Energy Conservation and Energy Audit as an Energy Saving Effort at MSTP UNDIP (case study of MSTP Undip Jepara)

Conservation and energy saving audits on the consumer side are carried out to reduce the rate of energy use so that energy is not wasted. The MSTP Undip Jepara building was chosen as the object of the audit due to the absence of an energy audit report as a form of energy saving plan. Energy audits are carried out using the energy consumption intensity method to determine the efficiency level of the building based on the Minister of Energy and Mineral Resources Regulation No. 13 of 2012 and the significant energy users method to determine the distribution of energy consumption on installed equipment so that energy saving opportunities can be saved. Based on the calculation results, the MSTP Building is in the category of efficient energy consumption with the energy consumption intensity of air-conditioned and non air-conditioned buildings in 2021 with value 9.0 kWh/m2/month and 4.9 kWh/m2/month. Energy saving opportunities savings in the no/low cost category, the resulting savings are Rp. 31,963,190, medium cost Rp. 18,490,311, and high cost Rp. 582,503. Savings include setting air-conditioned temperature, reducing air-conditioned operating hours, replacing TL Neon and Spiral lamps with LEDs, as well as replacing conventional PCs with All-in-one PCs
