We are having some issues with unmet hours also. Our systems are autosized, so there must be some issue with the autosize routines. We have to identify the
offending zones and make some manual changes to get by. But you should also check your controls, set points, and schedules for errors or ommisions.

Subject: [EnergyPlus_Support] Unmet heating load in Design builder [1 Attachment]
I observed large unmet heating load in designbuilder ~2000. The system is pretty standard VAV with reheat. I don't have this problem with Openstudio.
So I don't know if anyone using designbuilder has this problem before. I attached the E+ file that was generated by DB.
Also, I don't know if there is a way to properly set a VAV to be 100% outdoor air in DB.
Your help is much appreciated.
