Pursuing EAc6, Option 1, for office building registered as C&S for LEED certification, the following issue is kind of not clear to me:

Normally, when a building type is Core and Shell, the idea is the tenents of this  building to be able to complete its Fit-Outs as per their needs.

Following the above, could the terms Core & Shell and Tenant areas be considered as identical for the purpose of Design Energy Cost calculation?

Your support is highly appreciated.
