Re: [EnergyPlus_Support] Voids on exterior walls

Airflow is nto explicitly related to geometry except through some of the AirflowNetwork object, which use windows or virtual geometry. To move air (air heat balance energy) between zones or outside, you need to specify exactly how it will move, there are no objects that automatically have airflow associated with them as in the real world.

Try a simple Ventilation object first, there is a wind sensitivity paramter available there. The ventilation object is associated with a zone, not geometry. For more accurate calcs, use AirflowNetwork. There are alot of example files to draw from.

Subject: [EnergyPlus_Support] Voids on exterior walls

Hello,

Does anyone know how can I simulate a void in an exterior wall in
order to have zone air flow directly influenced by the wind speed in
my building using natural ventilation.

The method described to insert a void between 2 zones don't seems
appropriate to me.

Do I have to insert an AIRFLOWNETWORK:MULTIZONE:SURFACE for each of
them ? (there's a lot...)
or can I transform the voids into windows and insert a
AirflowNetwork:Multizone:Zone ? and in this case, do I have to add an
AirflowNetwork:Multizone:Site Wind Conditions ?

Thanks a lot
