Exploração de recursos renováveis em escolas públicas: caso Escola Estadual Ensino Fundamental Eduardo Vargas

Abstract

This manual is the type of procedure that enables the production of renewable energy, such as solar energy, photovoltaic energy, photovoltaic energy and the generation of electricity and rainwater collection, as an alternative to reduce costs and energy diversication in school buildings. For this, an exploratory research was carried out, through a case study at the Eduardo Vargas State Elementary School located in Alegrete, State of Rio Grande do Sul. Analyzes of the economic and financial viability of solar photovoltaic energy, thermal heating system by solar collectors and rainwater harvesting system were carried out. Economic indicators were used, such as discounted payback, net present value, equivalent annual value. The results revealed the feasibility of the projects of photovoltaic energy system with and without energy eficiency study, Thermal Collector Heating System and Rainwater Harvesting System. Since all possible investments have a return within a maximum period of 10 years. In this way it was verified that the economic, social and environmental viability of the exploitation of the renewable energy resources, still serving the school as instrument of difusion of the new technologies of sustainable energy transformation.
