 Abstract
The purpose of this study is to compare two building energy simulation programs'(EnergyPlus and eQuest) heating/cooling load, and to find the differences by analyzing algorithm, input method and default input parameters based on the ASHRAE Standard 140-Case600. EnergyPlus calculates the inside surface temperatures by solving the heat balance, but eQuest assumes that the inside surface temperature of a thermal zone is equal to the zone air temperature. This result in zone air temperature difference( average) is due to occurred load differences. Change of U-value of vertical surface causes as 7~8 % of the heating load difference and 25~26 % of the cooling load difference. The result of changed SHGC is similar. But the result from infiltration shows a little different tendency(The heating load differences decrease from 7 % to -16 % and cooling load differences increase from -26 % to -19 %). All of these differences are caused by algorithm discrepancies of convection coefficients, actual air change rate and solar transmittance.
