Heating/Cooling Balance Issue

Last post

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?

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,

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

Thanks for taking the time to respond!
