An attic-mounted whole-house fan pulls hot air into the attic space (where it exits through vents) while drawing cooler nighttime air into the living-space through open windows. To improve whole house airflow, and reduce the visual impact, fan intakes are often centrally located in hallways. BeginnerWhole-house fans, sometimes improperly referred to as “attic fans,” are a class of fan that exhaust air from a house, drawing in fresh air through open doors and windows. Whole-house fans have been in use in the United States for much of the last century, although their mass appeal has been eroded by the availability of air-conditioning and inexpensive electricity. Natural or “free cooling” is based upon how much cooler the outside air is than inside air.
A rare, but promising application of whole-house fans is to incorporate ground-source cooling.  If you have a basement that stays cool all summer, you effectively have the basis for a ground-source cooling system. Is lower cost more important than features like automatic louvers, low noise level, and power use?
California has relatively high electrical rates that rise rapidly as electrical consumption increases (tiered rates). Sacramento houses require cooling during a significant portion of the year (see graph, above). Climates that undergo large temperature drops at night (10°F or more below indoor temperature) and houses with lots of thermal capacity are ideal matches for whole-house fans. The most basic whole-house fans are equipped with self-closing dampers (aka backdraft dampers), which close by gravity and open when air pushes against them.
Since whole-house fans discharge into the attic, it must be sufficiently vented so that pressure does not build up. Foregoing modeling—and ignoring the best way to save on cooling energy (sweating it out or heading for the lake)— it’s possible to compare how much energy a whole-house fan versus air-conditioning will save.
A larger airflow can compensate for smaller inside-versus-outside temperature differentials, such as those that occur in the early evening or during humid weather. The simplest method to determine the economic viability of a project is to use “simple payback”—dividing the capital cost by the annual savings. Environmentally minded folks might be interested in calculating their carbon offset in cost per ton of carbon dioxide (CO2) avoided. Whole-house fans allow homeowners to naturally achieve comfortable indoor conditions while minimizing energy use and improving indoor air quality. Neil Smith has spent the last quarter-century in the HVAC world, having obtained a degree in building engineering.
A Home Power reader inquires about sizing a generator for pumping, and expert Dan Fink responds. Some of the newer style of whole house fans are extremely quiet and do not require any framing. I just turn on the bathroom exhaust fans to do suck warm air up and out--shouldn't this have the same effect as a whole-house fan?
The Hayward Power-Flo LX pool pump is a new and improved high-performance pump series designed for the rigors of above-ground and on-ground type swimming pools. A whole-house fan exhausts hot air out through the attic space, or directly to the outside. While backdraft dampers offer basic protection against debris (and rodents) from entering the house, they have no insulating qualities. Some whole-house fans use a remote fan connected to the plenum box with flexible ducts, which is a great acoustical attenuator.
There are many factors that affect human comfort, from temperature and humidity to individual sensitivity.

Computer software can predict energy performance quite well, including how whole-house fans will cool a house. Probably the oldest form of air cooling, the technique of evaporative cooling dates back to ancient Egypt. Get a jump on summer with this comprehensive look at incorporating whole-house fans for more efficient cooling. When the days heat up, these passive cooling strategies can help you reduce your reliance on air conditioning. Attic fans work without hvac, if one opens a lower window can cool down a home in 15 minutes.
Good brief article - I'd like to mention a 'swamp cooler' that does NOT put the humid air into the house - has additional heat exchanger humid air to house air. This Franklin 1 HP motor has a corrosion-resistant stainless steel exterior and splined shaft. By clicking Confirm bid you commit to buy this item from the seller if you are the winning bidder. Import charges previously quoted are subject to change if you increase you maximum bid amount. USB port: smartphones, tablets, ipad, external battery pack, GPS units, digital Camera, PSP video games, bluetooth headset and any other 5V USB devices. Whole-house fans are used to cool a house when the outside air temperature is lower than inside (see figure), and are a convenient and innocuous way to provide inexpensive cooling.
For houses with existing air-conditioning, the most basic strategy is to use whole-house fans to eliminate air-conditioning use at night.
Your climate and personal comfort will help determine if you can use a larger whole-house fan to extend the time when air-conditioning is not required. This involves running a whole-house fan all night, bringing in cool air so that the building is as cool as possible the next morning. A low-cost way to take advantage of this cooling is to open one or more basement windows, and run a whole-house fan during the day. The homeowner has just finished paying another $600 summertime electrical bill and he wants to slash that cost. To reduce noise from the fan, you’ll need to consider acoustic reflection or simply the distance the fan will be from listeners. Typically, cutting joists is unnecessary—the area directly below the whole-house fan is framed to form a channel for the air and support for the grille or backdraft damper. These backdraft dampers offer basic protection against debris (and rodents) from entering the house, but have no insulating qualities. Otherwise, fan performance can be jeopardized and pressure buildup could force air back through openings in the ceiling, along with dust and other particulate matter. To figure dollars per ton of CO2, take the capital cost of a project and divide it by the lifetime avoided carbon dioxide emissions. This is a simple project that springboards on existing technology, and by economic and environmental measures, offers a quick payback on investment. Combining durable,rrosion-proof construction with advanced features and options, Power-Flo LX pump sets the standard for value and performance.
Pulling air through a duct consumes extra electricity, a consideration when you’re weighing energy use. Based upon user feedback collected by Neil Smith, mechanical engineer and owner of AirScape Fans, a fan that delivers a minimum airflow per bedroom of 500 to 700 cubic feet per minute (CFM) is generally recognized as sufficient. They cost about half as much to install as central air conditioners and use about one-quarter as much energy—for the fan and a small pump that keeps the pads saturated with water. My parents have had a Daikin unit for a few years now, and I just installed a new Mitsubishi Hyper-Heat unit in my house.

If you reside in an EU member state besides UK, import VAT on this purchase is not recoverable. A pre-cooled structure will stay cool longer the following day, saving additional air-conditioning use and providing comfortable conditions later into the day. The other inhabitants of the house are noise-sensitive and will make little or no lifestyle changes to save energy. Because of decorating choices, and the fact that it’s a central location for airflow, the vast majority of whole-house fans are installed in hallway ceilings.
Whole-house fan manufacturers publish the requirement for attic ventilation in terms of square feet of net free area.

It took him a couple of hours to install it and after he completed the job he said it was the easiest whole house fan he ever installed. However, with careful selection of motors, duct size, and fan blades, this energy cost can be minimized. The richest Egyptians would have slaves fan large clay pots of water to keep the air moist while they slept.
If installed without ducts, evaporative coolers are usually placed in a central location as window units.
The only lifestyle change required is to turn off the air-conditioning, switch on the fan, and open windows on cool nights.
As whole-house fans become available that have good power unloading (reduced energy use at low speeds), this upsizing becomes more practical. For homes with sufficient thermal mass, the entire house can be pre-cooled sufficiently to eliminate air-conditioning. For example, climates with hot, humid summers can make use of natural cooling during the spring and fall. Airflow paths through the house can be determined by which doors and windows will be opened to ventilate the house.
For houses without attics, homeowners may choose alternate fan locations, such exhausting to a garage or crawlspace. If a homeowner opts for a non-insulated model (they are significantly cheaper), then manually insulating the fan in winter is highly recommended. This parameter (also known as net free ventilation area—NFVA) was devised to approximate the equivalent of an unrestricted opening.
The fan itself is installed in a centrally located hallway ceiling that opens into the attic floor.
Evaporative cooling was also widely practiced in the Americas from colonial times on as people hung wet sheets on their sleeping porches on hot nights. Larger units can direct the cooled air through the home’s ductwork for effective whole-house cooling. The disadvantages are that they require annual maintenance (changing pads), and are only suitable for arid climates.
A whole-house fan that has enough airflow to maintain cool sleeping conditions “most of the time” would be selected, which translates to a minimum airflow per bedroom of 500 to 700 cubic feet per minute (CFM), depending upon local climate.
There are a limited number of roof-mounted whole-house fan on the market, although this market will undoubtedly grow as more sealed attics are built. Several whole-house fans use a remote fan connected to the plenum box with flexible ducting, which is a great acoustical attenuator. As shown in the table (above), velocity through each vent should be about 500 feet per minute to maintain a safe attic pressure.
For houses without attics, homeowners may choose alternate fan locations, exhausting to a garage or crawl space.
To allow the warm air to escape, you’ll need to have at least one window open on the opposite side of the house. But they can cool a room by 5°F to 15°F, and may be used to cut back on air conditioning use at certain times of the year.
The result is the CFM you’ll need for a complete exchange of air every one to three minutes.
Most roof vent manufacturers will stamp the net free area required on the vent body as well. However, with careful selection of motors and fan blades, this energy cost can be minimized. If manufacturer’s data is not available, several online venting calculators are available (see Access). With enough airflow (think: motorcycle riding), one can be cooled in almost any temperature. These self-closing dampers close by gravity and open when the fan’s moving air pushes against them. However, at some point, the energy to pull all that air with a whole-house fan will be more than using air-conditioning.
