California Title 24 Building Energy Efficiency Standards require cool roofs (high solar reflectance) on most new and re-roofed Oakland buildings, reducing urban heat island and supporting ECAP climate goals while cutting cooling costs.
California Title 24, Part 6 prescribes cool-roof minimum aged solar reflectance and thermal emittance for low-slope and steep-slope roofs in Climate Zone 3 (Oakland). Re-roofing replacing more than 50 percent of roof area triggers compliance for nonresidential and high-rise residential buildings; low-rise residential cool-roof rules vary by climate zone and are prescriptive in some, advisory in others. Oakland building permits verify compliance via Cool Roof Rating Council labeled products. Cool roofs reduce attic temperatures, AC load, and citywide heat island, complementing ECAP and Bay Area heat-island mitigation.
Permit denial or stop-work order for non-compliant materials; certificate-of-occupancy delay; CRRC label required at inspection; corrections at owner expense.
