    Abstract

    The development of energy-efficient roofing systems has been of intense interest in numerous countries in recent years, as a measure for reducing the energy consumption of air conditioning during hot weather. In this study, fifteen kinds of membrane waterproofing materials with high solar reflectance were exposed respectively to varying atmospheric environments at six locations within Japan in order to investigate the range of reflectance reduction. In addition, the relationship between the retention rate of reflectance after exposure and the mass of the ingredients and their composition adhered to the surface of waterproofing materials exposed.
