Cooling in a warming world | Science
A completely different cooling strategy is to use materials that regulate heat in the form of infrared radiation. Passive radiative cooling materials take advantage of an atmosphere window for infrared radiation to eject heat into space. When deployed on rooftops, these systems can potentially cool buildings by a few degrees, even in the daytime. Along the same lines, textiles may be modified so that heat can more efficiently radiate through them, allowing people to be more comfortable at higher thermostat set points.
