Re: [EnergyPlus_Support] how to describe the air partition between perimeter zone and interior zone

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

My apologies for the slow response.

This is a difficult feature to model.  Material:Air will not transmit light, it 
is simply a resistive layer.

1.  A window subsurface is required to transmit solar and visible light from 
the perimeter zone to the interior zone.

2.  If the two zones will generally be controlled to the same temperature, then 
air exhange between the perimeter and interior can be neglected.  If a 
significant temperature difference is expected, then MIXING, CROSS MIXING, or 
AIRFLOWNETWORK:* objects are required to model the air exchange.

3.  There is currently no method for modeling radiant exchange between surfaces 
in different zones.
