Abstract

Efficient electrical energy usage has been recognised as one of the significant factors to reduce the cost of electrical energy consumption. In this world, hospitals are public buildings that use the enormous energy of other buildings. Due to its 24 hours service, the use of hospital building energy is estimated to be among the highest compared to commercial and residential buildings. In this research, the main building of Putrajaya Hospital has been selected. The main building covered by the first floor until the fifth floor will be focused to conduct this research. This research aims to identify energy consumption, cost savings and the provision of solutions to achieve the cost savings target of Putrajaya Hospital. The characteristics and location of the building were recognised at the beginning of the research. Besides, this study was continued by identifying the lighting system presented at Putrajaya Hospital and the electricity tariff published by Tenaga Nasional Bhd. The calculation of energy consumption and cost for each floor of the main building, starting from the first floor to the fifth floor proposed the energy saving method. Four potential savings methods are proposed later in this research which include the switch to LED lighting saving potential, occupancy sensor, regular maintenance, and reduce light operation hour by using the alternate system. The result was found that energy consumption can be reduced up to 73.38% by switching the current lamp to LED lamp.
