For a residential building in California Climate Zone 13, what is the minimum aged solar reflectance requirement for a low-sloped roof under Title 24?
Correct Answer
A) 0.63 aged solar reflectance
Title 24, Part 6, Section 150.1(c)3 requires cool roofs with minimum aged solar reflectance of 0.63 for low-sloped roofs in most California climate zones. This requirement reduces cooling energy consumption and urban heat island effects. Climate Zone 13 (inland areas) specifically requires this reflectance value for energy efficiency compliance.
Why This Is the Correct Answer
