What if buildings could adapt to the seasons like trees do?
Nature shifts with purpose—leaves deepen in fall, blossoms fade in winter, colors ebb and flow.
Inspired by this rhythm, designer Joe Doucet has developed a groundbreaking exterior paint that changes color with temperature, helping buildings passively manage energy use.
Imagine a home or office building that is black in the wintertime, but shifts to a white tone in the summer?

This smart, thermochromic paint turns lighter in the heat and darker in the cold. A white exterior in summer can keep a home up to 12ºF cooler than black, while in winter, darker tones retain heat, warming interiors by up to 7ºF.
Since each degree of temperature change can impact energy use by about 3%, this seasonal color shift can cut heating and cooling needs by up to 25%.
Winter
Dark Paint > Absorbs Heat > Warms Building
Summer
Light Paint > Reflects Heat > Cools Building
The formulation is smart and durable: below 77ºF (25ºC), it appears deep grey; above that, it shifts almost instantly to white. It can also be tinted—imagine a home that transitions from light blue in summer to navy in winter.
Beyond homes, this paint could benefit schools, factories, and other large structures—quietly adapting to the climate, just like nature intended.
