Map It!


Built in 1969, 500 1st Street NW is located within walking distance of Union Station and the U.S. Capitol Building in Washington, DC. 500 1st Street NW was renovated in 1989 and 2010, and is occupied by a single federal government tenant. The office consists of nine stories totaling more than 129,000 square feet with two levels of below-ground parking. The facility is heated using gas fired boilers and a central cooling system which utilizes newly installed roof level chillers and a cooling tower. The Washington D.C. Capitol Hill submarket offers an abundance of amenities including 29 restaurants, five hotels, multiple government and private-sector companies within a five mile radius, and direct access to I-395 via New York and Massachusetts Avenues. Recognizing the potential to improve 500 First Street?s energy and financial performance, FPO turned to EPA's ENERGY STAR program for the tools and resources to benchmark the property?s energy performance.


A whole building lighting retrofit was completed in two phases, with office areas being upgraded first followed by stairwells and storage rooms, and other back-of-house areas. This process involved the replacement of T-12 fluorescent tubes with more energy-efficient T-8s, and the installation of electronic ballasts in place of the older magnetic ballasts. In addition, occupancy sensors were installed in common areas and all private offices. New fixtures with dimming ballasts and occupancy sensors were installed in stairwells so that light levels remain extremely low until a stairwell is occupied, when light levels rise to full level well before an occupant reaches each landing of the stairwell. Lobby lighting, which previously produced excess heat, was retrofitted with LED lamps, improving both light quality and occupant comfort in addition to dramatically improving efficiency.
