Avaliação dos Parâmetros de Desempenho Térmico da NBR 15.575/2013: Habitações de Interesse Social na Zona Bioclimática 2.

Abstract

The projecting instruments and directions are essential for helping in the country architecturing view. The surveys’ developments from thermal performing contribute for the projecting strategies. This work helps to the subject through the prescripting survey of 15.575 NBR (2013 ABNT), about its application on 2 bioclimatic zone in social interest habitions. Due to this, it was defined an HIS with limited specifications mentioned by 15.575 NBR (2013 ABNT). Afterwards, it was performed a combining configuration for the different parameters of the performing survey and, as a result, a total of 6912 possible combinations were done. From these, 300 combinations were selected and simulated, obtained by aleatory pattern by means of hypercube – latin method. The temperatures related to typical days of winter and summer were selected. At a second moment, it was performed an analysing employing (utilizing) proposal by grades/hour instead of analysing the typical days. At the analyses’ development after considering the simulating results, it was proposed a new reference values’ utilization both to grades/hour and the limits indicated in the rule (pattern), so that the anterior limits showed to be very high. For the new configurations, it was also employed a combining analysis with occupied edification following the technical rule of quality determination for the energetic efficiency level of housing edifications (RTQ-R). Consequently, it made possible the creation of another limit for attaching the performing level whether the building may be simulated on this way. The results which were found demonstrated that the criteria adopted by simulating method according to typical days would make easier the configurations’ approval with much low valves or above the limits from 15.575 NBR simplified method (2013 ABNT). The analysis showed to be more logical related to grades/hour and the approved configurations and these new limits adopted for grades/hour’ ones showed to be much more pertinent, raising difficulties for the configurations that are out of these limits and they could systematically be approved.
