How different are the CBECC-Com prototype models compared to DOE prototype model? I am using CBECC-com prototype (Large office)model and after running the model as-is without any changes, I get an EUI of 15.70 kBtu/hr/ft2. That seems very low compared to the DOE large office prototype model(EUI 60kBtu/hr/ft2). Is it to do with the just the standards alone(Title 24 Vs. ASHRAE)? Am I missing something? Have any of you seen the difference? Can I get some help on this? Thanks
