| Résumé : |
The exponential growth of urban areas has produced what is called the "Urban Heat Island" effect with heat-absorbing roofs being among the chief culprits. Houses with concrete slabs which are directly exposed to sun become very hot during summer and very cold during winter. The phenomenon of urban island is becoming increasingly more intense in urban areas modifying the microclimate of these areas and aggravating the climate. The desirable reduction in this can be achieved by using cool coatings which may be heat reflective or heat insulative in nature and has found applications in various sectors. A brief overview of cool coatings has been described in this paper and it is one of the ways to conserve the energy and reduce the energy consumption. |
