Identifying LEED boundary to exclude portion of project

The registered project includes commercial core and shell space with an adjoining housing tower which will be scored under the Evergreen Sustainable Development Standard. In terms of relative square footage, over 60% of the total project area is associated with the commercial Core and Shell, therefore we have registered the project under core and shell. The team has currently drawn the LEED boundary to exclude the housing portion of the project because the phasing of the project has the housing portion being constructed after the commercial core and shell space and the housing is potentially part of a separate construction contract and separate set of documents. Please advise if this approach is acceptable.
