Recently, high-albedo materials and products have been developed to lower the surface temperatures of urban building roofs and roads. In this paper, outdoor exposure experiments and a numerical simulation are conducted to identify the effectiveness of reflective paint. The optical and thermal properties of 137 kinds of reflective paint are measured according to JIS (Japan Industrial Standard) method. In addition, sensible heat emission and heat load are calculated considering a change in the paint performance deteriorated by outdoor exposure.
