IRFLOW
•
The airflow rate of fresh air and stale air required throughout the house must be
calculated by adding together the airflow required for each room, as indicated in
the shaded columns below, unless calculated by a qualified professional. Airflows
are denoted in cubic feet per minute (cfm) or liters per second (l/s).
•
The smaller a room is in comparison to the other rooms, the closer the airflow rate
must be to the “Min” value.
Bigger rooms will require airflow rates closer to the
“Max”
value.
