Avalia??o do desempenho t?rmico e ac?stico em habita??es de interesse social ? estudo de caso em Governador Valadares/MG.

Programa de P?s-Gradua??o em Constru??o Met?lica. Departamento de Engenharia Civil, Escola de Minas, Universidade Federal de Ouro Preto.A constru??o civil no Brasil nos ?ltimos anos passa por um crescente processo de industrializa??o e evolu??o tecnol?gica. Por?m, as constru??es de baixo custo como as Habita??es de Interesse Social (HIS) ficam ? margem dessa evolu??o, com predomin?ncia de t?cnicas de constru??o convencionais, comprometendo a agilidade das constru??es e desempenho das edifica??es. As HIS constru?das em Governador Valadares/MG seguem um padr?o preestabelecido, sem adapta??es ?s caracter?sticas regionais socioecon?micas, culturais ou clim?ticas, podendo n?o atender as necessidades dos moradores e requisitos normativos de desempenho. Nesse contexto, o objetivo principal desse estudo foi avaliar p?s- ocupa??o o conjunto de HIS localizado no bairro Vit?ria em Governador Valares/MG, com foco no desempenho t?rmico e ac?stico. Foram caracterizadas as HIS na cidade e analisadas apercep??o e satisfa??o dos moradores do bairro Vit?ria quanto as resid?ncias por meio de aplica??o de question?rios estruturados. O desempenho t?rmico foi avaliado por meio de medi??es de temperatura do ar no interior de tr?s edifica??es do conjunto habitacional, entre janeiro e fevereiro de 2019, e, quanto ao desempenho ac?stico, foram medidos n?veis de press?o sonora internos e externos a edifica??es no mesmo per?odo do ano de 2019, em pontos diversos do bairro em turnos diurno e noturno, retratando diversas fontes externas de ru?do. Os resultados apontaram que as HIS na cidade predominantemente utilizam sistemas de constru??o convencionais, com dimens?es pr?ximas aos valores m?nimos do Programa Minha Casa Minha Vida, percebendo-se alta insatisfa??o nesse quesito entre os entrevistados, bem como quanto ? qualidade das constru??es. A popula??o tamb?m se mostrou insatisfeita com a infraestrutura do bairro e com o desempenho t?rmico das resid?ncias. As medi??es realizadas in loco identificaram que a temperatura do ar interno ?s resid?ncias esteve mais elevada que a temperatura externa durante maior parte do dia, n?o atendendo ao crit?rio de desempenho estabelecido na norma NBR 15.575 no ver?o. O desempenho ac?stico tamb?m foi identificado. As medi??es de n?veis de press?o sonora internas e externas ?s resid?ncias nos per?odos diurno e noturno n?o atenderam aos n?veis de refer?ncia das normas NBR 10.152 e NBR 10.151, embora maior parcela dos entrevistados mostraram-se satisfeitos quanto ao desempenho ac?stico das resid?ncias.Civil construction in Brazil in recent years is undergoing a growing process of industrialization and technological evolution. However, low-cost buildings such as Social Interest Housing (HIS) are on the fringes of this evolution, with predominance of conventional construction techniques, compromising the agility of buildings and performance of buildings. The HIS built in Governador Valadares / MG follow a pre-established standard, without adapting to regional socioeconomic, cultural or climatic characteristics, and may not meet residents' needs and regulatory performance requirements. In this context, the main objective of this study was to evaluate post-occupancy the set of HIS located in the Vit?ria neighborhood in Govenador Valares / MG, focusing on thermal and acoustic performance. The HIS in the city were characterized and the perception and satisfaction of the residents of the Vit?ria neighborhood regarding the residences through the application of structured questionnaires were analyzed. Thermal performance was assessed by air temperature measurements within three buildings in the housing complex between January and February 2019, and for acoustic performance internal and external sound pressure levels were measured over the same period. from 2019, in different parts of the neighborhood in day and night shifts, depicting various external sources of noise. The results pointed out that the HIS in the city predominantly use conventional building systems, with dimensions close to the minimum values of the Minha Casa Minha Vida Program, with high dissatisfaction among respondents, as well as the quality of the buildings. The population was also dissatisfied with the infrastructure of the neighborhood and the thermal performance of the homes. The on-site measurements identified that the indoor air temperature was higher than the outdoor temperature for most of the day, not meeting the performance criteria established in NBR 15.575 in summer. Acoustic performance was also identified. Measurements of sound pressure levels inside and outside homes during the day and night did not meet the reference levels of standards NBR 10.152 and NBR 10.151, although most respondents were satisfied with the acoustic performance of the residences
