From parking lot to the world’s largest nonprofit LEED-NC Platinum building: Gates Foundation

Tuesday, June 5, 2012

The world’s largest charitable organization has transformed an urban Seattle parking lot into one of the greenest campuses in the nation. The new Bill & Melinda Gates Foundation headquarters is the current project highlighted by Eco-Structure, a magazine of the American Institute of Architects, with the campus’ progressive environmental strategies taking center stage.

The Foundation’s new headquarters is the world’s largest nonprofit LEED-NC Platinum certified building and second-largest LEED-NC Platinum building in the United States. Seattle-based architect NBBJ designed the project to position all employees within 30 feet of natural daylight, which is achieved through 10-foot tall curtainwall units. Enclos provided complete design/assist-design/build facade services for both boomerang shaped buildings, which include 300,000 square feet of custom unitized curtainwall and a vertical cable-supported structural glass facade. All systems were designed to high performance and security specifications, including blast requirements.

Additional sustainable features include green roofs, a rainwater collection system, and innovative cooling and ventilation systems throughout the campus.
