Energy impact of lighting system replacement in a public education institution

Abstract

Lighting loads represent a significant percentage of global energy consumption, becoming an important issue to analyze in order to contribute to a more efficient use of electrical energy. This work presents an analysis of the lighting energy demand in the buildings of the College of Engineering - UNCPBA along with a proposal for improvement using LED technology. A survey of each of the buildings and spaces has been carried out to identify the current lighting conditions of the different College work areas and the associated energy consumption. The analysis includes the impact in terms of energy and lighting quality, replacement costs and return on investment. The calculation of greenhouse gases (GHG) and their environmental impact is also presented. The results of the study indicate that the transition to LED lighting would result in approximately 60% savings in electrical energy consumption at the College. The study draws conclusions regarding the efficiency of the lighting process and the reduction of environmental impact.
