The United States Department of Energy complex is one of two administrative complexes of the United States Department of Energy. It is located at 1901 Germantown Road in Germantown, Maryland, on a campus originally developed in the 1950s as the headquarters of the Atomic Energy Commission. The complex's original five buildings were designed by the New York City architectural firm Voorhees, Walker, Smith & Smith, a firm prominent in the development of laboratories and associated facilities. It was sited at what was believed to a distance far enough from Washington, DC to survive a nuclear blast on that city.
