Análise comparativa da temperatura interna de ambientes com telhado verde e telhados convencionais de cerâmica

Abstract

Roofs located in tropical locations are exposed to high levels of solar radiation that influence the cooling costs of air-conditioned buildings and thermal comfort in non-air-conditioned buildings. Mitigating heat gains through the roof is one of the ways to reduce energy costs and provide thermal comfort to users. The green roof can be understood as a system that has vegetation cover made of green hedges. The implementation of green roofs is a way to compensate for the large reduction in green area in an urban environment. The main objective of this article is to evaluate the internal temperatures of an environment with a cover consisting of grasses, in order to create a green roof and compare the behavior with conventional ceramic roofs. To carry out an experiment of the experiment, two MDF prototics were built, one covered with a green roof and the other with a conventional ceramic roof covering. The results showed that the prototype with green roof had lower internal temperatures in the daytime when compared to conventional ceramic roofs. In general, the use of green roofs proved to be a viable and sustainable alternative for improving thermal comfort, in relation to the classic conventional ceramic roofs.
