Estudo de eficiência e viabilidade de sistemas de iluminação com tecnologias distintas para um ambiente industrial

Abstract

This work consists in an analysis of the lighting conditions and the presentation of proposals for the efficiency of the lighting system in a projects and engineering room of a metallurgical company located in the city of Criciúma-SC. It will be suggested lighting projects with different technologies, where the benefits of luminous efficiency, consumption, quality system and financial return of each project should be analyzed. For this analysis were considered environmental variables, with observations and measurements in loco of working conditions. It was made a contextualization of the regulatory standard and the concepts involved in the lighting calculations with this work. It was made analyzes of the present system, with presentation of the models and luminaires manufacturers, checking the conditions of the working environment, observing the minimum regulated level of illumination for the accomplishment of the task and finally measuring the levels of illuminance in the environment. As a way to standardize the measurements and analyzes, an electronic model was developed by Software Dialux, and it was carried out the simulations with the current project and the other proposals. As a way of comparing the proposed costs and methods, it was exposed the investments of each project, time of return (simple and discounted Payback), net present value (NPV) as well as investment return rates and a internal rate (TRI and TIR). By this way, we can evaluate the most feasible project for implantation in the environment of this study.
