Comparative Analysis of LED Commercial Lighting Systems

Abstract:

This study compares seven different LED commercial lighting systems using Life Cycle Assessment methodology. The environmental impact of seven LED systems was assessed in a baseline study in 2010 and monitored in 2012. The next monitoring phases are planned in 2013, 2014 and 2015. The ReCiPe endpoint method was applied to calculate the environmental impact. The results of the baseline study show that the main environmental impacts of LED lighting systems are a result of the use phase. The differences between the seven systems were mainly due to energy consumption, energy efficiency and the level of produced light (luminance).The on-going environmental performance of the different LED lighting systems was monitored based on these Key Environmental Performance Indicators (KEPIs). The first evaluation took place in 2012. The results show that compared with the baseline study, the environmental impact has increased for six out of the seven LED lighting systems mainly as a result of a decrease in luminance.
