LEED boundary and Major Additions

A new project, under LEED-NC, is a major addition to an existing building, in this case a manufacturing facility which will result in basically three sections New Office, Existing Office, and Existing Manufacturing Area. Can the LEED boundary and energy credit only include the addition(office) and existing building(office) if both the new addition (office), existing building(office), and existing building (manufacturing plant) all share a common central plant? The energy from the plant will be apportioned appropriately to 2 of the 3 building sections. Seem reasonable? Thanks.

I understand why you might want to exclude the manufacturing area but technically the whole project should be included in the LEED submission. MPR #2 indicates that the entire project should be included.
