Do we need to document out of scope HVAC equipment?

I am working on a project where all of the AHUs, except for one, are provided by the building owner. Thus, the scope of work is limited to the provision of one AHU (for the IT Room), the redistribution of existing units, and the ductwork. My team would like to pursue OPTION 1 (Equipment Efficiency). In order to do this, do we need to document out of scope HVAC equipment? Or would it suffice to provide project-specific load calculations for the IT Room only, in order to comply with Section 1.4 of the Advanced Building Core Performance Guide? Thanks for your help.
