Toronto Green roofs will be required on new buildings in Toronto starting next year after the city council Tuesday overwhelmingly adopted the most stringent and comprehensive green-roof rules of any city in North America. The new rules consist of a green-roof construction standard and a mandatory requirement for green roofs on all classes of new buildings.
“Toronto's by-law provides a new opportunity to strengthen the emerging practice of integrated green building design," said Steven W. Peck, president of Green Roofs for Healthy Cities, Toronto, which supported the measure. "The by-law breaks new ground on how to structure a mandatory green-roof requirement and the construction standard also contains important best practices that may prove to be a model for other cities.”
The rules are effective for new residential buildings constructed after Jan. 31, 2010, and for industrial and commercial buildings constructed after Jan. 31, 2011.
