Projeto e estudo da eficiência energética em iluminação de quadras desportivas: estudo de caso na unidade II - UFGD

Abstract

The continuous advancement of industrialization and technological innovations brings with it an increase in global energy demand, making the pursuit of rational use of electrical energy essential. Practices such as energy efficiency and energy management are developed with the aim of producing more while consuming less. Thus, this study seeks to analyze the lighting system of the sports court at the Federal University of Grande Dourados (UFGD), considering the ABNT NBR ISO/CIE 8995-1:2013 - Lighting of work environments and BS EN 12193:2018 standards. By measuring the illumination of the court using a lux meter, a parameterization of the measured results was developed, calculated using the lumen method and simulated in the DIALUX software. The same process was conducted for the sports court of the Ministry João Paulo do Reis Veloso State School, aiming to parameterize different lighting technologies, such as Light Emitting Diode (LED). The results showed similarity, strengthening the analysis when used together. The project for UFGD continued using the DIALUX software for Metal Halide and LED lamps, to meet the requirements of the standard, energy efficiency conditions, and ensure economic feasibility. The results obtained for the replacement of the luminaires were a return time on investment of 10 years, a Net Present Value (NPV) of R$ 53,762.71 and an Internal Rate of Return (IRR) equal to 36.85%. Greater benefits are obtained in a new project, when the investment analyzed is the difference between the projects: discounted Payback of 3.0 years, IRR equal to 107.53% and NPV of R$ 71,923.20 in 15 years. It is concluded, finally, that the two scenarios present economic viability the initial choice for LED luminaires, in option to the luminaire Metallic Vapors, obtains a gain in the return on investment of 7.0 years, in the IRR of 70.68% and in the NPV of R$ 30,339.05.
