Passive radiative cooling paint
Web36 Therefore, a passive cooling strategy that cools without electricity could significantly impact global energy 37 consumption, as well as human (especially infant) and pet safety. 38 Radiative cooling is a promising candidate to meet this cooling need for overheated spaces under direct 39 sun illumination 5. The Earth’s atmosphere has a ... WebOne alternative to energy-intensive cooling methods is passive daytime radiative cooling (PDRC)—a phenomenon where a surface spontaneously cools by reflecting sunlight [wavelengths (λ) ~0.3 to 2.5 μm] and radiating heat to the cold outer space through the atmosphere’s long-wave infrared (LWIR) transmission window (λ ~ 8 to 13 μm).
