Abstract
Recently, retroreflective materials have attracted attention as one of effective countermeasures against urban heat island phenomena. However, it has been pointed out that increase of the incident angle to the surface weakens the retroreflective performance of these materials along with growing the specularity. In order to improve the summer heat environment of the city block, it is necessary to recurse much of the solar radiation even during the time when the sun is high. The purpose of this research is to evaluate the effect of layout of retro-reflective materials on solar radiant reflection characteristics of city block by a model experiment. We carried out comparison of the distributions of both incident and reflected energy between combinations of installing materials to both the exterior building wall and the ground surfaces in each case by using the model experiments. From the investigation, it was found that installing the RR materials to the building and the ground surfaces improved the solar radiant reflection performance of the city block, and also strengthened the directivity of the reflection
