Hi,
We have a LEED v4 ID+C CI project that is a substantial renovation. It's 8 floors and receiving a new HVAC system for the entire building, but there are many peculiar situations:
- Floors 1 through 5 are gutted and rebuilt
- Floor 6 is receiving a new HVAC system and nothing else
- Floor 7 is receiving a new HVAC system but will be converted into leasable space, and the new tenant will be doing a fit-out, complete with lighting
- Floor 8 is receiving a new HVAC and lighting system, but won't be gutted
My question is about floor 7, which is sort of a CI project inside a bigger CI project. For the purpose of the energy model, it'll be modeled with LPD identical between the baseline and proposed case. But my concern is with the Mandatory Provisions requirement of daylight dimming controls. Since this space isn't receiving a new lighting system as part of the project, we won't be specifying any automatic controls. But we're claiming credit for the proposed HVAC system in the space. Will this be an issue? Is it okay if we claim credit for HVAC savings in that space, and then the future tenant(s) claims lighting savings (and ensure compliance with lighting Mandatory Provisions) of the same space? Or would we need to include some sort of language in the tenant agreement to make sure they comply? There is no guarantee they'll pursue LEED.
These issues are explicitly addressed in the Core and Shell rating system, but I am not aware of how it's treated in this "box in a box in a box" scenario.
Thanks,
Waleed
Ps. LEED v4 energy code is more stringent than the local code. These concerns are solely regarding LEED

This is just like modeling a shell space within a LEED BDC-NC project. Either way you just need to model the lighting energy use identically. So I think you could make the case for not modeling the lighting controls. You do not have to include the mandatory provisions in the tenant lease agreement.
