you can save money and the planet
You can save money and the planet by changing the color of your roof. Dark roofs are better in cold areas because they absorb solar radiation and trap more heat throughout the day, while light roofs are better where it’s warm because they reflect radiation keeping things cool. As for Regions that have seasons, researchers have developed a coating for your roof that changes color. One method involves covering the roofs with a black layer topped with transparent cells filled with temperature sensitive solution. When the solution is cool, it’s see-through letting the black layers show through and absorb radiation, but when it’s hot the molecules collapse and turn the roof white to reflect the heat away. Roof coatings like this could make houses up to 31.5 percent more energy efficient, which is how you can save money and the planet.
