Estudo de caso do sistema de iluminação da Escola de Arquitetura da UFMG: análise do uso de energia e de medidas de conscientização

Abstract

The present work aims to analyze the user behavior influences in the energy consumption of a naturally conditioned institutional building. For this the Architecture School of the Federal University of Minas Gerais was used as a case study. The work, as well as the master's program, presents a multidisciplinary nature when it associates studies of artificial lighting, natural lighting, energy consumption and user behavior to understand the direct and indirect relationships between these. Thus, this study aims to verify the performance of the systems responsible for the consumption of energy in the building, establish energy efficiency strategies and develop awareness procedures that encourage the user to act on the artificial lighting system of the building. The methodology applied began with the energetic diagnosis carried out with inspection of the building and an analysis of the energy bills of the building in the last two years and the verification of the energy efficiency level obtained by the National Energy Conservation Label of the built building, issued in 2012. Subsequently awareness measures were planned aimed to inform users of the pattern of energy consumption of the School of Architecture and the importance of the user behavior to maintain the comfort levels and the installed systems performance. Results show that intervention measures implementation, which involve considerable investment in technology upgrading is not always an option because of the costs involved, or by other factors involving the management of buildings. Changes in operation and maintenance routines, and especially changes in the occupants behavior present themselves as viable and considerable power range solutions in efforts to reduce energy consumption.
