Federal Center South has earned national recognition for its energy efficiency.

Federal Center South

Location: Seattle

General contractor: Sellen Construction

Owner/developer: U.S. General Services Administration

Primary designer: ZGF Architects

The Sellen team worked through a design-build delivery method to develop creative, cost-effective solutions to complex design, engineering and constructability challenges.

The state-of-the-art facility is expected to merit a LEED gold certification and become the region’s most energy-efficient air-conditioned building.

It is one of the first buildings in the region to combine the use of geothermal heating and cooling systems with structural piles. The geothermal energy wells extend 150 feet below ground and loop water for cooling and heating. The project has approximately 160 geothermal piles, which are used in conjunction with the entire hydronic system to optimize energy performance.

The project won first place for a high-performance building from the Sustainable Buildings Industry Council, and the American Institute of Architects honored it as one of the top 10 green projects in the U.S.
