FAQs about MRc1.1 :

How do exterior elements, such as a covered dock, get counted? Would that be considered a slab or exterior hardscape and not part of the building?

What building elements get included in this calculation and what can be excluded?

Should I base my calculations on plan or elevation?

How do you calculate the existing building structure reuse?

We are constructing a new building next to the existing building, the two buildings will not be attached. Essentialy the client is building a new building to expand out of the existing building but keeping the existing building for storage and extra space. The existing building is only 3200 sf and the new building is only 5000 sf, so far the new building is not 2x the existing building. Would this credit count even if the two buildings are not physically attached, and as far as I know the existing building is not being renovated?

Brian, this is not straightforward, as you might have guessed.  Is the old building going to be in the LEED boundary? It would surely have to be to be considered for this credit. However, once you have it in the LEED boundary, questions are raised about how you count it for other credits. Does it have FTE occupants? If yes, then it should probably be certified separately. If no, then it could probably (in my opinion) count here, but you'd have to include it in other relevant credits as well. (Will it have HVAC?)The LEED MPR supplemental guidance would be a good reference here.

I am not sure how often the existing building is going to be occupied since right now it is used for flight medical simulation, as wil the new building. Once the new building is complete, the equipment in the existing building is going to be moved to the new building, possibly leaving the existing building open for storage or undetermined use. Yes, the new building will have HVAC. I believe the existing building will fall into the LEED Boundary since the utilities for the new building will tap into those serving the existing building and be routed around the existing building.
