[Bldg-sim] EQUEST QUESTION

[Morgan Heater]

I would take a look at your unmet load hours in the perimeter spaces.  If
they're high it's likely that you have a heating air flow rate or supply
air temperature issue.

Subject: [Bldg-sim] EQUEST QUESTION

I am trying to learn E-Quest and I am trying to model a building that I 
have already modeled with Energy Pro.  The gas usage from E-Quest is 
very very low compared to both actual and Energy Pro.  It is a hot water 
reheat VAV system with a boiler and a water cooled condenser.  The 
actual gas use is 17891 Therms, from the bills.  Energy Pro predicts 
17600 Therms.  E-Quest predicts 580 Therms.  This makes no sense to me, 
but it is clearly my error.  I have gone over the inputs several times.

Is there anything that occurs to anybody that would make gas usage that 
far off?

Electrical from E-Quest is 453 MWh.  Electrical from Energy Pro is 422 
MWh.  Electrical actual is 543 MWh.  The building has lots of 
unaccounted-for process equipment, so I'm not so worried about being low 
on electrical.  It's not too far off.  But the gas use is just way too 
low.  Hot water is showing up at 3 Therms a month.


This is the first model I have done with E-Quest, so I apologize for 
even asking.  It's obviously something stupid that I have done.
