RESUMO:

In Brazil, the building sector is the highest electricity consumer, accounting for 50% of all electricity consumed. In Brazilian Federal University buildings, the electric expenses are one of the highest among the items of monthly expenses. It indicates the need for improvement in the use of energy, especially, considering the increasing budgetary constraints faced by these institutions. Due to this fact, this research with a case study at the Polytechnic School of the Federal University of Bahia proposes an investigation on the energy efficiency in university buildings, identifying the main opportunities for the rational use of electric energy. It was carried out a literature review focusing on the analysis of energy management methods applied to university buildings. Then, an energy review of the building was carried out following the ABNT NBR ISO 50001 standard. The analysis of energy use and energy consumption indicated that electricity is the institution's main source of energy and that the electricity consumption is concentrated on air conditioning systems, with 73% of representativeness. It was identified that the building´s laboratories are responsible for 45% of electricity consumption. The energy indicators were calculated to permanently monitor energy performance through comparisons with the baseline. The energy performance indicator “Energy Use Intensity” resulted in 55 kWh /sf /year, while the indicator “Average Consumption per Student” resulted in 62 kWh/student /month. Two significant opportunities for improving energy performance in the building were identified: the retrofit of lighting (replacement of fluorescent lamps with LEDs), and the retrofit of the laboratories' air conditioning (replacement of existing equipment with inverter air conditioning). Together both measures would result in a 24% reduction in annual electrical consumption, which corresponds to a cost reduction of R$ 379,573/year. The payback time of investment for these measures was calculated at seventeen months. Based on the results obtained, it was observed that the Polytechnic School of UFBA has the potential to improve its energy performance based on feasible and economically viable proposals. It is recommended for the institution to implement an Energy Management System (EMG) according to ABNT NBR ISO 50001 standard.
