Two vehicles -- one black one silver, parked on the pavement and in the sun.
October 17th 2011
Nearly all cars sold in California have air conditioners. Cars painted with reflective coatings stay cooler in the sun and are easier to air condition to a comfortable temperature, according to a recent study by researchers in Berkeley Lab's Environmental Energy Technologies Division. "Solar reflective paints can decrease the ‘soak' temperature of the air in a car that has been parked in the sun. This could improve the vehicle's fuel economy by... Read More
