Washington University in St. Louis’ goal is to serve as a national leader in green building design and operations.


Washington University received its first LEED project certification in 2004. Since then, we have completed a total of 33 LEED certified projects. Twenty-one of the 33 projects have exceeded LEED Silver, including thirteen Gold and eight Platinum, for a total of 3.25 million square feet of LEED certified space. Thirty percent of university-owned space on the Danforth and School of Medicine campuses is now LEED certified. Find out more about each of the building projects.

Since 2010, twelve projects have met or surpassed our goal to be 30 percent more energy efficient than the ASHRAE standard for buildings — we benchmarked against ASHRAE 90.1-2007 from 2010-2015 and against ASHRAE 90.1-2010 from 2016-2020. Two of these projects, the Lofts of Washington University and the Sumers Recreation Center, achieved 46 percent and 63% greater efficiency respectively relative to ASHRAE 90.1-2007, significantly surpassing the goal at the time. Although three additional projects did not reach the 30 percent goal, they all achieved greater than 20 percent more efficient than the ASHRAE standard.
