Parking Under Cover and SRI Requirement

Hi Summer,  You are not required to have any certain SRI for your roof if you're not pursuing Opt 1 of this credit.

Hello Summer and Emily,  It is probably worth clarifying that according to the NCv4 requirements for this credit, in order for the parking spaces on the top level of a parking deck (or at grade parking) to contribute towards the 75% threshold of Option 2, a roof immediately over such spaces actually would have to comply with a minimum 3-yr aged SRI of 32 (or, if three-year aged value information is not available, an initial SRI of at least 39), or be a vegetated roof, or be covered by energy generation systems.  However, if you are referring to parking that is located under a building (more specifically, under enclosed gross floor area), even the top level of such a parking structure would contribute towards the 75% threshold regardless of the SRI of the roof above the building itself.  An SRI requirement does not exist for parking placed underground, under deck, or under a building.  Parking located directly below other parking levels would all be considered 'under deck'.

We have a few outdoor parking slots that cannot be fully covered. 1.6m out of a 5m length of parking space is left uncovered. Our other parking slots are located under the building. Can we still vy for the option of 100% parking under cover? Thanks

Hi Hannah,  It's wonderful that you are making such an effort to reach the exemplary performance threshold for this credit!  That said, the default assumption should be that a parking space that is not fully covered by qualifying roof/deck/cover cannot contribute towards meeting the requirements.  However, of course, you can attempt any level of achievement for any credit and reviewers will consider special circumstances on a case-by-case basis.  Any pertinent mitigating factors should be detailed for the consideration of the reviewers.

To confirm, if 100% of a project's parking scope was "underdeck", or placed under a building, would a project automatically qualify for Option 2 as there is no roof specifically for parking (and have no SRI or vegetated roof/Renewable energy requirements)? 

Yes.  (However, it should be noted that unless the entire parking garage area in such a scenario also happens to be located under the footprint of the building's gross floor area, it's not likely that 100% of the parking would be compliant as some of it would likely be located, exposed, on the top deck of said parking garage.)
