New Green Roof for the Department of the Interior

The US Department of the Interior announced on Dec. 16, 2008 that a green roof located on the 3rd wing of the Main Interior Building in Washington, D.C was completed. The project was a "...partnership among Interior’s Office of Environmental Policy and Compliance, the General Services Administration, and the Department’s National Business Center. "

Washington D.C. has been know for storm water runoff issues and the city itself was sued by the Chesapeake Bay Foundation to meet EPA guidelines. This new green roof will do the following according to the press release:

  • Hold up to .7 inches of rain to reduce stormwater runoff entering the sewage system and reduce streambank erosion.
  • Shield the roof from the sun’s direct rays, which extends the roof’s life span, insulates the building during the summer and saves energy as well as mitigates urban “heat island” effects.
  • Improve air quality by filtering the air that moves across the plants and, through photosynthesis, convert carbon dioxide into oxygen.
  • Provide habitat for songbirds and pollinators.
  • Reduce noise transfer from the outdoors.
  • Provide a visually attractive sight for employees and visitors.
It has also been reported elsewhere that Interior is planning to put green roofs on all six of its buildings in the District of Columbia. This marks a positive step by the US government to the acceptance and use of green roofs.

It's great to see our Federal Government walking the walk when it comes to more sustainable design. This will be an important part of the Obama administration, and my client, the American Institute of Architects, has laid out a list of recommendations for our new president.
