On the one hand, this may not be seen as the primary intent of this credit, since during the initial build-out of a core and shell building there are not usually any existing tenant improvements (walls, ceilings, etc) to maintain.
On the other hand you might argue that it can be attained in some cases where there are non-structural elements provided by the landlord such as ceiling grids, corridor and core walls, etc, that the tenant is using as-is instead of demolishing or altering them.
Might be a judgement call! Another example of a time when it's good to have a few extra points more than your certification goal in case the reviewer sees it differently.

The one thing that you can usually count on with LEED credits, is following the intent of the credit. You definitely cannot earn the credit if there are zero non-shell, non-structural components. If it is a new CS building, it is highly unlikely that there would be sufficient interior elements to pass the "good faith" test of whether the credit is applicable to the project.

That is my feeling as well, but it would be could if someone could quantifiably "draw the line"...if someone from USGBC could put in a minimum % of area required to qualify (similar to LEED NC MRc1.2).
Right now I would say minimum 50% as in LEED NC...then I'm safe, but that's a bit harsh for a CS developement wanting to certify later spaces under CI.

Hi Jean,
After some more digging in the reference guide, I think I may need to reverse my answer a bit. An example is given in the ref guide "If the ceiling is exposed, both prior to construction and in the final design, include this area". This makes me think that it does not matter what is there to begin with, what matters is whether or not you retain it. If it is an exposed concrete floor at construction, and the project team retains that- then it counts. My apologies on the first response, that was wrong. Based on my re-reading, this project is eligible for a core and shell building, it would just need to retain that existing finish.
