Scenarios to Reduce Electricity Consumption and CO2 Emission at Terminal 3 Soekarno-Hatta International Airport

AbstractElectricity consumption in airport terminal buildings can be identified via Low Voltage Main Distribution Panel (LVMDP) which each of them serves individual distribution block. Total electricity consumption based on distribution blocks does not describe operational characteristics of building systems. Utilization of building energy performance simulation software offers solution by providing electricity consumption data based on building systems. This research applied the method in simulating energy consumption and CO2 emission in Terminal 3 Soekarno-Hatta International Airport. Simulation result shows that total electricity consumption of Terminal 3 is 27700.107 GJ or 7.694 MWh per year, with 86.59% of that is consumed by HVAC system, 9.33% used by lighting system, 2.41% used by electricity equipment, and 1.76% consumed by transportation system. In order to achieve CO2 emission reduction, three scenarios are simulated in this research, i.e. increasing temperature setpoint, AHU (Air Handling Unit) rescheduling, and window films replacement. Increasing temperature setpoint could reduce 247.179 ton of CO2 emission per year. Increasing temperature combined with AHU rescheduling could reduce 286.611 ton of CO2 emission per year. Window film replacement combined with increasing temperature setpoint and AHU rescheduling could reduce 289.966 ton of CO2 emission per year
