Why is there an urgent need to refresh our cities?
The concreteization of cities and the absence of vegetation increase heat reverberation, and hence temperature rises. Thecool island is a tailor-made response to the need for urban cooling. It creates a zone that maintains a lower temperature than the surrounding area. It also plays a role in the overall fight against urban heat.
In addition to providing thermal comfort for users, the creation of “cool islands” meets the challenges of public health and environmental protection. In some places, temperature differences of 5 to 10°C can be observed between the city and the surrounding countryside, or even between a street and an adjacent urban park. These figures explain the importance of protecting the population against the effects of global warming, especially vulnerable people such as young children, pregnant women, the sick and the elderly…
