Solutions to keep cool and keep the Earth cool too

Now than summer has arrived in the Northern hemisphere, some of you might be willing to put to an end to the excessive heat in your homes and offices.

Naturally, air conditioning comes to mind. But as this solution is very energy intensive and releases HFC – very powerful greenhouse gases – alternatives are sought.

The Daily Green provides us with data on fans (pictured left) and clearly show their advantages when compared to A/C.

As the Daily Green states in its article :

According to Harvey Sachs of the non-profit American Council for an Energy-Efficient Economy, the movement of air over the skin is what’s key to keeping the body cool. So instead of turning on that A.C., see which direction the breeze is blowing outside (no matter how minimal it may be), and then open a few windows strategically to try to get it flowing through the house from end-to-end or side-to-side.

If the breeze alone isn’t enough, apply some fan power. Even small tabletop fans, which can be had for $30 or so at Target and similar stores, can really whip the air around. Placing one facing in by the window where air is coming in, and one at an opposite window positioned to blow warm air out, can create a nice “wind tunnel” effect in pulling air through the house.

This strategy can be especially effective at night when it is cooler. But then it’s important to shut the windows when you leave for the day in the morning to keep the cooler air in and the warmth of the new day out. Keep blinds shut and curtains drawn, too, as sunlight pouring into the house only creates more heat. And remember that lights left on are not only wasting electricity — they’re creating heat, as well.

Ceiling fans also do a nice job of circulating air in the rooms you occupy most, and though they do require some up-front costs for installation they use only about 1/30th the electricity of a room air conditioner.

Beyond moving the air around to keep cool, the website lists several tips for using water to keep cool sans AC. One tried and true method is to wet your wrists and other pulse points with cold water, and then keep those spots cool by holding an ice cube wrapped in a face cloth against them. The relief is immediate, and this method will cool down the entire body — by as much as three degrees Fahrenheit — for upwards of an hour.

Another WikiHow suggestion: Wear a short-sleeved shirt and keep the sleeves wet with cold water (from a squirt bottle, faucet or hose). Keeping the pant legs of long pants wet is also a good way to keep your legs cool. Add in a breeze or a fan, and you can actually get cold.

Of course, if you just can’t live without air conditioning, there are greener options out there. For starters, a single window unit that keeps one room cool is far less energy intensive and polluting than central air conditioning that keeps all the rooms in the house (including those you’re not using) cool. Look for new models sporting the federal Energy Star label, which marks units as energy efficient.

Another option for those in hot, dry climates is an evaporative cooler, which cools outdoor air through evaporation and blows it inside the house. These units make for a nice alternative to traditional central air conditioning, as they cost about half as much to install and use only one quarter of the energy overall.

It is the first time I write on daily tips for a more environmentally friendly lifestyle and I hope you liked it.

Don’t hesitate to comment this article as it will enable me to know if you want more of those or if I should stick just to energy and climate news. In any case, enjoy and stay tuned !

  2. Fans and evaporative coolers are a good solution in hot and dry climates. However, when you are living in a humid climate, and you do not want to use any air conditioning, there are also dehumidifiers that extract excess moisture from a room.
