In Yokohama City, in addition to the effects of global warming, the heat island effect is also increasing. The average annual temperature is rising over the long term, and this is resulting in hundreds of hospitalizations for heat illness every year.
A fractal sunshade is created by arranging a large number of leaf-like pieces in a three-dimensional structure. A feature of this design is that the temperature of the shade itself remains relatively low because of heat dissipate more easily. The fact that the temperature of the sunshade itself can be kept low means that heat radiation, compared to shade provided by material in a single plane, can also be reduced.
Details in the Local Adaptation Interview.
N.B. Prof. Satoshi Sakai, Graduate School of Human and Environmental Studies, Kyoto University, invented and obtained patents for the fractal sunshade. Two domestic companies (LOSFEE co., Ltd. and SEKISUI HEIM SUPPLY CO,.LTD) are licensed to manufacture and sell fractal sunshades.
