What is the minimum required outdoor ventilation air in CFM per person for an auditorium with an estimated maximum occupant load of 150 persons per 1000 sqft?

To determine the minimum required outdoor ventilation air in CFM (Cubic Feet per Minute) per person for an auditorium, it's important to refer to standard protocols set forth in building codes or standards like ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers).

For assembly areas like auditoriums, the typical requirement ranges are generally established to ensure sufficient air quality and comfort for occupants. In many contexts, the standard often used is around 15 CFM per person for areas where occupants are seated and may be there for extended periods, such as in an auditorium setting.

Given the scenario, the minimum required outdoor ventilation air per person should be at least 15 CFM. This ensures that there is enough airflow to mitigate the buildup of carbon dioxide and other indoor pollutants generated by occupants. In this case, selecting the value of 5 CFM would be substantially lower than what is necessary according to these commonly accepted standards, which is likely why that was not the accurate choice.
