Re: [EnergyPlus_Support] Zoning for VAV application

["Michael J. Witte" <mjwitte@xxxxxxxx>]

In EnergyPlus, a single VAV terminal unit serves a single thermal zone (ZONE 
object and associated surfaces, etc.).  But you can combine multiple rooms into 
a single thermal zone, and the rooms do not necessarily need to be contiguous.  
In the case of your model, you could simply change the zone names for the 
surfaces and internal gains to combine several rooms into a single thermal 
zone.  

Note, however, that solar gains, internal gains, and radiant interchange will 
be distributed among all surfaces associated with the same thermal zone, even 
if they may not actually "see" each other geometrically.  So, this should only 
be done for rooms with similar characteristics.
