Hello all,

I am trying to rerun a 5-year old PowerDOE model in eQuest.

I was able to get the model to run in eQuest, but a comparison of the PS-E
reports

of the PowerDOE and eQuest versions shows significant differences in end
energy use,

particularly for heating, cooling and ventilation fans. I had to make a
couple of changes

to the INP file before it would run in eQuest without errors, mainly
assigning system

defaults for CHW, HW, and Baseboard loops, and assigning a value for Zone
Reheat Delta T

to allow for reheat in VAV boxes. Other than that, nothing was changed.

Does anyone have any suggestions as to why the energy use may have changed
so much

going from PowerDOE to eQuest with virtually the same INP file? Are the
load calculations

or default equipment performances significantly different between eQuest and
PowerDOE?

Any input would be much appreciated.

Thanks,

Rob Bialobrzeski
