Re: [EnergyPlus_Support] how to simulate atrium and its adjacent offices

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

Sorry I somehow repeated the question instead of sending an answer.  Let's try 
this again . . .

1.  Zones do not necessarily require a complet enclosure.  If you want sunlight 
and heat to be transferred between the atrium zone and the office zones, then 
you will need inter-zone walls and windows to model that transfer.  Yes, the 
inter-zone walls and windows are each described twice, once for each zone, 
facing in opposite directions.  It is critical to get the facing directions 
correct, or the window will not see sunlight.

2.  I have no advice to offer here.  Perhaps someone else does.
