Electrical Energy Audit to Achieve Energy Use Efficiency in the Engineering Faculty Building, Hasanuddin University (Unhas) Gowa

Abstract

Energy is a vital need in every aspect of life, increasing population causes energy demand to increase. Energy use in buildings such as offices and universities must be done effectively and efficiently, so as to minimize excessively large electricity bill payments. Therefore, it is necessary to carry out an energy audit to determine the Energy Consumption Intensity (IKE) value in order to obtain an IKE value that meets standards so that effective and efficient energy use is achieved. Energy audit is a technique used to obtain efficiency and calculate the amount of energy consumption in a building using certain methods. This research was conducted in the Electrical and Civil Building at Engineering Faculty, Universitas Hasanuddin. The aim of the research is to determine the value of energy consumption intensity through an energy audit process, as well as finding solutions for saving electrical energy. Based on the research results, it is known that in the initial energy audit, the IKE value produced in the Electrical Building and Civil Building is 233,436 kWh/m²/year. The IKE value is classified as "Wasteful" criteria. Then at the final energy audit stage, the IKE value produced in the Electrical building is 181.19 kWh/m²/Year, and in the Civil building is 175.75 kWh/m²/Year. The IKE value is classified as "Quite Wasteful" criteria. Energy savings can be done in various ways, such as; turning off electronic devices when not in use, changing the type of LED lights, arranging a good room layout, carrying out routine maintenance on the AC, etc.
