Joe Doucet's climate-adaptive paint changes color based on temperature, turning black below 77°F and white above. This thermochromic paint could save energy costs significantly—estimates range from 20% to 30%. Cities have begun using reflective paints to combat urban heat, as demonstrated by the Million Cool Roofs Challenge and L.A.'s reflective street project, effectively lowering temperatures in targeted neighborhoods. Doucet's innovation could transform building exteriors according to seasonal changes, displaying colors reminiscent of nature's adaptability.
"It's phenomenal to think about the built environment changing with the seasons as nature does," says Doucet, who estimates that painting a building with this climate-adaptive paint could save an average of 20 to 30% on energy costs.
The power of paint has been harnessed in urban areas to combat issues like the heat island effect, as shown by various international initiatives.
