It is a big box 'speculative warehouse' that is pursuing Core & Shell cert since there are no restrooms, no office buildouts, etc. within the CS scope of work. The lights however are fully installed within the CS scope of work. 

The lights are demonstrating a significant energy savings when compared to the LEED baseline however GBCI has referred us to LI #10463 and is not allowing us to claim more than 20% energy savings unless we provide a TSLA signed by the tenant. 

I could not disagree more with this LEED interpretation, when applying it to projects that install lights within the CS scope of work. 

A while back I spoke with GBCI about our approach, and they mentioned that we should provide lighting plans/schedules to confirm energy savings calculated by the eneryg model. Now they want a signed TSLA from the tenant.

Has anyone been able to claim 20%+ savings from lights without a signed TSLA?
