Try another scenario
- Occupants (count)
- 21
- User-selected outdoor air per occupant (litres/s)
- 8
- Floor area (m²)
- 100

Calculation method
Calculation method
Outdoor airflow (litres/s)
Outdoor airflow = occupant count × rate/person + area × rate/area; user supplies applicable rates.
Outdoor airflow (m³/hour)
Outdoor airflow = occupant count × rate/person + area × rate/area; user supplies applicable rates.
Symbols and units
- a
- Occupants (count)
- b
- User-selected outdoor air per occupant (litres/s)
- c
- Floor area (m²)
- d
- User-selected outdoor air per area (litres/s m²)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- User-supplied measurements and assumptions; Outdoor airflow = occupant count × rate/person + area × rate/area; user supplies applicable rates. Supported limits: Finite numeric values bounded to 1e9 magnitude; lists and tables contain 1–100 records unless a stricter bound is stated. Inputs use the units shown. Lists explicitly paired by a method must have matching lengths; independent polynomial coefficient vectors may differ. Respect stated physical, interpolation, policy and computational domain limits.
