Texas A&M University recently opened the Mitchell Physics Building in College Station. This building, like all new construction on campus, is LEED certified. LEED, which stands for Leadership in Energy and Environmental Design, is a national rating scale that focuses on sustainable building practices. The Mitchell Building was built at the silver standard of LEED certification, and it includes rainwater harvesting.
Rainwater and air conditioning condensate are captured from the rooftop and sent to an underground cistern (diagram below). This water is then used to irrigate landscaping in the front of the building (picture upper right) and the roof-top garden (picture upper left). This is the University's first roof-top garden.
