Abstract or Description
California’s diverse geography led the California Energy Commission (CEC) to divide the state into 16 Climate Zones, each reflecting local weather patterns and energy demands. These zones guide energy-efficient building standards by setting energy budgets tailored to regional conditions. This fact sheet explains the role of climate zones in shaping energy policy, using San Diego County’s four distinct zones as an example of how local climates influence building code requirements.
