Abstract

Electrical energy is a very important requirement to support regional government office activities. Excessive energy use can certainly cause energy waste, so to prevent excessive energy use it is necessary to take energy efficiency measurement. Energy Audit is the one method to measure how efficient the energy usage. Based on SNI ISO 50002 : 2018 regarding energy audit guidance, We conduct the energy audit at the one of local government building in Jakarta City. In doing so, the scope and objective of this energy audit project are to review and evaluate the energy consumption 3 years ago particular for electric, cooling and lighting system saving opportunities. The result from this project are the Enpi's value are 184 kWh/m2 per year. it can be indicated that the building inefficient in energy usage. The Power Quality Analyzer showing inefficient from electrical system because the cosh phi value is 0,75 and automatically get the penalty from PLN. The lighting system still in non LED technology. The Cooling system need improvement to make the energy consumption more efficient. There is a Solar pV rooftop potential installation  that could give the contribution in energy saving around 134.963 kWh/Year. All of summary and recommendation that can be proposed in energy saving potential is 244.169 kWh/Year or 53% cost energy saving from existing cost energy consumption.

Abstract

The energy audit is a method for analyzing energy use patterns in a facility and identifying potential efficiency improvement opportunities. In this study, level 2 of the energy audit was conducted at one of Indonesia's fuel terminals. The energy performance indicator (ENPI) was calculated over three years. The ENPI of the fuel terminal increased from 2022 to 2024, indicating that energy consumption per unit of production (kL) rose year by year. The increase from 2022 to 2023 was 27%, while that from 2023 to 2024 was 14%. A higher ENPI value indicates greater energy consumption to produce each kiloliter of product. The implementation of energy conservation opportunities is expected to reduce energy consumption by an average of 5–10% per month, equivalent to approximately 35,784–48,585 kWh per month, and can also reduce CO? emissions by 298.14 TonCO?Eq using an emission factor of 0.83. In order to implement an energy management system, the organization must establish a supporting system, particularly an energy policy that defines the company’s general energy-related policies.
