A cool house is a nature-friendly house. It reduces the consumption of air conditioners, which comprises of more than 50% of the average household energy consumption. How does light colors affect the temperature of a house?
Light colors reflect UV rays
Notice that when you wear a white shirt, you magically feel cool and comfortable. And when you wear a black shirt, you feel very hot. That is because black absorbs all the heat coming from the light of the sun, while white reflects everything. The lighter the color of the shirt, the more heat is reflected and the cooler you feel.
This is especially true in houses. The lighter the color of the walls and roof, the more UV light is reflected and the cooler the house.
Light colors are cool
Using light colors for the facade and roof makes the house significantly cool as it reflects the heat. The cooler the house, the less air conditioners that the homeowner will use and less energy they will consume. This makes the house nature-friendly as it reduces the energy that is drawn from power plants.
