Ventilation Rate Calculator helps contractors and tradespeople accurately size, spec, and estimate materials and systems.

Formula

Ventilation = Outdoor Air per Person × Occupants + Area × Outdoor Air per sf

Guida passo passo

  1. 1Apply ASHRAE 62.1: 5-15 CFM/person + 0.06 CFM/sf
  2. 2Apply the formula using your project measurements
  3. 3Add required safety factors or waste allowances per code

Esempi risolti

Ingresso
10 people, 1000 sf, office zone (5 CFM/person + 0.06 CFM/sf)
Risultato
Ventilation = 10×5 + 1000×0.06 = 110 CFM

Errori comuni da evitare

  • Not applying code-required safety factors or derating
  • Forgetting to account for waste and cut losses in material estimates
