Green Roof
Green roofs provide a rainwater buffer, purify the air, provide roof insulation, regulate indoor temperature, reduce energy consumption, encourage biodiversity in the city and help moderate the heat island effect. There are three types of green roofs: extensive, semi-intensive, and intensive green roofs. An extensive green roof is characterized by its low weight, a thin layer of growing medium, a mix of plants adapted to conditions on the roof, minimum maintenance, and low installation costs. A semi-intensive green roof has a thicker layer of growing medium to broaden the range of plants, involves more maintenance and irrigation systems are sometimes essential. Intensive green roofs have the highest maintenance, have deep soils with permanent irrigation, and are suitable for lawns, shrubs, trees, and walkways.
