Black or dark colored in the winter and white, silver, or light colored in the summer, Color Shifting Energy Conservation Houses optimally absorb sunlight in winter and reflect it in the summer dependent upon the seasonal angle of the sun and intelligent use of color shifting paint.

Most houses never move or change their orientation towards the sun while they exist. By planning on the change of the angle of the sun from winter to summer, color shifting paint can be used wisely and profitably by carefully aligning it with the angle of the sun.

The sun generally has a lower angle in the sky during the winter, than in the summer. The sun, if it were a person, while looking at a house painted with color shifting paint, would see it look black (or dark colored) in the winter absorbing its radiation, and white (or light colored) in the summer, reflecting both its visible and infrared radiation, if the paint is aligned properly. Therefore, when the house reflects the sunlight in the summer, it is cooler and less heated by the sun, saving money on air conditioning. And in the winter, when you want to save money on heating bills, the house absorbs the sun’s radiation.

Color-shifting paints contain unique flakes and particles that give paints, inks, coatings, plastics, textiles, and packaging the ability to change color when you view them from different angles. Each multi-layer flake is created by using thin-film technology. Such flakes appear to exhibit a wide range of colors depending on the angle at which you view them and the angle of incidence of light that strikes them. This is similar to the color shifting inks used in 20 and 100 dollar bills by the U.S. Treasury. The color shift can even be seen in low-light level circumstances.

Color-shifting paint is manufactured by the deposition of ultra-thin layered structures similar to those sometimes found in nature, such as soap bubbles, butterfly wings, or sea shells. Precisely controlling the thickness of the multi-layers in the flake structure produces different colors (like diffraction gratings).

Color shifting paint would be used on the roof and sides of houses and buildings.

Color shifting coated metal or plastic siding would be attached to houses considering the angles of the sun in summer and winter.

Color shifting roofing tiles can also be used.

Thin film mirror reflective particles can also be used.

Thus, by intelligent use of color shifting paints and materials, while planning its use according to the seasonal change of the angle of the sun, much energy can be conserved and money saved in the heating and cooling of houses and buildings.
