Projeto de eficiência energética aplicado em escolas públicas do estado Ceará: metodologia, aplicação e análise de cenários

Abstract

The purpose of this study is to describe the methodology used in an energy efficiency project financed by National Council for Scientific and Technological Development - CNPq that was applied in five public schools in the state of Ceará. Basic concepts of energy efficiency are presented with a brief description of the standard of procedures of Energy efficiency, PROPEE, made by the National Agency of Electric Energy, ANEEL. These concepts are used to support the proposal of methodology and data analysis shown in this study. The methodology strongly rely on energy diagnostics that aim to determine the energy saving potential and the financial feasibility of the project. The energy efficiency project ran from 2013 to 2014 being applied in five public schools of the state of Ceará. During this period, sets of data were collected, transformed and analyzed in order to find these facilities energy saving potential as well as the financial attractiveness of the project. In order to implement these analysis, visits were made to the schools in order to take measurements on the electrical installations and collect data regarding illumination, air-conditioning and daily working routines of the school. After collection and data analysis, improvement actions were suggested. Actions such as retrofit of the illumination and air-conditioning systems, as well as training and capacitation of the staff regarding energy conscious consumption. Scenarios of studies were simulated to predict energy savings.
