Solution

TRC provided design, engineering, and construction services for the installation of an "intelligent building" system at the Pentagon, one of the world's largest office buildings.  TRC's two initial activities, part of the renovation program following the September 11, 2001 terrorist attack, included design, engineering, and construction of the Pentagon's Solar Energy Farm. The Solar Energy Farm consists of a photovoltaic (PV) system that produces more than 110kW of renewable electricity, and a 75.6kW solar hot water system that supplements domestic hot water requirements.

TRC was also involved in the design, engineering, and installation of a full­function digital control system at the Pentagon's heating and refrigeration plant. This system controls and operates the chillers and boilers to optimize the Pentagon's heating, ventilation, and air conditioning systems. The digital control system also coordinates electric circuits, lighting, sewage systems, and fire alarms. With this technology, the Pentagon monitors and manages its energy consumption with the latest HVAC, energy metering, and sub­metering technology.

"This showcase energy farm allows the Department of Defense to satisfy its renewable energy goals while promoting 'green' distributed generation technologies to other government agencies," said Bob Billak, Pentagon Reservation Energy Manager. Billak added: "TRC's knowledge of building systems coupled with its streamlined approach to our requirements resulted in flawless performance."
 
Under this contract, TRC provided:
• Design, engineering and construction of the Pentagon's Solar Energy Farm.
• Design, engineering and installation support of a full­function digital control system at the Pentagon's heating and refrigeration plant.
