Green Roofs
Ordinary rooftops blight our cities. Green roofs (which depending on the plants are not always green, but red, brown and other colors) provide pockets of nature within the urban landscape. They reduce heat in the city, provide stormwater relief, increase building insulation, and create biodiversity. In Europe, where green roofs are more common, it is estimated that they can last up to 75 years with minimal maintenance.
