G3.1.1 exception d states that if a kitchen has an exhaust hood airflow rate of greater than 2400 l/s, a secondary HVAC system should be used for that space. What would be the modelling approach if the exhaust is less than 2400 l/s, would the same primary baseline HVAC system be used? Would the same exhaust rate be assigned to the kitchen as the proposed case?

G3.1.1d does not state that you should be using a secondary system. These are exceptions to the primary system and therefore replace it. It states that you should use a system 5/7 for the kitchen instead of the primary baseline system from Table G3.1.1A if the hood airfloww is greater than the value you cite. If it is less then you would model the primary baseline system. Kitchen echaust is a process load so it should be modeled identically with the same exhaust rate and schedule.
