Abstract
Brazil ranks seventh among countries that consume electricity and, to avoid limiting consumption measures, it has been adopting several actions, the main one being the increase in the electricity generation park, through the construction of new hydroelectric and thermal power plants. However, several economic and environmental restrictions hinder the advancement of these practices. An effective measure, widely used in developed and developing countries, is the adoption of mandatory regulations or voluntary energy efficiency standards, which aim to control the increase in electricity consumption and promote energy efficiency in the various productive sectors. The building sector, which encompasses the residential, commercial, and public power sub-sectors, consumed 249.9 TWh of electricity in 2021, which is equivalent to 50.3% of the total consumed in Brazil, demonstrating that there is a need regulatory action in this sector. To reduce this consumption and promote the energy efficiency of non-residential buildings, in 2009 the Technical Quality Regulation for the Level of Energy Efficiency of Commercial, Service and Public Buildings (RTQ-C) came into effect, within the Brazilian Labeling Program (PBE) of the Brazilian Institute of Metrology, Quality and Technology (INMETRO). In 2021, replacing the RTQ-C, the INMETRO Normative Instruction for the Energy Efficiency Classification of Commercial, Services, and Public Buildings (INI-C) came into force, with significant changes in its evaluation methodology. This article evaluates the applicability of this new methodology, in simplified and simulation methods, in existing buildings. To this end, the new regulation was used in a federal public building, located in the city of Rio de Janeiro, with an area of 4,275 m², distributed over five floors, with a water-cooled direct expansion air conditioning system, and self-contained and split devices with different cooling capacities, totaling 326.33 TR. The final classification is presented for both methods, with indications of possible improvements to increase the energy efficiency classification of the building.
