Solutions to support the reduction of the urban heat island temperature and the use of rainwater in a closed loop system

‘Disposing’ of rainwater during heavy rainfall, without having to put it into the sewer system, is a key issue when we talk about adapting cities to climate change. The second issue is its use during dry periods. Through the use of technical solutions such as blue-green retention roofs or systems that facilitate the growth of tree roots under sealed, traffic-laden pavements, we gain the ability to maintain an adequate level of rainwater balance in a closed loop, as well as supporting greenery, which has a significant impact on people’s health and quality of life.
