| 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%). |
