Amended IN Assembly March 21, 2019 CALIFORNIA LEGISLATURE 20192020 REGULAR SESSION Assembly Bill No. 660Introduced by Assembly Member LevineFebruary 15, 2019An act relating to energy. An act to add Section 25402.13 to the Public Resources Code, relating to energy.LEGISLATIVE COUNSEL'S DIGESTAB 660, as amended, Levine. Building energy efficiency standards. 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 state the intent of the Legislature to enact legislation that would require the commission, commencing in 2020, to remove obstacles to selecting light-colored, cool roof materials for steep-sloped roofs and that would require the commission to consider increasing the minimum aged solar reflectance requirement for steep-sloped roofs on both new and existing nonresidential and residential buildings across California and for low-slope roofs on high-rise residential buildings by 2030.This bill would require the commission to increase the minimum aged solar reflectance requirements for steep roofs and for low-slope roofs on high-rise residential buildings, to take effect on January 1, 2030, to unspecified amounts. The bill would authorize the commission to exempt buildings in certain climate zones from these requirements if it determines that the increase in the minimum aged solar reflectance requirements would not be cost effective in those particular climate zones.Digest Key Vote: MAJORITY Appropriation: NO Fiscal Committee: NOYES Local Program: NO Bill TextThe people of the State of California do enact as follows:SECTION 1. Section 25402.13 is added to the Public Resources Code, to read:25402.13. (a) To mitigate the urban heat island effect consistent with the strategies for cool roofs developed pursuant to Section 71400, the commission shall do both of the following in regulations adopted pursuant to Section 25402:(1) Increase the minimum aged solar reflectance requirement for steep roofs to ____.(2) Increase the minimum aged solar reflectance requirement for low-slope roofs on high-rise residential buildings to ____.(b) The commission may exempt buildings in certain climate zones from the requirements adopted pursuant to subdivision (a) if the commission determines that the increase in the minimum aged solar reflectance requirements would not be cost effective in those particular climate zones.(c) Regulations adopted pursuant to this section shall take effect on January 1, 2030.SECTION 1.It is the intent of the Legislature to enact legislation that would require the State Energy Resources Conservation and Development Commission, commencing in 2020, to remove obstacles to selecting light-colored, cool roof materials for steep-sloped roofs and that would require the commission to consider increasing the minimum aged (long term) solar reflectance requirement for steep-sloped roofs on both new and existing nonresidential and residential buildings across California (building climate zones 1 to 16, inclusive) and for low-slope roofs on high-rise residential buildings by 2030.
