CASE HISTORY

A sustainable choice for an industrial square in Turin

In November 2022 in Turin, the combination of two technologies, namely the transparent binder Resina LT and the white oxide Iteroxid 100%-GR-HP, was used for outdoor flooring at a production site of a famous luxury goods brand . The choice of these products is linked to the notable benefits they have on the surrounding environment: in fact, both technologies allow the lowering of the temperature of the flooring.

The area affected by the works amounts to 5.200 mXNUMX and is located in via Giulio Cesare in Turin. The work was carried out by the company Co.ge.fa SpA in collaboration with Iterchimica.

The use of products such as oxides and transparent binders allows the temperature of the flooring to be lowered by approximately 18°C ​​less than a traditional black flooring. This data was confirmed by a research project entitled "Thermal analysis of road pavements” conducted by the University of Padua in collaboration with Iterchimica, to demonstrate the characteristics and technical performance of road pavements made with light materials.

According to studies conducted in the laboratory (artificial light) and outdoors (sunlight), the use of transparent binders for road paving guarantees better albedo (ρ) values. The albedo is a value between 0 and 1 which coincides with the ability of a material to reflect solar radiation and consequently not retain it. The higher the values, the greater the reflective aptitude of the material examined. In the specific case, the albedo value of a flooring created with this technology is equal to 0,497, compared to a traditional black flooring which has an albedo value of 0,107.

The second useful parameter in this study is the Solar Reflectance Index or the Solar Reflectance Index (SRI). It generally has a value between 0 and 100. The higher the index, the more the surface exposed to solar radiation will remain "cool" (i.e. it will have a low rise in temperature and heat absorption). Studies conducted by the University of Padua have shown that, by using transparent binders and light-coloured oxides, the reflectance index reaches the maximum value, i.e. 100.

These data demonstrate how the paving of the new industrial square in Turin will make it possible to mitigate the heat island phenomenon, improving liveability within the surrounding area. Furthermore, the colored solutions allow the road surface to adapt more harmoniously to the context and improve its visibility, contributing to architectural integration with the surrounding landscape.

From a landscape and urban design point of view, this solution also allows for better integration of the paving with the surrounding environment and a more pleasant visual impact.
