How smart facades can cool the city
Urban areas can be 1 to 12 °C warmer than their surrounding rural areas. One of the main causes is the use of materials like asphalt, steel, and glass in buildings. These materials absorb more sunlight and retain more heat than green areas. Vehicles, air conditioning, and industry also cause waste heat. And as cities continue to expand, green spaces and their associated biodiversity are diminishing, further reducing evaporation and shading.
By cleverly using existing manufacturing processes, this innovation can compete with traditional facade finishes.
