Survey Reveals Steady Growth for Green Roof Industry in 2006

May 25, 2007

Toronto /PRNewswire-USNewswire/ – Green Roofs for Healthy Cities, the North American green roof industry association, recently announced the results from its second annual Industry Survey of completed green roof projects in 2006. The survey indicates a growth rate of more than 25 percent over 2005, representing more than 3 million square feet installed in 2006. For intensive green roofs that typically incorporate larger plants, the growth rate was 110 percent in 2006.

"The green roof industry is growing rapidly in response to the pressing need for cleaner air, better storm water management, improved energy efficiency and more usable green space in our communities," says Steven Peck, founder and president of Green Roofs for Healthy Cities. "Green roofs have really captured many people's attention as a beautiful way to help fight climate change and save money. Green roofs deliver more public and private benefits than any other green building technology, so we anticipate that strong growth will continue into the future."

The City of Chicago, which has policies in place to support green roofs and urban greening, implemented the most square feet of green roofs in 2006 of any city, followed closely by Washington, D.C.

"My goal is to make Chicago the greenest, most environmentally friendly city in the nation and we are leading by example in our green roof development," said Mayor Richard M. Daley. "With over 1 million square feet of green roofs completed in Chicago and another 2 million in development, our city has truly embraced this practice as a way to help conserve Chicago for future generations."

This 2006 Top Ten Cities List, from the top down, by total square footage installed, includes: Chicago; Washington, D.C.; Wildwood Crest, NJ; Dulles, VA; Kansas City, MO; Phoenix, AZ; Milwaukee, WI; New York City; Portland, OR and Columbus, OH. Evidence of the rapidly growing industry is reflected in the steadily increasing number of delegates who attended the fifth annual Greening Rooftops for Sustainable Communities Conference, Awards and Trade Show.

Green Roof Background: Green roof infrastructure involves the use of technologies that incorporate drainage/filtering systems, quality waterproofing, root-repellency, engineered growing media and plants. The benefits of green roofs include a reduction in storm water run-off, better heat and sound insulation, energy savings, improved air quality and reduction in the urban heat island. Other benefits include increased park space, improved aesthetics, community gardening and biodiversity.
