Illinois researchers tested a passive cooling film in Houston; treated metal roofs measured more than 40°F cooler in direct sunlight

As American summers heat up, public health risks escalate, prompting researchers to create an innovative coating that cools metal roofs by over forty degrees. This technology was implemented on public structures in Houston in anticipation of a significant global sports event. Remarkably, it works by reflecting sunlight and dissipating heat without consuming electricity, marking a significant step forward in sustainable urban cooling solutions.
