Abstract

Electrical energy is one of the basic human needs in carrying out various activities or daily activities, especially in office buildings such as office buildings of state higher education institutions, namely the Sumatra Institute of Technology (ITERA). Office buildings are the third highest consumer of electrical energy after shopping centers and hotels. The high demand for electrical energy requires the user sector to make efficiency in energy use. Before making efficiency, it is necessary to know the profile of electrical energy consumption including energy consumption intensity (ECI) and significant energy users. Therefore, in this study, an analysis of electrical energy consumption in each ITERA office building was carried out, through observation and interviews according to SNI / ISO 50002: 2018 energy audit procedures. The results obtained show that the total energy use of the 6 largest buildings (A, B, C, D, E, and F) in May 2023 is 144768 kWh and from the calculation of the ECI value is in the very efficient category (7.44 kWh/m2/month). From 6 existing buildings, there are 3 buildings that are very efficient, 1 building is efficient, and 2 buildings are quite efficient. Then, significant energy users were found by 83% in building C AC. Recommendations for saving energy in the effort of energy conservation and efficiency that can be done include, making changes in habits / patterns of use of electrical energy user equipment, especially in air conditioners and dispensers, so as to save electricity 2-21%, and retrofitting refrigerant AC types of split ducts and cassettes that still use R-22 with MC-22 which can save electricity 15-25%.

Abstract

Electricity plays a crucial role in the operations of companies and offices, as highlighted in the 2022 data from the Ministry of Energy and Mineral Resources. The commercial sector recorded an energy usage of 49.65 million BOE (Barrel Oil Equivalent) and 68.891 GWh of electricity consumption. Excessive use of electrical equipment leads to wastage, resulting in higher electricity bills. Thus, there is a need for an efficient system in both lighting and other areas, with efforts focused on enhancing energy efficiency through conservation.This Final Project aims to determine and analyze Energy Consumption Intensity (IKE) values, lighting systems, and identify opportunities for electricity consumption savings at the PT. X Lampung Office Building. The research method involves an initial energy audit and brief measurements on the lighting system. Results indicate that, out of 13 rooms on all three floors, only 5 meet the standards. The analysis identifies opportunities for electricity consumption savings, with a no-cost method at 8.1% and a low-cost method at 9.1%. These findings are expected to serve as recommendations for identifying energy-saving opportunities in Indonesian office buildings.
