LEVANTAMENTO E ANÁLISE DE DADOS DE CONSUMO DESAGREGADO DE ENERGIA EM ESCOLA PÚBLICA MUNICIPAL PARA RETROFITTING

Abstract

Complex buildings such as public schools in municipalities are seldom evaluated in post-occupancy situation in order to verify its compliance to the original designed performance or for upgrades. Besides there are lack of data about these buildings performance, since legal regulations are often restricted to the national scale, and because municipal schools are generally located in urban spaces with various vulnerabilities. This paper presents a case study using post-occupation energy assessment (POE) in the Municipal School Herbert José de Souza, located in Belo Horizonte, Brazil, in order to improve the energy efficiency of the building. Local data were collected and analyzed the disaggregated energy consumption of the building. Extensive observation techniques such as walk-through, tabulation, data representation and creation of proposal scenarios were used to understand the activities performed and the energy consumption resulting from the use of equipment and artificial lighting. After analyzing the collected data, it was possible to obtain satisfactory results of energy savings in the equipment system by means of exchange for more efficient equipment and with less power. In the lighting system there was also great energy savings with the exchange of fluorescent lamps by LED even if there was an increase of lamps in environments that did not meet the norm NBR 8995/2013. Among the conclusions, we highlight the fact that the methodology selected for the study was satisfactory, even though there were limitations in modeling the estimated consumption. POE in energy proved to be of great importance for a good proposal for the maintenance of public municipal school buildings.
