Our LEED-CS project is a commercial office tower locating on the retail podium. The office tower only would be included in the LEED boundary as it is separately operated and the retail podium do not want to pursue LEED. The rooftop area (top 3 floors) of the tower will be F&B managed and operated by the retail management.

The top floors will have separate air handling units, outdoor air units, ventilation fans, lighting systems, and elevators. Electricity, chilled water, and cold water serving the area are supplied from the office towers plant but metered separately.

Can the top floor, including the building façade and the exterior roof surface enclosing it be excluded from the LEED projects boundary.

Here are an example of drawn boundary

I was not able to open the example drawings, but I worked on a project back in 2009 under the LEED v2.2 rating systems that achieved certification for the residential floors above a ground level retail floor that had separate ownership and independent building systems. We provided the legal description show the residential building was separate from the retail building even though they were vertically stacked, as well as drawings showing the plan view and building elevations/sections depicting the LEED project boundary.
