Both roofs were designed to help reduce stormwater run-off into the Anacostia River. The roofs were installed by D.C. Greenworks, a local non-profit organization that offers hands-on, green-centered apprenticeships. Rooms under a green roof are at least five to seven degrees cooler than the outside, according to Green Roofs for Healthy Cities. Green roofs can also reduce total stormwater run-off by 6%, according to other statistics.
Lars Etzkorn, director of the Office of Property Management, says that these two green roofs are the first of a number of green actions the agency is taking. "We are committed to the greenmandates of the DC Council and of Mayor [Adrian] Fenty's commitment in 100 Days and Beyond to achieve the highest possible LEED standards while offering job training for District youth," he says.
