Balanço energético de um laboratório de pesquisa em cenários pré, durante e pós pandemia, visando certificação NZEB

Abstract

Photovoltaic systems have an essential role to improve the energy efficiency of buildings, so that when integrated, it works directly on the energetic balance, with a percentage of load to be compensated by the renewable energy source, important parameter according to latest efficiency requirements. National building labeling is already mandatory for federal buildings, demanding, among other requirements, the compliance of new procedure named Instrução Normativa Inmetro para a Classificação de Eficiência Energética de Edificações Comerciais, de Serviços e Públicas (INI-C), that replaced the old procedure named Regulamento Técnico da Qualidade para o Nível de Eficiência Energética de Edificações Comerciais, de Serviços e Públicas (RTQ-C). The new procedure brings criteria and methods for classifying energy efficiency for commercial, service and public buildings, aiming to obtain labeling buildings. The new instruction also includes the distributed generation in energetic balance of building, as well as the definition of NZEB buildings and carbon dioxide emissions evaluation method. Since 2020, the world has been experienced an exceptional period of the Covid-19 pandemic, and by changing the social dynamics, introduced temporary or permanent transitions in energetic balances and standards of buildings electricity consumption at the whole planet, due to geographic extension of pandemic effects. In this regard, this study seeks to present an analysis of the energetic balance in different chronological scenarios for the building named Centro de Excelência em Eficiência Energética da Amazônia (CEAMAZON), a public institution of Research, Development and Innovation, linked to UFPA, located in the Science Park and Technology of Guamá. Additionally, it shows a short analysis of the new INI-C related to the NZEB and carbon emissions evaluation methodology, considering the new implanted distributed generation system, and the electric vehicle charging station located nearby, highlighting the set of building characteristics that can classify its energy efficiency, and demonstrating essential parameters for certification.
