MANAJEMEN ENERGI LISTRIK PADA FASILITAS PUBLIK MILIK PEMERINTAH

Rumah sakit merupakan sektor suatu bangunan dengan kebutuhan energi besar. Seperti penggunaan peralatan penerangan (lampu) dan pendingin (air conditioner). Untuk meningkatkan efisiensi penggunaan energi dirumah sakit, perlu dilakukan perhitungan audit energi atau konservasi, kemudian mencari alternatif peluang untuk penghematannya. Dalam menentukan jumlah lampu dan kapasitas daya (PK) AC (air conditioner) pada suatu ruangan harus berdasarkan standar lux dan BTU/hr yang telah ditentukan. Berdasarkan hasil perhitungan audit energi awal diperoleh total pemakaian energi listrik sebelum konservasi 11.942,8 kWh/bulan, biaya tagihan listrik Rp. 17.042.304 dan intensitas konsumsi energi listrik sebesar 5,13 kWh/m2 atau 61,56 kWh/m2/tahun. Hasil audit energi rinci peluang hemat energi pada peralatan pendingin dan penerangan diperoleh total pemakaian energi sebelum konservasi 9.570 kWh/bulan, setelah konservasi 8.501 kWh/bulan dengan biaya penghematan energi Rp. 1.525.643. Apabila dilakukan pergantian peralatan pendingin ac (air conditioning) diperoleh biaya peluang hemat energi (PHE) untuk peralatan ac sebesar Rp. 590.778. Sedangkan, nilai intensitas konsumsi energi setelah konservasi 4,76 kWh/m2/bulan atau 57,12 kWh/m2/tahunThe hospital is a building sector with huge energy needs. As the use of lighting equipment (lighting) and cooling (air conditioner). Operating for time improve the efficiency of energy use in the hospital, need to do the calculation of the energy audit or conservation, then look for alternative opportunities for savings. In determining the amount of light and power capacity (PK) AC (air conditioner) in a room should be based on the standard lux and BTU / hr predetermined. Based on the results of the calculation of the initial energy audit obtained by the total electrical energy consumption before conservation 11942.8 kWh / month, the cost of electricity bills Rp. 17,042,304 and intensity of the electrical energy consumption of 5.13 kWh/ m2/year or 61.56 kWh/m2/year. The results of a detailed energy audit energy-saving opportunities in cooling equipment (air conditioning) and lighting (lamps) are obtained prior to the conservation of total energy consumption 9570 kWh/month, after conservation of 8501 kWh/month with energy cost savings of Rp. 1525643. If the replacement is done ac cooling equipment (air conditioning) obtainable cost energy saving opportunities for ac equipment amounting to Rp. 590 778. Meanwhile, the value of the intensity of energy consumption after conservation 4.76 kWh /m2/ month or 57.12 kWh/m2/year
