Stanford designs, constructs, and operates high-performance campus buildings. Accolades for design and operation abound, including LEED Platinum certifications for both New Construction and Existing Building projects on campus.

Yang & Yamazaki Environment & Energy Building (2008)
The Jerry Yang & Akiko Yamazaki Environment + Energy Building (Y2E2), the first large-scale, mixed-use, high-performance building at Stanford houses cross-disciplinary teams and programs with teaching and research focused on sustainability. Y2E2 continues to serve as a learning tool for both building occupants and the campus community and recently earned a LEED-EBOM (Existing Building: Operations & Maintenance) Platinum certification, the highest rating awarded by the United States Green Building Council (USGBC). As the first LEED-EBOM certification on campus, the Y2E2 project allowed Stanford to evaluate the benefits of the certification process and further investigate opportunities in design and operation of high-performance buildings.
The project earned 82 points, exceeding the 80 point threshold required for the Platinum rating. Highlights included earning all 15 points available in the alternative transportation credit, plus a bonus point due to its regional significance, earning 14 points in the energy efficiency credit demonstrating documented energy consumption 37% better than the national median of comparable buildings, and earning all 5 available points for the performance of indoor plumbing fixtures.
Significant sustainability features of the 166,000 square-foot building include:
- A high-performance envelope (roof, walls, windows, sunshades and light shelves) to reduce heating and cooling loads.
- Natural ventilation via internal atria, windows, and vents with efficient active beams for mechanical cooling when needed.
- Three solar photovoltaic demonstration installations to 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.
