We are new to LEED Certification. We are currently bidding for a new LEED v4 ID+C: Commercial Interior Project. The project is currently operating in two floor (26th and 30th), both are separated by 3 floors. The project is going for major renovation and extension of one of the floor. The client want to go for one LEED certification for both floors. I want to know is it possible? They will be completing the project in two phases. Major renovation as first, and extension as second phase. Is it possible to define project boundary in this case? Both floors are connected by common staircase and elevator belonging to the base building

Is there anyways I could clarify this issue from USGBC?
