CALIFORNIA LEGISLATURE— 2019–2020 REGULAR SESSION

Assembly Bill
No. 660


Introduced by Assembly Member Levine

February 15, 2019


An act to add Section 25402.14 to the Public Resources Code, relating to energy.


LEGISLATIVE COUNSEL'S DIGEST


AB 660, as amended, Levine. Building energy efficiency standards: solar reflectance of roofs.
Existing law authorizes the State Energy Resources Conservation and Development Commission to prescribe, by regulation, energy efficiency standards, including appliance efficiency standards. Under this authorization, the commission has adopted requirements for thermal emittance, 3-year aged reflectance, and solar reflectance index of roofing materials used in new construction and reroofing projects.
This bill would require the commission, during each one or more of the next 4 triennial code adoption cycles after January 1, 2020, to consider amendments to the roof replacement building standards for alterations to existing low-rise low-rise, steep-sloped roof residential buildings to achieve with the goal of increasing the value of minimum aged solar reflectance from 0.20 in the 2019 standard to between 0.25 and 0.30 in the 2025 standard and to between 0.35 and up to 0.45 in the 2031 standard and the goal of expanding the range of climate zones in which minimum aged solar reflectance values are prescribed for those alterations. The bill would require the commission, prior to considering these amendments, to assess whether there is an adequate supply of labor resources and available compliant products in the climate zones for which the commission may consider the amendments. The bill would also require that the amendments be cost-effective and not be imposed on existing low-rise, steep-sloped roof residential buildings where the cost of compliance would exceed the actual energy cost savings achieved through compliance.
Vote: MAJORITY   Appropriation: NO   Fiscal Committee: YES   Local Program: NO  

The people of the State of California do enact as follows:


SECTION 1.

 Section 25402.14 is added to the Public Resources Code, to read:

25402.14.
 (a) During each one or more of the next four triennial code adoption cycles after January 1, 2020, the commission shall consider amendments to the roof replacement building standards for alterations to existing low-rise low-rise, steep-sloped roof residential buildings, to be included in Part 6 (commencing with Section 100) of Title 24 of the California Code of Regulations, to achieve with the goal of increasing the value of minimum aged solar reflectance from 0.20 in the 2019 standard to between 0.25 and 0.30 in the 2025 standard and to between 0.35 and up to 0.45 in the 2031 standard and the goal of expanding the range of climate zones in which minimum aged solar reflectance values are prescribed for those alterations. In determining if such changes shall be made, the commission shall assess whether there is an adequate supply of available compliant product and whether the change will be cost effective over the life of the roof replacement.
(b) Prior to considering amendments to roof replacement building standards pursuant to subdivision (a), the commission shall assess whether there is an adequate supply of labor resources and available compliant products in the climate zones for which the commission may consider these amendments.
(c) Any requirement prescribed pursuant to subdivision (a) shall be cost-effective, as determined pursuant to Section 25402, and shall not be imposed on existing low-rise, steep-sloped roof residential buildings where the cost of compliance would exceed the actual energy cost savings achieved through compliance.
