ENERGETIC INFLUENCES OF GREEN ROOFS ON BUILDINGS: A REVIEW

Vlad Tudor DOBRA

Abstract


The main purpose of this paper is to present a review of the energetic influences of green roofs on buildings. The direct energetic influences of green roofs on buildings are related to the influences on the air temperature inside and outside of the building, the roof surface temperature, the heat flux transferred into the building through the roof, the albedo value of the roof. Indirect energetic influences are related to the costs with the heating and cooling. This paper indicates that the influences on the parameters presented above are dependent on the type of the green roof used. In literature, green roofs are considered to be a passive cooling method rather then a thermal insulation method.
