We have a project with 3 buildings located on the same plot, that are physically attached by two underground levels made up of technical rooms, parking spaces, bicycle racks, showers and garbage rooms. The three buildings have identical functions and shared MEP systems. However these buildings will have different access points and will be completely separated from the ground level and upwards. This project will be certified under Core and Shell. Can we certify the three buildings together (as one building) and receive one certification for the project? Or do we have to certify them separately?
