The City of Chicago added the most square feet of green roofs in 2008 of any North American city, followed closely by Washington, D.C. and New York City, according to an industry association.
Green Roofs for Healthy Cities, the green roof industry association, also announced a 2008 U.S. growth rate of more than 35 percent over 2007, representing more than 3.1 million square feet installed in 2008. The data came from the association’s Fourth Annual Industry Survey of corporate members that completed green roof projects in 2008.
