We are working on a CI project which occupies portions of four floors in a University Medical Research Building. The LEED project is being undertaken by a medical research group leasing space within the research building. The whole building is owned by the University.

We considered the LEED project as the area leased by the research group; about 40,000 SF. HOWEVER, there is another 17,000 SF that is considered "limited scope" area, which is NOT being leased by this entity, but through which the HVAC system, which is being re-done, passes. In these spaces, only portions of the HVAC equipment, registers and ceiling system will be replaced.
We would prefer to exclude these "limited scope " spaces, as we have no control over the occupants, their purchases, the existing plumbing facilities that they use, etc
If we go that way, how does the MEP work with the energy model? At this point, the whole area of the full and partial scope is included.
In addition, as the new system is ventilating both the full scope and partial scope areas, would these be covered in the IEQp1/c1/c2?
I assume that we would not consider the partial scope areas for IEQp6.1 & 6.2.
Thanks
