Federal Center South Building 1202 Adds To List of Nearly 30 Awards with Recent Recognition from ASHRAE and USGBC

SEATTLE (December 4, 2014) – There are public buildings, and there are stars, and all sustainability measures indicate that the U.S. General Services Administration’s (GSA) 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.

ASHRAE Technology Award
The ASHRAE Technology Award recognizes buildings and teams for design innovations that incorporate the organization’s high standards for effective energy management, indoor air quality, and mechanical design, and Federal Center South Building 1202 was one of only nine buildings in the country to receive the highly-esteemed, first-place award. Federal Center South was judged on energy efficiency, indoor air quality, thermal comfort, innovation, cost effectiveness, and environmental impact. Federal Center South

LEED Platinum Certification
Federal Center South Building 1202 is one of the seven GSA buildings to earn a LEED Platinum certification for New Construction, the highest sustainability measure a facility can attain under the USGBC’s certification standards. The building earned 80 out of 110 points on the LEED Platinum certification assessment, scoring high numbers for energy efficiency, water efficiency, indoor environmental quality, materials and resources, and sustainable sites.

In addition to the ASHRAE Technology Award and the LEED Platinum certification, the Federal Center South Building 1202 has received 28 other recognitions, which include a 2013 National Design Build Award from the Design-Build Institute of America, an Honor Award - First Place for a High Performance Building from the Sustainable Buildings Industry Council, and a Environment Top 10 Green Projects award from the American Institute of Architects Committee on the Environment.

GSA Regional Administrator George Northcroft said:
“GSA and our federal partners are committed to building green to help reduce the federal government’s consumption of energy and water, and increase our use of clean and renewable energy sources. The recognition this building has received is proof that we deliver on that commitment,”

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 2x6 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.
