Caltech prioritizes sustainability in building design and construction, complementing building occupants' efforts to minimize the waste and environmental impact associated with their laboratories, housing, offices, and shared spaces.
Built to Be Sustainable
For more than a decade, Caltech has committed to green building principles, and today, more than one-sixth of the campus building space is certified as LEED Gold or better. LEED stands for Leadership in Energy and Environmental Design and is a rating system developed by the U.S. Green Building Council.
The campus now features 13 LEED-certified buildings, up from four in 2011. Caltech LEED certification includes eight buildings rated Gold and four rated Platinum. Since 2008, 827,167 square feet of renovated or new building space has been certified.
Caltech has gone beyond LEED in piloting sustainable laboratory design techniques, transforming historic spaces into cutting-edge laboratories, and reconceiving campus utilities.
The Resnick Sustainability Center, a hub for energy and sustainability research and LEED Platinum recipient, was completed just north of San Pasqual Street on the east side of Wilson Avenue.
Waste, Recycling, and Conservation
Laboratories use significant amounts of energy, supplies, water, chemicals, and materials. Caltech's Green Labs program encourages research groups to assess their environmental impact and institute energy-, water-, and waste-saving practices. The includes a certification option, communications network, and organization of rebates and information related to laboratory sustainability. Over two dozen Caltech research groups have gained recognition as Green Labs.
Despite a tumultuous last few years full of waste challenges, Caltech began to prepare for a more resilient waste and recycling program through the work of the Sustainability Advisory Council. Revamping the on-campus recycling process and creating a more resilient staffing structure were key early priorities in 2024. Further considerations into creative reuse of materials being utilized on campus as well as smart purchasing strategies to avoid waste combined to help avoid waste and improve the overall diversion picture of the campus.
Some waste generation can be centrally managed: During construction, Caltech works with contractors to prevent construction waste and make sure that as much waste as possible is diverted for reuse or recycling. When the old Mead Laboratory was demolished to make way for the new Resnick Sustainability Center, construction workers sorted concrete, wood, and metal for reuse and recycling.
