The Green Proving Ground program, launched in 2011 and run by the General Services Administration (GSA) and the Department of Energy (DOE), was created to evaluate new private-sector green building technologies by installing them within federal facilities.
Sounds like a good idea, though te article is a bit light on ROI analysis. The program seems to have been put on a pause, if not outright cancelled.
