N2 - Heat transfer characteristics of cool coating for building roofs in the tropical climate have been investigated by formulating a cool roof heat transfer (CRHT) model for transient heat flux through a cool-coated multi-layered roof (MLR). Furthermore, the impact of the cool coating on heat flux through roof was quantified by extending the CRHT model to estimate the equivalent thickness of uncoated roof required and the equivalent thermal insulation material thickness to be added over uncoated roof to achieve the same daily heat gain as for a cool-coated roof. It was observed that the impact of cool coating is much more significant for low R-value (5- 15 cm2- K/W) roof materials, such as metal roofs, as compared to high R-value (<800 cm2-K/W) roof materials such as concrete, asphalt shingle, wood shingle, etc.
