Diagnóstico energético de uma edificação com propostas visando a eficiência energética e a inserção de um sistema fotovoltaico integrado e interligado a rede elétrica

Abstract

In this paper the result of an energetic diagnosis, which is a strategy of energy conservation and energy efficiency is presented. To this was quantified consumption, eliminated the waste of electricity and used a methodology for systematizing more efficient actions applied to the building. The methodology consists of steps like preliminary visit to the installation, survey and data analysis, study of alternatives for end uses, determining the potential for electricity conservation, economic viability analysis of alternative proposals, tariff analysis and studies of independent generation. Additionally, a case study in a building located in Xanxerê/SC, where a detailed characterization of the building and its consumption and thus proposed some measures of awareness and the addition of an on grid PV system that generates 11,900 kWh is performed is presented per year with payback time of approximately 25 years.
