What does the Energy Star rating recognize?

The Energy Star rating specifically recognizes the albedo, which is a measure of reflectivity. In the context of roofing materials, a higher albedo indicates that a roof can reflect more sunlight and absorb less heat, which contributes to energy efficiency and helps to reduce cooling costs in buildings. Roofs with high reflectivity can significantly lower the temperature of the roof surface and surrounding environment, promoting energy savings and reducing the urban heat island effect. This focus on reflectivity aligns with Energy Star's goals to encourage the use of products that enhance energy conservation and environmental benefits.
