Desempenho termo-energético de habitações de interesse social produzidas pelo Programa de Arrendamento Residencial - PAR na cidade de Pelotas/RS.

Abstract

This paper evaluates the performance of thermal-energy social housing built by Residential Leasing Program - PAR in Pelotas / RS. The methodology is based on the NBR 15575 (2008) - Performance of residential buildings of up to five floors and NBR 15220 (2005) - Thermal performance of buildings. Measurements were made of air temperature and relative humidity in five apartments located in four different sets built with different construction systems in summerand winter periods. To evaluate the measured data in the apartments were analyzed using four parameters, they are air temperature, degree and degree-hour average, Bioclimatic Chart and NBR 15575. The confrontation with the standards showed that the dwellings meet most of the items that the NBR 15575 NBR 15220. The project with the best performance during the summer was the PAR Marcilio Dias, while the best performance during the winter was observed in PAR Regent. The main features that showed these results were the proper solar orientation, in the northern quarter, apartment regent of the PAR and the thermal characteristics of the external walls of the apartment PAR Marcilio Dias. It is observed that in most apartments are not used passive thermal conditioning strategies, which would increase the thermal performance of houses without significant increases in the costs of execution if the projects were executed more qualified. The study presents an analysis of the existing reality, which may serve as input to other studies and to improve the thermal performance of social housing in future housing units to be built.
