Abstract

This study presents the potential energy saving of total cost of ownership through the lighting system in 7 ELEVEn Taman Kota Laksamana(TKL), Malaysia. The survey results indicate that most of the lighting system at 7 ELEVEn Kota Laksamana consists of fluorescent lamp. Cost benefit analysis of alternate choice with more efficiency lighting system in terms of potential energy can be save, life cycle cost of ownership analysis have been conducted. Highest range of brightness at average 500lux are required according to MS1525, using new LED T8 30W 3000Lm (CH-T8N-5730W-88-A3) Fluorescent lamp can save approximate 12.6% of costing over ten years duration compare to existing Philips T8 3250Lm (TL-D 36W/827 1SL). While minimum brightness at 200lux accepted according to MS1525, by using LED T8 18W 1800Lm (CH-T8N-2835W-96-A3) fluorescent lamp was the best choice with same fitting by reducing approximate 46.8% of total cost compare to existing Philips T8 3250Lm (TL-D 36W/827 1SL) fluorescent lamp. LED fluorescent are most efficient lighting choice refer to lux/watt , but higher initial cost may be part of the factor result investor take more time to consider using LED technology. Comparison of existing and retrofitting of lighting system based on the energy consumption is presented. From the analysis, it can be concluded that by using energy efficient lighting system has save a significant amounts of energy, cost, and also indirectly reducing emission.
