Hello,
We are working on a project in NY, which is a major renovation. The project will demolish all the envelope but will keep most of the structure (roof structure, columns, and beams); however, there will be changes in slabs and the addition of columns to reinforce the structure. We are still deciding if register the project as NC or Warehouse. We will conduct an LCA; therefore, the project will follow option 4 in the building life-cycle impact reduction credit.
My questions are:
Can I claim savings due to reusing the building structure?
And if so, is it correct to use the procedure for calculating the savings according to the “small-scale reuse” process in the LEED guideline?
Thank you

Yes, you can very much take credit for the reused structure in your LCA. And also yes, use the "small-scale reuse" process in the reference guide. Even though reusing the structure doesn't feel very small-scale, that's the right methodology. It might also be worth checking your calculations for Option 3, which rewards material reuse based on areas. But if you're doing an LCA anyway, compare both options and see what's advantageous. And don't forget to use as much fly ash or slag in your new slabs as the engineer will let you! That'll help with your performance and impact.
