Abstract: About 20% of the electricity use in Hong Kong's hotel operations is for electric lighting. Life cycle cost technique was used in the analysis ofreplacing general lighting service (GLS) lamps with energy saving light bulbs in hotel corridors. Discounting approach was adopted to compute the net present value of electricity cost over a life cycle of five years. Two city hotels in Hong Kong were selected for the case studies. It was found that the simple payback period was about one year, and the reduction in electricity consumption and hence running cost could be up to 70% over the life cycle taken in this study. The corresponding reductions in green cost of electrical power generation and greenhouse gas (CO2) emission were estimated to be HK$114,800 and 420x103 kg, respectively, per year for the two case studies. This paper presents the work and discusses its findings and implications for energy conservation.
