Proposta de ações de eficiência energética: estudo de caso na Prefeitura Municipal de Varjão-Goiás

Abstract

The objective of this work is to present technical and economic feasibility studies of Energy Efficiency Actions in the Public Service. Through an analysis of the procedures provided for in the Energy Efficiency Program Proceedings (PROPEE) of the National Electricity Agency (ANEEL), a case study is carried out for the lighting and environmental conditioning systems of selected public buildings in the city of Varjão-Goiás. The Energy Efficiency Actions refer to the replacement of incandescent and fluorescent lamps with LED technology lamps. And the replacement of the current air conditioners with energy-efficient appliances. From the data collection of the currently installed system and analyzing the proposed system, the Energy Savings (EE) and Demand Demand Reduction (RDP) are evaluated over the course of a year. The economic parameter Cost Benefit Ratio (RCB) is obtained through the study, where it is possible to conclude that the proposed Energy Efficiency Actions are considered to be technically and economically feasible within the scope of PROPEE. The study also covers economic investment analysis studies, considering Net Present Value (NPV), Internal Rate of Return (IRR) and Payback. And through the investment methods it is concluded that the implementation of the proposed Energy Efficiency project is economically feasible.
