Electrical energy audit and potential energy saving measures for commercial building
description Electrical energy audit is an examination of the energy consumption of the equipment or system to ensure that energy is being used efficiently. It acts as a systematic assessment of the baseline energy consumption efficiency within a facility, followed by identification of energy efficiency improvement opportunities and cost-saving measures that can be implemented to ensure the efficient energy consumption in any building. The electrical energy audit has gained attention across all energy sectors such as residential, commercial, and industrial since energy consumption gives immediate impact on costs considerable and impact on environmental sustainability. Due to problem related to energy management and energy efficiency such as regulation imposed, cost and environmental factor, the electrical energy audit currently has been found as one of the methods that can ensure the sustainability of energy in the future since energy audit activities are able to determine suitable steps and precaution to be undertaken to use energy efficiently.

The main purpose of this study is to evaluate the electrical energy consumption focused on commercial building that will contribute to the framework of potential energy saving measure for future implementation. Therefore, three objectives were focused on which are to evaluate the existing energy management practice of a commercial building, identify historical and present energy usage pattern of the building and proposed Energy Conservation Measures (ECMs) by evaluating the cost analysis for each ECMs proposed.
