Dear collegues,
We are in early design stage of multifunction building, with retail, offices and residential floors. We are trying to apply LEED requirements for water use, but it is not clear for me how to document or even propose fixtures and appliances in residential units. Those probably will be outside of GC/Investor scope, therefore will be dependant solely on furut user. In other instances leasing agreement might work, but in terms of residential I assume it is not possible to oblige anyone to enything.
Should we then exclude such units from calculations, as they are not within the scope? Or should we assume baseline cases for the water use there? Would appreciate your opinion - residential part is significant as it is a little less than 50% of the building.
Thanks,
Andrzej

This is probably too late for your project, but good to try and answer for general reference.
I would verify how to treat the unknown residential spaces with LEED Coach for sure. My gut thinks that you would still have to account for the unknown fixtures - much like Core & Shell projects do for their unknown tenants - and you would have to assume the same fixture rates as what's allowed by code, since you could not guarantee that anyone would choose to install better than code (the LEED baselines are better than local codes in many locations). The exception would be if you could prove via signed leases that the tenants would not install anything worse that "x" (whatever the limits chosen by the building owner), but for that to work, all tenant spaces would have to be accounted for, which does not sound feasible here, and is often not feasible for core/shell projects, either. Simply stating that requirements would be in the lease, even if confirmed by the building owner, was allowed in older versions of LEED, but not in v4 or 4.1.
