Habitação de interesse social: tecnologias de conforto térmico aplicáveis e sua viabilidade

Abstract

With the objective of contributing to the reduction of the country's housing deficit, in 2009 the federal government created the Programa Minha Casa Minha Vida - PMCMV. The homes built by this program are called Social Interest Housing - HIS. They are characterized by compact housing units, away from urban centers, standardized and serialized, of low construction cost, which sometimes implies postponing the issue of thermal comfort. In fact, what is seen in buildings aimed at HIS, is a constructive simplification that, under the argument of limited costs, ignore such precepts, despite the benefits that thermal comfort in an environment brings to its users. Concomitantly, the average global temperature is getting higher and higher. According to the World Meteorological Organization - OMM (2019), currently, the planet is 1,1 ºC above the pre-industrial era (1850-1900) and +0,2 ºC that in relation to 2011-2015. Thus, the present work aimed to analyze the feasibility of applying thermal comfort technologies in a HIS project built in housing programs in the city of Goiânia-GO. For this purpose, a standard house model was used, for which improvements were suggested, according to the research developed in the literature review. Soon after, the costs for the construction of the original residence were estimated, using budgeting techniques. Thus, a parameter was obtained to analyze the executive viability of the solutions in new HIS’s. It is concluded that, when considering the countless benefits that better conditions of thermal comfort provide to residents, the 3,04% percentage increase in executive expenses is feasible.
