Scope in a C&S shopping mall

We are working on a new shopping mall. as usually in my country, a anchor store (tenant deparment store) was first developed and constructed, and now is operating. The other common, concourse and stores spaces are being designed and the project will be a C&S with the owner scope only in common and concourse areas. The tenant area that already exits is included in the scope of the LEED C&S certification, but is not in the scope of the owner. Should I demostrate compliance of this prerequisite for this are that is not in the owner scope? If so, Should I model this space even though is not in the owner scope with equipment that already exits? There is any way I may exclude this tenat in the scope of the C&S certification shopping mall, I mean do not consider that space in any credit? Thanks you! Dante Garcia
