Urban areas are scattered with artificial heat sources. Dense buildings use a large number of materials with high heat storage and large heat-absorbing surface areas. This increases the temperature in urban areas, causing the heat island effect. Biology has long been living with the environment, and has developed different strategies in response to the environment. Therefore, I hope to use the function of biological heat dissipation to create an open space that can convert hot air into cool air and recycle rainwater for cooling.
