The definition for roof area indicates that only the roof area directly above the Gross Square Footage should be used for the Option 1 - 75% calculation. However, on our project site, there is a maintenance/stoarge building. It is not connected to the project building, has no occupants, no plumbing or HVAC units. It is enclosed (walls, doors etc). Do we need to consider this other building's roof area (above its Gross Square footage) in the Option 1 compliance path? It appears that it should not be included in the Option 1 copmliance path calculation, but can anyone confirm that it doesn't apply?

I'm not 100% sure whether your required to include that roof area or if it should be excluded. But, given that the intent of the credit extends beyond cooling loads and electricity consumption in the building, it seems like a good idea to include.
If the project is compliant either way, I would include the area and then add a narrative explaining that you've included both roof areas. This is important also to explain any inconsistencies this might cause with values reported in the PI forms.
