[Equest-users] Heating/Cooling Balance Issue

There is a huge disparity between heating and cooling loads (3-4% Cooling/42% Heating).

Thanks for taking the time to respond!

Hi David,
How are the results different from what you are expecting? I don't see anything too unusual but I am not as familiar with SLC loads as you are.
One comment I have is that you have all constant-volume PSZ systems, one of which has 16 zones assigned to it. Without VAV and/or zonal reheat, you are getting many unmet hours in your zones. I would focus there.
Regards,
~Bill

I will give much praise to the person who can figure out why I have such an imbalance in the heating and cooling loads for the attached ASHRAE 90.1 2010 baseline model. I've been troubleshooting the model for a few days now. I'm sure it's something completely obvious, and I'll be quite embarrassed by the solution.

Anyone up for the challenge?
