Refinements in Materials & Resources
We are in the midst of a really exciting time for LEED and USGBC. LEED v4 will be balloted in June of this year and in the time we have leading up to that point, USGBC is taking every moment to make sure the system is fully usable and the program has been thoroughly tested.
USGBC Members in Support of LEED
"LEED certification in buildings benefits the environment and the bottom line. LEED certified buildings in San Francisco and around the country are saving money and increasing their property value while reducing their overall environmental footprint,” says Melanie Nutter, Director of the San Francisco Department of the Environment. “Since buildings contribute 53% of greenhouse gas emissions in San Francisco, it is essential that we address inefficiencies in the built environment.

This development was an infill project with a density of 28.6 units per acre, constructed in the downtown Palo Alto area and within walking distance of public transportation
Congratulations to Clarum Homes, Cambridge Plaza as the recipient of the 2012 LEED for Homes award for Outstanding production builder.
Cambridge Plaza is a four-unit detached, three-story townhome project constructed by Clarum Homes on a concrete podium over parking and a 1,080-square-foot retail space. The project achieved LEED for Homes Platinum certification, using strategies including energy efficiency and sustainable building materials, inspiring modern and cosmopolitan sophistication.
This development was an infill project with a density of 28.6 units per acre, constructed in the downtown Palo Alto area and within walking distance of public transportation (including CalTrain and bus stops), Stanford University, shopping, restaurants, various businesses, a farmers market, neighborhood parks, and Stanford Hospital.
The exterior design included all drought-tolerant plant materials, no conventional turf, and reduced irrigation demand. We minimized the heat island effect by installing 80% of the hardscape using a light-colored, high-albedo paver with a solar reflectance index (SRI) of 39%. Each home features a 2.0-kW photovoltaic system and a thermal solar hot water system using an 80-gallon pre-heat storage tank and a G.E. GeoSpring electric heat pump back-up water heater.
The parking garage features several unusual innovations such as individual parking spaces with car stackers, electric car chargers at each parking space connected to the individual photovoltaic system, and individual storage rooms for each unit.
The project earned exceptional energy performance of 48.7% above Title-24 using high-efficiency framing including 12-inch structural insulated panels (SIPs) for roofing, pre-cut framing packages, open-web floor trusses, stud spacing of 24 inches off center, and engineered wood. We also used blown-in fiberglass loose fill insulation, providing a value of R-21; Marvin Integrity fiberglass windows; exterior insulation (Outsulation) over solid sheathing; largely LED lighting that is 100% high-efficiency; sustainable flooring products; and low- VOC paints and adhesives.
Our commitment to energy efficiency started with HVAC design, using a Zehnder Heat Recovery Ventilator (HRV) in conjunction with a Fujitsu mini-split heat pump system for both heating and cooling. Both of these systems are tied directly into the unit's individual photovoltaic system. The HRV brings in fresh air through a MERV 13 filter 24 hours per day every day and is capable of heating this fresh air using the heat from the exhausted air. Each home has energy-efficient appliances with ENERGY STAR ratings, including induction cooktops.
Water efficiency was achieved by using a structured plumbing system with recirculating pump and high-efficiency plumbing fixtures and fittings, such as dual-flush toilets, lavatory faucets, and showers that meet EPA WaterSense specifications. An EPA WaterSense certified professional designed the irrigation system using drip irrigation over 90% of the planting beds, a timer for each watering zone, pressure-regulating devices, and a moisture sensor controller.
LEED BD+C: New Construction v2.2
KZF Design Headquarters
Cincinnati, OH 45202
LEED Gold 2010
The studio environment encourages creativity and staff recruitment and retention.
This 1915, three-story reinforced concrete structure is the award-winning headquarters of KZF Design. The LEED Gold and ENERGY STAR® certified building is a showplace of innovative workplace and sustainable design for this architectural, engineering, interior design and urban planning firm.
Originally the home of the US Shoe Machinery Company, the entire 36,000 SF building has been renovated and adapted into cutting-edge Architectural and Engineering design studios. Bathed in natural light, the voluminous spaces house the firm’s employees in a contemporary, open-office concept. The studio environment encourages creativity and staff recruitment and retention.
The structure is an early example of reinforced concrete construction and was designed to accommodate a future fourth floor. The new design blends the classic terracotta north facade with new accessible entrances on the south facade. KZF Design occupies all three of the floors.
While the original structure of the building remains, the HVAC, plumbing and electrical systems as well as thermal envelope of the building are state-of-the-art. A contemporary entrance and circulation elements provide visual clues to the new and exciting spaces contained within the historic shell. At the street-level, a high-visibility retail space helps enliven and animate the entire block. Secured parking is recessed below the street level.
A dormant skylight atop the three-story structure was renovated with the addition of energy-efficient glazing, increasing the available natural daylight to studio spaces. Work also included installation of new technology connections, A/V equipment, telecommunications systems, closed-circuit camera monitoring systems and access controls for 24/7 building security.
This building received a 2011 Honorable Mention Award for Built Work from the Cincinnati Chapter of the American Institute of Architects. Juror Scott Duncan, Design Director for SOM New York, presented the award and stated that the jury commented, "We would all like to work there."

LEED BD+C: New Construction v2009
LEED Gold 2011
Considering the heavy energy consumption of data centers, utilities usage became a major focus in trying to minimize BendBroadband’s environmental footprint, while also reducing long-term operational costs.
To support an expanded business services portfolio designed to remain competitive in a world of ever-increasing IT business needs, BendBroadband required a new facility. The new data center, The Vault, was constructed in an existing shell space of a pre-engineered building structure, complemented by block wall construction and a fully developed site plan.
The scope of construction focused on taking an existing, 30,002-square-foot warehouse structure, and while completing significant site and structural upgrades, building out the interiors to create a new Tier III certified data center. Tier III classification is the second-highest of a four-tier certification by the Uptime Institute, which has established globally-accepted reliability guidelines for data centers. The building encompasses more than 23,000 square feet, including data halls, a network operations center, administrative space, functional space (including electrical and operations), and common areas (such as restrooms and utility support). This facility supports BendBroadband’s new services, including equipment co-location; hosted and on-demand storage, cloud computing, and managed services offerings; virtual leased IT environments; and application and disaster recovery hosting. The facility primarily maintains a “B” occupancy rating. Construction had to be completed within six months, introducing a number of unique challenges related to team composition, weather, and commissioning.
Design priorities included security; LEED certification; local and regional participation in design, construction, products, and labor; energy efficiency; and environmentally-friendly construction materials. The building features 27% recycled and 30% locally-sourced building materials. Energy efficiency measures include a 152-kilowatt photovoltaic array that offsets energy, particularly during peak hours, and daylight-sensitive lighting controls and LED lighting. All power consumed that is not produced by the photovoltaics is offset by renewable (hydro- and wind power) energy credits purchased through Pacific Power’s Blue Sky program. Whereas traditional data centers use uninterruptable power supplies (UPS) with battery storage, BendBroadband installed UPS units with no batteries utilizing flywheel technology, and therefore there is no battery-contained corrosive content in the building. Given the building’s location in the dry, high desert of Oregon, water efficiency was an important priority, exemplified by the project’s use of xeriscaping to eliminate the need for irrigation.
Committed to reducing data center dependency on the rarest regional resource – water – the project team felt it could be most innovative in cooling the data hall. Since cooling is the most expensive controllable cost in a co-location data center, this area also offered the single greatest opportunity to reduce ongoing operational costs and control power consumption. Alternatives to traditional evaporative cooling were considered and an air-to-air heat exchanger technology was ultimately selected. This technology significantly reduces water use, only needed in extreme conditions through the redundant direct expansion (DX) cooling backup module.
Much of the site was disturbed by new utilities, equipment areas, and loading dock construction. Pervious paving, vegetative filters, and bioswales were cost-effective solutions to reducing onsite stormwater runoff, an important design element that was heavily challenged by cost limitations and the goal to restore the site as best as possible to its native condition.
BendBroadband's intent to reduce its burden on the municipal water supply and wastewater systems influenced the project in such a way as to specify low-flow toilets and urinals, as well as sensor controlled bathroom and kitchen faucets. The result of these water savings strategies concluded in a 40% overall water reduction compared to a baseline model.
The site is located in the high desert of Central Oregon. Formerly a building used as a tarp and liner manufacturing facility, the building stands one story high on a property zoned for light industrial use and regulated by the City of Bend and the County of Deschutes. It is a pre-engineered metal building sitting on a relatively simple site, making the aspect of adaptive reuse ideal.
LEED BD+C: New Construction v2.2
UC Davis Brewery, Winery and Food
LEED Platinum 2010
Design-build delivery was essential to achieve LEED Platinum performance within a lean construction budget.
The 34,000-square-foot facility, funded entirely by private donations, includes the Teaching and Research Winery and the August A. Busch III Brewing and Food Science Laboratory. It is designed to LEED Platinum building and construction standards — the highest certification granted by the U.S. Green Building Council.
The facility, located near UC Davis’ south entry from Interstate 80, complements the other three buildings of the Robert Mondavi Institute. Construction was completed in 2010. It houses the world’s first LEED Platinum winery, first LEED Platinum brewery and first LEED Platinum food processing pilot plant and milk-processing lab. It is the first LEED Platinum building on the UC Davis campus and only the third built by UC. (The other two are UC Davis’ Tahoe Center for the Environmental Sciences in Incline Village, Nev., and UC Santa Barbara’s Bren Hall.)
Built to accommodate the many teaching and research activities involved with brewing, winemaking and food processing, the building is one of the most complex facilities on campus. Shared by the Department of Viticulture and Enology and the Department of Food Science and Technology, it comprises two attached wings. The north wing houses the Teaching and Research Winery, and the south wing houses the August A. Busch III Brewing and Food Science Laboratory.
“It not only meets the highest environmental design and construction standards, it goes even further to demonstrate how environmentally responsible technologies can be incorporated into the daily operations of food and beverage processing facilities,” said enology professor Roger Boulton, the Stephen Sinclair Scott endowed chair in enology, who specializes in the chemical and biochemical engineering aspects of winemaking.

The UC Davis Wine Brewery and Food Facility is located on the southern end of the UC Davis campus. Because the project is located on a campus, occupants enjoy many amenities within walking distance, as well as access to public transportation, bike storage and charging stations for electric vehicles. With a half acre of restored natural grassland nearby and native and adaptive landscaping, there is a high ratio of open space to development footprint.
