Abstract: Green roofs are considered to be an effective solution to improve internal and external environment at the building and urban levels. In comparison to conventional roofs, green roofs present many benefits, such as reducing the temperature of the roof surface and surrounding air, reducing the air pollution, mitigating noise, improving the management of runoff water, increasing the urban biodiversity, and the reducing the energy consumption of buildings, especially for cooling purposes, Research has shown that green roof temperatures can be 30–40°F lower than those of conventional roofs and can reduce city-wide ambient temperatures by up to 5°F. In addition, green roofs can reduce building energy use by 0.7% compared to conventional roofs. This paper will use, a dynamic simulation of a building situated in the Campus University of Palermo, Italy, in the comparative analysis of green roof energy saving and normal conventional roof showing the importance of green roof over normal conventional roof. Two different situations were taking into consideration; in the first one, the building as it is, with a conventional covering, while in the second one the roof was equipped with a green roof. The results of the two simulations have been compared, recommending that application of green roof could contribute to the energy savings of the building.
