Aplicação do RTQ-R em uma habitação de interesse social

Abstract

With the increasing awareness of sustainable development in the construction industry, the implementation of procedures for the energy evaluation of buildings is becoming important, even so, these procedures do not reach the Social Interest Housing (HIS) segment due to the use of minimal resources. In this way, the objective of this research is the study of several constructive solutions and systems, in order to obtain a greater energy efficiency of a singlefamily residence, reducing energy needs of the same. This work presents an analysis of the energy performance of a typical building of the MCMV (My House My Life) program, located in the city of Dourados in the state of Mato Grosso do Sul (MS), of Bioclimatic Zone 3. Thus, a study was made of the requirements of the enclosure, water heating and subsidies provided by the Brazilian label, PROCEL Edifica, created by the Ministry of Mines and Energy in partnership with the Federal Government. The prescriptive method of the Brazilian Energy Labeling Schemes for Residential Buildings (RTQ-R) of PROCEL was used as a basis. A level of efficiency C was found for the building under study. Thus, measures were proposed to improve the level of efficiency obtained, such as the modification of the external absorptivity of the residence; the heat absorptions influenced by the shading of the openings and the influence of the water heating system. Some of these actions have resulted in raising the energy efficiency level of the popular home.
