Our system cannot provide enough outdoor air to meet ASHRAE 62.1-2010 due to design limitations. How much outdoor air must we provide to meet Case 2 instead?

If your system has physical or design constraints that limit the possible outdoor airflow for the system below the ASHRAE prescribed rate, you must determine the maximum possible flow for the system and supply that amount in operations. In that case, the flow must be at least 10 cfm per person to meet the prerequisite. However, if your system can actually provide more than 10 cfm per person, you must do so up to the design or operational capacity of the system.
