The building is pursuing C&S certification and has a perspective tenant that may fit out the entire space. We are proposing to charge the perspective tenant the entire electricity bill minus the proration of the core and shell floor area.
For example:
building = 100,000 sf Core & Shell = 10,000 sf Tenant space = 90,000sf
electricity paid for by the tenant to be (90,000/100,000) x entire bill.
We plan to install a centrally monitored electronic metering network, detailed guidelines to tenant, clear guidelines for tenant sub-metering per LEED CI, and corrective action strategy.
Our difficulty is determining if we need sub-meters for a building that may become a single tenant.
thank you.

If the tenant is taking the whole building not sure why they would not just pay the whole bill. I don't think prorating based on area is an acceptable practice.

So that leads me to my next concern, does a C&S project that plans for a whole building tenant qualify for the Tenant Sub-Metering credit?
I understand that NC would be the most applicable rating system however at the beginning of the project, tenants were not known. The owner would love to fill out the entire building with this high profile tenant. As the LEED consultant we do not want to lose this 3 point credit.

I think it could. The point of the credit is to have the tenant pay their own utility bills as an incentive to use less energy. If they pay the bill for the whole building then that would work.
You certainly could combine the CS and CI scopes of work into an NC project.

As Marcus said the point is that core and shell space has to pay its own bill while the tenant/tenants has to pay their own bill. This is the intent of the credit.
