HVAC system in a core and shell warehouse

Dear all, I am developing a simulation of a warehouse (core and shell) that is still under construction. At this stage, it has not yet been defined any tenant. However, it is expected in the future the establishment of an office space and a conference room. For the moment there is no definition of those areas in plan or the areas needed, and hence there is no HVAC system set for these, only one ventilation system in the warehouse area. Should I consider the simulation of an HVAC system for office and conference room areas that doesn't yet exist, using a system of Table G3.1.1B Annex G of ASHRAE 90.1 2007 both in baseline and proposed cases, or should I not consider any HVAC at this stage in any of the simulations? Thank you in advance!

Without a design you model the HVAC identical to the Baseline. It may be difficult to get enough savings without some part of the facility being designed first or without specific tenant requirements in the lease agreement.
