The Tennessee Air National Guard’s civil engineering building at Memphis International Airport has received the U.S. Green Building Council’s LEED Gold certification for environmentally friendly design.

The $7.3 million building, dedicated in December 2012, was the final piece of a $245 million, multiyear project to relocate the base within airport property and free up space for FedEx to expand its hub.

The 25,000-square-foot Base Civil Engineering Maintenance & Training Facility was designed by The Crump Firm architects, engineered by SSR Inc. and built by Chris Woods Construction. It has energy- and water-saving features and a rooftop solar panel installation to generate electricity.

The building council’s Leadership in Energy & Environmental Design program is a national standard for design, construction and operation of high performance green buildings. The air base project is The Crump Firm’s fifth LEED project and the first federally owned building in the region to be designated LEED Gold, the firm says.
