Due to the concentration or of buildings and to tr TRANSIT vehicular life in our cities has gone insane. Cars and heating n or consume scarce t ox geno today í d ay harmful substances produced in abundance. Huge areas CONCRETE ny asphalt or lead to an overheating atm sfera or urban areas and lead to the dirt and part í particles of harmful substances are deposited on the floor, climb on the heat generated swirl and spreads over the entire city. On summer nights reached in the middle of a big city, air temperatures between 4 and 11 ^or ° C m to s higher than in the suburbs ( L or tsch 1981). Ú Ins n L or tsch cities have up to 15% fewer hours of direct sunlight and an increased frequency of fog (30 to 100%) according to é little of a ñ o.

Gardens to front and landscaped courtyards, but mostly landscaped roofs and facades, may í definitely an improving climate for polluted cities, the air purifying í to be reduced í considerably an eddy of dust and variations in temperature and moisture percentages decrease an í. To achieve a healthy urban climate probably be í a sufficient covered with garden extensions with between 10 and 20% of all indoor areas of the city, because a roof c grass é unpruned has an average rate of 5 to 10 times more to s surface leaves it to in an open park area (see chap. 3).

If s or what for every five roofs had one of c é grass, the surface of leaves in the city will double í a.

Green roofs in addition s to influence the improvement climate of the city, also n é optimize aislaci or nt é rmic, storage building heat, and aislaci or n ac ú acoustic. In addition to s are considered long term, m to s econ or monkeys that conventional tires (see chap. 11).
