<p class=MsoNormal style='margin-bottom:12.0pt'>I wonder if the electric loads
are associated with pumps for your chilled water system? I'd Google eQUEST
reports to see if Marlin or others have written about this. I suspect that it's
just an auxiliary load associated with moving the chilled water, or cooling
tower fans, that you needn't worry about.<br>
<br>
Let us know what you find out.<br>

STANDBY, DEMAND-ONLY, SNAP.<br>
With STANDBY you may see electrical consumption when no system has a load.<br>

<p class=MsoNormal style='margin-bottom:6.0pt'>Hi All,<br>
<br>
Have you happened to meet problem with strange cooling in winter when you
choose chiller as cooling source?<br>
<br>
I have a typical 2-storey office building (with no extraordinary internal
cooling load) modelled using eQuest. Whenever I choose "chilled water
coils" as cooling source, some cooling energy appears in the
"Electric Consumption" graph for Jan and Feb, although the SS-I
report indicates no sensible or latent cooling energy in these two months. When
I change the cooling source into "DX Coils", the cooling energy in
winter simply disappeared.<br>
<br>
Attempting to fix the problem, in the "air-side system" window under
wizard mode, all I used are default values to avoid wrong inputs, and I chose
"no heating" in winter, but the problem still exist.<br>
<br>
This is a LEED project approaching deadline. If anyone could help me out, that
would be greatly appreciated.<br>
<br>
Thanks,<br>
Rick, LEED AP<br>
