| Outline of Final Research Achievements |
It is shown that cool islands can be created in the city using fractal sun shade. This method does not rely on plants like greening, does not use resources such as electricity and water, and utilizes the characteristics of the city itself that the city is covered with concrete and asphalt with large thermal inertia and improves the environment.
As a result, during the sunny summer day, the temperature lowered by 3 degree at the fractal sun shade maximum compared to the control group. Considering that it is not so big sunshade of 20 m × 20 m under conditions of high air turbulence and extremely easy mixing, it can be said that it is an extremely large effect.
