The new Leslie Dan Pharmacy Building is the most energy-efficient on St. George campus, according to The Varsity’s “CO2 Footprint Index.” We took the CO2 emissions for major U of T buildings, estimated by the Sustainability Office, and divided it by each building’s size. The resulting index indicates a building’s energy efficiency. U of T’s biggest offenders: large, old buildings like Medical Sciences and Robarts. Most thrifty are new buildings such as the Terrence Donnelly C.C.B.R. and Bahen Centre for Information Technology.
