Economic analysis of using the energy management system in the building with the approach of reducing cost and energy consumption

Energy management in the construction industry is one of the important issues in the field of construction industry, which can reduce the cost of energy and pollution. Considering that a significant part of the share of energy consumption among the consumer sectors is related to the domestic and commercial sectors and this share continues to increase, the need for research in energy consumption management and the investigation of effective indicators in the construction industry. It seems vital in order to optimize energy consumption. In this research, after examining the society and the statistical sample, data collection has been done to examine effective criteria and options related to energy consumption management. The purpose of this research is to estimate the potential of reducing energy consumption and evaluate its financial and economic benefits in the building through energy audit and identifying strategies to reduce energy consumption. For this purpose, the amount of energy consumption in the typical 6 floor building with 100 square meters of floor area in Jakarta in 2023 was audited using the energy economic evaluation software, and then action strategies to reduce energy consumption have been introduced and their potential to save energy consumption as well as the resulting financial benefits have been evaluated. In the next step, the energy costs and the capital return period were calculated once in the sample building model and again in the case where the energy management system was simulated on that building. The results show that by using energy management solutions (economic construction and facilities), energy consumption is reduced by 3.20%. Also, considering the current price of fuel and the 5-year time period, according to the inflation rate of 2% per year for the return of capital obtained from the economic analysis, additional initial costs will be compensated by applying the proposed policies.
