Lowering Covid-19 cases globally and nationally provides a positive indication of economic growth, especially in Batam City, Indonesia. This condition is also followed by increased electrical energy consumption, particularly in residential houses. This paper presents an electrical energy audit process of a residential house using the IKE (Energy Consumption Intensity) parameter. The audit was conducted in a home with a building area of 226 m2 and an electrical capacity of 4400 VA. The result shows that the total electricity consumption of such a house is 1,266.34 kWh per month, to which the air-conditioning system contributed the most prominent electricity consumption of the whole facilities in the house. Providentially, the score of IKE is less than 8.5, which means such a residential house is categorized as very efficient energy consumption. Furthermore, the self-evaluating checklist technique has carried out to find the main factor that affects the electricity consumption of the air-conditioning system. Regarding the highest rating score on the self-evaluating checklist of air conditioning systems, the ceiling has a score of 77.5%. This result means that the ceiling needs to be evaluated to reduce the heat load of the house, which in turn reduces the electrical energy consumption of the air conditioning system. Finally, this work can use as an initial audit framework for assessing electrical energy consumption in residential houses in Indonesia. [ABSTRACT FROM AUTHOR]
