| Outline of Final Research Achievements |
In order to establish design technique for thermal comfortable environment with the fractal sunshade in urban area, the experiments to confirm the mitigation effects of thermal environment and to the thermal characteristic of the sunshade were carried out at comprehensive outdoor scale model site (COSMO) at Nippon Institute of Technology. As a result of experiments, increasing the division number of fractal, convective heat transfer coefficient is increased. The fractal sunshade has the characteristic to keep the surface temperature from rising by high convective heat transfer. Furthermore, the experiments with fractal sunshade products composed by AES resin. With the value of thermal characteristics, it will be possible to evaluate the effects of thermal environment improvement. Finally, the design technique of thermal comfort space under the fractal sunshade at every conditions, using the outdoor thermal environment simulation software of general-purpose is considered.
