I made models with different measures separately in SketchUp environment. For orientation difference I am just rotating the models.

When I pointed the window side of a model to south, east and west, everything is fine, when I pointed it to north the error occurs. The error does not occur with the same model pointed to north where the windows are on larger side of a model.

This model do not work with windows pointed to north.

This model work with windows pointed in every main direction (E, W, N, S).

Is it something with the small amount of light coming in the room? I am using blinds. (Location is Ljubljana - Slovenia - central Europe).

This is not an answer, I just juse this to put some pictures in.
