Radiative cooling paint could reduce air-con load

Nissan, in collaboration with Malaysian radiative cooling specialist Radi-Cool, has developed a revolutionary paint technology and proven it can significantly reduce vehicle interior temperatures, reducing the load on cabin comfort air-conditioning with the potential for other applications such as transport refrigeration and other thermal management solutions.

“This is especially important in the EV era, where the load from running air conditioning in summer can have a sizable impact on the state of charge,” said Dr. Susumu Miura, senior manager and expert at the Advanced Materials and Processing Laboratory, Nissan Research Centre.

Core to this technology is metamaterial, a type of synthetic substance engineered to have properties rarely observed in the natural world, featuring two distinct microstructures embedded within the paint that react to light.
