidewalks. The remaining 10.2 acres of the site will consist of various types of native and adaptive vegetation along with BMP\'s. The 5.0 off-site acres will be rerouted to be incorporated in the BMP\'s of the proposed site. The project team intentionally designed the storm water management system to maximize treatment of on-site storm water runoff and to handle 5.0 additional acres of runoff (approximately 35% additional area) from an off-site residential area and section of county road currently receiving zero treatment. Through hydraulics/hydrology models we have confirmed that the site will reduce peak discharge rates for the 1 and 2 year 24 hour storm events by 30%-15% respectively. The site will also reduce discharge volumes for the 1 and 2 year 24 hour storm events by 50% and 25% respectively. Through water quality models we have confirmed that the site will reduce the total suspended solids by 85% and total phosphorus by 60%. We are confident the combined interaction between the infiltration basins, swales and the detention pond assures that the project site exceed LEED goals and intent for both storm water quantity and quality.

INTENT: To minimize the total quantity of new gypsum wallboard (drywall) used in acoustically sensitive buildings through accurate performance specifications, enhanced materials, and efficient design. The innovative approach will be applied to walls and partitions specified as acoustically high performance for interoffice privacy and/or noise control (sound transmission class 50 or higher). In some cases, a single layer of soundproof drywall can be used to replace up to five layers of traditional drywall. This product and design approach will result in a significant reduction in the total embodied energy of the materials used in the building. (The BEES software from NIST has reported that a single panel of drywall represents between 150,000 to 300,000 Btu\'s of embodied energy). REQUIREMENT: Minimize amount of building materials used by designing walls meeting the sound isolation requirement with QuietRock soundproof drywall. Demonstrate at least a 20% savings in the quantity of gypsum wallboard used compared to the baseline design using conventional, techniques and materials. SUBMITTALS: Architectural plans, details and specifications, a letter signed by the architect or acoustical engineer outlining the acoustical performance requirements identified in the design, the measures implemented in the approach, photographs of soundproofing measures under construction, bills of sale of soundproofing drywall materials purchased, and calculations demonstrating at least a 20% savings in the quantity of drywall used compared with conventional, baseline construction techniques and materials. DESIGN APPROACH: For a two-story multi-purpose commercial building, areas of the floor plan require additional noise control (due to amplified lecture halls or private workspaces). Well established performance specifications required that these walls perform to an STC 50 or higher. These partitions have been designed using QuietRock, an innovative soundproof drywall, so that an over 20% material reduction is achieved. The process was as follows: 1. All walls with a sound isolation requirement have been reviewed by a qualified professional to assess/confirm minimum performance requirements and alternate, material-optimized assemblies were recommended. 2. Acoustical walls requiring multiple layers of gypsum drywall have been redesigned using layer(s) of soundproof drywalls in their place. 3. Architectural details have been added that address acoustical seal and closure best practices for optimal sound isolation. 4.

The project is located in downtown Seattle, Washington. The project has three above-grade, podium level courtyards that are composed of concrete pavers, raised planting areas, and a small amount of wood decking (ipe). The project has strong design intent focused on minimizing the heat island effect and thus is pursuing and will likely achieve the Sustainable Sites credits for Heat Island Effect for Non-Roof (SSc7.1) and Roof (SSc7.2). We believe the project also satisfies the intent of the Exemplary Performance pathway for Heat Island Effect Non-Roof since 100% of the parking is underground. However, we are confused about how best to demonstrate that accomplishment due to the complexity of our project, contribution of multiple strategies, and imprecise language in the reference guide. Please provide clarification on how to document this credit, given the circumstances described. Even though the roof already satisfies the criteria for SSc7.2 Heat Island Effect, Roof, the roof is reexamined in determining compliance with the Exemplary Performance pathway for SSc7.1 since portions cover the underground parking. As previously mentioned, the project will easily achieve the 50% threshold for SSc7.1, by either or both of the available options. However in order to achieve the SSc7.1 Exemplary Performance threshold of 100%, it seems the project is required to demonstrate that any portion of roof that covers parking has a minimum solar reflectance index (SRI) of 29. We believe that the project satisfies the intent of the credit but is having trouble matching the circumstances of the project to the submittal requirements. As you will read below, only by the strictest definition of the requirements, does the project fail to satisfy the requirements. The following four ways demonstrate both in isolation and in cooperation why our project should be awarded full credit for the Exemplary Performance for SSc7.1: 1. Area-weighted Average SRI - The area-weighted average SRI value for surfaces that are above underground parking is 75, which is composed of the following three elements: a. Roof - White TPO membrane, SRI = 82, Area over parking = 36,483 sf b. Courtyard - Concrete pavers, SRI = 40, Area over parking = 4,742 sf c. Courtyard - Ipe decking, SRI = 27, Area over parking = 1,634 sf The area of vegetation and a corresponding SRI is excluded from the Area-weighted Average SRI. However, it is worth noting that vegetation on the courtyards covers 4,535 sf (9.5%) and further reduces the heat island effect and would increase the average SRI if vegetation could be valued using the SRI metric. The percentage of the total area covering underground parking for each of the four materials is as follows: a. Roof - White TPO membrane, percentage of total roof area: 77% b. Courtyard - Concrete pavers, percentage of total roof area: 10% c. Courtyard - Vegetation, percentage of total roof area: 9.5% d. Courtyard - Ipe decking - percentage of total roof area: 3.5% 2. Shading: The three podium-level courtyards are located one story above street level and are significantly shaded by five levels of residential units that surround them. Due to this, the courtyards are further mitigated from any heat island effect by shading. In fact, using the LEED prescribed shading calculations (qualifying area shaded is the average of areas shaded at 10 a.m., noon, and 3 p.m. on the solstice), even though they only technically apply to the Option 1 compliance path, demonstrates that shade from the building will cover 47 % of the total courtyard area, and 51% of the total wood decking area. This further reduces the influence of the wood decking in contributing to the heat island effect. In addition, tree plantings in the larger courtyard will also contribute to shading of the pavement. 3. The LEED-NC Reference Guide gives an explicit definition of what qualifies a project for the Exemplary Performance Pathway for SSc7.1, ""Project may be awarded an innovation point for exemplary performance by demonstrating that.2) 100% of the on-site parking spaces have been located under cover"". There is no mention of the requirement that ""Any roof used to shade or cover parking must have an SRI of at least 29"" as is mentioned in the credit language. Furthermore, the roof in question was not merely put in place as a parking shade, but instead to cover the building, which is already included in SSc7.2 Heat Island Effect, Roof, which this project is already achieving. 4. Amenity Space: The project is sited in a dense urban area, where residential development is part of a strategy to create vibrant neighborhoods. In creating such communities, it is important to provide outdoor amenity spaces for the residents that allow for a respite from the hectic pace of urban life. These courtyards provide simple outdoor gathering spaces comprised of a variety of materials which allow residents to relax in a visually rich outdoor space within the harsher city environment. As a footnote, the Ipe wood decking in question was sent for testing at a laboratory, at a not insignificant cost, to determine its actual SRI value and its impact on the heat island effect. Since new Ipe decking has very different properties than Ipe decking that is a few years old due to the effect of weathering (the brownish wood weathers to a silvery gray over time), a partially-weathered sample was tested. It is our belief that this was the appropriate approach as for most of the life of the building, the weathered Ipe decking will be in place, and only for the first few years would the decking exhibit its as-installed brownish look. Since the sample available for testing was only partially weathered, we believe this further strengthens our argument, as over time the SRI value will slowly increase, likely moving from its tested value of 27 and eventually crossing the threshold of 29. In conclusion, the Taylor 28 project has located 100% of its parking underground to avoid paving even a single black asphalt parking space, is located in a dense urban environment where amenity spaces-especially those with natural wood elements-are limited and essential to community and producing peaceful outdoor spaces, and has multiple strategies in place to respond to the intent of reducing the heat island effect. The wood decking is only slightly under an SRI of 29, comprises only 9.5% of the over-parking roof area, is 51% shaded via LEED shading methodology, and the remaining roof areas and vegetation will also drastically reduce the heat island effect-combining to nearly trivialize the contribution of the Ipe decking to the heat island effect, while providing a great amenity space and natural element in a dense urban environment. For these reasons and everything described above, we believe that this project should be awarded both Heat Island Effect credits as well as an Innovation in Design point for Exemplary Performance for credit SSc7.1." "The project team is requesting clarification on the requirements for exemplary performance for SSc7.1. The project team is correct - the Reference Guide states that exemplary performance for SSc7.1 may be awarded an innovation point for exemplary performance by demonstrating that, per option 2, 100% of the on-site parking spaces have been located under cover.

AMD\'s telepresence system will utilize broadcast-quality cameras and optics to deliver seamless, no perceived delay collaboration around the world, eliminating the need for airplane and automobile travel for in-person meetings. Telepresence recreates face-to-face meetings virtually so employees and partners can build relationships, review products and documents and make decisions faster without leaving their offices. Halo users can interrupt one another, express their emotional reactions when they feel them, and otherwise, act as they would in a regular face-to-face meeting. The end result: everyone feels as if they are in the same room, when in reality, they may be thousands of miles away on different continents. By reducing employee travel, these systems minimize the greenhouse gas footprint for Halo-enabled buildings while improving worker productivity, satisfaction and health. In addition, Halo rooms use US EPA Energy Star rated plasma displays and revert to standby mode when not in use, reducing energy use by 40%. AMD\'s offices are spread around the country and around the world. ""Americans make more than 405 million long-distance [over 50 miles] business trips per year, accounting for 16% of all long-distance travel"" (from ""America on the Go"", U.S. Department of Transportation Bureau of Transportation Statistics, October 2003). Halo rooms have the potential to significantly reduce the number of long-distance trips made by business travelers and the resulting greenhouse gas emissions. Bill McGee writes in USA Today of a Consumer Reports study on carbon footprints for air travel: ""We used 11 leading carbon calculators to assess our footprint using the standard measurement of pounds of CO2. For a flight from New York to Los Angeles, we found that one passenger generated anywhere from 1,924 pounds to 6,732 pounds."" (from ""On the Road with Bill McGee"", USA Today, online: http://www.usatoday.com/travel/columnist/mcgee/2008-01-30-fuzzy-math_N.htm) These statistics indicate that a single ""Halo Studio"" meeting with a mix of attendees from around the country and within Austin can divert roughly 15,512 lbs. or 7.8 tons of CO2. Over the course of a year, this single ""Halo Studio"" could divert hundreds or even thousands of tons of CO2. (Calculation: 4 cross-country round trip plane flights= 1,924 lbs. CO2 x 2 trips x 4 attendees = 15,392 lbs. CO2; 4 short distance car trips = 15 lbs CO2 per mile x 2 trips x 4 attendees = 120 lbs. CO2; total = 15,392 + 120 = 15,512 lbs. CO2) Telepresence systems are offered by several companies including Hewlett-Packard, Cisco, Teliris and Polycom. AMD\'s Halo system was developed by Hewlett-Packard. These systems are distinct from traditional videoconferencing due to the immersive quality of communication provided by the telepresence solutions. For example, the offerings from HP utilize multiple display screens, broadcast quality cameras, a fiber optic network and include technology that enable people to connect to multiple sites around the world at the same time, offering everyone a ""same-room"" communication experience. There are up front investment requirements, including the cost of the studios (pricing varies depending on the type of telepresence solution, but top of the line HP studios, for example, list for $349,000 USD per studio) and some systems also have a monthly service fees.

Reduced Embodied Energy - Reduction in Material for Interior Finishes Intent: To reduce the total energy use of a building\'s lifetime by reducing the initial and recurring embodied energy through the reduction of materials used in interior finishes. Requirements: Total initial and recurring embodied energy associated with interior finishes should be reduced by 40%. The requirement can be met through reduction in use of interior finishes compared to conventional practices and/or use of lower embodied energy products for interior finishes. This project reduces the relative proportion of interior finishes (compared to a more conventional design) to reduce material usage. This produces initial embodied energy savings and energy savings associated with recurring refurbishment and maintenance activities. The project applies finishes to 72% of floors, 74% of walls, and 29% of columns compared to a conventional Czech Republic building, which is 100% finished. Ceilings of the project (excluding glass areas) are 100% finished. Analysis of energy savings related to reduction of interior finishes is based on life cycle assessment (LCA) studies of embodied energy use in office buildings. For the purposes of this analysis, energy use consists of initial embodied energy (energy to create the building), recurring embodied energy (energy to maintain the building over its lifetime), operating energy (energy to operate the building) and demolition energy (energy to demolish the building upon end of lifetime) (as proposed by Cole and Kernan, 1996). Initial embodied energy applies the initial embodied energy coefficient to finished areas. It compares the design to the baseline case, which assumes 100% finished interior surfaces. The baseline case represents typical construction practices for Czech Republic office buildings, while the design case utilises the project\'s finished areas. Initial Embodied Energy Coefficient: Carpet (floors) 0.273 GJ/m2 Plaster (columns) 0.0114 GJ/m2 Metal stud (24"" OC) gypsum board & latex paint (walls/ceiling) 0.341 GJ/m2 Source: University of Bath, 2006 and Athena Institute EcoCalculator, 2007. Total recurring embodied energy (for a 60-yr service life) is calculated based on the relative significance of recurring embodied energy compared to initial embodied energy in the life cycle of energy uses. The baseline and design cases are calculated by applying the initial embodied energy coefficient to the finished areas described in the total initial embodied energy, and subsequently recurring embodied energy, as follows: Associated Initial Embodied Energy: Baseline - 67,937 GJ Design - 33,820 GJ Associated Recurring Embodied Energy: Baseline - 90,356 GJ Design - 44,981 GJ Total Embodied Energy of Applied Finishes: Baseline - 158,203 GJ Design - 78,801 GJ The project shows 50.2% savings on total embodied energy related to finishes against the baseline. Typically, initial embodied energy of materials for interior finishes makes up ~13% of the total initial embodied energy of concrete office buildings. Thus, the reduction of materials for finishes represents 6.5% (50.2% x 13%) savings on initial embodied energy. Recurring embodied energy of materials for interior finishes represents ~30% of total recurring embodied energy across the 60-yr lifetime. Thus, the reduction of materials for finishes represents 15.1% (50.2% x 30%) savings on total recurring embodied energy in the project. Total savings across total life cycle including operational energy: Total Initial Embodied Energy Savings 6.5% x 17% = 1.1% Total Recurring Embodied Energy Savings 15.1% x 23% = 3.4% Total Saving Across Whole Life Cycle 4.5% The approach indicates that significant savings can be achieved by reducing the quantity of materials for interior finishes. The approach is logical and replicable for other buildings." "The applicant is requesting the approval of an innovation credit based on the use of interior finishes with lower embodied energy, as compared to a conventional baseline. Although the project team has demonstrated that they have used materials with lower embodied energy than the baseline, it is not clear that embodied energy is a good indicator of total environmental impact. Embodied Energy is a single attribute describing how much energy is required to make a unit of material. While energy consumption typically has an associated environmental impact, the reduction of embodied energy alone does not identify or equally quantify the downstream environmental impacts, such as carbon dioxide emissions, air pollution, water eutrophication, etc. In a comparison of two materials in which one product uses more energy than the other, it does not automatically mean that the product with lower embodied energy is more environmentally friendly than the other. There are other factors that must be considered, such as the type of power that was used in the production of the material, e.g. green power compared to coal fired or nuclear generation.

The principal focus of the energy consuming systems is to create a precise simulation of a wide range of ambient conditions and simulated building loads on the tested equipment to meet national and international testing protocols. In addition, the facility tests the equipment to research and develop innovative technologies for the HVAC industry. Control of the testing conditions is critical to the function of the facility. The facility\'s large process heating and cooling plants are used to simulate heating and cooling loads on the tested equipment. The subsequent heating and cooling energy created from the tested equipment is then rejected to the environment. This research and testing system is highly energy intensive. Recognizing the opportunity for energy use reduction, the owner\'s research and development team and the project\'s design team developed a process heating and cooling system that reduces the energy use of the system while maintaining the ability to simulate ambient conditions and building loads. Heating and cooling energy created by tested equipment is captured and reused in the process heating and cooling plants. Closed-loop heat recovery systems connect evaporator and condenser systems of the process plants to the tested equipment to reduce energy usage. Variable flow pumping and varying temperature control provide the necessary control functions for testing. For this project, the process energy associated with the research and testing system is greater than 90% of the total energy load. If the reductions in process load are not included, the opportunities for energy reduction are minimized. The project utilizes commercially available energy reduction strategies, including enhanced envelope systems, premium efficient chillers and high efficiency boilers for process loads, high efficiency comfort heating and cooling equipment, variable frequency drives on fans and pumps, and higher efficiency lighting systems.

Insufficient information has been provided above regarding the process energy savings strategies to verify whether they would qualify for credit using the Exceptional Calculation Method under EAc1. However, any modeling approach used for the building systems should include the following: 1. Tested equipment should be modeled using identical types, quantities, efficiencies, controls, and pump power in the Baseline and Proposed Case. 2. In the Baseline Model (prior to applying any exceptional calculation measures), the process heating and cooling plants for simulating test conditions should be modeled with the identical quantities and capacities of equipment in the Baseline and Proposed Case, identical pump power, identical controls, and identical schedules of operation. However, equipment efficiencies for the Baseline Case process equipment should reflect those listed in Tables 6.8.1A-J. 3. Other baseline assumptions used for the Process heating and cooling plants should reflect standard practice for newly constructed facilities with similar functions. These assumptions should be modeled identically in the Baseline and Proposed Case, and then modified in the Proposed Exceptional Calculation Method model. The Exceptional Calculation Narrative must provide sufficient information to verify that the efficiency measures modeled are not standard practice for this type of facility. 4. The Proposed Case Exceptional Calculation Method Model should reflect any parasitic energy associated with waste energy recovery, but this parasitic energy should not be reflected in the Baseline Model.

GHG emissions are the largest environmental impact associated with burning fossil fuels, and purchasing high-quality greenhouse gas emissions offsets will significantly and quantifiably reduce greenhouse gas emissions beyond purchase of renewable power, further reducing the climate impact of a building\'s energy use. Therefore we propose an Innovation in Design Credit for balancing out the greenhouse gas impacts of a building\'s natural gas use as follows: Intent: Reduce climate impacts associated with a building\'s fossil fuel energy use. Requirement: Participate in a program with rigorous standards that balances out 100% of the climate impact of the building\'s actual natural gas use by purchasing an equivalent number of high-quality greenhouse gas emission reductions for a period of two years. Submittals: Provide a copy of the energy bill verifying enrollment in the program; provide a letter from the owner committing to participation in the program for a period of at least two years. Design Approach: Participate in Pacific Gas and Electric Company (PG&E)\'s ClimateSmartT program (http://www.pge.com/climatesmart), through which we achieve a greenhouse gas offset equal to 100% of the emissions from our building\'s natural gas use. 100% of our building\'s natural gas supply comes from PG&E, and the greenhouse gas emissions associated with our natural gas use are calculated based on the actual amount of natural gas our building uses each month, and the greenhouse gas intensity of PG&E\'s natural gas supply. The independently certified emission rate is 13.446 lbs carbon dioxide (CO2) per therm. We pay PG&E to purchase greenhouse gas emission reductions on our behalf from new projects (after December 14, 2006) that would not have otherwise occurred. The projects from which PG&E purchases reductions must demonstrate that they are real, additional, verifiable, and permanent, and the projects must not be counted towards any GHG emission reduction caps specified in any mandatory local, state, national or international GHG regulatory structure or cap-and-trade program, or in any voluntary cap-and-trade program. The projects are also independently verified, audited, and registered with the California Climate Action Registry (""Registry"") and all emission reductions are permanently retired in the Registry\'s publicly accessible Climate Action Reserve tracking database. Projects must be based in California and meet the stringent requirements of one of the Registry\'s project protocols, which include capturing methane gas from dairy farms or landfills and conservation-based forest management. All projects that PG&E invests in absorb or reduce GHG emissions from the atmosphere; the amount of emission reductions purchased through the program on our behalf is equal to the actual amount of GHG emissions from our building\'s natural gas use. Purchasing a percentage of renewable energy under the Green Power credit lowers the climate impact of energy use only by the amount of green power purchased.

This strategy must include the four components listed below.\n 1. Identify activities and building functions for which ergonomic enhancement (i.e., ergonomic strategies which exceed standard industry practice) is both possible and desirable through education and equipment. -. Building users should be consulted on their preferences wherever possible. NOTE: Project teams are encouraged to consult one or more of the existing ergonomics standards and guidelines when identifying ergonomic enhancement opportunities. For computer workstations, these include the BIFMA G1, the ANSI/HFES 100-2007, and CSA Z412-00. The US Department of Labor Occupational Safety and Health Administration (OSHA) has developed ergonomic guidelines specifically for the following industries: Shipyards, Poultry, Retail Grocery Stores, Nursing Homes, and Meatpacking. OSHA also provides helpful information for many other industries in addition to those listed here (please see the Resources section below).\n 2. Define a set of performance goals and expectations for the ergonomics strategy that address productivity, comfort, and health. Develop a plan and design process to meet them. Provide procedures to track and report the results of the ergonomics strategy, ensure that the performance goals have been met, and identify areas of potential improvement. These should include the following actions: a) Make the performance goals and ergonomics plan available to building users b) Provide a feedback system to collect anonymous responses and respond to them. This should be informal and ongoing. c) Maintain ongoing building user access to appropriate ergonomics METWA's, furnishings, and accessories and education. d) Conduct a survey of user satisfaction. This should be more formal than the feedback system, and occur periodically. The survey must be collected from a representative sample of building occupants making up at least 30% of the total occupants.\n 3. Provide machine, equipment, tools, work-aids (METWA's), furnishings, and accessories that reduce the risk of work-related musculoskeletal disorders and are acceptable to a wide range of building users. In a setting where building users that spend 50% or more of their time at computer workstations, the following four areas must be addressed: display, computer peripherals (keyboard/mouse), work surface, and chair. Computer workstations include areas in which workers interact with screens or monitors of any kind. \n 4. Provide ergonomics education to building users Provide at least two opportunities for building users to understand and take advantage of ergonomic features in their environment. At least one of these opportunities must be interactive, and at least one must include an explanation of the provided METWA's and furnishings, preferably by the manufacturer. Post-education evaluations must be conducted. Education opportunities may include, but are not limited to: a) Participatory classroom sessions conducted by an ergonomics professional b) Access to literature on products and basic ergonomic knowledge relevant to the building user's tasks c) Repetitive or regularly-scheduled workstation evaluations d) Interactive internet-based products such as assessment and training tools e) Hands-on experiences, such as access to the showroom of an ergonomic furnishing supplier\n\n Submittals:\n 1. Provide a narrative that speaks to the requirements listed above. It should include: - descriptions of the steps the project team has taken to identify ergonomic enhancement opportunities. - a sentence or two verifying that it is possible to exceed standard industry practices to achieve an ergonomically superior workplace. - descriptions of the performance goals and expectations, and the steps the project team has taken to meet them - descriptions of the procedures put into place to track and report the results of the ergonomics strategy. Describe how each of the required actions, listed in #5 of the requirements section, will be take place. Describe the collaboration with the management team that will carry out these procedures. - description of how purchased METWA's and furnishings will benefit the building users as they conduct routine tasks and activities, the selection criteria used for choosing the products (i.e., how the safety and health of the building user was considered), and how the products will accommodate a wide range of size needs. Size needs can typically be met by buying products that come in 'families' (small, medium, large) or are highly adjustable. - descriptions of two ergonomics education opportunities made available to building users, including the objectives and content.\n 2. Provide a list of purchased METWA's and furnishings that minimize the risk of work-related musculoskeletal disorders. Include cut sheets and manufacturer information for each. For project certifying under LEED for Existing Buildings : Operations and Maintenance, at least one survey must be conducted during the performance period, and documented survey results and corrective actions to address issues identified through the surveys must also be provided. Potential Technologies and Strategies: In general, consider METWA's and furnishings that will: - reduce awkward, non-neutral work postures (e.g. neck, shoulders, hands-wrist, low back, elbows, lower extremities) - reduce duration of sustained/static work postures (e.g. leaning forward, elevated arms, continuous grip) - reduce grip and pinch forces associated with required tasks (e.g. correct tools) - reduce the repetition and duration of tasks, especially those with non-neutral postures and/or higher forces - reduce contact stress - resting soft tissues of the body on hard or sharp surfaces. To address the four required areas for building users that spend 50% or more of their time at computer workstations, consider the following strategies: Display adjustability - The display centered directly in front of the body. - The top of the display screen placed no higher than the eyes. - The ability to place the display screen 18 to 36 inches from the eyes - Control over the tilt angle of the screen and its' position on the work surface - The capability to position the display low enough to accommodate individuals with bifocals or progressive addition lenses (PALs). This may be significantly lower than eye height reduced glare - The use of technologies such as flat-screen or anti-glare devices - The display positioned such that light sources will not create glare Peripherals - Paper documents placed on a document holder immediately to the left, right or below the display - The keyboard positioned so the home row (row with F and J keys) is no higher than the elbow - The ability to adjust the keyboard angle and set the slope of the keys flat, if so desired - Enough room for the mouse or pointing device to be used adjacent to the keyboard (left, right or in front). If a separate adjustable keyboard support is used it must have space specifically designed for using a mouse or pointing device; preferably the mouse pad should have the capability to be positioned flat if the keyboard is tilted - The arm used to control the pointing device supported, either on the work surface or armrest of the chair - Ergonomically correct keyboards, mouse, phones and other supporting peripherals purchased when possible Surface - Enough work surface to properly support the computer and peripherals. Provide a surface with minimum dimensions of 28 inches wide by 24 inches deep - Enough clear space under the surface to allow the legs and feet to be positioned in multiple postures - Furnishings in multi-occupant workstations that allow the user to control surface and support heights, with surface height initially at proper seated elbow height. If workstations are single-occupant it is acceptable for facilities management to adjust the heights of surfaces Chair - Range of chair types or chair features that optimize employee fit and task requirements. - Chairs with a wide range of adjustibility For building users that work in an industrial setting, consider: - Height adjustable work-surfaces (e.g. desks, work benches, fume hoods) - Pneumatic vs. electric vs. manual tools, material handling aids, such as lifts, height adjustable pallet jacks and hand trucks. - Range of hand and power tools sizes and weights that improve employee fit and function while reducing ergonomic risk factors, for example: grip diameter, multi-finger activation and vibration isolation For ergonomics education provided to building users, consider including information on: - The possible causes of musculoskeletal discomfort - Changing the workstation or work habits if discomfort is experienced during or after work - Benefits of taking work breaks either through altering tasks performed or leaving their workstation - Benefits of resting the eyes every 20 minutes - How to properly position and adjust display height and angle, keyboard height and angle, mouse location, use of task light and chair adjustments - Acceptable postures for the head, neck, shoulders, upper arms, wrists, back, legs and feet - Benefits of regularly changing posture either through adjusting the furnishings or altering the tasks performed - How to manage glare on the computer screen - A point of contact if discomfort becomes frequent (multiple times per week) References: Federal Occupational Safety and Health Administration http://www.osha.gov/SLTC/ergonomics/index.html, Human Factors and Ergonomic Society http://www.hfes.org, Canadian Standards Association http://www.csa.ca, The Business and Institutional Furniture Manufacturer's Association http://www.bifma.org/, National Institute for Occupational Safety and Health http://www.cdc.gov/niosh/, American Conference of Governmental Industrial Hygienists http://www.acgih.org/, International Organization for Standardization www.iso.org please reference the ISO 9241 standard, The Hewlett Packard Safety and Comfort Guide http://www.hp.com/ergo/ HealthyComputing.com, http://www.healthycomputing.com/office/setup/, 'Effect of Office Ergonomics Intervention on Reducing Musculoskeletal Symptoms ' Amick B., Robertson, M., Derango, K., Bazzani, L., Moore, A., Rooney, T., Harrist, R., , Spine 2003, 23: 24, pp 2706-2711.

While Energy & Atmosphere Prerequisite 1 refers to the building envelope as ""an important component of a facility which impacts energy consumption, occupant comfort and indoor air quality,"" this prerequisite does not provide guidance or measurable goals for improving the building envelope through commissioning. In order to address items that go beyond the scope of EAp1 such as quality control, maintainability, rain penetration control, mold prevention, building longevity, and ultimately building sustainability, we propose an innovation strategy using NIBS Guideline 3-2006 to direct the envelope commissioning process. This strategy shall follow commissioning metrics including documentation, performance criteria, test procedures, and checklists. Specifically, the process shall explore requirements such as the impact of the building exterior enclosure on visual comfort, and IAQ. Documentation including a summary of the assumptions for accessibility to building exterior enclosure systems (maintenance, cleaning, etc.), and allowable ranges of operations for the building exterior enclosure (number of days/year that the owner is willing to accept condensation, etc), quantify goals and provide the owner with enhanced control of the building. With incorporation of the building envelope into the commissioning process, we propose this innovation credit will improve the inter-relationship of the exterior enclosure system with other building systems and ultimately ensure adequate and quality functioning of the exterior enclosure system throughout its expected service life. INTENT Verify that the building exterior enclosure systems are designed, installed, and perform according to the OPR, BOD, and construction documents. BENEFITS OF COMMISSIONING THE BUILDING ENVELOPE Benefits of building envelope commissioning include: better building documentation, improved coordination of envelope components, enhanced resistance to water infiltration, improved maintainability, improved indoor environmental quality and verification that the systems perform in accordance with the OPR. REQUIREMENTS 1. Adherence to commissioning requirements and activities. Inclusion of building envelope quality assurance criteria and documentation emphasizing: a. Visual comfort and indoor air quality b. Rain penetration control c. Durability d. Constructability e. Maintainability f. Sustainability 2. Field review of aesthetic and functional mock-up(s), including review of both the unique interface conditions and general interface conditions. Verify the design intent is met and the level of water and air tightness of the exterior enclosure is as specified in the OPR. 3. Periodic construction monitoring, especially during roof transition/ roof termination installations, initial installation of sealants, and the specific project interfacing conditions (below grade waterproofing, differing material interfaces - green roofs and fenestration expansion joints, etc). 4. Performance testing of building envelope, including but not limited to: a. Infrared scanning of constructed building to identify thermal leakage. b. Water infiltration testing to identify leakage and prevent heat, air, moisture, and mold (HAMM) issues which will improve IAQ. c. Additional testing as identified per envelop system. 5. Validation that performance parameters for each exterior enclosure system meet the OPR. 6. Development of a Systems Manual for each major building exterior enclosure system, including but not limited to: a. Roof/Garden Roof b. Exterior walls c. Windows d. Doors e. Sealants and expansion joints f. Control joints g. Flashings 7. Training: maintenance of the exterior enclosure (window washing, inspecting and repairing joints/weather-tight seals, etc). We intend for the Enhanced Building Envelope Commissioning credit to follow the same basic scope parameters as EAp1 (design review not required, etc.). Given this, we propose that this credit will not be contingent on any other credits including EAc3. Please confirm all the above strategies could constitute a valid ID credit. If denied, please state under which conditions the credit could be achieved." "The project team has proposed an ID credit for commissioning the building envelope.

This innovative technology is the only standard based natural gas and LPG (propane gas) system manufactured, designed sized and installed under the ANSI LC1 certification process. CSST is IAPMO, ICC and CSA listed; IFGC, UPC and NFPA-54 approved as a gas-piping material. This system is installed with fewer fittings eliminating leak paths in the natural gas or LPG (propane gas) system, thus making the system safer within a structure. The inherent flexibility and light weight will reduce costs and help prevent job related accidents. Most manufactures\' of CSST incorporate a fitting which uses a metal to metal seal with no gaskets or O-rings and features which allows for maintaining of the integrity of the Polyethylene jacket protecting the system from corrosion and harsh environments. The Polyethylene jacket, as required by ANSI LC1, is constructed to meet the ASTM E84 requirement for Fire /Smoke (25/50) making the system safer in the event of fire. This innovative technology eliminates the need for welding of natural gas and LPG piping and the dangers associated with such procedures, such as toxic fumes from welding gases, flux and brazing rods and smoke and soot caused by welding. This technology reduces respiratory problems associated with inhaling the toxic fumes resulting from welding of natural gas and LPG piping and eliminates the dangers of fire associated with welding of natural gas and LPG piping. It also eliminates personal injury associated with the use of welding and threading equipment. It is our intent to submit for this credit as a system which exceeds the LEED-NC performance as related to a safer environment during construction and safer system within a structure, for the life of the structure." "The project team is requesting clarification as to whether the use of Corrugated Stainless Steel Tubing for distribution of natural gas and LPG warrants the award of an Innovation in Design credit. While the benefit of reduced exposure for construction workers and building occupants are laudable, this concern is addressed in EQ Credit 3.1: Construction IAQ Management Plan - During Construction.

The project is an office building for the State of California, housing the Department of Education. Prior to the design and construction of the new office building, the site was a surface parking lot with a few trees surrounding the site on the perimeter. Adjacent to the project is a six-story apartment building and across from the site is the California State Capitol mall, a park like setting, with many differing plants and tree species represented. Contained within the project is a small pocket park, which separates the office building from the adjacent apartment building. The park was selected as a site for the State Arts in Architecture program, and a nationally known artist was selected for the art commission. In response to community outreach efforts, and in response to neighborhood concerns about open space, the Design Team for the project worked with the artist to develop a unique response. The team worked on the development of the landscape design using specific features listed below, coupled with the strategy of an ecologically based landscape management and maintenance program. The team also sought to use the project landscape as a means to educate and promote the use of organic based urban landscaping and agricultural farming and the use of beneficial insects as a substitute for pesticides. Features of the Ecologically based Landscape Design and Pest Control include: - An interpretive fountain and sculpture that uses gray water and that reflects the culture and environs of the Sierra Foothills; - Native plant materials, selected for their appropriateness to the climate, low water requirements, adaptation of the native cultural landscape of the region, and aesthetic appeal. Plant material was also selected for its ability to provide habitat for beneficial insects; - Organic landscape specifications including soil mix management, sub-surface drip irrigation, gray water and organic fertilizers; - An irrigation system that utilizes high efficiency drip technology and reduces water consumption by 63%; - A fertilizing and feeding plan, which includes a biological nutrient management using compost tea, injected into the irrigation system; - The project also has a retail component, designated as restaurant space. Once restaurant tenants are identified, the Design Team will work with the tenants to develop a composting process to recycle organic waste streams from the building and the restaurant tenants, including food waste, landscape pruning, etc. - Training of the building and grounds maintenance staff to monitor for insect pests and plant disease. Training the staff to release beneficial insects as the primary means of pest control, and training the staff to use soft pesticides and to avoid toxins. - Educational stations with plaques and graphics delineating the ecological methods utilized, beneficial insect and plant identification and their symbiotic relationships. - Consultation on pest problems and supplying beneficial insects to the project for the duration of the two-year warranty period. Question: Could this interpretive pocket park, developed with neighborhood concerns, educational goals and coupled with organic practices be considered an innovation point?" "Yes, this project could attempt an innovation credit by addressing the education value of the ""green"" features of the park. A previous LEED Interpretation on the issue of an educational program in relation to buildings to achieve an innovation credit: please see Inquiry Number 0121-IDc11-092801. To summarize the earlier ruling, your project must be ACTIVELY instructional by including two of the three following elements: 1) comprehensive signage program to educate; 2) manual, guideline or case study to inform the design of other projects; 3) educational outreach program or guided tour focusing on sustainable living. As outlined in your inquiry, most of these elements are planned or already incorporated into the program in a very comprehensive way that reaches across many credit categories. Rather than focusing on a sustainable building education program as described in the previous inquiries, this project could focus on a sustainable site educational program that highlights green features throughout, as suggested in your narrative. You must be vigilant in your documentation of the measures described and provide adequate photos/drawings and other documentation along with narratives explaining your intent, the requirements, the submittals and the design approach, as directed in the Reference Guide.

By providing the car sharing program MORE employees can utilize public transportation because employees will be less tempted to drive their own cars to work for out of office meetings/business that may not be accessible by public transportation and will also reduce parking demand in the vicinity of the tenant space. The tenant owner would pay for a monthly public transportation pass (or equivalent) to employees and also offer a third party car sharing program in which cars are strategically placed around the city; accessed electronically by participants; booked online; available 24 hours a day seven days a week and utilize hybrid cars. Below is an outline of the potential Innovation Credit. Intent: Reduce pollution and land development impacts from automobile use. Promote use of public transportation and car sharing. Proposed requirements for compliance: Tenant to promote use of public transportation by offering to employees a stipend to cover the cost of a monthly public transportation pass cost or equivalent. AND Offer a third party car sharing program to employees for business related travel. The car sharing program will utilize fuel efficient hybrid automobiles and demonstrate that there will be enough cars available in the area to supplement the need from the tenant space. Proposed submittals to demonstrate compliance: Car sharing lease agreement, area plan showing location of cars realtive to tenant space, and signed letter from owner stating that they will provide a stipend for employees to purchase a monthly public transportation pass or equivalent. Technologies and Strategies: Perform a transportation survey of potential tenant occupants to identify transportation needs. Choose a building near mass transit and located near a car sharing program.

Narrative Describing Project\'s Approach to the Credit: Formaldehyde is a well-known carcinogen and is highly toxic, having been linked to respiratory ailments and throat cancer. Further eliminate the use of urea formaldehyde from the building by eliminating the use of insulation containing urea formaldehyde. The project will be specifying a batt insulation (both thermal and sound attenuating) that is formaldehyde-free. Batt type (blanket) insulation is used extensively throughout this project. Also, the project will be using a foamed-in-place insulation injected into the cores of the masonry block after masonry work has been completed. Many foamed in place insulations used in masonry applications use a urea formaldehyde resin as one of their components. These are classified as urea formaldehyde foam insulations (UFFIs). UFFIs were banned in 1982, but later that ban was over turned in 1983. Since then, UFFIs have been banned in several states.

The project has used an exterior coating system with a higher heat reflectance value than the values of conventional coatings. This credit interpretation request is to inquire about submitting the coating system used, to apply for a credit for reduced heat island effect for non-roof surfaces. The Total Solar Reflectance (TSR) values of the exterior coatings used in the building were tested using a D&S reflectometer according to ASTM C1549-04. The TSR value of the BML-01 ""White"" color used was 82.9% and the TSR value for the PPG522-3 ""Water Chestnut"" color used was 74.5%. To prove merit for one point under LEED, we have followed the guidelines of the LEED reference guide to document Sustainable Sites Credit 7.1-Heat island effect non-roof. The baseline case and design case were calculated using the exterior wall surface area and 50% of the site hardscape area. The baseline case was calculated using 43.7% solar reflectance for conventional beige paint to match the color used in the building and 35% for new gray concrete hardscape. The design case was calculated using 74.5% solar reflectance for the Water Chestnut coating used and 5% for new asphalt hardscape. Using Ecotect and site specific data the building was modeled with the correct north orientation. Ecotect calculated the incident solar radiation that strikes the north, south, east and west walls, and the hardscape surfaces annually in Wh. The incident solar radiation value for the four facades and the hardscape were added, and multiplied by the solar reflectance values to determine the site reflected solar energy. The analysis showed that 61% of solar energy would have been reflected using conventional paint and new gray concrete, but instead we are reflecting 77% of the total solar energy incident on the site using a coating with a higher heat reflectance value. We would like to know if this approach of using exterior coatings with higher reflectance values to lower heat island effect on non-roof surfaces will be acceptable to document one innovation in design point."

As a result, over 300 PV panels were incorporated into the project at no cost to the Owner. The PV wall system includes both structural butt-glazed panels and captured panels, which kept intact the original design intent. Question: Would the seeking out of funding sources for green features be considered an innovation point?" "No, securing additional funding for green building features does not constitute an innovation. Rewarding projects that buy down first cost through incentive programs is contrary to the LEED objective of demonstrating green building performance within conventional cost assumptions.

"None" "None" "X" "LEED Interpretation" "2477" "2009-02-06" "New Construction, Core and Shell, Schools - New Construction" "IDc1: Innovation in Design" "INTENT The construction phase has many opportunities to improve and should be more greatly weighted to drive new innovations and processes. With most of the scoring based on design aspects, there is not a strong push for contractors to implement new strategies. This is further evidenced in the fact that there are few credits that are construction activity based. One area that has not been addressed is the impact of temporary buildings servicing the project. Many of the same challenges, and thus opportunities, exist during the construction process as they do during the design, construction and life of a building. We propose the use of ""green"" trailers during construction on LEED projects to reduce the ecological footprint of these facilities. APPROACH Through the use of green trailers we will reduce energy use, raise awareness and educate our staff and project partners, improve occupant comfort, and reduce the ecological footprint of the trailer\'s infrastructure (i.e fewer replacements of lighting, heating equipment, etc.) The trailer will, at minimum, be constructed with the following components:  motion sensors for lighting in the project offices  T-8 lighting fixtures bulbs for reduced electricity use,  programmable thermostats for thermal comfort control  increased weather stripping to reduce heating and cooling loss  Increase window area to allow for daylighting in the space Further Measures: Project trailers will also aim to reduce water usage, either through the installation of added low-flow fixtures or alternatively through a written Water Conservation Plan for the project site and trailers. Air quality is being addressed through improved filtration and material waste reduction through an Office Supply Selection & Waste Reduction plan for the project offices. Proposed Submittals: - Proof of onsite signage regarding water conservation or water restriction guidelines/regulations when low-flow fixtures not installed - Comparisons of energy use between regular and ""green"" trailer - Documentation of energy bills (or statement from client regarding increased energy cost when power being drawn from existing system) providing level of use - Narrative on Further Measures and use of green trailers in general We believe that Green Trailers are a true innovation in project delivery that not only aims to reduce energy use onsite and throughout construction, but also educate and change behavior through the consistent application of LEED principals across all project activities. Through the development of three different trailer models of increasing efficiency and overall performance, we also endeavor to push the industry as a whole toward more efficient equipment and offices during the construction process." "The proposed innovation credit is based on the merits of using ""green"" trailers during the construction phase. The ""green"" trailers will incorporate sustainable measures, such as motion sensors for lights, efficient lighting, programmable thermostats, increased weather striping, increase window area, low-flow fixtures, and increased filtration. Other policies such as a Water Conservation Plan or Office Supply Selection & Waste Reduction plan will also be adopted. It is envisioned that these collective measures will also provide educational opportunities about green design. While these measures are commendable, it is unclear if these measures as described will result in significant and measurable environmental benefits. The energy savings and water savings anticipated for the trailers will need to be significant relative to the overall amount of energy and water used during the entire construction phase, and should not be isolated to the amount used for the trailers alone. Further, the listed energy efficiency measures do not appear to address the overall building envelope (including glazing type) for the trailer, the HVAC systems, or address consideration for passive strategies, such as optimum site orientation and layout, natural ventilation, effective daylight strategies (balancing light while minimizing heat gain). The strategies identified also do not address the type of materials used for the trailer, or the use of on-site renewable energy sources. If additional measures like these were implemented, demonstrating significant, measurable environmental benefits (relative to the overall construction process), an innovation credit would likely be granted for these ""green"" construction trailers.

In the end, a 16,000 s.f. project was able to leverage over 200,000 s.f. of LEED Gold. Background While St. Stephen\'s was in the design process for its LEED project, a local developer proposed to build on the vacant lot located one property lot away to the south. The project team learned that the developer was preparing to present the building design drawings at an upcoming Harrisburg Planning Commission meeting, during which variances would be requested for significantly exceeding the height and setbacks allowed by city zoning code. St. Stephen\'s publicly opposed providing a variance for these excesses primarily because the neighboring building would cut off access to sunlight that the St. Stephen\'s project team was planning to collect for day lighting and PV arrays. Given the developer\'s and St. Stephen\'s prestige in the community, St Stephen\'s requested a meeting with the developer to discuss the issues to see if the height could be lowered or setbacks aligned with zoning requirements. The outcome was that the developer agreed to meet with the St. Stephen\'s team. Initially the developer brought in his architect to explain the designs. The St. Stephen\'s team also presented its sunshade studies. The developer agreed to examine stepping the new building back between the 5th and 8th stories so that the St. Stephen\'s complex would not be in shadow so often. Ultimately, no accommodations for setbacks were provided and it was acknowledged that the developer had no intention of making it a sustainable or LEED building. Soon thereafter, the developer divulged that the tenant would be Pennsylvania Housing and Finance Authority (PHFA). Resulting LEED Achievement During the time period that followed, St. Stephen\'s thought that there was an opportunity in this to leverage their position and negotiate a greater good by supporting the proposed zoning variances. At the time in 2002, very few PA state agencies were pursuing LEED certification for their buildings, with the exception of DEP. The project team thought that fighting the developer and PHFA might ultimately gain the 16,000 s.f. St. Stephen\'s school daylight, but rather than be ""penny wise and pound foolish"" the project team realized that there would be a much greater benefit if they could convince a public agency to make greater accommodations that would benefit the larger Harrisburg and Pennsylvania community in the name of environmental responsibility. They believed this could be especially important given that the agency is the PHFA that would deal with the future housing in the state. As a result, the St Stephen\'s project team invited the PHFA representatives to join in the discussions with the developer. During the subsequent meetings, the St. Stephen LEED design team educated the building\'s developer and its tenant, the PHFA, about sustainable design buildings and negotiated a formal agreement. This agreement accomplished 1) a minimum silver rated building for a state agency, 2) a smaller building that was ""stepped back"" so that it would relate better to the surrounding small and historic buildings within the neighborhood and not leave them all in shadow, 3) higher density in the neighborhood by allowing a smaller setback and taller building than zoning permitted, and 4) greater access to solar energy for the Episcopal school by granting St. Stephen\'s rights to harvest solar energy from the PHFA roof, which is much larger than St. Stephen\'s and would see more daylight than St Stephen\'s would otherwise due to surrounding buildings and trees. As a result of the St. Stephen\'s project team efforts, the developer and PHFA were prompted to enlisted their architect to redesign their project to include sustainable design features and achieve the minimum LEED silver rating that St. Stephen\'s demanded as part of the negotiated agreement, which is why sustainable design became one of the inherent development goals of the PHFA building. The PHFA building ultimately received LEED Gold Certification in September 2005." "The USGBC does not consider this proposal alone to merit an innovation credit.

REQUIREMENTS Utilize digital media to expand upon the delivery of public education through: - Providing context to the LEED plaque (to be located in the lobby) by playing back the video on a flat screen adjacent to the plaque. This will provide expansive meaning to a plaque that will be viewed by thousands of people each year - including many who are not familiar with USGBC or LEED. Additionally, this would also reduce the traditional use of lobby paper products to tell the green story. Such paper products can sometimes go underutilized and/or are quickly discarded. - Educating visitors on the LEED and non-LEED green attributes of the resort by the daily and multiple playbacks (minimum 4 times each day) of the video on the resort\'s dedicated in-room television channel. This would achieve USGBC\'s goal of educating visitors to the project. - Educating new employees by playback of the video as part of their initial training and orientation.

The bottled water industry has grown substantially in the past decade. About 74% of Americans drink bottled water; one in five drinks only bottled. Demand is outstripping recycling capacity. According to the Container Recycling Institute, each year an ever smaller proportion of plastic bottles are recycled; from 2 out of 5 in the mid \'90s, to only 1 out of 7 today. Seventy million water bottles are disposed of each day, with 60 million going into landfills, oceans or incinerators. Our project plans to implement a two-stage water filtration system that provides water purity equal to or better than bottled water. Implementing water filtration technology is an answer to the severe environmental impact of bottled water, because it reconciles people\'s desire for pure, safe drinking water with the imperative of reducing waste. By installing two-stage water filtration - first at the main (point-of-entry, POE) and then downstream within kitchen cabinets (point-of-use, POU) -- and educating our occupants about the health and environmental advantages of the system, we anticipate a dramatic reduction in the purchase of bottled water in our building and associated waste. The two-stage configuration, and the specific equipment selected, are designed so as to minimize environmental impact by 1) at POE using negligible water for self-cleaning, and 2) at POU achieving significant filter cartridge longevity. Requirements: - Provide building-wide point-of-entry water filtration that removes particulate contamination equal to or smaller than 10 microns; AND - Provide point-of-use water filtration at 0.2 micron (fine enough to remove bacteria) and NSF/ANSI Standard 42 and 53 certified. AND - Educate building occupants about the system, how it works and its substantial environmental benefits. Benefits: - Obviate the need for bottled water by providing high performance and low impact two-stage water filtration that will substantially reduce the amount of plastic water bottles going to waste from our building. - Reduce the exposure to potentially harmful waterborne contaminants for the entire population through universal access to filtered water. - Reduce the energy required to heat water by screening out particulates that over time negatively impact system efficiency. - Reduce the amount of pollutants released in the manufacture and transportation of bottled water attributable to our building. There are 70 million bottles of water consumed in the US per day. Dividing that number by the total population of approximately 306,000,000, means that 23% of the US population is drinking one bottle of water a day. We believe this estimate to be conservative and that widespread adoption of two-stage water filtration could have a much bigger impact, especially in areas with known water quality problems. We estimate that our 1200 apartment project will have 2130 occupants. Therefore, 23% of 2130 = 479 people drinking one bottle of water a day times 365 days/yr = 174,835 bottles for this one building resulting in a reduction of 149,858 (6 out of 7) bottles going to landfill, oceans or incineration. New occupants will be given an orientation session at the time of lease by the property manager explaining the dual system, the POU maintenance requirements and why the cost and environmental impact of bottled water can be avoided in the building. The tenant environmental guideline will also detail the environmental impact of bottled water and describe the system benefits and performance. The filtration system will be a highlighted feature on all leasing and green building tours."

We have used our experience with delivering consulting services and training on project management technologies to develop this customizable, easy-to-use Microsoft SharePoint-based tool; it is a private, secure, project-specific Web site. Our innovative solution helps project participants efficiently share and process vital documents like drawings, RFIs and contracts--all while slashing printing, shipping and travel energy- and resource-usage. Owners and contractors from multiple organizations can collaborate to make informed and timely decisions when they exchange and store data in a project\'s own secure, neutral, Web-based \'office,\' rather than using paper to print draft after draft of large files (i.e. drawings, specs, contracts, change notices, payment estimates, submittals, RFIs, correspondence, safety bulletins, contact directories, schedules, calendars, announcements, transmittals, progress photos, progress reports, meeting minutes, etc.) Any and every process our project requires can, and will, be incorporated into our Virtual Project Office. For example, when the project team is ready to request bids from contractors, we will use our paperless, Web-based Virtual Project Office to issue Requests for Proposals (RFPs), provide bidding instructions, and announce up-to-date questions and answers. We will be able to post downloadable construction documents such as drawings and project specs. Contractors will then upload their bids electronically, automatically notifying the bid manager--via e-mail--of their submission. Housing all bidding information in one secure, collaborative online workspace dramatically reduces the typical energy and resource consumption of the bidding process, supports confident contract-award decisions, and gets the project off to a successful start. We will use our collaboration solution to:  Connect team members across organizational and geographic boundaries so they can collaborate regardless of their time and place of work--without spending energy, resources, money or time on paper, shipping or travel.  Streamline review-and-approval processes (i.e. RFPs, RFIs, submittals, change notices, payment estimates, etc.) and make them electronic, eliminating the energy costs and delays of printing and shipping multiple copies of paper documents back and forth among project participants.  Notify collaborators automatically via (paperless) e-mail when virtual documents are added and updated.  Reduce energy- and resource-consuming litigation by mitigating all parties\' risk exposure with automatic auditing of revisions, ball-in-court requests, and responses.  Protect private information using our secure, neutral collaboration platform, limiting each party\'s vulnerability to energy- and resource-consuming claims.

You mention that previous projects have achieved an innovation credit by calculating the amount of material recycling achieved by MRp1 and then calculating the percent improvement over that recycling rate they achieved by recycling/reusing additional materials.\n\nOur question relates to applying this credit to a university campus where many of the facilities are shared. Our project is a renovation of a residence hall. In addition to recycling the basic recyclables required in MRp1, we offer collection of wooden pallets, old electronic equipment, furniture, batteries and other materials. We also have an extensive, university-wide composting program that collects organic cafeteria scrap and landscaping waste. The cafeteria is a separate building that serves students, faculty and staff on campus. The landscaping waste is collected from the entire campus, including our project site. In fiscal year \'05 every building on campus collected the basic recyclables mentioned in MRp1, collecting 195 tons of material (173 tons paper, 11 tons cardboard, and 11 tons cans and bottles).

Description: One of the program goals for this project was to eliminate the use of polyvinyl chloride (PVC) to the extent possible. The Pentagon Renovation Program required in their statement of work that PVC should be eliminated unless: a. There was not an alternative product b. Alternative product selection compromised performance c. Alternative product selection had an unacceptable impact to budget or schedule (note that the program did pay more for some non-PVC products). The purpose for attempting to eliminate PVC is as follows: Toxicity liabilities: The manufacturing of PVC burdens the environment with numerous environmentally undesirable byproducts. - The lifecycle of PVC production creates four persistent organic pollutants that are identified for phase-out under the United Nations Environment Program POP Treaty. - Ethylene dichloride (EDC) and vinyl chloride monomer (VCM) which are released to air and water during manufacture of PVC are toxic and carcinogenic. - When PVC is incinerated as part of a Municipal Solid Waste strategy, toxic dioxins are formed as a byproduct of incomplete combustion. - Chemical additives called phthalates are added to PVC to enhance performance characteristics such as flexibility. These compounds are typically DEHP and MEHP which affect bronchial contracting receptors and thereby generates a hyper reactive condition in the lungs. Because these additives are not chemically bonded, they tend to leach out of the PVC causing indoor air quality to be compromised. Lack of market stewardship: According to the Worldwatch Institute, global PVC production exceeded 25 million tons in 1999. By 2002, it is estimated that the figure will rise to 33 million tons. Accordingly, although 250 million tons of PVC are in use today it is estimated that over 100 million tons have been landfilled or incinerated. The production of one ton of chlorine requires about 3,000 kilowatt-hours of electricity. Since 40 percent of chlorine is attributed to PVC production, the energy burden for PVC is about 1,800 kilowatt-hours per tons of product. Because the PVC industry does not promote any kind of product stewardship initiatives, from the perspective of both resources and energy consumption, there is no credible proactive effort to enhance the properties of PVC to characterize it as a sustainable material. Reclamation deficiencies: In the document Characterization of Municipal Solid Waste, the EPA estimates that 970 thousand tons of PVC were generated in 1999 of which only a ""negligible"" amount was recovered. So small is PVC recycling, in fact, the amount recognized for discards equals the amount of material generated. Because PVC must be produced with a number of additives such as lead and cadmium to produce unique characteristics, it is difficult and expensive to reclaim resins. Most recycling that does occur is post-industrial which means that nearly everything that has entered the consumer market will eventually be landfilled or incinerated. The project team did evaluate the environmental impacts of those materials that were specified in lieu of PVC. For this project, a number of different products were specified where PVC might have conventionally been a ""default"" selection. These included, but were not limited to: - High density polyethylene (HDPE), for wastewater, potable water, foundation drainage and sprinkler systems. - Bentonite waterstops in lieu of PVC waterstops. - Linoleum (rapidly renewable material), in lieu of PVC flooring - Carpet tile with recycled PVC backing Could an innovation credit be achieved for the elimination of PVC (including the use of contract language to eliminate PVC) to the extent possible on this project?"

To help resolve how the LEED program will deal with this issue, the Technical and Scientific Advisory Committee has been charged with reviewing the information sources available and to advise the LEED Steering Committee on whether (and if so how best) to give credit under LEED for the exclusion or minimization of PVC products in LEED buildings.

The entire line of ER3 Modular Tile products are SCAS NSF-140 \'Platinum\' certified. The Sustainable Carpet Assessment Standard (SCSA) is the first nation-wide certification program that evaluates all measurable aspects of the environmental performance of carpet products. SCSA seeks to promote products that provide comprehensive environmental, economic, and social benefits while protecting and enhancing the needs of future generations, public health, welfare and the environment over their full commercial cycles, from raw materials extraction to final disposition, and ensuring that such products are also equivalent in performance and quality to other carpet products. Carpet products that carry SCSA \'Gold\' and \'Platinum\' level certification have the added credibility of being subject to regular, independent third-party audits. Upon completion of the trial use and comment period, SCSA will be revised as necessary and submitted to the American National Standards Institute (ANSI) for approval as an American National Standard. In the baseline LEED Rating Systems, carpet products are evaluated per their indoor VOC emissions, plus the extent to which they might have some recycled content, regional material content, and/or rapidly-renewable material content, thus contributing to the associated Materials & Resources credits. While valuable, such criteria are somewhat limited in scope. By contrast, SCSA takes a broad, life-cycle-based approach to product evaluation, thoroughly examining such varied issues as the environmental impact of the manufacturing processes, social concerns such as the rights and working conditions of company employees, and what happens to carpet products at the end of their useful lives. The draft Sustainable Carpet Assessment Standard consists of the following major categories: Safe for Public Health and Environment Addresses the reduction of inventory pollutants that adversely impact public health and the environment, over the entire supply chain of any given carpet product. Energy & Energy Efficiency Addresses energy use and greenhouse gas emissions associated with carpet production and recognizes the use of renewable energy sources and implementation of conservation and efficiency measures. Bio-based, Recycled Content or Environmentally-Preferable Products Addresses more environmentally-benign feedstocks used to manufacture carpet products and is applicable to either natural or synthetic fiber construction. Manufacturing Addresses company-wide environmental stewardship via reporting and certification protocol, such as adoption of an environmental policy, use of an environmental management system (EMS) and public declaration of performance as per ISO 14001. Reclamation and End-of-Life Management Addresses product reuse and reclamation opportunities as well as installation and maintenance procedures that extend product system life. We feel that this strategy warrants a LEED IDP point because SCAS sets a high benchmark for environmental accomplishment, is comprehensive in nature, and specifically references many other third-party standards to set specific performance criteria. Furthermore, there is precedence for acceptance of such holistic standards for IDP points. In recent CIR Rulings, USGBC has favorably recognized whole product evaluation standards such as MBDC C2C, the California Gold Standard and the Climate Neutral Network Climate Cool Certification. The Project Team hopes that adoption of such a rigorous standard in the carpet industry will stimulate development of similar standards to guide other industries involved in the manufacturing of building products and materials.

This revitalization is a multi-phase project involving several buildings and parking structures and will act as a community showcase for energy and environmental leadership. As part of this effort, every attempt has been made to maximize the potential for energy efficiency and for renewable energy in the form of solar photo-voltaic (PV) panels. The existing buildings that make up the Civic Center Complex are currently individually metered for electric services from the local utility, PG&E. The key buildings involved in the first phase of work are the City Hall and the Hall of Justice which will have 2000kva combined electrical loads. Our project will include installing a 12kV system to loop several existing buildings together including these two buildings, providing two primary benefits to the City: (1) it will consolidate several buildings\' loads to a common meter at a higher voltage service, and (2) allow us to install additional PV panels. The latter is important as the Hall of Justice lacks adequate available roof space for much PV. By looping this building with other nearby buildings with the 12kV system, we can install PV on another building on the loop, the Auditorium, and permanently assign the generated power to the Hall of Justice. The Auditorium provides ample rooftop area to site enough PV panels to meet at least 7% of the proposed load for the Hall of Justice. An individual meter for the PV system will track its production of electricity. The 12kV loop also provides measurable innovative energy efficiency performance benefits by replacing the single source feeds that are now fed from the existing Hall of Justice at 208/120V with a primary based distribution system to each building. This will reduce the line losses in the Complex saving considerable energy not accounted for in other energy efficiency calculations for this project. Based on voltage drop calculations and a rough distance between the involved buildings, the energy savings will be on the order of 100 KW at full facility load. The 12kV loop is also being designed to accommodate future buildings, greatly adding to the reduction of total line losses when complete and allowing us greater flexibility for future siting of additional PV. Our question is if the 12kV loop will qualify as an innovation credit for innovative energy efficiency performance under the LEED guidelines." "Request Denied.

The move would produce immediate benefits to both the IT department and Harris construction as a whole. Virtualization is a proven software technology that is rapidly transforming the IT landscape and fundamentally changing the way that people compute. Today\'s powerful x86 computer hardware was originally designed to run only a single operating system and a single application, but virtualization breaks that bond, making it possible to run multiple operating systems and multiple applications on the same computer at the same time, increasing the utilization and flexibility of hardware. In essence, virtualization lets us transform hardware into software. The use of software such as VMware ESX will allow us to transform or ""virtualize"" the hardware resources of an x86-based computer-including the CPU, RAM, hard disk and network controller-to create a fully functional virtual machine that can run its own operating system and applications just like a ""real"" computer. Multiple virtual machines share hardware resources without interfering with each other so that you can safely run several operating systems and applications at the same time on a single computer. Power Consumption Energy consumption is a critical issue for Harris IT today, whether the goal is to reduce cost, save the environment or keep our datacenter running. In the United States alone, datacenters consumed $4.5 billion worth of electricity in 2006. Industry analyst Gartner1 estimates that over the next 5 years, most enterprise data centers will spend as much on energy (power and cooling) as they do on hardware infrastructure. Virtualization allows us to reduce our energy costs and consumption by 80%. Most servers and desktops today are in use only 8-15% of the time they are powered on, yet most hardware consumes 60-90% of the normal workload power even when idle. VMware virtualization has advanced resource and memory management features that enable consolidation ratios of 15:1 or more which increase hardware utilization to as much as 85%. Once virtualized, a new feature of VMware Distributed Resource Scheduler (DRS) called Distributed Power Management (DPM) monitors utilization across the datacenter and intelligently powers off unneeded physical servers without impacting applications and users. With VMware virtualization we can dramatically reduce energy consumption without sacrificing reliability or service levels. Reduce the Environmental Impact of IT For Harris this equates to every server virtualized, we can save about 7,000 kilowatt hours, or four tons of CO2 emissions, every year. This means our 12 servers could be reduced to 4 servers through virtualization. The reduction in servers along with the savings in electricity with the reduced cooling requirements equate to as savings of 49,000 kilowatt hours, or 28 tons of CO2 emissions every year. Currently 60 cents of every dollar spent for data center energy is used for cooling equipment and not powering it. Conclusion In short the five major reasons to virtualize the Harris IT servers are: Server Consolidation and Infrastructure Optimization: Virtualization makes it possible to achieve significantly higher resource utilization by pooling common infrastructure resources and breaking the legacy ""one application to one server"" model. Physical Infrastructure Cost Reduction: With virtualization, we can reduce the number of servers and related IT hardware in the data center. This leads to reductions in real estate, power and cooling requirements, resulting in significantly lower IT costs. Improved Operational Flexibility & Responsiveness: Virtualization offers a new way of managing IT infrastructure and can help IT administrators spend less time on repetitive tasks such as provisioning, configuration, monitoring and maintenance. Increased Application Availability & Improved Business Continuity: Eliminate planned downtime and recover quickly from unplanned outages with the ability to securely backup and migrate entire virtual environments with no interruption in service. Improved Desktop Manageability & Security: Deploy, manage and monitor secure desktop environments that end users can access locally or remotely, with or without a network connection, on almost any standard desktop, laptop or tablet PC. Virtualization is a technology that can benefit Harris Construction. The employment of virtualization solutions will reduce IT costs while increasing the efficiency, utilization and flexibility of their existing computer hardware."

This credit interpretation was filed under ID because there was not an appropriate category. We are requesting a ruling on the application of NCv2.2 for the future interior fit-out of a project owned, occupied and operated by a single tenant. Our project is a four story, 155,000 sq.ft, commercial office building in the midst of construction. Although the project was initially intended to be complete in its entirety, the client has chosen to isolate a portion of the interior fit-out on the 4th floor for future fit-out. All exterior roof, walls, glazing, sun screens, etc. for the entire building and the interior fit-out for floors 1, 2, 3 and over 50% of the 4th floor will be installed prior to occupancy.

The General Contractor, Hensel Phelps Construction Company, has developed and implemented a program to monitor construction pollution prevention and ensure soil erosion and sediment controls during construction. Hensel Phelps developed a trial program in 2007 to assess their effectiveness in assuring compliance with specified pollution prevention strategies. Results of the trial indicated dramatic performance improvements in the implementation of pollution prevention practices during construction. Consequently, the company has adopted this program as standard practice for all of its projects. The Prerequisite for Sustainable Sites requires prevention of: 1. Loss of soil during construction by stormwater runoff and/or wind erosion, including protecting topsoil by stockpiling for reuse, 2. Prevent sedimentation of storm sewer or receiving streams, and 3. Prevent polluting the air with dust and particulate matter. While all construction sites attempt to fulfill this prerequisite by putting in place controls, these precautions are rarely monitored and thus not repaired when necessary. Hensel Phelps Construction actively evades this negligence by implementing a much more thorough Stormwater Pollution Prevention Plan. The program contains a comprehensive plan for ensuring compliance through extensive training, routine audits, documentation, and maintenance. An HPCC employee not on the project team is employed to audit the site\'s SWPPP Program. Three to seven days after the initial assessment, a follow-up inspection is conducted. Throughout the lifetime of the project, at least one HPCC employee that is part of the construction crew is assigned to oversee the upkeep of the soil erosion and sediment control measures on a monthly basis. This surveyor will walk the site to ensure that the control measures are in good shape. Documentation guidelines and performance metrics are also included to allow for thorough monitoring and assessment of the plan\'s effectiveness. Reports from the third party inspections of the SWPPP are forwarded to the Vice President, General Superintendent, Project Superintendent(s) and the Area Superintendent(s) to ensure that it receives the appropriate attention. Then the monthly inspections are recorded in detailed reports called ""Stormwater Risk Management- Construction SWPPP Field Inspection Report."" The report includes general information and summarizes the number of findings, the severity of these findings, calculations of how the findings are scored, and the percentage of the corrections made due to the findings. The summary is followed by maps of the construction site with markings of problem areas. The report then progresses into further detail with documentation of each finding including a deadline for correction. The follow-up inspection section indicates if any correction was attempted, any necessary explanation, and the follow up finding severity rating in a similar format. Photos of the site are also present from both initial and follow- up inspections. Continuous implementation of this program will provide substantial contributions to maintaining water quality. In addition, the success of this program provides a model for other project teams seeking to improve stormwater pollution controls and minimize damage to waterways resulting from construction practices. Hensel Phelps received an Environmental Achievement Award in 2008 in recognition of these ongoing benefits from the Mid-Atlantic Environmental Protection Agency. According to the EPA\'s website: ""This award recognizes and rewards projects that have significant sustained, measurable, and replicable environmental results for a clearly defined environmental issue in Delaware, the District of Columbia, Maryland, Pennsylvania, Virginia, or West Virginia; must have reduced pollution and/or protected public health and the environment; has innovative ideas, approaches, techniques, and/or technologies; and demonstrated leadership and outreach to others."""

The proposed REQUIREMENTS are to include the following features in the Transportation Management Plan: Rideshare Matching Assistance, Subsidized Regional Transit Pass ( In lieu of providing 3% with Alternative Fuel Vehicles ), Bike Subsidy and User Groups, Amtrak Subsidy, Guaranteed Ride Home Program. The required SUBMITTALS would require all features listed in the Requirements to be summarized in a narrative and in the form of the LEED letter templates. Possible DESIGN APPROACHES would include working with the local Transportation Management Association or local agency to figure out which options are best suited for the occupants of the building. The following paragraphs further explain of how the requirements will be met. Per the Transportation Management Plan filed with the City of Sacramento, and DPR\'\'s subsequent commitment to participate in and financially support the South Natomas Transportation Management Association (TMA), the following programs and services will be available to all DPR South Natomas employees as well as employees of any subtenant occupying 2480 Natomas Park Drive. Rideshare Matching Assistance The South Natomas TMA supports and uses the regional carpool database, www.1800COMMUTE.org to provide matches for short-term emergencies or long term carpool arrangements. Additionally, we will provide personalized transit trip planning assistance, providing employees a detailed explanation of how to take the bus from home to work, and back again. Prior to DPR relocating to the new South Natomas facility, all occupants will provide their names and nearest cross streets, so that carpool database will generate a personalized transit trip and/or carpool matchlist for each occupant of the building. Subsidized Regional Transit Passes We have a cooperative agreement with Regional Transit to provide photo identification Regional Transit passes to ALL member employees. This is similar to the requirement in SS4.3 to provide alternate fuel vehicles for 3% of the building. By subsidizing the Transit Pass for ALL occupants we feel that we are meeting the intent of the Alternate Transportation credits. This RT pass is valid on Regional Transit light rail and buses for both commute and non-commute trips. YoloBus, Placer County Transit and also accept this pass. Bike Subsidy and Users Group The Bike Users Group is a result of the Bucks for Bikes Program, which provides South Natomas TMA members commute bike purchase subsidies. The South Natomas BUG also provides a voice for cyclists throughout the South Natomas area, advocating safer trails and road conditions, and supporting education for current bicycle commuters and encouragement for fellow cyclists new to commuting by bike. DPR\'\'s bike lockers will complement the employees\'\' participation in our bike-related activities and support bicycle commuting. Amtrak Capitol Corridor Subsidy We offer up to 10 monthly subsidies of $28 each, or the full fare, whichever is lower, to member employees for reimbursement of an Amtrak Capitol Corridor monthly pass or multi-ride ticket. Employees have the option of either transferring to RT # 88/87 (with their Regional Transit pass) to connect to/from the Amtrak station and South Natomas or riding a bike through Discovery Park. (Amtrak has generous facilities for riders to bring bikes on board). Guaranteed Ride Home Program This program provides employees who rideshare two or more days per week and experience a mid-day emergency, or who have to work unexpected overtime, with a free guaranteed ride home using a taxi or rental car service up to 6 times per year." "*NOTE: This CIR has been updated by LEED-NCv2.1 SSc4.1 CIR ruling dated 9/22/2006.* Innovation credits are awarded during the certification process, not through the CIR process. This ruling is provided as guidance about the likely outcome if accomplishments are proven by the certification submittals. The applicant is inquiring about the potential for achieving an innovation point for exemplary performance in alternate transportation by instituting a comprehensive Transportation Management Plan (TMP). The project is likely to be awarded the innovation point as long as: (1) SS Credits 4.1, 4.2, and 4.4 are achieved; (2) the commitment requirements listed below are met; and (3) all commitments are adequately and officially documented. Components of the TMP that were found useful toward achieving this innovation credit include: active use of the regional carpool database; a ""guaranteed ride home"" program for carpoolers; transit trip planning assistance; and subsidizing regional transit passes, Amtrak commuter train tickets, and bicycle purchases for bicycle commuters. Specific details and additional requirements are as follows: Use of the regional carpool database contributes toward exemplary performance, if personalized carpool match lists are provided for all current occupants, as well as for new occupants, and the ""guaranteed ride home"" program is implemented. Official documentation (e.g., a signed letter, or an excerpt from company policy or employee manuals) must show at least a 5-year commitment to these programs. Please note that the practice of subsidizing regional transit passes and Amtrak tickets for occupants IS NOT equivalent in SS Credit 4.3\'s requirement to provide alternate fuel vehicles (contrary to your assertion), even though it displaces vehicle use. However, the transit subsidization program can count toward exemplary performance in relation to SS Credit 4.1, Public Transportation access, if a 5-year (or longer) agreement has been signed and a copy of the agreement is submitted with the LEED application. Transit trip planning also counts toward exemplary performance. State the number of employees that are initially provided personalized trip information and document the policies/procedures that ensure the same service for new employees. Bicycle locker installation is standard practice for SS Credit 4.2. Bike purchase subsidies for bike commuters contribute toward exemplary performance, if a commitment for at least 5 years or 50 bicycles (whichever comes first) is shown via LEED application submittals."

Based on this model and the definition of \'Process Load\' in ASHRAE Standard 90.1-99 (""energy consumed in support of a manufacturing, industrial or commercial process other than conditioning spaces and maintaining comfort and amenities for the occupants of a building""), it is our interpretation that the energy required to power and cool the data center electronics is not included in the baseline energy calculation under the Energy & Atmosphere credit category. (Ref: CIR 4/11/2003 and Ruling 5/5/2003). This leads us to believe that an appropriate venue for credit contribution associated with data center energy reduction initiatives is in the Innovation & Design category. With the rise in bandwidth requirements, optical fiber versus copper has significant energy savings advantages. Energy savings associated with power and cooling of a 10Gbyte/s optical network vs. 10G copper network can range from 75-85% depending on port count. Further, innovative high fiber count pre-terminated optical solutions vs. traditional patch-cord solutions reduce cabling congestion and optimize air flow in the server racks and raceways further reducing cooling energy requirements. Will Innovation & Design credits be considered for the following? 1. Installed cabling infrastructure that provides improved energy efficiency over another. 2. A Pre-Terminated high fiber count optical solution vs. Patch-Cord optical solution." "The applicant is requesting confirmation whether the installation of more efficient network components (i.e., high fiber count pre-terminated optical connections) in data centers may be considered for an innovation in design credit.

Growing plants for market in this manner requires four and a half times less water daily, and requires up to thirty percent less growing time when compared to traditional methods using overhead irrigation. The estimated water savings for the 400 plants used on site, with an average growing period of a year, was almost 70,000 gallons. The Gro-Eco system uses raised beds that are built and covered with weed cloth. Pockets are then dug in the beds to accommodate nursery pots of various sizes - only the upper third of each pot extends above the top of the bed. Irrigation drip tape runs down each row of plants along the tops of the containers, while another drip tube, buried under the cloth in the center of the bed, helps keep the roots cool. Moderating the temperature of the roots improves the health of the plants and further reduces the amount of water needed. Auxiliary benefits of such a system include: thirty to forty percent less chemical use and drastically reduced runoff, elimination of retention ponds and nitrogen leaching, less need for fungicide due to the elimination of excess moisture on leaves, lower energy costs, and less invasive site design due to the flexibility in drainage topography. For more information on the Gro-Eco process, please view the Florida Agriculture video produced for the 2007 Environmental Leadership Award. http://www.florida-agriculture.com/news/agen_fraleighnursery.htm The requirements for this credit would be to document all plants obtained from Gro-Eco for use on the Eco-Office project, and to provide evidence of the estimated water savings being claimed."

The intent of that credit is to demonstrate innovative performance by enhancing the quality of life for campus occupants while reducing vehicular traffic out of campus. CREDIT REQUIREMENTS: The requirements appear very specific and include requirements to incorporate a comprehensive design for a centralized facility to house a cafeteria, gym, travel agency, credit union, printing/publishing services as well as laundry services. While our project includes many of these specific items, a cafeteria, a wellness suite, and potential for travel planning and purchase in the computer lab, it would be redundant for our facility to provide other services provided elsewhere on campus, such as laundry facilities and gymnasium. The Student Center has been designed with the intent to enhance the quality of campus life, build community between students, faculty, staff and the community, and bring a large number of facilities and services under one roof. Prior to designing this building, when interviewed, students complained that there was nothing to do outside of classes and they wanted healthier food choices. The New Student Center was designed to minimize the need for students (as well as visitors, faculty and staff, during office hours) to leave campus to go to Easton Mall and other places to obtain the described services. In addition to the items listed above, the building will provide a convenience store, a bookstore, study and social lounges, a campus radio station, a computer lab for personal usage, small, medium and large meeting rooms s available for on-campus group meetings, and the project encloses the pedestrian access to the gym, basketball courts, dance area, showers and lockers in an adjoining facility less than 200 feet away. PROJECT APPROACH TO ACHIEVING CREDIT: In providing the documentation for this innovative design credit, we propose to: - Estimate the reduction of vehicular usage by providing these additional services to the campus and surrounding community by the addition of this new building. - Calculate the environmental benefits and the reduction of impacts in comparison to a conventional campus complex including how many people visit each facility/day and the subsequent reduction in CO2. - In addition, we will provide an itemized list of other facilities and services currently available on campus within walking distance of the new student center."

The project team is proposing to demonstrate that the centralized facility will reduce the CO2 associated with student/visitor commuting. While the incorporation of the various services into the centralized facility is commendable, it is common practice for educational institutes to incorporate a variety of services within a centralized facility like this, to serve the needs of the student population on campus.

Our project is a large destination resort which includes 18 service and passenger elevators: 14 high-rise and 4 low-rise. Compared to conventional traction (high-rise) and hydraulic (low-rise) elevators typically specified for this type of project (based on a recent similar-scale resort project located near our project), the elevators for the project will have these benefits:  Annual process energy cost will be reduced by 65% compared to that of conventional elevators: $8,400/yr vs $23,900/yr.  The coated steel belts used in the proposed fourteen high-rise elevators have a lifespan twice that of conventional hoist-rope assemblies. This means that, for the fourteen high-rise elevators, the owner will need to replace 12,600 feet of steel belts half as often as for conventional elevators.  The proposed fourteen high-rise elevators do not require lubrication because they do not have hoist ropes and machine rooms. This will eliminate, for each elevator, 1 gallon of petroleum-based and 3 -4 gallons of synthetic-base oil each year.  Compared to the conventional approach of four low-rise hydraulic elevators, the proposed four traction elevators will use no hydraulic fluid, for a savings of 320 gallons. Elevator hydraulic fluid is typically a hydrocarbon. From BuildingGreen.com: ""Leaking hydraulic oil, like all spilled oil, poses environmental risks in the form of soil and water contamination. Cleanup of hydraulic-oil-contaminated soils is a difficult and costly task..""  All these elevators do not require a machine room. If we were including conventional elevators in our project, these machine rooms would total 3,200 sf. This additional space would require additional construction, including structural steel and framing, concrete, exterior and interior finishes, roofing, and electrical systems, for an added project cost of $1,120,000.

The following are requirements for ""Innovative Performance"" and description, how the proposed design\'s approach would meet these requirements: 1. Quantitative performance improvements. Location of the well in the middle of the playfields minimizes the irrigation piping. Ground water aquifer allows continuous, uninterrupted supply of filtered water. In the pumphouse adjacent to the well there is on-demand irrigation controller and AC Tech Variable Frequency Speed motor drive which controls well pumps. Both of these controllers allow for easy interface between the ground water well supply and the irrigation demand read by the irrigation controller\'s soil moisture sensors. 2.

However, we are looking to use approximately 10% of normal, non-blended cement (300 cy out of a total of 3,000 cy)due to coordination and timing issues. If we then use approximately 90% blended cement, would we still be eligible for the innovation credit?" "To achieve an environmental benefit, it is critical that fly-ash REPLACE cement content, not just be added as a filler. Adding fly-ash to a concrete mix without reducing cement content has only limited advantages to the environment. It is unclear from the question whether the project is actually off-setting cement use. The Credit Ruling Committee has suggested that a 40% REPLACEMENT of cement with fly-ash would qualify for an innovation credit. Lower levels of fly-ash use are more typical, and would not be considered innovative enough to warrant an innovation point. Note that there are many complexities of fly-ash use with respect to concrete strength requirements that factor into the discussion of what constitutes an innovation. Regardless of the percent used, fly-ash content would count toward MR Credit 4; Recycled Content Materials.\n\nModification Note as of July 1st, 2012: The applicability of this LEED Interpretation has been modified to indicate that it is applicable to LEED 2009 projects. However, USGBC and GBCI will be phasing this Innovation strategy out. While this strategy is acceptable for LEED 2009 it will not be acceptable for LEED 2012 because the environmental benefit(s) of replacing cement with alternative cementitious material will be captured in available credits.

Instead of the conventional chlorine system, we are using an ozone system to treat the water. The Ozone system has the following advantage: - Destroys bacteria, mold and mildew - Eliminates spores, yeasts, fungus and inactivates viruses - Aids the removal of minerals such as iron and manganese - Water is softer and has neutral pH - Leaves no unpleasant chemical or smell, no chloramines build-up, the by-products of ozone are heat and pure oxygen - No irritation to the eyes, nasal passages or throat - Will not cause dry skin, bleached hair or faded swimwear - Reduce chlorine consumption to a minimum, saving money on maintenance, and avoid storing such toxic chemical on site. To summarize, the system reduces the use of chlorine greatly (50-75% depending on splash limit). Unlike chlorine, ozone leaves no unpleasant odors or residual chemicals in the pool and spas. It eliminates the problems of red and irritated eyes, dry skin, faded swim wear and other problems associated with chlorine. We believe that this system has significantly increased the indoor environment quality of the project, especially when the pool and spas are frequently used being in a sports facility instead of a private residence. And a large amount of occupants will be benefited. Therefore, we would like to use this for one of our Innovation and Design Credits. Please advice on the feasibility." "The proposed strategy, if incorporated properly, may warrant an innovation credit. The use of an ozonation system that is properly sized and integrated into the swimming pool treatment system will allow ozone to act as the primary oxidizer and disinfectant. Since there is no uniform standard which has been established for ozonation of pools, ozone design criteria for disinfection in the United States is based primarily around US EPA Drinking Water Guidelines. Dose rate values between .4 mg-O3/l are normally cited and .8 mg-O3/l is commonly used. While LEED encourage approaches that reduce the use of toxic chemicals, additional information is required to provide a complete assessment of credit achievement in this case. Please describe limited reduction of chlorine (e.g., state if regulations require a minimum level of chlorine), and provide detailed explanation and proof of substantial environmental benefits (quantified as much as possible). See IDc1.1 CIR review dated 5/21/2003 for further guidance on this issue including appropriate documentation. Applicable Internationally.

In particular, bamboo is a rapidly renewable material and has been used widely in gyms in Europe, but the client was not very comfortable of incorporating the material. In order to convince the client/ users to use bamboo flooring in lieu of hardwood for sports flooring, we installed a demonstration racquetball court. Users are provided with information of the new product and can try playing on the bamboo flooring. At the end, although bamboo is not used for the basketball courts and racquetball courts, they are used in the aerobics area and other common circulation space. Along the line of USGBC\'s policy of ""no work, no point"", we feel that this is a significant effort by the design team to introduce unfamiliar materials to the client. And we would qualify for an Innovation and Design Credit. Please advice on the feasibility of the credit." "This does not meet criteria for an innovation point. However, if the demonstration component is extended to other facets of the building, it may be appropriate to pursue an innovation credit for whole building demonstration. Please see IDc1.1 CIR dated 9/24/2001 for a complete outline of associated requirements. Your assertion that USGBC has a policy of ""no work, no point"" is not accurate; USGBC has no official policy in this regard.

Due to the site and security constraints, we are unable to incorporate windows in the space. However, the design team feels strongly about the importance of natural light, especially in a sports facility, where users are exercising and relaxing. Therefore, in the design, we introduce 4 clerestories, designed with internal reflectors, along the sports facility to bring in natural light. As a result, the daylight factors of the major interior spaces are as follows: Natatorium: 7% Indoor track: 29% Indoor basketball court: 14% This is remarkable results for an underground facility. the clerestories also serves as fresh air intakes for the mechanical systems, therefore reducing the need of constructing a separate aerial way. We strongly believe that this will be qualified for an Innovation and Design Credit." "The incorporation of daylight is a strategy which is addressed in EQc8 and is a design option in most building types, including underground facilities. It appears that the design strategy outlined will meet the criteria for EQc8.1 for natural light in 75% of regularly occupied spaces and does not warrant a separate credit for innovation.
