[EnergyPlus_Support] Re: [Equest-users] equest and energy plus outputs



I was involved in a two year project 2005-2007 to convert the Calif. 
Energy Commission's Title-24 certification suite of building tests from 
DOE-2.1E to EnergyPlus.  There are some areas where it's difficult to 
get comparable inputs due to differences or limitations in the models. 
The differences between the two programs varied a lot depending on the 
building, weather, and HVAC system. For the CEC certification suite of 
160 runs, cooling results were more consistent, within 10% in most 
cases, with EnergyPlus almost always on the high side; for heating, the 
differences were much greater, sometimes with EnergyPlus being 40-60% 
lower than DOE-2.1E.  I have a 120-page report on this comparison, but 
haven't bothered to put it on the Web.
