RE: [EnergyPlus_Support] AFN How to Simulate Hung-Windows?

Tobias:

The AirflowNetwork model does not support single side ventilation. Please
let us know if you find a good network model to simulate two-way flows at a
single opening.

Hope this helps.

Subject: [EnergyPlus_Support] AFN How to Simulate Hung-Windows?

Hello,

I couldn't find how to describe Hung-Windows (top/bottom/side) in the AFN -
Model. May be the effective Area would be a way for cross ventilation, but
how to deal with bidirectional single sided ventilation? I plan to simulate
the ventilation rates according to an opening angle of hung windows.
Variables i could use (probably together with EMS) are the discharge
coefficient, the window hight, the window width and the opening factor. I
think for a controlled, bidirectional flow the detailed opening model should
be best. Do you have any recommendations how to model or some literature
describing the problem?

Thank you,
Tobias
