Calculation Steps

  1. Determine the area of the space in square feet.
  2. Identify the required air changes per hour (ACH) based on the type of space.
  3. Calculate the volume of the space by multiplying the area by the ceiling height.
  4. Multiply the volume by the ACH to get the total air volume per hour.
  5. Divide the total air volume by 60 to convert it to CFM (Cubic Feet per Minute).
