The Nature Conservancy's new headquarters is an eight-story 172,000 ft2 (16,000 m2) office building in the Ballston area of Arlington, Virginia. The Conservancy occupies six floors and leases two floors, which provide room for growth. Parking is accommodated in a garage below the building; the remainder of the site has been transformed into a 1/2-acre (0.2 ha) landscaped park. **This building was originally imported from the U.S. Department of Energy Energy Efficiency and Renewable Energy Building Technologies Database (http://eere.buildinggreen.com/overview.cfm?projectid=77) on 2009-06-06.
