Burbank Municipal Code Div. 1 Green Building and Sustainable Architecture

Part 11 of Title 24 of the California Code of Regulations, also known as the “California Green Building Standards Code,” which is part of the California Building Standards Code, 2025 Edition, as adopted by the California Building Standards Commission, is hereby adopted and made a part of this Code, with certain amendments, additions, and deletions as stated in this Article. [Added by Ord. No. 25-4,034, eff. 1/1/26.]

9-1-11-4.509: COOL ROOF FOR REDUCTION OF HEAT ISLAND EFFECT:

The following section is added to Chapter 4, Part 11 of the CBC to read as follows:

9-1-11-4.509: Cool roof for reduction of heat island effect.

Roofing materials shall comply with the solar reflectance and thermal emittance requirements of this section.

Exceptions:

1. Roof repair

2. Installation of building-integrated photovoltaics

3. Roof construction that has a thermal mass over the roof membrane, including areas of vegetated (green) roofs, weighing at least 25 pounds per square foot

A. Solar Reflectance

Roofing materials shall have a minimum 3-year aged solar reflectance equal to or greater than the values specified in Table 4.509(1) and Table 4.509(2)

B. Thermal Emittance

Roofing materials shall have a Cool Roof Rating Council initial or aged thermal emittance equal to or greater than the values specified in Table 4.509(1) and Table 4.509(2)

C. Solar Reflective Index Alternative

Roofing materials having a Solar Reflectance Index (SRI) equal to or greater than the values specified in Table 4.509(1) and Table 4.509(2) may be used as an alternative to compliance with the 3-year aged solar reflectance and thermal emittance values.

9-1-11-5.509: COOL ROOF FOR REDUCTION OF HEAT ISLAND EFFECT:

The following section is added to Chapter 5, Part 11 of the CBC to read as follows:

9-1-11-5.509: Cool roof for reduction of heat island effect.

Roofing materials shall comply with the solar reflectance and thermal emittance requirements of this section.

Exceptions:

1. Roof repair

2. Installation of building-integrated photovoltaics

3. Roof construction that has a thermal mass over the roof membrane, including areas of vegetated (green) roofs, weighing at least 25 pounds per square foot

A. Solar Reflectance

Roofing materials shall have a minimum 3-year aged solar reflectance equal to or greater than the values specified in Table 5.509

B. Thermal Emittance

Roofing materials shall have a Cool Roof Rating Council initial or aged thermal emittance equal to or greater than the values specified in Table 5.509

C. Solar Reflective Index Alternative

Roofing materials having a Solar Reflectance Index (SRI) equal to or greater than the values specified in Table 5.509 may be used as an alternative to compliance with the 3-year aged solar reflectance and thermal emittance values.
