Berkeley Lab built a roof coating of vanadium dioxide that flips at 67°C; across 15 US climate zones, it outperformed existing coatings in 12 and cut household electricity by 10%

A team of researchers has introduced an innovative roof coating designed to respond to changing seasonal temperatures. This cutting-edge material ensures homes are cooler in hot months and warmer in cold ones. Preliminary results indicate that it significantly outperforms existing cool roof technologies. With the potential to reduce electricity consumption in households by ten percent, this invention addresses the urgent challenges of global cooling energy needs.
