Re: [EnergyPlus_Support] single zone

My apologies for the delayed response.

Yes, one large VAV box serving the combined thermal zone is the right approach. 
 If you know the flow rates of the individual VAV boxes, sum them up.  If you 
are autosizing, the loads of the larger thermal zone will result in a VAV box 
sized to meet the load.
