You’re probably aware that colors and materials used in the home have an effect on your mood. But did you know that paint color and building materials also affect indoor temperatures? Just like wearing black clothes on a hot summer day is going to make you feel extra toasty, compared to if you wore white, paint colors and building materials will have a similar effect.
The color of your walls will affect how much heat (or cold) air will seep into the home. According to the National Renewable Energy Laboratory, “Dull, dark-colored home exteriors absorb 70% to 90% of the radiant energy from the sun that strikes the home’s surfaces.” This absorbed energy is then transferred into the home through conduction, thereby increasing indoor temperatures.
An easy solution is to paint exterior walls with a light color. White walls absorb 35 percent less heat than black walls, lightening the load on your air conditioner. If white walls don’t appeal to you, then consider other light colors.
In addition to paint color, windows are another way the home absorbs unnecessary heat. Windows transfer about 40% of unwanted heat to the home. One way to reduce heat transfer through windows is to have reflective window coatings. If you’re planning on doing some remodeling, then consider the possibility of installing reflective window coatings to naturally cool the home.
A home’s building materials also impact indoor temperatures. Brick, concrete and stone walls transfer less heat, compared to lightweight wall materials, and will do a better job of keeping your home cool during the day and warm during colder seasons. This is because dense materials have high “thermal mass”, which is the ability to absorb and release heat slowly.
Other Ways to Cut Cooling Costs
You could also consider installing shades or awnings to limit how much sunlight enters the home. Planting trees at the south end of your property is another way to keep your home naturally cool.
