Radiative cooling (RC) is a passive cooling technology that involves the process of a surface losing heat by emitting infrared radiation. This phenomenon can be harnessed in building materials, such as cement and concrete, to reduce heat accumulation in urban structures and pavements. By incorporating materials with high emissivity into the concrete mix, these surfaces can effectively radiate heat back into the atmosphere, particularly during nighttime, leading to cooler building surfaces and reduced urban heat islands.
