I am working on a building to be placed on a site adjacent to an existing building. We are adding no new parking and using that as justification for SSc4.4. The city (the building Owner) would like to designate existing parking to satisfy SSc4.3. However, SSc4.3 defaults to 0 on the parking. Has anyone successfully used existing parking to satisfy SSc4.3 in this case? Would the project boundary have to change to include the existing parking to accomodate this?

Hi Nina,
The MRP Clarification document that the USGBC published in Nov 2009 touches on this. From reading the statement below it would make sense for you to exclude the parking from your LEED boundary and take credit for the addition of no new parking. In addition, it seems like you could reasonably add low-emitting parking signs on an existing parking lot that will be used by your project occupants and earn the credit. Although, you will not be able to use these signs for any other LEED projects (no double dipping).
On page 14:
Facilities (including parking) outside the LEED project boundary used for compliance specific credits
- Facilities (including parking) that are not within the LEED project boundary but are used to demonstrate compliance with a credit or prerequisite, as allowed per the rating system and reference guide, need not be considered for other prerequisite, edit, or MPR compliance. However, those facilities cannot be used to show compliance for other LEED projects, unless the sufficient capacity is present.
- EXAMPLE: Off‐site showers used to show compliance with Sustainable Sites credit 4.2, Alternative Transportation, Bicycle Storage and Changing Rooms in LEED NC need not be included in the calculations for Water Efficiency prerequisite 1, and cannot be used to earn this credit for an additional LEED project unless the required shower‐to‐FTE ratio is met for both projects.
