Re: [EnergyPlus_Support] Zones in Energyplus

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

The presence of interior walls will affect both the radiant exchange and the 
thermal mass of the zones.  If these walls do not exist in the building, then 
it is appropriate to model you zones without them.  You should consider adding 
internal mass objects to each zone to account for the mass of furniture and 
cubicle partitions if present.  Warnings from EnergyPlus are intended to point 
out something unusual so the user does not omit something by mistake.  Severe 
errors indicate that there may be a problem with the results.  If you just get 
warnings in this case, then you can ignore them.
