For centuries, older houses had no such thing as air conditioning for relief during the warmer months. Instead of flipping a switch, the following eco-friendly, old-school methods were used to get air flowing through the house during the dog days of summer.
Using the passive-cooling principles that hot air rises, and cool air moves toward warmer air, you can design or retrofit your house to make use of fresh air to stay cool and invite in those long hot days of July and August.
Open Up the Room
Since hot air rises, and cool air moves toward warmer air, a house that has vented openings on both sides of the building has a lot more airflow – and any air movement is a good thing. Using operable windows on the cooler side of the house, you can open them wide to draw the air through from the hotter side of your home.
Shutters Aren’t Just for Outdoors
Shutters can be useful inside too. Shutters aren’t just a decorative alternative to curtains and blinds, they’re also a green way to ventilate – you can open up the windows behind them to let in air, and close the shutters to keep out the sun, and voila! The room is cooled down the old-fashioned way.
It’s Obvious, but: Fans
Fans have been used since ancient times to keep things cool, since any air movement is good and a fan can suck away the warm air and push cooler breezes around a space. Ceiling fans are available in every conceivable design, whether you want something unobtrusive or bold. Fans are even offered in retro palm-frond styles, and most fans also offer a light fixture combination if you don’t want to lose overhead lighting when you install the fan. Look for fans with a reverse switch or feature for winter, which helps push warmer air (it rises, remember?) back down into the room.
Take it Outside
Screened-in porches have long been an architectural staple in hot regions, and they deserve a comeback. Consider enclosing your covered porch, or enclosing a deck with screens, and you will have created an airy, insect-free outdoor living space. You can use a screened room for months, provided you furnish it with pieces made from materials that can withstand some rain, like wicker or metal. Bonus: a generous couch with some indoor-outdoor cushions becomes an ideal spot to sleep on hot summer nights!
