I am working on a LEED-NC project that is primarily an outpatient facility but has some future shell spaces for Retail and some for future expansion of the outpatient facilities. I can use Appendix 1 from LEED-CS for the retail shell spaces default FTE but there is nothing listed for future healthcare outpatient default FTE counts.

The area that is being finished as part of the LEED-NC scope has an actual FTE count, coming directly from the project owner. Would I just use that same ratio for the shell spaces? Since they are owned and managed by the project owner and will never be leased out to any third party, as per the Owner's letter of commitment.

Does anyone know of an LI for this issue?
