AHP-based approach for lighting system selection in an underground parking

Abstract:

This research aims to identify the most suitable lighting system for an underground parking in an academic building according to international standards. Nine lighting systems scenarios were evaluated and the most suitable was selected considering experts criteria through an Analytical Hierarchical Process (AHP). The decision criteria considered were: total power, average lifespan, life-cycle cost, illuminance, uniformity, glare, energy efficiency, color rendering and energy saving, some of which were simulated through DIALux software. Among these criteria, the uniformity of the illuminance was the most influential criterion in the final decision according to experts' judgement. Contrariwise, glare and color rendering were the least important criteria. As a result, a LED technology lighting system with an expected annual energy saving of 35% turned out the most suitable for the indoor facility under study.
