Abstract

The issues and limitations of the current prescriptive domestic building energy code compliance, or EPI was addressed. In order to convert it into being performance-based, a global sensitivity analysis, Sobol was used. For this purpose, a medium office building developed by US DOE was selected. The Sobol sensitivity indices per design variables were substituted for weights (a) and (b) to calculate a new EPI. Based on the comparison between the new EPI, ECO2 calculation and EnergyPlus simulation results, it was found that the new EPI becomes more proportional to Energy Use Intensity (EUI) calculated from EnergyPlus (R2 = 89.3%).
