Re: [EnergyPlus_Support] AirFlow Window on a Zone

[Rob Hitchcock <RJHitchcock@xxxxxxx>]

There are two approaches to modeling double facades in EnergyPlus.  One 
approach uses an airflow window (modeled using WindowGapAirflowControl) 
to represent the double façade zone.  A second approach models the 
double façade zone as a separate zone with glazed exterior and interior 
walls.  The second approach uses standard window constructions on the 
exterior façade that can include a shade/blind on the outside, inside, 
or between glazing layers.  This exterior window can also be an airflow 
window.  The interior wall can contain standard window constructions, 
but without any shading layer, and cannot be an airflow window.  The 
Airflow Network model can be used to simulate the effects of airflow 
within this exterior double-façade zone and between the outdoors and 
adjacent zones whether or not the zone is mechanically conditioned.
