Error in aperture for atrium modelling

I am getting the following error:

  1. ** Severe ** GetSurfaceData: Zone ATRIUMLVL6.1_23E78B1D has only one floor, wall or roof, and this surface has a window.

These are due to the apertures placed on my atrium:

the atrium is modelled by floor, solving the adjacency on the floor to create air boundaries, and solving adjacency on the interior walls for them to also become air walls.:


When I place any apertures on the outside of the atrium, the energy model doesn’t work:

If I completely remove the windows from the atrium the model is working fine. the problem seems to be the airwalls created for each floor of the atrium.

Again, I’m not sure what I am doing wrong…
