Energy management is an activity that must be carried out by a building to save energy; therefore, it is necessary to consider environmentally friendly building construction as a strategy to reduce energy consumption and overall environmental impact. This research was conducted at a food court in a mall for five days with different inverter operation scenarios. On the first and second days, the carbon emission level was high because the system was not yet equipped with an inverter, making energy conversion less efficient. On the third and fourth days, partial use of the inverter resulted in a gradual reduction in carbon emissions along with an increase in energy efficiency up to 20%. Peak efficiency was achieved on the fifth day when the inverter operated at full speed. Although KWH power consumption was higher on the fifth day, optimal electric energy management also successfully reduced carbon emissions to the lowest level of 534 ppm with a power usage of 10.21 kW. The analysis using the Six Sigma method with the help of MATLAB application showed that the operation condition on the fifth day was the optimal scenario in balancing energy use and reducing carbon emissions, reflecting an effective low-carbon electric energy management strategy. © 2025 IEEE.
