This research analyzed the effects of strategies to mitigate urban heat islands by means of numerical simulation, as applied to an actual street block in central Tokyo (Marunouchi district). The analysis method consisted of heat transfer calculations, CFD calculations, and evaluation of the effectiveness at mitigating an urban heat island. The results of this study demonstrated that covering roadways with water-permeable materials, and planting grass and trees on-site could reduce air temperatures and mean radiant temperature, whereas covering roadways with highly reflective paint would increase mean radiant temperature, and lead to environmental degradation.
