Cool Paints and Cool Tiles: As the threat of global warming becomes widely recognized, scientists have proposed quick techniques based on simple ideas, such as cool roofs and cool pavements, which save energy, improve comfort. Increasing the solar reflectance of urban surfaces results in reflecting more of the incoming global solar radiation, hence, counters global warming. Painting the walls and roof with cool paints is one of the effective passive cooling techniques. Passive cooling technique is based on simple fundamentals of physics by implementing mechanic of slow heat transfer into a building.
