LEED CS with partially occupied building

hello everybody, this is my first post on leeduser and I want to start giving compliments to everybody are sharing so lot of knoweledge; returning to building, a design team described me this context: - 10 floor building with 4 of them occupied by tenant and 6 of them free. the owner wants to: - renovate the envelope - install new hvac - renovate the 6 floor that are not occupied (no tenant fit out) - add 2 more floors - do all of this work without moving out the 4 tenants note that is not possible to use leed EBOM because the 4 tenant that occupy the 4 floors are not interested. Do you see any conflicts in using leed CS ? thank you very much and happy easter !
