A research team from Southeast University in Nanjing, the University of Chicago, and Purdue University in Indiana has developed a cement that passively cools buildings.
It reflects sunlight and releases heat in the infrared spectrum. In field tests, the surface stayed up to 5.4 Ā°C cooler than the surrounding air under strong sun, and around 26 Ā°C cooler than conventional cement. The material is durable, inexpensive to produce, and can be applied as a coating or used directly in construction. It could reduce the need for air conditioning, ease the load on power grids, and help cut urban heat.
