The National Geospatial Intelligence Agency (NGA) New Campus East building is an eight-story, 2.4 million square-foot project in Fort Belvoir, Virginia with LEED® Gold certification. The campus, under construction in 2007 and opening in 2011, includes a technology center, central utility plant, visitor center and other structures. This $1.7 billion project aimed to consolidate seven existing NGA facilities into one building, designed by the US Army Corp of Engineers and McDonough Bolyard Peck.
 
The National Geospatial-Intelligence Agency is a Department of Defense combat support agency and a member of the U.S. Intelligence Community. As the nation's primary source of geospatial intelligence, the NGA is a high-security organization that requires a reliable, low-maintenance heating and cooling system. 
In this project, TROX USA provided active chilled beams type DID622 and passive chilled beams type TCB. In the New Campus East building, the Multi-Service Chilled Beams (MSCB) that integrate lighting services represent the first large application of these devices in North America. The beams were in various shapes and capacities according to the cooling load to be handled. There are approximately 4,178 beams in total in the NGA facility.
 
The reliability and low-maintenance nature of the TROX chilled beam system was an ideal match for the NGA building's high-security requirements. The chilled beams were also a key component to achieving both improved energy-efficiency and improved air quality in the building.

The installation of more than 4,000 TROX chilled beams in NGA’s New Campus East contributed to the building’s LEED® Gold certification for its efforts to achieve environmental sustainability. The use of the chilled beam system for heating and cooling resulted in smaller ductwork and a reduction in the necessary power for traditional air handling fans, one of the largest energy consumers in a building.
 
The chilled beam system allows for a measurable cut in energy use for the building’s cooling and heating. For example, four of the seven chillers providing cool air to New Campus East will be shut off during the winter, meaning that the entire facility will be cooled with fresh air brought into the facility through a rooftop unit.
