Calculation method
Calculation method
Room volume (m³)
Room volume × supplied air changes per hour; no prescribed ventilation-rate lookup.
Required airflow (m³/hour)
Room volume × supplied air changes per hour; no prescribed ventilation-rate lookup.
Required airflow (litres/s)
Room volume × supplied air changes per hour; no prescribed ventilation-rate lookup.
Symbols and units

- User-selected air changes (per hour)
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; Room volume × supplied air changes per hour; no prescribed ventilation-rate lookup. 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.
