As part of a comprehensive strategic plan for sustainable operations, Washington University in St. Louis has adopted a LEED Silver minimum as a standard for all new construction and major renovations. Project teams are charged with surpassing the minimum standard whenever possible. In addition, all new construction and major renovations must achieve a minimum of 30% more efficient than the ASHRAE 90.1-2007 energy efficiency standard.
Washington University received its first LEED project certification in 2004. Since then, the university has completed a total of 21 LEED certified projects, with an additional three projects pending. The certification portfolio includes nine Gold and two Platinum, for a total of 1.95 million square feet of LEED certified space; 15% percent of university-owned space is LEED certified.
Another significant achievement is the Living Learning Center, one of the first buildings in the world to receive Living Building Challenge certification, the most stringent green building rating system. A net-zero energy and net-zero water building, the Living Learning Center is part of our ecological field station, Tyson Research Center, located 30 minutes west of the Danforth Campus.
Since 2010, seven projects have met or surpassed our energy efficiency goal of 30% more efficient than ASHRAE 90.1-2007. Two of these projects, Hillman Hall and the Lofts of Washington University, achieved 41% and 46% greater efficiency respectively, significantly surpassing the goal. Although three additional projects did not reach the 30% goal, they all achieved greater than 20% more efficient than the ASHRAE standard.
High performing green buildings continue to be a cornerstone of the University's commitment to operational sustainability.
