Audit and Monitoring on Electrical Energy Consumption at Soedarsono Hospital, Pasuruan City

An energy audit is a proactive measure aimed at reducing electricity consumption without compromising the comfort of building occupants. The energy audit was conducted at RSUD Soedarsono Kota Pasuruan, where various energy-saving opportunities were identified to achieve energy efficiency. The methodology employed in the preliminary energy consumption audit involved the collection and compilation of data on energy usage at RSUD Soedarsono Pasuruan. The required data included technical architectural drawings from the archives of RSUD Soedarsono Kota Pasuruan, encompassing blueprints of the architecture, lighting design for the entire building, installed electrical diagrams, annual electricity expenditures, and the building's location. The hospital building has an installed capacity of 500 kVA, approximately 0.5 MW, and an additional backup power of 1.5 MW from three generators. The installed loads in the hospital consist of a lighting system with a capacity of 106.678 kW and an air conditioning system with a capacity of 871.2415 kW. Given the energy-intensive nature of RSUD Soedarsono Kota Pasuruan's building criteria for the years 2022-2023, energy-saving efforts are required to meet the energy-intensive criteria with an Intensity of Energy Consumption (IKE) ranging from 50 to 95 kWh/m2/year. This necessitates reducing electricity consumption to at least 877.374,731 kWh per year. The audit results indicate that by implementing the energy-saving opportunities recommended by the auditor, the total electricity energy savings amount to 375.654,97 kWh per year. Furthermore, the current Intensity of Energy Consumption (IKE) of 26.789 kWh/m2/year demonstrates a highly efficient level. If these measures are implemented, the forward projection reveals an energy saving potential of 1.431.975,0288 kWh per year, equivalent to a 10% reduction in the average total Power Consumption over one year at the hospital.
