Ventilation per Number of People Calculator
This calculator estimates the required airflow (Q) based on the number of occupants and the recommended airflow rate per person. It’s especially useful for designing ventilation systems in offices, classrooms, conference halls, and other occupied spaces to ensure air quality and comfort.
Occupant-Based Ventilation Requirement
Airflow per Person Calculation Formula
$$Q = P \cdot R$$
Where:
- $$Q$$ — Required airflow (m³/h)
- $$P$$ — Number of people
- $$R$$ — Recommended airflow per person (m³/h)
Ventilation standards often specify airflow requirements based on the number of people occupying a space. This simple calculation multiplies the number of occupants by the standard air supply rate per person (typically 20–60 m³/h depending on the setting). The result helps ensure sufficient oxygen levels and air freshness in crowded environments.
