No cooling in Proposed Building

Our proposed building has no cooling system installed; it is ventilated naturally. Now Appendix G says to model the proposed building like the baseline bldg system. That means with a VAV. In other buildings that are cooled by chilled ceilings in the office areas and not cooled in toilets and storage I always modeled baseline and proposed building like the actual design (not cooled). Now, can I ignore the cooling system if the whole building has no cooling like I did in partially cooled building or do I have to implement a VAV cooling even if there is no space for this system? Would appreciate any helpful comment or discussion! Johannes
