Keywords: Energy efficiency, energy consumption intensity, lighting, air conditioning, energy audit

This study aims to analyze the air conditioning and lighting systems to support energy efficiency at the office of PT Jorong Barutama Greston (PT JBG), a coal mining company located in Tanah Laut Regency, South Kalimantan. The methods employed include an initial energy audit through the collection of electricity consumption data over the period of April–September 2025, lighting intensitymeasurements,EnergyConsumptionIntensity(ECI)analysis,application of the 6-Month Simple Moving Average (SMA-6) method, as well as interviews and questionnaires administered to the HRD and HR departments to assess employees'levelofunderstandingandawarenessregardingenergyefficiency.The results indicate that the total energy consumption of the building over six months reached 281,996 kWh with an average ECI of 130.54 kWh/m²/year, classified as moderately efficient; however, this condition is at risk of deteriorating as the ECI spiked sharply to 155.07 kWh/m²in September, fallinginto the wasteful category. Thetwolargestcontributorstoenergyconsumptionarethelightingsystem —with 23 LED units operating continuously for 24 hours without scheduling and most rooms failing to meet SNI 6197:2020 standards — and the VAC system, with 12 airconditioningunitsrecordinganECIof15.43kWh/m²permonth,exceedingthe efficiency standard of ≤10 kWh/m². From a human resource perspective, employees'understandingatthepolicylevelisreasonablygood;however,thedaily practice of energy-saving culture remains suboptimal due to the absence of automatic sensors, limited energy-saving incentives, and insufficient employee involvementin decision-making related toworkplaceenvironmentalconditions. If all efficiency recommendations are consistently implemented, PT JBG has the potential to save approximately 20–25% of total consumption, equivalent to 56,000–70,000kWhperyear,withoutrequiringlarge-scaleequipmentreplacement investments.
