Nissan is currently testing a new cool paint technology
Embedded metamaterial helps lower cabin temperatures and reduce energy usage, taking the heat out of summer.
September 02, 2024
Nissan has been testing a groundbreaking automotive paint designed to reduce a vehicle's interior temperature in summer and decrease the need for air conditioning. Developed in collaboration with Radi-Cool, a specialist in radiative cooling products, the paint contains metamaterial - synthetic materials with unique properties.
This project is part of Nissan's commitment to innovative solutions that enhance journeys and contribute to a cleaner, more sustainable society. In November 2023, Nissan began a 12-month trial at Tokyo International Air Terminal at Haneda, partnering with Japan Airport Terminal Co., Ltd., Radi-Cool Japan, and All Nippon Airways (ANA) airport services. They applied the cool paint to a Nissan NV100 service vehicle.
Haneda airport's open tarmac provided an ideal setting for testing the paint's performance in high temperatures. Results have shown significant temperature reductions on both the exterior and interior of vehicles treated with Nissan's cool paint compared to traditional paint.
The paint's unique cooling capabilities are beneficial for energy efficiency and passenger comfort, especially in hot climates. The metamaterial in the paint utilizes microstructure particles to reflect and redirect sunlight, reducing heat absorption by surfaces like the roof and doors.
Leading the development is Dr. Susumu Miura, an expert at Nissan Research Center, who aims to create energy-efficient and comfortable vehicles. Despite challenges, including developing a spray-on application and meeting quality standards, the team continues to refine the paint for potential future integration into commercial vehicles like vans and trucks.
