Block that Sun!
When sunlight enters your house, it turns into heat. You’ll keep your house cooler if you reduce solar heat gain by keeping sunlight out.
- Close the drapes: Line them with light-colored fabric that reflects the sun, and close them during the hottest part of the day. Let them pillow onto the floor to block air movement.
- Add awnings: Install them on south- and west-facing windows to reduce solar heat gain by up to 77%, says the U.S. Department of Energy. Make your own by tacking up sheets outside your windows and draping the ends over a railing or lawn chair.
