Avaliação da eficiência energética de edificação educacional com base no novo regulamento brasileiro de etiquetagem de edificações públicas

Abstract

The quest for energy efficiency has led to major changes in the chain of building construction processes, from the extraction of raw materials to the development of materials and techniques. In the public sector, it is difficult to reconcile changes in legislation, planning and the need for resources to invest in infrastructure. However, this is one of the sectors in which energy efficiency is gaining momentum. The methodology for accessing the label was modified in 2022, with the Inmetro Normative Instruction for the Energy Efficiency Classification of Commercial, Service and Public Buildings (INI-C). The aim of this study was to verify the eligibility for the National Energy Conservation Label of Block E at UTFPR-Toledo Campus. The study used the simplified method of this normative instruction to assess the energy efficiency of the building. The results showed that the individual envelope, air conditioning and lighting systems were eligible for an A rating. In the overall assessment, the building under analysis achieved eligibility for Classification A for the National General Energy Conservation Label. Also, because it has two photovoltaic plants, the energy performance with the inclusion of the electricity generation system qualified the building for the category of almost zero energy building, with the potential to generate more than 50% of energy consumption. The development of the work showed that INI-C, specifically the simplified method, is a viable application, being intuitive and easy to use. With regard to Block E, although it was not a building designed to be eligible for ENCE, the assessment showed that it is qualified to do so under current conditions.
