impervious surfaces, which lead to less shade and moisture. Therefore, less water is
evaporated and surface and air temperature is increased as illustrated in Fig. 16 .
Many studies have been carried out to develop the technologies to mitigate the
impact of the heat island. Cities have to decrease thermal losses (thermal conduc-
tivity) and to control thermal gains (solar radiation). In order to achieve that,
