Selección de un Sistema de Iluminación Seguro y Eficiente para un Aula de Clases Mediante Análisis de Decisión Multicriterio

This research presents the results of a study carried out in a standard classroom of a university in the city of Guayaquil with the objective of defining the of a university in the city of Guayaquil, with the objective of defining the ideal lighting system lighting system according to the fulfillment of certain relevant criteria to ensure energy efficiency, student safety and theenergy efficiency, student safety and the correct functioning of the teaching-learning process. the correct functioning of the teaching-learning process. Nine scenarios with lighting systems of different lighting systems of different characteristics were considered and subjected to the evaluation of a group were subjected to the evaluation of a group of experts through a hierarchical analytical multi-criteria hierarchical multi-criteria decision process (AHP). The decision criteria considered were: total power, average lifetime, acquisition cost, illuminance, uniformity, glare, energy efficiency, color rendering and energy savings. Among Among them, uniformity of illuminance was the most influential in the final decision according to the experts' criteria, and the experts' criteria, and the least important were glare and color rendering. and color rendering. As a result, the ideal lighting system is one based on LED technology that LED-based lighting system that meets the safety criteria available in international standards available in international standards, while guaranteeing an energy efficiency of 1.36 lm/W. efficiency of 1.36 lm/W and an expected annual energy saving of 64.29% compared to the current fluorescent system. current fluorescent system.
