The Washington Post reports that the Institute of Architects has recognized a new building on the campus of the Sidwell Friends School in Washington, D.C., “as one of the ‘top ten green projects’ of 2007″:

The building uses 93 percent less water than it would if simply hooked up to the city’s water and sewer system; energy efficiency and passive solar design cut energy use by 60 percent; and 78 percent of materials used were manufactured “regionally” (within 500 miles of the site) to cut the environmentally degrading effects of long transit.

It’s great to see environmental awareness spreading to all sectors of our society, including think tanks.
