GSA Building Systems Project (IRS)

This American Recovery and Reinvestment Act (ARRA) project, part of GSA’s National Deep Energy Retrofit Program, involved an extensive field survey of the 546,000 square foot IRS facility and replacement of the entire roofing system to increase overall building envelope efficiency and implement the approved Energy Conservation Measures (ECM).

Tectonic replaced facility chillers and boilers for optimum energy efficiency of the complex, demolished five of the six existing chillers and all existing central plant piping. New chiller system controls were added to accommodate optimized chiller operations which allowed N+1 redundancy. Tectonic also replaced the existing boiler plant with new high efficiency hot water boilers that were dual fuel condensing boilers with a modular arrangement to provide N+1 standby capacity.

Tectonic had to receive clearance from Homeland Security and observe extensive measures while on site.
