Re: [EnergyPlus_Support] Connected Zones

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

This is a good start.  I would also add some cross mixing to transfer air 
between the two zones.  What flow rate to use?  That is very difficult to say.  

Note that windows in EnergyPlus are opaque to infrared (long-wave) radiation 
(see Engineering Reference p. 171, pdf p. 199), so there is no direct radiant 
exchange between surfaces in different zones even when there is an interior 
window.  This should be a small effect if the windowglass is given a high 
emissivity so that is will simply exchange with Zone A on one side, conduct 
through and exchange with Zone B on the other side. 

Also, be sure to use FullInteriorAndExterior solar distribution (in the 
BUILDING object) so that beam solar can be transmitted through the partition 
windows into the adjacent zone.
