Louversiding

bi-colored siding on a louver system

White siding on a house helps reflect heat in the summer. Dark colored siding absorbs sunlight, and helps heat in the winter. Why not set up a "louver" type system, which would rotate the louvers of siding to a different color, depending on whether you want to absorb, or reflect the heat of the sun? Better yet, have a chemical, or electrochemical reaction that would change the color of the siding without using mechanical actuation. Maybe roofing too?

       I think there are also systems in production, similar if not the same. When I read this I had visions of sliding down the side of the glass pyramid at the Louvre.
