How to calculate ventilation airflow per person
This calculator finds ventilation airflow per person by dividing total outdoor airflow by number of occupants — the same core relationship used across ventilation-per-person calculations.
How the calculation works
Airflow per person = Total outdoor airflow ÷ Number of occupants.
Example
600 CFM for 30 occupants: 600÷30 = 20 CFM/person.
Frequently asked questions

Pro Tips for Ventilation Airflow Per Person
- Compare against your applicable ventilation standard's minimum CFM-per-person requirement for your specific space type and occupancy.
- Recalculate as occupancy changes, since this figure directly depends on how many people are actually present.
Common Ventilation Airflow Per Person Mistakes to Avoid
- Using a static occupancy count for a space with significantly variable occupancy (like an event space), when actual ventilation adequacy depends on the real-time occupant count.
