Avaliação da eficiência energética do prédio da Secretaria de Meio Ambiente de Maracanaú segundo o RTQ-C

Abstract

This work was carried out with the purpose of evaluating the energy efficiency of the building of the Department of Environment of Maracanaú and, thus, determining the ENCE (National Energy Conservation Label) of the building. The labeling of buildings in Brazil is part of the Brazilian Labeling Program (PBE), which in turn guides how the efficiency level, ranging from A (more efficient) to E (less efficient), will be determined. The prescriptive method of RTQ-C (Technical Regulation of Quality for the Energy Efficiency Level of Commercial, Services and Public Buildings) was used to determine the energy efficiency of the building. For this, some parameters of the building are evaluated, such as envelope, lighting and air conditioning System. The Envelope was rated A level. The Enlightenment system reached the C level of labeling. The air conditioning system was able to reach level B of labeling. Finally, the studied building obtained, in the general classification, level B of labeling. Some measures such as retrofit in the lighting system in order to take advantage of natural lightning and thus keep off the lamps near the windows; and the exchange of air conditioners with more efficient equipment, can raise the classification level of the building.
