[EnergyPlus_Support] modeling atrium with airflow network



dear Energy Plus Forum and users,

I am modeling an atrium with significant height.
Scope of the work it is to study ventilation strategies.

I have looked at airflow network and I understand that the results
will be in most of the cases very approximative.

I am wondering what is your experience in dividing the space in to
stacked thermal zones.

In my case I thought that I could divide the space into 4 thermal
zones (every 10 feet) and connect this with "big" cracks.

To allow the model accounting the influence of the solar radiation
that heat the floor, I was thinking about putting virtual horintal
windows between the zones.

In this case, is the radiation considered diffuse after the first zone
(and not direct)?

I would greatly apprecia if different users would like to share their
experience in modeling atria.

thank so much!
Regards

Emanuele
