ventilation - envelope

Gents,
I am simulating a room to understand possible stategy of natural ventilation. This room is 14' tall.
I am trying to have different facade layout to be compared.

But I have a couple of issues:

1)If I change the property of a single window (in this case the operation)every window changes its property, instead I would like to have operable windows (100% area open) and fix windows (0% glazing area open)
2)considering the space height (14') would be better to insert a temperature gradient?

Thanks a lot.
Best Regards

Emanuele

Gents,

I think my previous question was not clear..

I would like to study the impact of natural ventilation for a small room.

The west facade has three windows.

How can I model different windows which are in the same surface?

I would like to have the bottom and the top windows operable and the one in between fixed.

Any help would be greatly appreciated!!

Gents,

this is the image of the case described in previous email, I am wondering if the position of the operable windows could significantly modified the airflow network calculations defining two nodes with different height and pressure, or if probably the only matter in this case in the area of the operable window being the zone with just one temperature.

Thank so much for every possible suggestion.

Three blocks one on top of the other to create three zones, one zone for each horizontal slice containing each window type. Merge the three zones together by drawing holes in the floors and set the 'Merge zones connected by holes' advanced model option. Now you should be able to set the window type for the three separate surfaces.

A DB user in Canada employed this technique recently with success.
