Keep the Heat Out, Use Window Treatments – Air Conditioning Appreciation Days
The sun’s rays can light up a room, but they can also heat it up. In the summer, it is a good idea to keep windows that are in direct sunlight covered during the day to reduce heat gain, subsequently reducing your cooling load.
Light colored window coverings, at least the part facing the window, can be the most beneficial. White backings on curtains or white blinds will help reflect the sun’s heat back outside.
According to the U.S. Department of Energy:
- “medium-colored draperies with white-plastic backings can reduce heat gains by 33%”
- “when completely closed and lowered on a sunny window, highly reflective blinds can reduce heat gain by around 45%”
- “window awnings can reduce solar heat gain in the summer by up to 65% on south-facing windows and 77% on west-facing windows”
For those who hate blocking out all the sunlight during the day, consider at least using blinds and flipping them up so that the sunlight comes in and hits the white ceiling. A white ceiling will help disperse the light and limit the heat gain, but certainly not eliminate it.
