This paper aims at developing the solar-radiation reflector with retroreflective abilities, in order to aim at reduction of urban heat island effects, and building cooling loads of a summer season. However, although retroreflectors have some researches which should be referred to in the aspect of visibility, the knowledge on solar-radiation reflection is not accumulated. This is because the general purposes of the retroreflectors are reflecting plates, such as a road sign. Therefore, in this study, the numerical simulation which used the ray tracing method performed the case study, and the reflective property on a direct-beam solar radiation was analyzed. Furthermore, possibility that high reflection performance would be realizable compared with a diffuse reflection was shown.
