radiative cooling
Radiative cooling is a natural process where an object loses heat by emitting infrared radiation. This occurs when the surface temperature of an object is higher than its surroundings, allowing it to release energy in the form of electromagnetic waves. This process is most effective during clear nights when the sky is open, enabling heat to escape into space.
This phenomenon is commonly observed in various materials, including roofs, pavements, and even plants. Engineers and scientists are exploring ways to enhance radiative cooling for applications like energy-efficient buildings and cooling systems, which can help reduce reliance on air conditioning and lower energy costs.
