[BLDG-SIM] Gas Penalty for Indirect/Direct Evaporative System (IDEC)

[Michael Tillou]

Xiang,
 
If I had to guess the problem isn't a bug in eQuest but something with how
you have setup the model.  I just went and looked at a couple of old models
from buildings in SLC, UT I did earlier this year with IDEC and I didn't
have any problems with heating penalties.  I just double checked by
simulating several parametric runs just turning the IDEC on/off and my
heating energy was within 1%.  I also got the same results using both eQuest
3.61 and eQuest 3.60.
 
Regards,

Hi Everyone,
 
We are evalulating energy savings from an IDEC system for a LEED office
building with eQUEST, and ran into a huge gas penalty. To maximize the
savings, all supply air passes through the IDEC system. Our conversations
with other modelers indicated many of them had similar problem. I was
wondering if there is a good explanation for this gas consumption increase
and whether there is a right way to simulate the IDEC if the gas penalty is
a bug. Thanks.
