In recent years, extensive research and studies have been focused on energy efficiency with the common target to reduce the energy consumptions against the backdrop of challenging of modem days. Various emerging technologies have been developed to reduce the energy consumptions even though there are still some sectors that are not concerned with the important of the energy management at all. Lighting and air conditioning is a key part of energy use in commercial and industrial sector. In fact, it's verified that lighting and air conditioning plays a very .important role which affecting the profit margin by energy conservation. Major electrical energy utilization in building is affected by lighting. Lighting required approximately 25% energy consumptions in building. Even worst, in commercial business, 70% to 80% of electricity bills are consumed by lighting. Besides, in view of Malaysian context, major uses of electricity consumed by lighting and approximately 17% of national electricity usage utilized by lighting purposes. Both lighting and air-conditioning plays a very important role in increasing the profit margin by energy conservation. Thus, effective energy management has been considered as the main way to reduce energy consumption by lighting and air-conditioning. Energy audit is an effective management tool to reduce cost. Initially, the existing lighting system and air conditioning system in Block C is analyzed in term of total power, energy consumption, and electricity payment per month and per year. Therefore, the project concentrates on energy audit for lighting and air conditioning system in the Institut Kemahiran Malaysia (IKM) Bintulu case study for academic building. Most of the appliances in the IKM Bintulu building use electricity. As the result, several methods of energy saving proposed. The total cost, annual profit, and payback period for each method are also studied. These appliances have label on them stating how much power they used. The unit tariff charged by SESCO (Sarawak Electricity Supply Corporation) will be reviewed and analyzed. The calculation on the energy consumptions were based on the amount of power utilization.
