Cool‐Colored Cars; a New Technology to Reduce Air‐ConditioningLoad

Energy management in modern vehicles is a crucial issue, because of reducing natural resources and increasing prices,especially in recent years. Use of air conditioning in cars decreases fuel economy and increases tailpipe emissions of greenhouse gases and air pollutants, contributing to global climate change and smog formation in cities.The adoption of solar reflective coatings for opaque surfaces of the vehicle shell can decrease the soaktemperature of the air in the cabin of a vehicle parked in the sun, potentially reducing the vehicle’sair conditioning load and improving its fuel economy by permitting the use of a smaller air conditioner.
