I'm working with a hospital project that will be pursuing LEED for Healthcare. The scope of work may include renovations to an existing parking structure that will provide parking to the hospital. The parking structure and hospital are on opposite sides of a busy road and will be connected by skybridge. If the parking structure renovations fall under the hospital scope of work, it will be included within the LEED project boundary.

I'm wondering if any other projects have had success submitting MRc1.1 for a parking structure (or other building) where the reused building is not the primary structure in the LEED submittal? Would the parking reuse be calculated as a percentage of all construction or just as a percentage of the reused building construction?
