Comportamento térmico de um protótipo de telhado verde: estudo de caso

Abstract

In the midst of a growing urbanization scenario, the scarcity of green areas combined with conventional building materials that absorb excess solar energy make today's energy and climate situation worrying. The various damages that the excessive use of energy and the devastation of vegetation cover bring to people's quality of life are well known, from energy scarcity to the extinction of non-renewable sources. In this context, the need to generate the thermal inertia of a building to avoid thermal discomfort inside is already a fundamental issue when considering the energy problems that may occur in the not too distant future. In this way, if a building has bioclimatic architecture artifices, it is able to ensure thermal comfort inside the environment during the hours of higher temperatures and incidences of solar radiation, controlling excess heat. In view of this, the green roof emerges as a constructive alternative beneficial to the local environment, minimizing environmental impacts and contributing to the thermal comfort of users, as it works as an insulation in the roof of buildings, an expressive factor to verify the energy efficiency by the use of extensive vegetation cover (green roof) compared to the use of conventional roofing. also analyzing the constructive variables of the green roof and verifying its performance and efficiency, a question to be developed in this research.
