Green Roofs for Healthy Cities (GRHC) says its annual survey shows a 24 per cent growth rate in installed green roofs in 2012.

“On the heels of a huge 115 per cent growth rate in 2011, the green roof industry still grew by 24 per cent in 2012,” said GRHC founder and president Steven W. Peck. “Green roofs are being embraced around North America by policy makers, designers, building owners and developers,” he added.

In 2012, Washington, D.C. installed the most green roofs in North America with 1,326,872 square feet. Washington adopted a number of public policies that support green roof investment. Other North American metropolitan regions installing the most square feet were Chicago, New York City, Toronto and Philadelphia.

GRHC recently hosted Grey to Green: A Conference on the Economics of Green Infrastructure, in Toronto, on May 21 and 22.
