Desempenho térmico de habitações de interesse social com a tecnologia Woodframe na Zona Bioclimática 2:o caso do Residencial Haragano (Pelotas,RS).

Abstract

This study presents a diagnosis of the application of a technology used with Wood-frame panels for habitations of social interest of the residential set “Haragano” in the city of Pelotas, Rio Grande do Sul, Brazil, by the housing program “Minha Casa, Minha Vida” (MCMV) in order to evaluate their thermal performance for Summer and Winter conditions. The adopted methodology is based on the standards NBR 15575 (2008) – Desempenho de edifícios habitacionais and NBR 15220 (2005) – Desempenho térmico de edificações. Air temperature measurements were made in five housing units, located in the interior and on the edge of the tapes (adopted typology). To evaluate external and internal air temperature, measured in the selected houses, first, the analysis of typical Summer days to several levels of frequency of temperature occurrence were made, considering a historic series from 2009 through 2015, and then defined the external temperatures and their comparison to the internal temperatures.The confrontation with the standards on the prescriptive evaluation has showed that the habitations do not attend to the requirements of NBR 15220 and NBR 15575. In the measurement methodology “in loco”, the housing units presented a thermal performance within the requirements of NBR 15575, stressing that the units built on the edge of the tapes presented hotter temperatures during the period of Summer and colder temperatures during the period of Winter, what came to confirm the thermal sensation noticed by users through the application of questionnaires.
