I don't understand Case 2.
If meeting the outdoor airflow rates in Case 1 is not feasible because of the physical constraints of the existing ventilation system (...). Supply the maximum possible to reach the minimum setpoint in Case 1
How can the minimum setpoint in Case 1 be reached if "meeting the outdoor airflow rates in Case 1 is not feasible"? Probably I'm misunderstanding the meaning of "minimum setpoint".

Hi Francesco, for Case 2 you need to supply at least 10 CFM per person, and then beyond that you're asked to "supply the maximum possible to reach the minimum setpoint in Case 1". So they're basically saying, if you can supply something in between the 10 CFM minimum, and the minimum requirement for Case 1, then you need to do that. You don't have to reach Case 1 but you have to get as close as you can, after hitting the 10 CFM requirement. Does that help or confuse things more?

Hello, would this also apply to extraction requirements when systems are unable to meet the required exhaust rates?
