Title 24 California Climate Zones 1-16

The California climate zones range from Zone 1, which includes areas with the warmest temperatures, to Zone 16, which includes areas with the coolest temperatures. Each zone is characterized by a unique set of climate-related variables, such as temperature, humidity, and wind patterns.

The climate zone in which a building is located can have a significant impact on its energy use. For example, buildings in warmer climates may require more cooling, while buildings in cooler climates may require more heating. envelope insulation requirement will change based on climate zone, By taking into account these climate-related variables and tailoring energy use accordingly, buildings can be constructed to be more energy-efficient and cost-effective while also reducing their impact on the environment.
