Seattle Federal Building is a Sustainability Star

There are public buildings, and there are stars, and all sustainability measures indicate that GSA’s Federal Center South Building 1202 in Seattle is a star. Recently, the building — home of the U.S. Army Corp of Engineers Seattle District Headquarters — received a technology award from the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), and a LEED Platinum certification from the U.S. Green Buildings Council (USGBC).

These recognitions highlight Federal Center South Building 1202 role as one of the leading energy-efficient buildings in the country, and GSA’s ongoing commitment to building and maintaining high-performance green buildings, while reducing operating costs, saving taxpayer money, and providing a healthier work space for federal agencies.

Facts About Federal Center South Building 1202

  • The design-build team, led by Sellen Construction and ZGF Architects, transformed a 1940s warehouse into a 209,000-square-foot, 21st century workplace for the U.S. Army Corps of Engineers Seattle District Headquarters.
  • More than 190,000 board feet of timbers and 150,000 board feet of 2×6 decking from the old warehouse were reused for the new building. This amounts to almost 75 percent of the lumber from the old facility.
  • Innovative elements include a rainwater collection system that captures water and stores it in a 25,000 gallon cistern for use in toilet flushing, thermal storage that ‘stores’ cold-energy for future use, an energy-efficient HVAC system using under-floor air distribution, geothermal energy wells that extend 150 feet below ground and loop water for cooling and heating, and lighting controls that adjust to maximize daylight.
  • The project diverted 99.94 percent of the on-site generated construction waste from landfill.
  • 28.4 percent of the total building materials value includes materials and products that have been manufactured and extracted within 500 miles of the project site.
  • 32.22 percent of the total building materials content, by value, was manufactured using recycled material. and 10.69 percent of the materials are salvaged, refurbished, or reused
  • The project has implemented the reuse of rainwater for toilet flushing and irrigation, resulting in a total potable water use reduction of 62.5 percent when compared to a baseline usage for other newly constructed buildings.
