Abstract
The study deals with green roofs as an effective way to resolve many environmental problems. Green roofs provide many benefits compared to traditional roofs, and such roofs work to mitigate the impact of heat islands in cities, improve rainwater management as well as reduce air pollution and noise. They also help reduce carbon emissions in cities, and can thereby overcome the dearth of parks and green spaces.
In spite of the importance of using green roofs on buildings, the use of green suffering recently from increasing energy demand compared to production rates, especially in the residential sector as a result of high temperatures,, also green roofs helps in solving the problem of lack of preference of selecting the last floor of the residential building due to the problems of thermal and moisture insulation, where it work as an extra layer on the roof that reduces thermal strees on the roof of the top floor.
