Energy efficiency analysis of a public building in the city of Vitória considering PBE-Edifica

Abstract

The Technical Quality Regulation for the labeling of commercial, service and public buildings (RTQ-C) is responsible for establishing the requirements for obtaining the National Energy Conservation Label (ENCE) by the National Institute of Metrology, Quality and Technology (Inmetro). However, the RTQ-C has several limitations and, to overcome them, the “Inmetro” Normative Instruction for the Classification of Energy Efficiency in Commercial, Service and Public Buildings (INI-C) was published in February 2021. This study was aimed to compare the assessments made by the methods foreseen in the INI-C for the same building. The object of study was the Professor Sebastião Magalhães Carneiro Building located at the Federal University of Espírito Santo (Ufes), in Vitória/ES. To achieve the research objective, the buildings parameters were collected by digital means and, then, the building was evaluated by the methods of INI-C. As a result, a Level D classification was obtained by the simplified method of INI-C, different from the Level D classification obtained by the simulation method. There was also a difference in the thermal load obtained by each of the used methods, with a 31% variation between the values approximately.
