METHOD 1
1. Calculate cu ft of occupied space.
2. Multiply by recommended air changes per hr (AC/h).
3. Divide by 60 minutes per hr to convert to CFM.
Example:
2000 sq ft with 8 ft ceiling, 0.35 air changes per hr (AC/h)
(2000 sq ft x 8 ft ceiling x 0.35 AC/h) / 60 min/h = 93.3 CFM

METHOD 2
1. Multiply number of people times 15 CFM/person.
2. Multiply number of bath rooms 20 CFM/each.
3. Add 25 CFM for kitchen.
Example:
2 people, 2 baths, 1 kitchen
(2 x 15) + (2 x 20) + 25 = 95 CFM
