This paper aims at clarifying the general properties of ultraviolet (UV) ray reflection of building materials. Firstly, we analyze UV ray reflection photo of building and landscapes in an university campus. It is observed that the intensity of UV ray reflection varies among materials. Secondly, we measured reflection intensity and ratio of UV ray for 42 specimens of building materials, and then classified those materials into 6 groups using multidimensional scaling method. The findings show that the UV ray reflection properties depend largely on the absorption ratio of U V ray and on the shape and roughness of material surfaces.
