A residential building in Saint-Louis (Haut-Rhin) has a depolluting facade. It would neutralize the CO2 of 20 cars per year, or the equivalent of 50 trees.
As COP26 draws to a close, many initiatives are emerging in terms of the environment. This is particularly the case in Saint-Louis, in the Haut-Rhin. A building has a facade that is at first glance normal, except that its red bricks are not decorative. They would make it possible to clean the air. Cement contained in bricks absorb gases such as CO2. Thanks to the sunlight, an oxidation phenomenon occurs which will accelerate the decomposition of the particles before being released into the atmosphere. They are then non-polluting.
The construction of this facade had an additional cost: 100,000 euros just for the bricks. Inside, the architect opted for less polluted construction materials, such as natural paints for example. Materials that cost on average 5% to 10% more expensive. However, to afford 80 square meters, a couple spent around 250,000 euros, not necessarily more expensive than accommodation in a new classic building.
