OMPARISON OF ENERGYPLUS AND DOE-2 DETAILED WINDOWHEAT TRANSFER MODELS
Neal Kruis, Chuck Booten, Craig Christensen
Two commonly used building energy simulation en- gines, EnergyPlus and DOE-2, can differ significantly in their calculations of window heating load. In this paper, the authors identify the issues in the window heat transfer algorithms used in detailed window models, and provide suggested changes to make the calculations more accu- rate. We estimate that up to 82% of the observed differ- ences can be resolved through the suggested changes. The methodology employed for this investigation in- volved programming the algorithms from the respective simulation engines in the Engineering Equation Solver (EES) so that the impact of each proposed change could be investigated and quantified independently.
