I am working on a BD+C: Healthcare project that is a new building addition adjacent to an existing hospital. As this building is being designed for possible vertical expansion in the future, we are not placing the chillers that serve the building on top of its roof. We plan on locating the chillers that are dedicated to this addition on the roof of a separate (non-certified) building several buildings away.
In this situation, do we need to include the area of the roof where the chillers are placed within our LEED site boundary drawing? We plan on including these chillers in mechanical systems and energy-related calculations/credits as they directly serve our addition and our addition alone, but we are unsure if that roof area needs to be shown as an "island" that is part of our LEED boundary.

Gordon, I don't think so. You are going to be fully incorporating the chillers into the EA calculations, so what matters about the area is being included in the LEED documentation regardless of site. And I don't think you have "site" or building area that is being disturbed or impacted in another meaningful way.
I would, of course, make a narrative note about this in any relevant spot in the documentation such as the site plan. "Show your work" so you are fully transparent.
