Help regarding Double-Skin Facades

Postby mutu » Thu Mar 19, 2015 11:50 pm

Hi. My name is André and I'm trying to simulate a double skin facade in DesignBuilder 3.4.
I had a look and found a template for this kind of facade. While I was exploring that model, I ran a CFD simulation that shown no air circulation between the cavity and the occupied space.

Then I tried recreating this kind of element in a model that I created from scratch, by drawing two different block and placing them together. Then I ran the CFD simulation to see if the airflow was similar, but found out that there was a trade of air between the cavity and the occupied space, trough the interior window.

I've tried everything, but I didn't come up with a solution that made the cavity airtight like it is on the default template.

If someone could help me, I would be really grateful.
