Eficiência energética e geração de energia fotovoltaica: estudo de caso na prefeitura de Sobral-CE

Abstract

This work presents a study of the energy efficiency measures applicable in Sobral City Prefecture. The actions were proposed based on the data collected during the technical visit, the lifting of loads and the energy bills, where an average monthly consumption reduction of 61.62% was estimated. For this, an analysis was carried out of energy bills and current lighting and air conditioning systems, seeking to reduce energy consumption, from the implementation of new systems with more efficient appliances. The study of the implementation of a photovoltaic system for electricity generation was also carried out and, through this, 35 % of generated energy is expected. A study was carried out of the economic feasibility study for the proposed new systems of lighting, air conditioning and photovoltaic, through the index of financial results, payback, net present value and internal rate of return and, with this, it was verified that all projects are economically viable. The quality of system and facility energy was verified by the study of electrical parameters that can cause disturbances that affect the performance of the system or the equipment and by means of a thematic inspection to determine the points that need maintenance and to carry out their classification of according to its priority.
