Passive radiative cooling paints are gaining traction as a sustainable solution for reducing building temperatures without energy consumption. These paints emit infrared radiation, dissipating heat into the atmosphere. Research and development efforts are focused on enhancing the emissivity and durability of these paints, with pilot projects demonstrating significant temperature reductions in urban settings. Currently, the cost of passive radiative cooling paints is higher than traditional paints due to the use of advanced materials and limited production scale. However, as demand grows and manufacturing processes improve, prices are expected to decline, making this technology more accessible for widespread use.
