The CIR appears to be written for new construction and for sale unit properties (such as condos).\nThe 2004 LEED NC CIR states that multi-unit residential buildings must meet the requirements for commercial buildings (covering common area, owner controlled areas of the building), and the following for the residential, tenant controlled areas:\nItem #1: Educate the residents on the green cleaning concepts and products via discussion and written materials upon move-in and periodically thereafter.\nItem #2: Provide an estimated six-month supply of green cleaning products to residents, as well\nas information on how to easily purchase refills and/or replacements.\nAssume that a Multi-Family Residential Apartment (Rental) Property complies with the following:\n1.\nThe property that is applying for LEED EB certification meets all the requirements for LEED EB Green Cleaning credits for common spaces/owner controlled spaces including the cleaning policy and plan, products purchased and used, equipment purchased and used, and also follows the same green cleaning procedures whenever they have access to residential apartment units (including during all " "The project has proposed an alternative compliance path for 2009 Existing Buildings: Operations & Maintenance projects that include multi-family residential units for IEQ Prerequisite 3: Green Cleaning Policy, IEQ Credit 3.1: Green Cleaning High Performance Cleaning program, and IEQ Credit 3.3: Green Cleaning- Purchase of Sustainable Cleaning Products and Materials using Innovation in Design credit requirements outlined in Formal Inquiry dated 04/08/2004 ID #766 for multi-family New Construction projects. The proposed approach is not acceptable. \n\nFor IEQ Prerequisite 3: Green Cleaning Policy and IEQc3.1: Green Cleaning-High-Performance Cleaning Program, the green cleaning policy and program includes resident areas. Additional steps should be taken to educate the residents on the green cleaning concepts and recommended products via discussion and written materials upon move-in and periodically thereafter.

"None" "None" "X" "LEED Interpretation" "10141" "2011-11-01" "Existing Buildings" "EQc3.3 - Green cleaning - purchase of sustainable cleaning products and materials" "The project team proposes to use a environmentally preferable cleaning solution, a handheld ionized tap water system, to eliminate or significantly reduce the amount of chemicals used within the project building. \n The ionized water system works as follows: \n\n 1.When the spray bottle trigger is pressed, the water flows through a water cell that applies a slight electrical charge to the tap water.\n 2.The charged water passes through an ion exchange membrane, where the ionized water is separated into an oxygenated mixture of positively and negatively electrically charged nano-bubbles.\n 3.When applied directly to a surface, the ionized water helps break apart and lift the dirt from the surface like a magnet, enabling it to be wiped away.\n 4.Before the water exits the nozzle, a slight electric field is applied, allowing the water to carry a low-level electric field to the surface where the germs may be living. When used as directed with tap water in the majority of municipalities, this low-level electric field can kill more than 99.9 percent of harmful germs.\n\n Using an ionized water cleaning system would no longer require purchase of many green cleaning chemicals; therefore, the project team has developed a new approach to documenting IEQc3.3. Rather than documenting that 30 percent of the products purchased meet the LEED sustainable cleaning criteria (by cost), the project team proposes to document the cleaning methods used during each cleaning shift. After each shift, the housekeeping personnel will document the cleaning methods and chemicals (or tap water if using the electrolyzed water system) used. Sustainable methods and chemicals that meet the LEED requirements for this alternative compliance approach will include either the use of chemicals that meet existing IEQc3.3 requirements or the use of ionized tap water.\n\n An alternative compliance table will be created by the project team to account for criteria (with regard to performance vs. purchases) in order to demonstrate compliance with the SSc3.3 requirements. " """The project team seeks allowance to satisfy the credit requirements through the use of ionized tap water in lieu of chemical cleaning solutions. This is an acceptable approach if the following criteria are met:\n •Manufacturer’s documentation of third-party performance testing is included with the credit submittal documentation. The testing should demonstrate performance comparable to Green Seal, Environmental Choice, or another standard equivalent to or more stringent than those required in IEQc3.3: Green Cleaning—Purchase of Sustainable Cleaning Products and Materials. \n •If the device is marketed and used for antimicrobial cleaning, manufacturer’s testing must demonstrate antimicrobial performance comparable to EPA’s Office of Pollution Prevention and Toxics (OPPT) and Design for the Environment (DfE) requirements as appropriate for use patterns and marketing claims.\n •A custodial effectiveness assessment is performed as outlined in IEQc3.2: Green Cleaning—Custodial Effectiveness Assessment. \n •The typical performance metric (percentage of purchases based on cost) for evaluating compliance with this credit will not apply. The project team may show compliance with one of the following:\n a) Showing, based on one year of historic cleaning chemical costs, that use of ionized tap water during the performance period has reduced the purchase of chemical cleaning and material products by at least 30%. Any changes in occupancy or other factors that vary between the baseline year and the performance period that affect the need for cleaning products must be accounted for in the analysis.\n b. Tracking the total cost of all cleaning and material products purchased during the performance period, plus the amortized cost for the ionized water cleaning system (amortized over 12 months). \n c) Tracking the total volume of cleaning and material products and ionized water used during the performance period and showing that 30% meets the existing IEQc3.3 criteria or is ionized tap water.

One reason carpet tile is not accepted is because it cannot be cleaned underneath and therefore does not meet the performance of mechanical systems (such as grates/grilles), or roll-out mats. Carpet tile is a highly desired material for walk off areas due to its ease of maintenance as compared to mechanical systems, avoidance of trip hazards associated with roll-out mats, and numerous other factors. The ability to clean underneath carpet tile is not necessary. Carpet tile creates a sealed floor where dirt and moisture do not penetrate the seams. Though not specifically required by the rating system, the reference guide provides suggestions for optimal performance attributes for entryway systems. The carpet tile product we are suggesting meets the performance-related attributes as follows: \nCapture particles & prevent interior contamination- the carpet tile product is specifically designed to withstand heavy traffic at entranceways. Captures and hides soil, requires minimal maintenance and helps prevent slips and falls. Extend 10 feet: the carpet tile will extend 15\' into the interior from the exterior entrance and 40\' in left-right directions along the building lobby. Solid backings & appropriate for climate- the carpet tile backing is stable even under extreme changes in temperature and humidity. It will not move, create gaps, or curl up over time. High-void-volume & high fiber height- the carpet tile is produced with needlepunch hair-like face fibers with pile height of 0.165 in. Electrostatic propensity- the electrostatic propensity level is less than 2.5 kV. Weekly cleaning - the walk-off system will be maintained by the in-house school maintenance staff. The tiles are vacuumed daily and spot cleaned with appropriate environmentally-preferable cleaning products as needed. If an individual tile is deemed to be damaged beyond repair, it is simply removed and immediately replaced with a new identical tile. \n \nHow can we demonstrate that carpet tile is an equally performing or better solution for entryway systems?" "The applicant is requesting confirmation that carpet tiles may be used as acceptable entryway systems. Yes, carpet tiles with similar attributes to the product described are acceptable entryway systems.Conventional carpet is not acceptable, the carpet tile must be specifically designed for entryway system or similar use, have performance attributes equivalent to other acceptable entryway systems, and must be regularly maintained.

The warehouse space will be used for storage of goods and materials that will be transported to an adjacent facility (within 1/8 of a mile) for use in product manufacturing. The employees of the warehouse facility will spend a majority of their day within the office space except for the occasional need to go out into the warehouse space to receive and stock incoming shipments, or transition of these goods and materials to the adjacent facility. The layout of the warehouse space will consist of long rows of aligned storage racks and shelving - with intermediate aisles and end aisles that would be parallel with the exterior walls of the building. One side of the building will have freight car (rail) access as well as tractor-trailer access with overhead doors. As such, is the entire warehouse space considered ""regularly occupied"" space? If so, would we be required to provide ""pollutant control"" system for fork trucks moving goods and materials in and out of the freight cars and tractor-trailers? If so, would permanently installed grill or grate systems (for the fork trucks) aligned with these transition points fulfill the requirements of this credit? If the warehouse space is not considered ""regularly occupied"" space would we only be required to meet the needs of the office space? Please provide some guidance on a strategy that would be consistent with the intent of this credit." "At a minimum, you should provide entryway grates/grilles at all regular entry points for the building users, covering both the warehouse and office space. The same entryway system requirement would not apply directly to the fork truck operations; however, to be consistent with the credit intent, you should describe the measures included in the design to minimize pollutant entry into the building from these vehicles.\n\n **Updated on October 1, 2013 to clarify the entryway system requirement and to align the ruling with LI 5177.\n The project team is requesting clarification on the entryway system requirements for a warehouse space. The exterior entrances to loading docks and garages are not required to have entryway systems. Regularly used entrances from these areas into adjacent spaces in the building (typically office areas of the building) must have entryway systems."

In order to fulfill the intent of this credit, all copy and maintenance rooms have hard ceilings and self-closing doors, and will be exhausted sufficiently to create negative pressure. Air filtration media will provide a MERV rating of 13. Walk-off mats will be installed at all regular entry points into the building, and a cleaning service will be contracted to replace the dirty mats and clean them off-site. We are asking whether the design and cleaning program of our 16 loading bays will comply with the requirements of this credit. To prevent contaminants from entering the building, our loading bay area has been designed with a continuous pit and vertical storing system for the loading docks. We use this design because it far exceeds traditional pit set-up both for cleanliness and thermal efficiency. Such a system differs from the norm for three reasons relevant to this credit: 1) The dock doors close all the way to the dock floor when not in use, preventing dirt and debris from entering. A tight seal is made between floor and door, further hindering pollutant entry. 2) The continuous pit - a space approximately 4ft deep between warehouse floor and bay door which runs the length of the dock bay area and is 18 inches lower than the warehouse floor - serves as a catch basin for dust or particulates coming into the building and allows for easy routine cleaning. 3) Vertical storing dock leveler design further supports easy routine pit cleaning and wash downs by remaining out of the way when not in use. We believe that the innovative design of our loading bays - coupled with the planned stringent cleaning program of this food-grade manufacturing plant - meets the intent of credit EQ 5. Please advise." "The project team is asking whether providing a continuous pit in the loading dock would meet the entryway system requirements of the credit. As described in this CIR, the loading dock entryways into the warehouse do not qualify as regular entry points for building users and thus do not need to be provided with entryway systems. The strategies employed by the project team to reduce indoor chemical and pollutant sources are commendable and encouraged but they are not required by this credit.\n\n **Update October 1, 2013: Applicable credits have been updated."
