The California Energy Code defines the diversity of California's climate in sixteen climate zones. Additionally, several efficiency standards, such as those for envelope and fenestration (window and door) materials, vary depending on the specific climate zone that the building is located in. As a result, it is crucial for builders and building officials to know which climate zones apply to their projects. To determine your zone location, you can check the EZ Building Climate Zone Finder available on arcgis.com.
