1. What is a Blower Door?: - a diagnostic tool designed to measure the airtightness of building and to help
locate air leakage sites.
- the fan blows air into or out of the building to create a slight pressure difference between inside and outside.
- this pressure difference forces air through all holes and penetrations in the exterior envelope
- the tighter the building (eg. fewer holes), the less air you need from the blower door fan to create a change in building
pressure
- problem spots are easier to find using chemical smoke, an infrared camera or simply feeling with your hand.
- it can also help you access the potential for backdrafting of natural draft combustion appliances by exhaust fans and
other mechanical devices
- help to determine the need for mechanical ventilation in the house
2. Basic dynamics of air leakage in buildings: - for air leakage (infiltration or exfiltration) to occur,
there must be both a hole or crack, and a driving force (pressure difference) to push the air through the hole.
3. Five most common driving forces which operate in buildings are:: 1) STACK EFFECT
- warm air rises due to buoyancy & leak out the top of the building and replaced by colder outside air entering the
bottom of the building. (winter time)
(Reverse stack effect is summer time only)
2) WIND PRESSURE EFFECT - exposed areas will have wind go right it
3) POINT SOURCE EXHAUST OR SUPPLY DEVICES - chimneys for combustion appliance and exhaust fans push air out
of the building when they are operating
- air leaving the building from these devices causes a negative pressure in the building which draws outside air into
holes and cracks in the building envelope
- supply fans (eg. positive pressure ventilation fan) deliver air into the building creating a positive pressure which
pushes inside air out of the building through holes and cracks in the building envelope
4) DUCT LEAKAGE TO THE OUTSIDE
- leaks in supply ducts act like exhaust fans creating negative building pressures
- leaks in return ducts act like supply fans creating a positive pressure in buildings
5) DOOR CLOSURES COUPLED WITH FORCED AIR DUCT SYSTEMS
- imbalances between supply and return ducts can dramatically increase air leakage
- eg. closing of bedroom doors can potentially create large duct imbalances by effectively cutting off the bedroom
supply registers from the central return registers located in the main part of the house
4. Common air leakage sites: - as warm air rises due to the stack effect, it tends to escape through cracks
and holes near the top of the building
