Tenant agreement to exclude PFP boxes

In our project location, it is clear that no tenants will go for a heating system. The base building is also designed for cooling only. Identical heating coils will be modeled in base and proposed case. In the tenant agreement, we are clearly advising the tenant to install standard VAV boxes. With this, can we exclude the modeling of PFP boxes in proposed case? PFP boxes will be modeled only in base case.

If there will be no heating system installed then adding heating coils (and setting the temperatures so they never come on) seems like a waste of time to me. Tell the reviewer that rather than add heating coils and a heating set point that would ensure that the heating would never run, that you have not modeled a heating system in either case. Simply advising the tenant is not enough. You must require them to do so in the lease agreement. If you don't then the system gets modeled identically.
