The new U.S. Army Corps of Engineers Seattle District Headquarters is set to be in the top 1% of greenest buildings in the U.S.
Federal Center South is targeting an ENERGY STAR score of 100 and, with a design EUI of 24 kBtu/sf/yr, achieves a 75% reduction in the fossil fuel energy over a typical office building in Seattle.
The building uses narrow floor depths and an atrium skylight for extensive natural daylighting, optimizes shading devices for passive heating, and integrates natural ventilation and passive chilled beams to minimize energy consumption. Geothermal heating wells provide on-site renewable energy. The building also collects and stores rainwater, restored a Superfund site, and recycled or salvaged nearly 99% of construction waste.
