Inefficient energy use can lead to waste, which negatively impacts both the economy and the environment. Energy efficiency in dormitories can be achieved through energy audits, an essential evaluation process to identify building energy performance and potential savings in electricity consumption. This study employed field observation method through the collection of building physical data, historical electricity consumption records, and interviews. The Tanah Laut dormitory consists of 16 rooms with 2 floors (± 392 m² per floor). Measurement results show energy consumption of 14.611 kWh/day or 336.128 kWh/month. The supervisor’s room recorded the highest consumption at 16,43 kWh/bulan, while the terrace had the lowest at 3,6 kWh/bulan. The total monthly energy consumption reached 336,128 kWh, with an IKE value of 5.14, categorized as efficient according to the Ministry of Energy and Mineral Resources Regulation No. 13 of 2012. The proposed energy-saving strategies include: (1) no-cost: educating residents on efficient energy use behavior to control the number and duration of appliance usage; and (2) medium-cost: replacing fluorescent lamps with LEDs (potential savings of ±75%) and installing motion sensors in corridors, kitchens, and bathrooms.References
