Hi all,

I am working on a LEED NC hotel project which has a tenant space located on the ground floor. There are not HVAC designs for the tenant spaces since the future tenant occupants will take care of it.

My question comes to the GBCI reviewing process; would it be acceptable to prove to the reviewer that the minimum OA requirements will be enforced by a binding clause in the tenant lease agreement?

Or does the MEP team have to design the minimum OA for those spaces?

Thanks in advance for your thoughts.

Anyone have insight on Santiago's questions? I think we have the same questions coming up on our project and haven't found clear answers yet.

We have had the same issue as well. GBCI allows owners to sign off on prereq (e.g. EQp1 and Indoor Water Use Reduction prereq) but requires owners AND tenants to sign off if credits are being pursued by future work.

On our project, there was future retail with no MEP systems at the time the building was completed. So we wrote a narrative that the owner signed that stated the future work would adhere to the prereq requirements. The whole building water calc included "retail neutral" plumbing fixtures (e.g. 1.6 gpm water closets, 1.0 gpm urinals, etc..)

Hope this helps!
