Integration of renewable sources in buildings – case study

Abstract

Distributed generation has shown a great expansion in the last years with the improvement of new sources of energy. These renewable sources are increasingly efficient and accessible, providing more sustainable systems with less losses and lower environmental impacts. This work deals with possible configurations for a local electric power generation systems and the use of energy devices. A project for the improvement of a distributed generation system integrated to a building with an addition of a complementary source and of energy storage elements is made, aiming at reducing the energy consumption acquired from the local concessionary, islanding the building during peak hours, when the Rate is more expensive. Some of the characteristics and measurements carried out in the building of the Centro de Pesquisa em Energia Inteligente (CPEI) located at Campus II of the Centro Federal de Educação Tecnológica de Minas Gerais (CEFET-MG) are adopted as a basis.
