Edificação eficente: comparação entre os métodos de etiquetagem de 2014 e 2021 no bloco da FAEN – UFGD

Abstract

The worldwide increase of electricity consumption has brought to light the search for the rational use of electricity and the generation from renewable sources. In this way, the concepts of efficiency and sustainability were created, shaping aspects of architecture and engineering for the construction of buildings designed with the idea of energy savings, better use of natural resources and energy self-sufficiency. To be considered an efficient building in Brazil, it needs to be evaluated for its envelope, lighting system and air conditioning system, resulting in a classification labeling. Since 2014, the process of rating followed a simpler model, however from 2021, the evaluation is based on the building’s primary energy consumption in order to improve the method. Therefore, this study worked on classifying a building of Grande Dourados Federal University through the two methods for comparative purposes, culminating in the same level of general classification, level “A”, being the highest level of efficiency in the 2014 method but not in the 2021, since the last one is more judicious and closer to the actual condition of consumption, evaluating the reduction in primary energy consumption of the building at 51,40%, pointing to improvements that can be made.
