Aplicação de conceitos de edifícios energia zero em uma edificação na Serra Gaúcha incluindo um sistema de energia solar fotovoltaica conectada à rede elétrica

Abstract

Society is becoming more and more depending of electric energy and civil construction is updating to follow this trend. That way, this research means to apply Zero Energy Building (ZEB) concepts and solar photovoltaic energy in a building in project phase on Campus 8 from UCS, in Caxias do Sul, through computing simulations. To this end, has been used the software Sketch Up to structure modeling and EnergyPlus to analyze energy consumption. Project changes will be made, based in the data acquired on the simulations, seeking energy efficiency. After that, will be project a photovoltaic panels system, through Solar Edge software, to achieve ZEB concept. At the end of this study, performing the changes on the project, an energy consumption saving of 11.37% was achieved, but the sizing was executed to achieve a reduction of 9.65% because that was the most cost effective. The system projected in the building could generate energy enough for 43.37% of the annual consumption, so, the installation of ground panels was recommended to the building achieve ZEB level. A financial analyze evaluated a payback in eight years and five months. [resumo fornecido pelo autor]
