Análise de edifício para classificação do nível de eficiência energética pelo RTQ-C: etiqueta parcial da envoltória

Abstract

The present study analyses the labeling of a building for locker rooms and dining halls located in the city of Macaé, RJ. Its aim is to make an accurate diagnosis of Energy Efficiency in accord with the methodology proposed by the prescriptive method of the Technical Requirement of Quality of the level of Energy Efficiency of Commercial, Service and Public Building – RTQ-C, by Procel Edifica. The data collection was carried out in order to characterize the construction over the documents of its draft. The research investigated the characteristics of the constructive elements, its location in relation to the Brazilian Bioclimatic Zoning, thermal performance of walls and roofing according to NBR 15220, analyzing the prerequisites and the consumption index of the labeling so as to obtain the National Energy Conservation Label for Constructions. The results indicate that the Efficiency Index of the labeling has reached level “A”. However, it has been observed that the absorption of solar radiation of the roofing has exceeded the utmost limits of this prerequisite, restricting the partial classification of the labeling to level “C”. For this reason, this study proposes improvements to the project of the construction by establishing constructive guidelines in order to get classification “A” of the level of energetic efficiency.
