We are working on food production facility and offices. The offices will be in the first two floors of an historic building that the developer is renovating as part of the project. The food production facility will consist of a single story addition to the historic building that has a much larger footprint - more than two times. The C&S of the food production facility is basically build to suit and then handed over to the food producer (our client) to develop the TI. I have two questions:
1) Is the TI eligible for MRc1.2 at all? I know the developer would not be eligible for building reuse credits because the production facility addition is much larger than the historic building. Technically, they are moving into an existing facility and building out the interiors. Practically, they caused the addition to be built. I find no eligibility requirements in the CI credit language but noticed that LEED User had posted the eligibility calculator for LEED NC as a documentation tool.
2) Assuming the tenant is eligible on a technicality, what does the tenent get to count as reused? The developer is building no inside walls and the tenant will be "reusing" the interior surface of all the walls. This builds on a question already in forum where Tristan indicated a tenant could count the interior surface of party walls - which we have a few of - but wasn't explicit about exterior walls.
This is an interesting situation that any tenant moving into a new building, particularly build to suit would encounter so I am curious as to the forum's thoughts.

Elizabeth, you raise a good point. That eligibility thing is not relevant for the interior reuse credit or NC or CI. I have removed it from this page.Honestly, I would defer to greater experts on how a CI project should deal with calculating reuse in a situation like this.

Correct, the MRc1 eligibility calculator is intended for NC MRc1.1, structural elements, therefore, it is not relevant to TI. To answer your second question, MRc1.2 is calculated by comparing the previous interior layout of finishes to the new layout. This is confusing for most people because it is not calculated in the same way as NC MRc1.1. Instead of looking at the new layout and calculating was was reused, you have to look at the previous layout and calculate what remained in the new design. That said, if there were unfinished exterior walls "used as finish" and they will remain in the new design, you could calculate the interior surface as reused. Same goes for the flooring and ceiling surfaces if they were "structure as finish" in the previous layout. Does that clarify how to do the calculations?
