Chicago Needs More Eco-Toupees

With Greenbuild fast approaching, Chicago Tribune architecture critic Blair Kamin addresses the impact of the city's green roofs: "The planted roofs amount to less than one-tenth of one percent of Chicago's more than half a million buildings. If you're trying to control stormwater or achieve other benefits associated with green roofs, such as trimming building energy costs and providing wildlife habitat, size matters. For now, at least, Chicago lacks a green roof critical mass." [GreenSource]
