FACT - The mushroom style attic
fan lowers the overall cost of cooling.
FACT - A whole house fan will
pull fresh air in, and vent it out
through the attic at less than half the cost of air conditioning.

Whole House Fans -
Ventilate for cooling.
There are a wide variety of types and systems. They can be
mounted just about anywhere (ceilings, closets, crawl space, attic,
etc.. They are typically located in a central area to help evenly remove warm
air from the living space. When a whole house fan is turned on it
helps draw warm air out of the living space while drawing in cooler
outside air from open windows.
Sizing a whole house fan
-
Whole house fans are sized in cubic feet per minute (cfm) of
ventilating power. To determine the size you'll need, first
calculate the volume of your house in cubic feet. To do that,
multiply the square footage of the floor area you want to cool by
the height from floor to ceiling. Take that volume and multiply by
30 to 60 air changes per hour (depending on the power you need).
Then, divide by 60 minutes to get the cubic feet per minute of
capacity your house requires:
(Square feet ______ × room height ______) × 30 or 60/ 60 = cfm
required _________.
Installing
and using a whole house fan
-
Installing a whole house fan is tricky and should be done by a
professional. An experienced professional should perform your attic
measurements and install your dedicated circuit wiring and, if
needed, your new attic vents.
Attic ventilation will usually need to be increased to exhaust the
fan's air outdoors. You'll need 2 to 4 times the normal area of
attic vents, or about one square foot of net free area for every 750
cubic feet per minute of fan capacity. The net free area of a vent
takes into account the resistance offered by its louvers and insect
screens. More vent area is better for optimal whole house fan
performance. |
If your fan doesn't come with a tight-sealing winter cover, you
should either buy one or build one. If you switch between air
conditioning and cooling with a whole house fan as the summer
weather changes, build a tightly sealed, hinged door for the fan
opening that is easy to open and close when switching cooling
methods.
Be cautious when operating these large exhaust fans. Open windows
throughout the house to prevent a powerful and concentrated suction
in one location. If enough ventilation isn't provided, the fans can
cause a backdraft in your furnace, water heater or gas-fired dryer,
pulling combustion products such as carbon monoxide into your living
space.

Gable Attic Fans - are
mounted to the gable wall inside the attic behind a decorative
louver. The gable attic fan is connected to a proper power supply and a timer. The
timer allows the fan to run during the hottest portion of the day.
The gable attic fan helps reduce the attic temperature to help
prevent heat transfer down through the insulation and into the
living space. Gable attic fans are typically much cheaper than whole
house fans and also easier to install.
