questions about additional HVAC system in kitchen

Our project is a high rise building, which consists of offices, bank, dining area and so on. Now it is under the LEED V3 CS review. I have a question about the spaces which are not normally conditioned. In our proposed building, kitchens are designed as unconditioned spaces, which only contain exhaust fans and supply fans. So I set these spaces as unconditioned zone in both proposed and baseline model, and put the fan power in the electric meter directly to calculate the energy cost of these fans. The technical advice of reviewer told that an additional HVAC system type should be reflected in the baseline model for the kitchens. I know that according to the exception (b) of Section G3.1.1, additional system types must be included in the Baseline model if some spaces have occupancy or process loads or schedules that differ significantly from the rest of the building.(e.g., data/telecom rooms, kitchens, movie theaters), but in this project, the kitchens are unconditioned spaces, no cooling and heating system is used in the kitchen. The question is that if I use system3 or system4 in the baseline model, can I keep the kitchens in the proposed model still as unconditioned spaces? Or should I add the same system in the proposed model? I feel so confused about this question, looking forward to the help and advice
