As an important heat exchange interface in buildings, the roof’s cooling performance directly affects the comfort level and energy consumption in buildings. This paper introduces the basic principle of high reflectance aluminum roof, which utilizes the high reflectance property of aluminum to reflect most of the solar radiation back into the atmosphere, reducing the amount of solar radiation absorbed by the roof. The paper discusses the cooling performance of high reflectance aluminum roof as a roof material.
