A new article on EnergyPortal.eu explores the natural process of radiative cooling, which allows these systems to emit heat as infrared radiation, effectively reducing energy consumption and greenhouse gas emissions. The systems are particularly suitable for hot and arid climates, and recent advancements in materials science and engineering have enabled radiative cooling even during daylight hours. 

A key technology are the so called "photonic radiative coolers", new materials that radiate heat away into space, even under direct sunlight, while their high reflectivity minimizes heat absorption from the sun. One of the pioneers in this field is SkyCool Systems, a company that has introduced a thin film coating that can be applied to surfaces like rooftops, providing passive cooling and potentially leading to significant energy savings in cooling applications.
