(IS-2013-70) Green Building Performance


This report from GSA Public Building Service examines green buildings in order to compare them with the national averages to see how much more efficient they truly are. the General Services administration (GSA) selected 22 representative green buildings from its national portfolio, including 12 buildings whose performance was assessed initially in 20071.The evaluation was comprehensive, measuring environmental performance, financial metrics, and occupant satisfaction. Results were compared to both industry and GSA baselines. The results of the study confirmed that, on average, GSA’s sustainably designed buildings use less energy (25% less) and water, emit less co2 (36% less), cost less to maintain (19% less), and have occupants who are more satisfied (27% higher) than those working in typical buildings.
