Trinity has had several buildings be LEED certified. Buildings that have been certified include:
Trinity does their best to conserve and reuse water wherever possible. Current initiatives include using recycled water for landscape irrigation, replacing fixtures with water-efficient, low-flow plumbing fixtures and using air conditioning condensate for flushing in the Center for the Sciences and Innovation.
Throughout campus, initiatives and improvements have been put in place to increase energy efficiency. Trinity participates in CPS Energy's Automated Demand Response program to both conserve energy and reduce demand during peak usage times. Energy recovery wheels reduce the need for cooling, humidification and heating energy in the Center for Sciences and Innovation, and efficiency features are built into the Central Plant Consolidation combining multiple thermal utility plants on campus. Additionally, building submetering takes place to assess effectiveness and monitor energy consumption and insulating glass, high-efficiency lighting and lighting and thermal control sensors have been added in buildings across campus.
