On buildings, the roof is the main part of solar radiation to absorb heat. The radiation falling on the roof is either reflected into the atmosphere or absorbed into the building by conduction. Any absorbed solar radiation will heat the roof surface and some heat will enter the building. The higher the absorption of solar radiation, the higher the energy consumption, keeping the building cool; Mainly by air conditioning, which is widely used in large buildings. By lowering the temperature of the building surface and reducing the heat entering the building, air conditioning can save energy. By protecting the external surface of the building from the heat radiated by the sun, the external surface temperature can be reduced. Several technologies to prevent solar radiation have been put forward, among which the use of cold pigments has aroused great interest in the past few years. Cold pigments refer to pigments with high near-infrared (NIR) solar reflectivity or low near-infrared solar absorptivity, which are widely used for coating or coloring sintered colored sand on roofs and external walls of buildings.
