Energy Efficiency and Distributed Generation: A Case Study Applied in Public Institutions of Higher Education

This study focused on developing a sustainability project carried out in 11 Federal Institute of Education, Science, and Technology Goiás (IFG) campuses wherein energy efficiency distributed generation actions were developed. Energy consumption was optimized by retrofitting the lighting system, installing photovoltaic (PV) quantifying building efficiency, monitoring, training, qualification, focusing efficient use electric energy. We first present Brazilian legislation that regulates Research Development Program sector. Then, we describe case applied to educational institution. In 18,377 inefficient lamps replaced with more technology, an saving 867.9 MWh/year peak demand reduction 309.6 kW. The proposed system aimed install 3076 PV modules roofs selected campus buildings, totaling 1 MWp installed power average annual 1736.9 MWh/year. total investment USD 1,348,768.50 overall cost–benefit ratio 0.68, which will result savings approximately 197,321.85. corresponded 58% bills. this work considered technically economically viable within scope Efficiency Program.
