Under California Title 24 energy efficiency standards, what is the minimum aged solar reflectance requirement for cool roof materials on low-sloped roofs in Climate Zone 2?
Correct Answer
D) 0.63
Title 24, Part 6, Section 150.1(c)1 requires cool roof materials in Climate Zone 2 to have a minimum aged solar reflectance of 0.63 and thermal emittance of 0.75. These requirements help reduce cooling energy consumption and urban heat island effects in California's diverse climate zones.
