Sci Show: Berkeley Lab engineers have developed a roof coating that can keep a building warmer or cooler, depending on the weather. When it’s warm out, the material will reflect sunlight & heat, but this radiative cooling automatically switches off in winter, reducing energy use for both heating and cooling.
