1.3 TECHNICAL SUPPORT (FOR ASSISTANCE)

These are the two most common methods used to evaluate the ventilation needs of a house:

CSA F326 and Canadian Building Code:

• High speed: 10 cfm per room

20 cfm for the master bedroom and the basement

• Low speed: 40-60% of high speed

ASHRAE Standard 62-2001:

• 0.35 air change per hour

Refer to ventilation code of your area to determine which method to use.
