All Texans are looking for ways to reduce the demand on their air conditioner this summer. And we all know that a large source for solar heat gain is our windows. Lets get smarter about windows and watch those summer energy bills drop.
For many homeowners it might finally be time to
replace your current windows
. Replacing outdated inefficient windows can make a big dent in your energy bill. But what makes a window energy efficient? Please refer to this comprehensive guide --->
Selecting Energy Efficient Windows in Texas.
So what about some other strategies?
The Department of Energy says that smart management of window coverings can reduce heat gain by up to 77 percent. And, as a bonus, these same practices can reduce heat loss in the winter. Take a close look at the windows in your home and we bet you can take further steps to keep things cooler in the summer, One study found that 75% of residential window coverings remain in the same position every day. If this describes your habits, be strategic about which coverings you open in the morning. In the summer, you may want to keep certain window coverings closed to reduce heat gain. During the hottest months many people will keep windows covered during daylight hours.
Outdoor Options
Awnings
offer an excellent defense against the sun in Texas' perpetually hot weather. Exterior awnings can reduce solar heat gain by up to 65 percent for south-facing windows and 77 percent for west-facing windows.
according to the DOE
. For best results choose awnings in light colors that reflect more sunlight. In the winter, you can roll up retractable awnings to let the sun warm up your house.
Exterior Shutters & Shades
Exterior shutters and shades are usually made of a variety of materials, including fabric, wood, steel, aluminum, or vinyl. They are very effective at reducing solar heat gain. Most exterior shutter systems include a mechanical crank, rod, or motor to allow operation from indoors. This can help encourage daily use of the shutters, and may be required by local fire codes.
Interior Options
Shutters
Interior shutters can really enhance the design in a room and will provide excellent heat control. Wood is a great option, but also consider
Sunburst Polywood Shutters
. They are more energy efficient than any other window treatment: up to 70% more than wood shutters and 1600% more than aluminum mini-blinds. Polywood Shutters are also much more durable than wood.
Curtains/Drapes
The ability of curtains and drapes to reduce heat gain depends on fabric type (closed or open weave) and color. Studies show that medium-colored draperies with white plastic backings can reduce heat gain by 33 percent,
according to the DOE
. Hang the curtains as close to the window as possible.
