I am assigning custom interior wall. Is there an easier way to assign the construction to the "Outside Boundary Condition Object" since it is the same wall type?

I am assigning custom construction types to interior surfaces. Is there an easier way to assign the construction to the outside boundary condition object rather than doing it manually (they both have the same construction material)?

If I'm understanding correctly, you are using a default construction for most of your interior wall constructions, but you some interior wall constructions that you want to hard assign a custom construction for. Looking at the screenshots below. Initially all of the constructions were inherited from construction sets so they showed up as "green".

I then dragged a custom construction to the wall in "Perimeter_ZN2" that happens to be adjacent to a wall in "Perimeter_ZN1". Notice how when I did that, the construction in "Perimeter_ZN1" changed it's construction but still shows as inherited. I think that is the behavior you are looking for so you don't have to assign the construction twice.

As a side note, if there is a logic to where you area adding custom construction you have some additional options.

  1. If you want to apply a custom interior wall to all interior walls on a specific building story, you can custom construction set with only interior wall construction and assign it to a specific building story object.
  2. If you have a specific space type like X-ray that you want to assign a custom wall construction to you can create a custom construction set as described in option 1 and assign it to a specific space type used in your model.
  3. Lastly you can also assign a custom construction set to a specific space.

The approach described above is typically used for attics, and when modeling plenum zones or raised floors as their own thermal zones.

Yes, this is exactly the behavior I am looking for so I don't have to assign the construction twice. Is there a setting that I have to turn on to do this? When I hard assign a construction, only one of the surface changes. The corresponding "outside boundary condition object" does not change.

No setting for this, try first clearing out all of your hard assigned constructions for each surface. If you have hard assigned a construction it will override any kind of inheritance.
