T.C. Williams High Schools in Alexandria, Va. falls into the ranks of such environmentally forward schools as Glendale Middle School in Salt Lake City, Utah, as well as The Noble and Greenough School in Dedham, Mass., with a new eco-friendly facility.
With features such as a roof that helps offset heat in the summer—while collecting and storing underground water for running air conditioners and flushing toilets—the new building cost roughly $90 million to build, or around $10 million more than a regular school would. School officials, however, say that the money saved because of the building's efficiency will allow the added investment to pay for itself within a decade. ::NBC4.com
