California reach code for cool roofs and solar PV

Description: Brisbane, CA adopted a local amendment to California’s 2016 Title 24 Building Efficiency Standards. The amendment requires installing cool roofs (reflective roofing that reduces sunlight absorbed by buildings) and solar photovoltaics (PV) or solar hot water systems in all new non-residential, residential, and mixed-use buildings or renovations exceeding 50 percent of the floor area of the pre-existing building. Cool roofs can benefit the environment by reducing local air temperatures and curbing power plant emissions by reducing the need for energy to cool buildings.

Los Angeles adopted a Cool Roof Ordinance in 2014.

Goal: California Reach Code for cool roofs and solar PV or solar hot water usage

Measurement: Percentage decrease in energy use compared to California Title 24 standards

Time to Implement:
