Recently, increasing energy consumption and CO2 emissions buildings and construction together are accounted globally for 36% and 37%, respectively. This situation implies that buildings consume over one-third of energy demand and emitter CO2 globally. Hence, energy-efficient practices were applied in green building certification to reduce energy consumption and CO2 emission. Each green building certification follows the energy baseline created to take a step further for better future equipped energy end-use. This research objective explains the comparison of different energy baselines referring to GBCI (Green Building Council Indonesia) and ASHRAE standards. Eight buildings using different energy baselines were observed in this research. By integrating energy-efficient practices in green building certification, three energy savings methods were used to calculate different energy baselines, specifically EnergyPlus simulation, worksheet calculation, and EDGE simulation. Through the energy savings method, thus outcome energy savings estimate was obtained. The energy savings estimate in the boxplot graph showed GBCI baseline results in huge savings compared to ASHRAE baseline. © Published under licence by IOP Publishing Ltd.
