Let's innovate together to rethink the products of our cities<\/div>\n

Under the combined effect of increasing urbanization and global climate change, the warming of our cities (day and night) is intensifying. Heat waves and heat waves are occurring more frequently and with increasing intensity.<\/p>\n

The consequences of urban heat are becoming increasingly visible. Increasing urban temperatures are expected to expose more citizens to the negative health effects of extreme heat. These health problems can include exhaustion, heat stroke, and worse...<\/p>\n<\/div>\n

It is illusory to consider the use of air conditioning as the only answer to rising temperatures of our cities, both from an energy and environmental point of view. According to a report by the International Energy Agency, the development of air conditioning in emerging countries would cause a doubling of CO2<\/sub> emissions<\/strong> by 2050.<\/p>\n

Faced with the challenge of the urban heat island impacts, our scientific team is collaborating with many industrialists to create the adaptive coatings of tomorrow<\/strong>.<\/p>\n

The phenomenon of urban heat islands<\/strong> forces us to rethink the products<\/strong> that surround us in our modern cities. Outdoor spaces, especially public spaces, have an important role to play, as do the facades surfaces and roofs of buildings.<\/p>\n

In the city, solar energy is stored in the products of buildings and the asphalt of roads or parking lots, and this energy is released into the urban atmosphere at night (heat urban island effects). The difference in temperature can reach 10\u00b0C on a daily basis between the city center and the countryside.<\/p>\n

To rethink a material, our teams analyze your product<\/strong> and its components to diagnose whether an absorbent coating should be developed to create a dynamic optical barrier<\/strong> or, on the contrary, to limit as much as possible any absorption<\/strong> responsible for thermal heating.<\/p>\n

One of our strengths is our multidisciplinary approach<\/strong>, with complementary skills in chemistry, thermodynamic, photo-physic, etc. This know-how enables us to support our industrial partners in their green approach and design of product<\/strong> for effectively limiting the impacts of urban heat islands in summer in our cities.<\/p>\n<\/div>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div>

To limit the effect of urban heat islands<\/strong> in summer, one strategy is to create an optical barrier. The idea is to absorb the sun's energy on the surface like a natural shadow. The advent of intelligent materials that change color according to an external disturbance such as solar radiation and\/or temperature makes it possible to consider the creation of this type of interactive and intelligent barrier. The objective is to capture only the solar radiation when the intensity and\/or temperature becomes too high.<\/p>\n

To create this type of dynamic optical barrier with the sun<\/strong>, we exploit the thermodynamic processes of smart products that have the ability to modulate their optical response depending on temperature, light...<\/p>\n
