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 21 LEED certified projects, with an additional three pending projects as of fall 2015. Eleven of the 21 projects have exceeded LEED Silver, including nine Gold and two Platinum, for a total of 1.95 million square feet of LEED certified space. Fifteen percent of university-owned space is now LEED certified. Since we adopted the LEED Silver standard, only one project was short of LEED Silver. This was the first project to use the LEED Commercial Interiors system, which still achieving the Certified level. Find out more about each of the building projects.

Since 2010, seven projects have met or surpassed our goal to be 30 percent more energy efficient than the 2007 ASHRAE standard for buildings (ASHRAE 90.1-2007). Two of these projects, Hillman Hall and the Lofts of Washington University, achieved 41 percent and 46 percent greater efficiency respectively, significantly surpassing the goal. Although three additional projects did not reach the 30 percent goal, they all achieved greater than 20 percent more efficient than the ASHRAE standard.
