SEATTLE-The Seattle District of the U.S. Army Corps of Engineers has moved into new headquarters at Federal Center South Building 1202, a design-build project led by ZGF Architects LLP and Sellen Construction. The 209,000-square-foot, high-performance building transformed an industrial brownfield warehouse site into the 21st century workplace, which is expected to merit LEED Platinum certification and an ENERGY STAR score of 100.

The 1202 building is anticipated to be the region’s most energy-efficient air conditioned building—using one fifth of the estimated energy for a standard office building in the Northwest.  It uses an innovative “Phase Change Material” that releases and stores cold-energy to reduce the building’s cooling needs, according to a prepared statement, and it is one of the first in the region to combine the use of geothermal heating and cooling systems with structural piles.
