Análise do Desempenho Térmico e Lumínico de uma Unidade Habitacional: Residencial Santos Dumont – Montes Claros

Abstract

This work propose is the evaluation of the performance of a typical social interest housing unit of Programa Minha Casa Minha Vida (PMCMV). The case study chosen for this work was a unifamily housing unit, designed according to the minimum specifications for this typology for the population with income range from 0 to 3 minimum wages, in Santos Dumont Residencial, in the city of Montes Claros in Minas Gerais. The first step consists of a evaluation according to established performance thermal envelopes of NBR 15.220 (ABNT, 2005), NBR 15.575 (ABNT, 2008); and evaluation of the prerequisites of the envelope transmittance, thermal capacity and thermal solar absorptance of surfaces RTQ-R (BRASIL, 2012a). The second step consists in evaluating the envelopes according to the Prescriptive Method RTQ-R (BRASIL, 2012a). The efficiency levels noted for the evaluation of prescriptive method are low and "C" is the maximum level obtained. The final step is to propose changes to the housing unit selected in the study case in order to achieve the “A” classification of efficiency level by the prescriptive method of the RTQ, so that, while maintaining the reduced cost of the units, the basic premise of the Programa Minha Casa Minha Vida (PMCMV), the units present greater thermal and lighting comfort and performance.
