Imagine your home could stay cool without cranking the AC—that’s exactly what this new cement-based paint does. Developed by scientists in Singapore, the innovative coating combines three forms of passive cooling: reflecting sunlight, radiating heat, and evaporating stored water—like your skin sweats to cool down.

Here’s how it works: the paint reflects up to 92% of sunlight even when wet and emits 95% of absorbed heat as infrared radiation, channeling it into the sky. Its porous structure holds moisture—almost 30% of its weight—and slowly releases it to drive evaporative cooling. Field tests in tropical Singapore showed homes painted with this formula used 30–40% less electricity for air conditioning, and after two years of exposure, it kept its brilliant white color while conventional paints yellowed.

With around 60% of buildings’ energy used for cooling, this paint offers a powerful, low-energy solution. Its durability, self-cleaning properties, and ability to reduce urban heat islands make it ideal for hot, humid cities. It’s a simple, scalable innovation that can help cool homes, cut energy bills, and fight climate change—one coat at a time.
