Manipulating them may still be easier than attempting to
simulate it with airflow network.

Obviously, not my area of expertise.

Yes, they are mechanically ventilated but the problem is this:
For triple-glazing the airflow is assumed to be between the two inner glass layers. In my case the ventilated cavity is between the  Single Exterior Glazing and interior double glazing

Okay, have you looked at Airflow windows?  I can't remember if they are mechanically ventilated or not.

Our Airflow network specialist is gone right now -- he will be back next week. 

You just sent the same message to the group again -- except this time with a subject?

Have you looked at:

SurfaceProperty:ExteriorNaturalVentedCavity

and that is not suited to your purpose?

Hi,we have a project where want to simulate a corridor double skin facades.

The layers of the facade are described below:

Single Exterior Glazing - 110mm air cavity mechanically ventilated with Venetian blinds - double interior glazing.

I model double skin facade as a zone. For each floors I create a zone to represent the ventilated cavity. The width of the zone is 110mm.

Is right to model in this way? Can airflow network simulate mechanical ventilation ???

which algorithm to use for the inner surface of cavity?
