Avaliação da eficiência energética : tipologia 3B da Escola Municipal de Ensino Infantil (EMEI) de Belo Horizonte - MG

Abstract

Building energy efficiency is a topic that is widely discussed by both private companies and public authorities and is the object of public policies. Its main benefit is safe money by building use, operation and maintenance. Specifically for the government, the cost-saving provided by energy efficiency allows public resources to be used in other areas, such as health and education. The purpose of this study is to determine the rating of energy efficiency of the artificial lighting system of a public kindergarten building model run by the city hall in Belo Horizonte, Minas Gerais, Brazil (Escola Municipal de Educação Infantil (EMEI)) using the simplified method provided in the national regulation (Instrução Normativa Inmetro para a Classificação de Eficiência Energética de Edificações Comerciais, de Serviços e Públicas (INI-C)). In this regulation, the model building is compared to the reference condition (level “D” of energy efficiency). It was noticed that the technical specifications of the artificial lighting equipment defined in the design of the electrical installations are adequate to the values for obtaining the “A” (maximum) rating of energy efficiency, however the activation scheme of the luminaires must be changed to enable the use of natural lighting in the rooms and, thus, the project will be able to receive the “A” level certification.
