[Bldg-sim] Equest 3.6 Simulation of Campus Chilled Water Meter

[Brett Krug, PE]

I have been struggling with an issue on a large campus energy model.  I am
trying to model the chilled water system, which is a campus system simply as
metered energy.  I have basically indicated a chilled water meter of the
chilled water loop.  My problem is that when I simply replace a chiller with
the chilled water meter and re-run the model my space cooling energy
consumption goes up dramatically (over 2 times).  I have been working on
this for a long time, and cannot seem to figure out what is causing the
chilled water meter to (virtually) create additional chilled water energy
consumption on the chilled water loop.

Does anyone have familiarity with this issue?

I had a similar problem some time ago.  The issue was resolved with 
minimum data loss by opening a new, blank file and then importing the 
.inp file from the original.  I lost my Wizard data but was beyond that 
in the project. 

Good luck!
