Open studio spaces, constructions, thermal zones
So, I mistakenly drew up my commercial building without having much forethought into thermal zones, and constructions. My questions are as follows:
1.a I've drawn up some really large spaces, and need to split them up into separate thermal zones. There are no barriers between the zones in terms of constructions (no walls between these zones), just different RTUs feeding certain areas of the building. Do I need to go into the SketchUp model and physically split the zones as shown in this example: https://www.youtube.com/watch?v=WWu_J... or is there another way to have multiple RTUs within one space.
1.b. Should the surfaces between these spaces (assuming I need to draw new spaces) have "air wall" surface constructions? Since there really isn't any physical walls between these zones (as described above), or is there another methodology to this?
2.a Since I really didn't pay much attention to constructions when building my spaces, I have an enormous amount of unspecified surface constructions, mostly interior walls (although most of them are labelled as exterior walls for some reason (see Q.3.a below). Is there any way I can enter these in without having to manually alter individual surfaces in OS -> spaces -> surfaces tab? For instance, all the interior walls will most likely have the same construction.
3.a A caveat to question 2 above. When creating additional spaces/zones using the youtube tutorial methodology listed above, the walls which should be interior walls, are labelled as exterior walls. Even after running "surface matching" in SketchUp as well as the BCL Surface Matching Measure, most of my interior walls, between spaces, are labelled as outdoor boundaries.
3.b Further to this, since I now have, for instance, 2 spaces with adjoining interior walls, there are technically 2 surfaces that are essentially one wall. Should I enter one of these walls as the actual surface construction and the other wall Adiabatic/AirWall?
