I want to do a rough comparison of the floor area to the door/window area of an apartment-building on an apartment by apartment basis. I've set up a zone scheme, as it can give me both the floor area of the zone, as well as information on windows/doors etc along the outer walls of the zone.
The problem comes from the fact that this comparison I need to do, only should take into account doors and windows that lie in the external walls of the building. When I use the "Door surface area" field, i end up with the surface of all doors on the perimeter of the zone, including the one that leads into the stairwell. Is there any way to, in more detail, define which doors I want to measure the area of?
If I understand the scheduling system at work here "doors surface area" is a property of the zone in question, not the doors themselves? So it is not enough to differentiate the doors, such as through properties, classification or ID. There must also be some way for the zone to recognize these differences in the doors that adjoin it. Is there a way to do this?
