Under California Title 24 Part 6, what is the minimum aged solar reflectance requirement for cool roof materials on low-sloped roofs in Climate Zone 2?
Correct Answer
C) 0.55 aged solar reflectance
Title 24 Part 6 Section 150.1(c)11 requires cool roofs on low-sloped roofs to have minimum aged solar reflectance of 0.55 in most California climate zones including Zone 2. This energy efficiency requirement helps reduce cooling loads and urban heat island effects specific to California's climate conditions.
