The expansion of new buildings, however, has not considered energy, especially lighting system, in the design stage. This paper presents the optimal energy management design of lighting system for the bank buildings in the countries along Mekong River, namely China, Vietnam, Cambodia, Myanmar, Laos and Thailand. The lighting system is considered in the study as most of the countries use T8 fluorescent luminaires. The LCC (life cycle cost) method has been considered for the installation and operational cost. The assumed benefit-cost ratio analysis comprises of the lifetime cycle, price of fluorescent lamps, electricity unit price, operating times and hours of lighting bulb. The T8 fluorescent luminaires with low watt loss ballast are compared with T5 fluorescent luminaires and LED lamps. Electricity rates and the cost of the investment are considered to determine the suitable selection of the lighting system in each GMS country.展开更多
