Video tour of federal green roofs


Last week, I wrote about how federal agencies are using some of the billions of dollars in stimulus funds flowing to them for facility and energy projects to replace or retrofit their building rooftops with green alternatives.

Options being considered include thin solar films that are imbedded into roofs, additional insulation to repel heat, and vegetative roofs such as a 5,000-square-foot garden patch atop the seven-story Interior Department headquarters building in Washington.

Other agencies have outfitted their roofs with vegetation, recognizing both the environmental and economic benefits. Our videographer, Colin Kelly, recently toured two examples outside the nation’s capital in Suitland, Md. Follow the links for video of green roofs at the Census Bureau headquarters and at the National Oceanic and Atmospheric Administration facility.
