Sizing (Example) for maximum airflow normally required.
HRVs are typically sized to ventilate the whole house at a minimum of 0.35 air changes per
hour. To calculate, simply take the square footage of the house (including basement) and multi-
ply by the height of the ceiling to get cubic volume. Then, divide by 60 and multiply by 0.35.
Example: SQFT of House 1100
Basement 1100
Total SQFT 2200
Height of ceiling x 8
Cubic volume 17600
/ 60
Maximum airflow required (CFM) 293
x 0.35

* Always consult your local code for sizing requirements in your area.
Room classification Number of rooms CFM (L/s) CFM Required
Master bedroom x 20 cfm (10 l/s) =
