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.</FONT></SPAN></DIV>

[BLDG-SIM] Gas Penalty for Indirect/Direct Evaporative System
(IDEC)<BR></FONT><BR></DIV>
<DIV></DIV>
<DIV>Hi Everyone,</DIV>
<DIV> </DIV>
<DIV>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. </DIV>
