ArchDaily recently named our GSA Federal Center South Building 1202 to its Top 100 Projects in the United States. The Top 100 American Architecture Projects is meant to “highlight the 100 most visited works of architecture in the US, turning them into case studies and references for millions of architects, students and journalists that seek the most important, inspiring works of American architecture.”
ZGF designed this LEED-Platinum certified, 209,247 SF facility, which transformed a brownfield, industrial warehouse site into a highly flexible and sustainable workplace for the U.S. Army Corps of Engineers (USACE) Seattle District headquarters. The concept for the building—the Oxbow—provides the greatest flexibility for work groups to expand and contract as needed, while the narrow floor plate optimizes daylight penetration. Open plan workstations surround the central “commons” that houses all shared resources, including conference rooms, kitchenettes, the library, and informal seating areas to encourage interaction and create a sense of community. The design integrates active and passive systems, materials, and strategies to achieve aggressive water and energy saving requirements. The project is one of the first in the region to use structural piles for geothermal heating and cooling, as well as phase change material and thermal storage. Chilled sails and open office lighting were developed and manufactured specifically to help achieve aggressive energy targets. Daylight, solar control, an intelligent envelope, and a rainwater reuse system are also all integral to the high-performance design. The reclamation of 200,000 board feet of timber from a warehouse previously located on the site provides a dramatic interior environment. The building’s optimized form, systems, and orientation will enable the building to perform within the top 1% of energy-efficient office buildings across the country.
