T he energy audit aims to determine the energy use profile of a building and seek efforts to increase energy use efficiency without reducing the comfort level of the building. The energy audit in this study was conducted at the Directorate General of Corrections Building in the form of an initial electrical energy audit that focused on the lighting system and air conditioning system. The research method used in this study is the method of observation and energy conservation.The audit begins with data collection and processing, then analyzes and calculates the building's IKE value, followed by providing recommendations for energy saving opportunities. The goal to be achieved in this study is to calculate the intensity of electricity consumption in the Directorate General of Corrections building in order to find out how efficient the use of electrical energy is in the Directorate General of Corrections Building, followed by providing recommendations regarding energy saving opportunities. In the initial energy audit, the results of the IKE value were 156 kWh/m2/year, which was included in the fairly efficient category. The search for Energy Saving Opportunities (PHE) in this energy audit began by reducing the operational hours of the air conditioning system and also the lighting system. The IKE value in the Directorate General of Corrections building could reach the efficient category target of 132.84 kWH/m2/year.
