Análise do método de simulação de desempenho térmico da norma NBR 15.575

Abstract

Buildings performance standards have as main purpose to evaluate and normalize the construction segment, ensuring a minimum quality and performance benchmark for residential buildings. Based on that, this study aims to apply and evaluate the simulation method presented in the NBR 15575 to assess the thermal performance of residential buildings. It was noticed that this method has limitations as it evaluates the building thermal performance based on summer and winter typical days. As a result, a new simulation method proposal was develop during the public consultation of the NBR-15575, which is based on heating and cooling degree-hour. The results from the comparison of both methods showed that the minimum requirement was achieved by the simulation method presented in NBR 15575 when compared with a concrete wall construction of 5 cm. But, for the new method proposed it was observed an unsatisfactory thermal performance for the same wall construction
