All new buildings and major renovations must be built to LEED standards. There are currently 14 LEED-certified buildings on campus, including the first LEED-EB Gold building in the country, and 5 additional buildings meet LEED criteria and are awaiting certification. In addition, several spaces have been repurposed for alternative use. Emory has implemented low-flow faucets and showerheads, waterless urinals, drip irrigation, condensate recovery, greywater reuse, and rainwater harvesting to conserve water.
