Influência dos materiais de fechamentos verticais e horizontais na eficiência energética de uma habitação unifamiliar térrea padrão normal em Santa Maria - RS

Abstract

More efficient buildings have a great impact on reducing national energy consumption, as they provide thermal comfort to their users with less electricity consumption. This work evaluated the impact that the use of EPS in vertical and horizontal closures, double glazing and high-reflectance tiles have on the energy efficiency of a single storey house in the city of Santa Maria/RS. The influence of different materials was analyzed using data from computer simulations performed in the EnergyPlus software, which allowed to determine, for the different construction typologies adopted, the annual electricity consumption of air conditioners and the level of thermal performance according to NBR 15575/2021. After carrying out the simulations, it was possible to conclude that the use of EPS as a thermal insulator in the roof slab provided the greatest reduction in the annual energy consumption of the air conditioning system among all individual improvements analyzed, with a value of 27,14%, followed by the use of EPS as an insulator in vertical closures and double glazing in transparent closures. The typology with high-reflectance ceramic tiles had lower energy performance compared to the typical typology due to the high consumption of electricity for heating, and the typology with all improvements showed the best performance, with a maximum consumption reduction of 45,88%.
