Whole-House Fans: A Green Energy Solution

How is it possible to get the same amount of comfort in your home, but cut your air conditioning-related costs by up to 90%? With a whole-house fan system, it’s possible. Whole-house fans use one-tenth the amount of electricity as standard HVAC units, but also replenish the supply of fresh indoor air much faster — up to four times per hour. Practical, economical, whole-house fans are simply the smart choice in eco-friendly home cooling. Would you flip a switch and open a window or two if it meant reducing your cooling expenses by 90%? Sounds almost too easy, right? Using a whole-house fan is super-easy. All you have to do is open a few downstairs windows and turn on your whole-house fan. That’s all you have to do to drastically improve your home’s indoor air quality while also doing your part to help the environment. How Do Whole-House Fans Work? In simplified terms, a whole-house fan works like a siphon; it uses the difference in pressure to push hot air out of the home while pulling fresh, cool air into the home. Of course, to make the system work, you will need to have one or more windows open in the home, preferably at the first-floor level. Most homeowners will leave their whole-house fans on overnight and throughout the morning. This has the effect of thermally resetting the home. Around mid-day, if the heat outside gets too hot and it’s starting to impact the comfort of those inside the home, you can always close the windows and allow the air conditioner to generate cooler air. How Whole-House Fans are Great for the Environment Your air conditioner is like the most power-hungry residential appliance you have within your home (in terms of monthly electricity usage). In fact, air conditioning applications use more power than air handlers, humidifiers, ceiling fans, freezers, cooking appliances, pool pumps, microwaves, laundry washers, hot tub pumps, and several other electrical appliances — COMBINED. So, anyone looking to create a more eco-friendly home should list their air conditioning units as as “public enemy #1”. Let Nature Cool Your Home The reason that whole-house fans are so effective in cooling indoor air while using very little energy is that Mother Nature and the laws of physics are doing much of the work. Simply by creating an air pressure imbalance that is imperceptible to the people inhabiting the home, you are able to pull in refreshingly cool air from the outdoors at a fraction of the cost it would take using a standard AC unit. Good for You, Good for Your Wallet, and Good for the Environment Since most of your electrical usage goes toward powering your air conditioner, that equals a good chunk of change each month. By using a whole-house fan, you are not only improving the quality of air within your home, but also reducing Don’t Confuse Whole-House Fans with Attic Fans While whole-house fans are installed in your attic’s floor and an attic fan is, well, installed in an attic, the similarities end right there. Attic fans exhaust hot air from the attic without replenishing any air within the home. Whole-house fans, on the other hand, push out the hot, stale air from your home through the attic. The negative pressure created from this action pulls in cool, fresh air from the outdoors. Improve the Quality of Your Indoor Air, Too< Unless you just skipped to the end of this article, you’ve read about how whole-house fans are great for the environment and will drastically reduce the amount of electricity required to cool your home. But, one area that we’ve glossed over in this post is that whole-house fans can drastically improve indoor air quality by removing stale, polluted air from the home and replacing it with fresh air from the outdoors. How polluted is indoor air? The EPA has found that indoor air can be anywhere from 5-100 times more polluted in our homes than the air outside. Having a whole house fan installed is one of the best ways to improve your indoor air quality, cut your cooling costs, and increase the comfort of your family.
