The Jerry Yang and Akiko Yamazaki Environment + Energy Building (Y2E2), the first large-scale, mixed-use, high-performance building at Stanford, remains a landmark structure. It houses cross-disciplinary research teams and programs with teaching focused on sustainability. The building itself continues to serve as a learning tool for both building occupants and the campus community.

The 166,500-square-foot building uses 42 percent less energy than a traditional building of comparable size and 90 percent less total water than one with traditional fixtures and systems. Significant portions do not require air conditioning, and much of the building relies on natural light during the day.

Sustainability features include:

• A high-performance envelope (roof, walls, windows, sunshades and light shelves) reduced heating and cooling loads.
• Natural ventilation via internal atria, windows, and vents. Efficient active beams for mechanical cooling when needed.
• Three solar photovoltaic demonstration installations offset energy use.
• Water conservation systems, including waterless urinals and dual-flush toilets; recycled water from Stanford’s Central Energy Facility is used in toilets, urinals, and for some lab processes.
• Extensive use of recycled materials and sustainable products, such as bamboo. Exposed concrete floors significantly reduced carpet use and saved tons of raw materials.

Most recently, the formal process began to seek LEED-EBOM (Existing Building: Operations & Maintenance) certification. The Y2E2 LEED-EBOM certification project is a donor-funded effort initiated by Stanford Woods Institute faculty and coordinated through Stanford’s Office of Sustainability. As the first LEED-EBOM certification at SEQ and on campus, the Y2E2 project will allow Stanford to evaluate the benefits of the certification process and further investigate opportunities in the design and operation of high-performance buildings.

The San Francisco Business Times named Environment + Energy the Best Green Building in the Bay Area in March 2008.

The Knight Management Center (KMC), an eight-building, 360,000 square-foot complex for the Graduate School of Business, earned a LEED-NC Platinum® rating from the U.S. Green Building Council – the organization’s highest certification level. The project received 60 points, far above the 52-point threshold for Platinum. “ The design of the new facility underscores what is taught in many GSB electives, such as Environmental Entrepreneurship and Environmental Science for Managers and Policy Makers, as well as in core classes covering sustainability across business functions and the MBA/MS Environment and Resources joint degree program.

The building contains a variety of energy efficiency features, including:

• Rooftop PV panels that generate 12.5 percent of KMC’s electricity needs;
• Extensive use of natural daylight and automatic light sensors to reduce artificial lighting when not necessary;
• Rainwater capture, storage, and reuse for onsite irrigation;
• Chilled beams and night flushing provide efficient cooling;
• Recycled content in 25 percent of building materials and more than 98 percent of waste from building construction diverted from landfill.

The Silicon Valley Business Journal named Knight Management Center Green Project of the Year in 2010.

A central theme of openness characterizes the Law School’s William H. Neukom Building. The 65,000-square-foot space features conference rooms, faculty offices, open areas for group work, and the Mills Legal Clinic within four three-story wings connected by dramatic glasswalled pedestrian bridges. Sustainability strategies such as maximized use of natural light, automated control systems, natural ventilation, ceiling fans, high-efficiency glazing, and trellis shading contribute to energy use projected to be 30% less than code. The building’s exterior features rainwater harvesting and native plant species. The Neukom Building, a LEED-NC Gold-equivalent project, exemplifies high-performance design and construction principles now common practice on campus.

The School of Engineering’s new Jen-Hsun Huang Engineering Center (HEC) follows the example of its predecessor, the Jerry Yang and Akiko Yamazaki Environment and Energy Building (Y2E2), and epitomizes high-performance design and construction. Performance models suggest that aggregate energy use, including plug loads, will be 42% less than those of standard buildings. HEC features an enhanced building envelope with high-performance windows, makes extensive use of daylight and photocell technology, employs a combination of natural ventilation and active chilled beams, includes rapidly renewable materials in architectural woodwork and furniture, and uses the university’s recycled water system to flush toilets and urinals. A 30kW DC solar photovoltaic installation will meet some of the building’s electricity demand. To complete the HEC auditorium, 316 seats were salvaged from the demolition of Kresge Auditorium, refurbished, and redeployed.

The Center for Nanoscale Science and Engineering (Nano) houses the Edward L. Ginzton independent laboratory as well as the offices of the Department of Applied Physics. Research activities in the Nano Center span a broad range of areas from photonics and quantum engineering to single-molecule biophysics. User facilities within the building feature some of the most advanced nanoscale patterning and characterization equipment available (complementing the nearby Stanford Nanocharacterization Lab and Stanford Nanofabrication Facility), largely in underground installations to provide the stringent control of vibration, light and cleanliness that is essential for nanoscale research

Performance models suggest aggregate energy use in Nano, including plug loads, remains 37% less than standard buildings. Like its predecessors in SEQ, Nano makes use of day-lighting and photocell technology, employs a combination of natural ventilation and active chilled beams, and uses the university’s recycled-water system to flush toilets and urinals. In addition, a 30kW DC solar photovoltaic installation will meet some of the building’s electricity demand.

The Lorry I. Lokey Stem Cell Research Building (SIM1), a 200,000-GSF School of Medicine building, has a basement vivarium and three above-grade floors with research labs and support facilities. Stanford established targets comparable to a LEED-NC Silver rating for the project. Significant sustainability features include:

• Segregated laboratory and other occupancy types to increase HVAC operating efficiency
• Sloped ceilings in labs for increased daylighting and solar photo cells for lighting control
• Reusable animal cages throughout the vivarium, eliminating cage wash equipment and avoiding the use of approximately 9 million gallons of water annually
• Elimination of relative humidity controls from air-handling equipment and the vivarium rooms due to the local climate

Fully occupied in fall 2010, SIM1 became the nation’s largest center dedicated to stem cell research. An example of high-performance building in the face of highly technical programmatic requirements, SIM1 serves as a national model for laboratory design and construction.

The Li Ka Shing Center for Learning and Knowledge (LKSC), a 118,000-GSF School of Medicine building, includes medical simulation and virtual reality environments to advance teaching, learning, and knowledge management. Four above-grade floors house a conference center, classrooms, and study areas. The basement features the Center for Immersive and Simulation Based Learning.

Prominent sustainability features include:

• Recycled water for flushing toilets and urinals
• High-performance glazing, sun shades, and a reflective roofing surface
• HVAC system with chilled beams and displacement ventilation
• Diversion of 95% of construction and demolition debris from landfill

The Li Ka Shing Center for Learning and Knowledge has already become a hub for education, training, conferences, and interdisciplinary programs for the School of Medicine.

The Carnegie Institution’s Global Ecology Research Center is an extremely low-energy laboratory and office building that emits 72 percent less carbon and uses 33 percent less water than a comparable standard building

The center features an evaporative downdraft cooling tower, an exterior made from salvaged wine-cask redwood, no-irrigation landscaping, dual-flush toilets and low-flow faucets. The design also furthers academic work: a "night sky" radiant cooling system demonstrates the principles of radiant heat loss to deep space–principles that the center’s researchers are investigating.

The American Institute of Architects Committee on the Environment named the Global Ecology Research Center one of its Top Ten Green Projects in 2007.
