I'm struggling with EcoDesigner. I've made zones that I've connected to thermal zones. The problem I'm having is that parts of the slab between the stories for some reason are marked as exterior. The parts are those that have interior walls below or above, and I can't figure out how to fix this.
It is hard to tell from the screenshot, but I assume that above the interior walls there are zones? If that's the case, when above/below a zone, if there is no zone (in this case the interior walls take the space), EcoDesigner marks it as exterior. But this "exterior part" is negligible for the entire building.
