How do we address non-certifiable Parking Garage ?

HI, I previously posted a similar message in the MPR forum but there was no reply and am reposting it here as it pertains to MRc4/c5/c6. Here goes: We are seeking LEED certification for a new office building. A new separate parking garage building (under the same construction contract) falls within the LEED Boundary. I understand that the parking garage will not be certifiable as it does not meet the MPRs for occupancy. The MRP Supplemental Guidance on page 26 states that "If there is a non-LEED-certifiable building within the LEED project boundary, the project team can include the non-certifying building within the project boundary in ALL relevant submittals that are allowed and appropriate for each individual credit and prerequisite, essentially treating the non-certifying building as an extension of the certifying building." We plan to include the non-LEED-certifiable building for the SSc7.2 heat-island non-roof & SSc4.1 credit, but are not sure if we can exclude this building from MRc4/c5/c6. For the Default Budget or Actual Budget for the MR's and IEQ's credits, must we include the construction cost of the non-certifiable parking garage if we are considering it for the SSc7.1 credit? Do we have to consistently apply the inclusion of the non-LEED-certifiable building across all credits? Thanks.
