You have the cooling control set at constant – do you know if the existing building has a sequence of operation to follow? 
  
For a recent  new building which had a VAV air handler with a chilled water coil (water delivered from an aquifer in this case, VFD drives, etc.) I used the below parameters, which appear to have a large effect on your model.

Hi, 
  
I’m trying to model an existing building with a chilled water VAV system.  The chilled water usage is much higher in the winter time than expected.  Is this a common issue?  Does anyone have any suggestions for fixing this?  My files are attached.
