With the steady increase in CO2 emissions, and global warming firmly on the rise, it is estimated that cities around the world will see a 5-degree Celsius temperature increase by 2050, an event that will further tamper with an already faltering ecosystem.

Spectrum is a thermochromic paint that changes its color based on temperature. It is designed to be applied to the roofs of buildings and reflect the heat during the warmer seasons while absorbing it in the cooler months, thereby improving energy efficiency. Spectrum is an economical passive cooling solution that allows for energy savings of over 15%. Used over an entire cityscape, it is capable of decreasing the average outdoor temperature by 3 degrees Celsius.

Watch Willy Camou, the generalist engineer on the Spectrum team, speak about this cutting-edge solution to a global problem and the invaluable support they received at the Global Grad Show Acceleration Program.
