Abstract

The Technical Quality Legislation of the Level of Energy Efficiency of Commercial, Office and Public Buildings- RTQ-C, published in 2009, it is the first Brazilian instrument for regulating consumption of electrical energy in buildings. It classifies buildings into five levels of efficiency through the performance evaluation of the envelope, the illumination system and the air conditioning system. The aim of this work is to evaluate the energy performance from the TRT standardized publicbuilding through the regulation, to propose guidelines in order to improve the quality of this buildings adopted by the government. The research strategy adopted in this work is the case study of the building deployed in the city of Pedro Leopoldo. The envelope, illumination system and air conditioning system were evaluated through the prescriptive method of RTQ-C, and they were respectively classified as C, C and A, resulting the final classification B for the building. From these result, changes in the building were proposed in order it could obtain an A classification inenvelope and illumination system. Despite the satisfying result of the building envelope, it doesnt present good natural ventilation conditions, therefore studies regarding increase percentage of openings in the façade were tested, and solar shading devices were introduced to keep the best level of energy performance. Finally, the limitations to simulate natural ventilation and illumination, besides the impossibility of calculating the costs of all changes suggest the need for furtherstudies to develop a new project to be reassessed by prescriptive method associated with computer simulations.
