@shorowit Sadly that there's not a better solution to keep the surface-to-surface mapping information while knowing the handles after merging unit models (and I cannot do it in front, by assigning a surface in another model space as adjacent surface). The only solution I can think of here is to use the indexes after calling model.addObjects. OS source codes specifically call out that the order will be kept, so it's fine for now, but we need to be careful if this is called more than once in the future.
Tried a hundred times and this one seems to be working, still pretty promising!

Great to see some progress! A couple initial questions/thoughts.

Can we simply use count(*) or similar to prevent any detailed inputs? We'll also want a test_validation.rb test that shows these Schematron errors getting hit.

Currently it feels a bit more complicated than I would have expected just because you're operating on the objects of the final merged model, so you have to know which surfaces are linked and what space to attach them to. I wonder if this can be simplified.

The latest a few commit tried to simplify it a bit further (first one makes it working). I removed two methods in the hpxml.rb and only keeps the sameas which returns the fully described object. I stored the adjacent surface ids directly to the OS:Space additional properties, and I stored all the HPXML ids to OS:Surface additional properties. In this way, after merging, I can use OS:Space to find the OS:Surface. It's more straightforward and less coding compared to previous approach. However, the adjacency still happens after merging, I think this execution point is determined in the first place, mainly because that the OS:Surface and the OS:Space is not in the same workspace before merging, so it's not able to create adjacent surface using OS:Space outside the scope. Let me know if you have any thoughts.

One more remaining question related to calling individual dwelling unit (wrote down in case I forgot): Should we enforce the surfaces with full descriptions to be specified in conditioned dwelling units so that they can be called alone? Technically for surfaces connecting two Building elements, users can specify the surface full description in either Building element, which will make the call of running individual dwelling unit error-prone. We can either:

Only allow whole building simulation when sameas is provided, then the surface inputs can be specified in either Building element, or:
Only allow surface full descriptions all in conditioned units, and the user can call building ids of conditioned units to simulate individual dwelling units

Honestly I was implementing assuming the former in the first place, considering how MulTEA uses this feature (and floors are always specified as floors(vs. celing) in MulTEA inputs, so the full descriptions can be in the unconditioned Building element), but I'm fine with the second for more flexibility.

I relaxed this rule to count "sameas" floor also as a ceiling/floor(two lines below), but we have no better knowledge of whether it's a floor or ceiling, or if user only specifies one of them. Let me know if any better thought.

A basement can be a separate Building element, So I added foundation wall here too.
