After surveying its corporate members, Green Roofs for Healthy Cities (GRHC) revealed the green roof industry grew by 115 percent during 2011, up significantly from 28.5 percent growth recorded in 2010.
“We are definitely beginning to see results from policy support that has increased over the past few years,” said Jeffrey L. Bruce, GRP, Chair, GRHC. “The industry is also benefitting from the more than 500 accredited Green Roof Professionals (GRPs) in the market, who are committed to driving future industry growth.”
In the Top Ten US Metropolitan Regions Rankings, Washington, D.C. vaulted into first place, with more than 800,000 square feet of green roofs installed in 2011.
"We are proud that the District’s aggressive adoption of green infrastructure continues to pay off,”
said Washington, D.C.’s Mayor Vincent C. Gray. “This is evidence that the District is moving toward my vision for a sustainable DC and will lead the nation in implementing green practices and growing a green economy. We are fully committed to being number one again next year.”
