Tokyo’s municipal government requires buildings with a roof area greater than 10,765 square feet (1,000 square meters) to cultivate at least 20% of the roof area The City of Linz in Austria has been paying developers to install green roofs since 1983 and in Switzerland it has been a Federal law since the late 1990s (Source: Wikipedia) On a 95°F day, a conventional roof membrane is 158°F, a green roof membrane is 77°F (Source: Metroplis magazine article) Heat loss of green roof as compared with conventional roof: 18% less (Source: Metroplis magazine article) According to Chicago’s Department of Environment, temperatures atop the green-roofed City Hall are typically 25-80°F (14-44°C) cooler than the adjacent tar-roofed county office building A study by Environment Canada found that if just 6 percent of Toronto's roof area was converted to green roofs, greenhouse gas emissions in the city would be reduced by 2.4 million tons According to Portland’s Bureau of Environmental Services, green roofs in Portland absorb significant percentages of the rain that falls on them (almost 100% in Summer, 40-50% in Spring and Fall and 10-20% in Winter) whereas conventional roofs absorb none. This removes stress from sewer systems and prevents untreated stormwater from entering rivers and streams.
