Análise da envoltória pela norma de desempenho - ABNT NBR 15.575-4 e RTQ-R da tipologia de edifícios de habitação de interesse social em Belo Horizonte - MG

Abstract

The current pattern of construction has been evaluated in relation to performance and energy consumption. The performance standard NBR 15575, not yet in force, will require buildings to meet minimum performance requirements, which may change the basic cost of buildings. Energy efficiency regulations, such as the Quality Technical Regulation of the Level of Energy Efficiency of Residential Buildings (RTQ), establish minimum performance requirements for residential, commercial and service buildings, and although not mandatory, can serve as parameter for analyzes of the quality of buildings. In Belo Horizonte, several buildings are being implanted through the social housing policy, which has resulted in the resettlement of families living in areas of geological risk or in areas that are of interest to the public sector. These buildings have a low constructive pattern, hindering to implement improvements in relation to new techniques and materials. The aim of this work is to show the necessary modifications in this resettlement buildings implanted in Belo Horizonte city, about to the thermal performance of the walls and roofs, according the new standard, NBR 15575. As well as to analyze a possible labeling of the envelope by the standard RTQ-R-2010 (Residential buildings). The method used was the deductive methodology, as its results are based on the analysis of comparative data through established standards and formulae. The object will be a final case study paper analyzed through a non-probability sampling method by typicality, featuring research on a typical group, i.e. building typologies. The results allowed to conclude that it is possible to meet the new performance standard, NBR 15575, and to improve the level of energy efficiency, through simple solutions with low impact on the final cost of the buildings.
