Discussion of Results
Leakage rate
The measured air flow at atest pressure of 50 Pa was 681.75 CFM which equates to an equivalent leakage area
of 287.0 sq in, based on adding up the leakage from all the holes and cracks inthe exterior.
This leakage also equates to a one inch gap, 23.91 feet long. Your home leaks as if there is one hole this size in
the wall.
Air leakage in your ducts to the outdoors was not measured in this test but can greatly increase the above loss
rate and can also cause air quality problems. Repairing this type of duct leakage should be the first priority.
Safety concerns
Your home may already be suffering from air quality problems due to pollutant sources. A proper whole house
diagnostic routine by a certified tester will go a long way to identifying solutions. Whenever changes are made
to house and duct leakage, a thorough evaluation of the "house as a system" will optimize comfort, energy and
air quality while ensuring a higher degree of safety and protecting the integrity of the structure of your home.
Ventilation
The air inyour home will be replaced with outdoor air every 56.66 minutes on average. That is about 1.06 air
changes each hour.
This air change rate will provide annual per person ventilation of {EstimatedAnnualVentilationCFMPerPerson}
CFM of fresh air each hour which is sufficient. According to the ASHRAE standard 62.2, your home does not
require any additional ventilation even when windows and doors are closed. Bringing in air from aclean
outdoor location and removing stale indoor air from kitchens, bathrooms and other locations may still be
important in order to improve air quality. Ifair sealing work is undertaken, the air leakage rate must be re-
measured to determine ventilation requirements based on the new leakage rate.

Fan Pressure (FP) is the measured fan pressure when using aself-referenced fan or when Room Pressure (RP) is
negative. If using afan which is not self-referenced, and Room Pressure is positive, Fan Pressure is calculated by
subtracting the measured Room Pressure from the Absolute Value of the Fan Pressure.
IfPrA>0and fan is not self-referencing: FP = |PrB|-PrA
IfPrA<0or fan is self-referencing: FP = PrB
Flow calculations are not valid if Fan Pressure is less than either MF or (K2 x |RP|).
