Radiative cooling is a process by which a material cools down by emitting thermal radiation. This phenomenon occurs when an object loses heat by emitting infrared radiation to its surroundings, typically to outer space.
Where:
- is the power radiated per unit area (in watts per square meter).
- is the Stefan-Boltzmann constant (5.67×10−8 W m−2 K−4).
- is the surface area of the object emitting radiation.
- is the absolute temperature of the object (in kelvin).
