Requirements:
HVI recommends ventilation rates based on 8 air changes per hour. For most bathrooms this works out to 1 CFM per square foot of area, with a minimum of 50 CFM.
A bathroom less than 100 square feet:
Calculate 1 CFM per square foot of floor area. A minimum of 50 CFM is the required ventilation rate.
A bathroom larger than 100 square feet:
To calculate the proper ventilation rate, add the CFM requirement for each fixture; toilet 50 CFM,shower 50 CFM, bathtub 50 CFM, jetted tub 100 CFM. Note: For proper sizing,the static pressure (SP) needs to be calculated.
