Hot and humid area

There should be no deviation from the Appendix G baseline systems in your baseline model. Keep in mind that the baseline HVAC does not have to make design sense in each case. As for the tenant spaces, if a system is not being installed then the proposed and baseline systems should be identical. I know you can claim savings for lighting power density reductions if they are included in the tenant guidelines so you could try applying the same logic to HVAC savings in the Tenant spaces. Check the CIRs from V2.2 to see if there is any precedent for doing so.
