Energy efficiency gains by LED luminaires in common areas' of shopping malls through transition from fluorescent lamps to LEDS: A case of mini-mall, Kisumu, Kenya

Abstract

The change in commercial lighting can be identified with the introduction of recent technologies like LED luminaires which are energy-efficient. The case study analyzed is for a shopping mall with an aim of making a comparison of the suitability and costeffectiveness between the existing CFLs and LEDs in the shopping mall. A layout design has been simulated to determine the number of required luminaires where the CFLs have been replaced using different LED luminaires in different sections. The design is expected to lower the amount of energy consumption by 43% and optimize quality of lighting in common areas of the mall. The estimated payback period is 1.2 years which validates the design that uses LED luminaires for commercial setups.
