摘要：The electricity consumption in commercial places like universities has tremendously increased recently. Modern and advanced energy efficient appliances are highly needed to substitute the conventional ones. Energy saving is of great important instead of its wastage, as utilizing the energy efficiently reduces the cost of energy. Energy consumption varies for commercial building due to several factors such as electrical appliance usage, electrical appliance type, management, etc. Due to the advancement in technology, there are new emergence appliances that are of high efficiency and have less energy consumption. A case study is conducted on selected five tutorial rooms, level 4 buildings in the Faculty of Electrical Engineering 19 A, Universiti Teknologi Malaysia. The paper proposes new emergence equipments with high efficiency and less power consumption to replace the existing ones. A survey is conducted on the number of electrical appliances used for each of the tutorial rooms, time table for each tutorial room and the Tenaga Nasional Berhad pricing and tariff are taken into consideration in the analysis of the energy consumption and the cost of energy. This paper aims at reducing the amount of energy consumption by replacing the existing electrical equipments with high efficient electrical equipments; it also tends to reduce the cost of energy paid to the utility. By observing the results, it shows that the proposed efficient electrical equipments are more efficient, less power consumption and less cost compared to the existing electrical equipments.
