Spectrum is a reflective thermochromic paint that changes its colour based on temperature.
It is designed to be applied to the roofs of buildings, providing a passive cooling solution and improving the building’s energy efficiency. If the outdoor temperature reaches over 30 degrees Celsius, the paint becomes white, increasing its reflexivity and stopping the building from absorbing heat. Once the temperature drops, the paint returns to its usual dark tone and allows for greater absorption. It is estimated that the application of the paint to a cityscape could lower the average temperature by up to 3 degrees Celsius. The project was one of the participants in Global Grad Show 2019 Entrepreneurship Programme, receiving training and mentorship to accelerate its development as a startup. Spectrum is one of the recipients of A.R.M. Holding funding that supports Global Grad Show projects to go to market.
