The second installment in our series on green offices in the DC metro area is the new East Coast headquarters of the National Geospatial-Intelligence Agency (NGA) in Fort Belvoir, VA. The building received a LEED Gold rating, the second highest LEED rating and the largest federal government building to receive such a high rating (2.2 million square-feet). The office focused on three areas: water, energy and transportation. By collecting
rainwater and using low-flow fixtures, NGA saves about 3 million gallons of water a month. It also reduces energy use by 30% with efficient lighting w
ith motion sensors and transparent ETFE roofing to provide more natural daylight. Carbon dioxide emissions from cars are reduced by NGA encouraging their employees to use public transportation.
NGA also included healthier materials in their building, including ones with low or no volatile organic compounds (VOCs), which contain chemicals that can cause headaches, nausea, and eye, nose and throat irritation, among other things. Chilled beams are also incorporated into the building to further reduce energy use associated with heating and air conditioning, since these reduce the power used by the fans.
