Historic Building Cold Dark Shell

Under Option 1 you need to show the minimum savings. Since you are making envelop improvements you can claim those savings. Any tenant related savings would need to be from requirements in the lease agreement.

Under Option 2 all you need to do is meet the AEDG requirements for the scope of work. In this case just the envelop. The rest of guidelines do not have to be in the lease agreement. You will earn the prerequisite and one EAc1 point.

I am working on a very similar project. It's a small historic building with no MEP in the Core and Shell scope and minor envelope upgrades. How should the team document IEQp1 Minimum Ventilation Requirements, if the mechanical ventilation system is part of the TI scope? Can we simply include ventilation requirements in the Tenant Guidelines?

I would think that they need to be in the lease agreement.

Hi Tommy,

Did you receive any clarification from the GBCI on whether ventilation requirements can simply be included in the tenant lease to meet IEQp1?

Thanks!

I have a follow up question regarding EAp2 compliance for a cold, dark shell. The building I mentioned above is 40,000 SF office building historic gut rehab, so it would not be able to use AEDG (only for office buildings less than 20,000 SF). The only other prescriptive option would be the Core Performance Guide, Sections 1 and 2. The only work in the CS scope is minor envelope upgrades due to historical constraints, so all of section 1 would not be applicable and only sections 2.4-2.6, and even those may be difficult to achieve due to historic preservation requirements.

Is the energy modeling the only option for complying with EAp2 for this particular project?

Sounds like it, yes.
