Each Climate zone has a unique climatic condition that dictates which minimum efficiency requirements are needed for that specific climate zone. The California climate zones shown in this map are not the same as what we commonly call climate areas such as &quot;desert&quot; or &quot;alpine&quot; climates. The climate zones are based on energy use, temperature, weather and other factors.</div><div style='font-family:inherit;'><br /></div><div style='font-family:inherit;'>This is explained in the Title 24 energy efficiency standards glossary section:</div><div style='font-family:inherit;'><br /></div><div style='font-family:inherit;'>&quot;The Energy Commission established 16 climate zones that represent a geographic area for which an energy budget is established. These energy budgets are the basis for the standards....&quot; &quot;(An) energy budget is the maximum amount of energy that a building, or portion of a building...can be designed to consume per year.&quot;</div><div style='font-family:inherit;'><br /></div><div style='font-family:inherit;'>&quot;The Energy Commission originally developed weather data for each climate zone by using unmodified (but error-screened) data for a representative city and weather year (representative months from various years). The Energy Commission analyzed weather data from weather stations selected for (1) reliability of data, (2) currency of data, (3) proximity to population centers, and (4) non-duplication of stations within a climate zone.</div><div style='font-family:inherit;'><br /></div><div style='font-family:inherit;'>&quot;Using this information, they created representative temperature data for each zone. The remainder of the weather data for each zone is still that of the representative city.&quot; The representative city for each climate zone (CZ) is:</div><div style='font-family:inherit;'><br /></div><div style='font-family:inherit;'>CZ 1: Arcata</div><div style='font-family:inherit;'>CZ 2: Santa Rosa</div><div style='font-family:inherit;'>CZ 3: Oakland</div><div style='font-family:inherit;'>CZ 4: San Jose-Reid</div><div style='font-family:inherit;'>CZ 5: Santa Maria</div><div style='font-family:inherit;'>CZ 6: Torrance</div><div style='font-family:inherit;'>CZ 7: San Diego-Lindbergh</div><div style='font-family:inherit;'>CZ 8: Fullerton</div><div style='font-family:inherit;'>CZ 9: Burbank-Glendale</div><div style='font-family:inherit;'>CZ10: Riverside</div><div style='font-family:inherit;'>CZ11: Red Bluff</div><div style='font-family:inherit;'>CZ12: Sacramento</div><div style='font-family:inherit;'>CZ13: Fresno</div><div style='font-family:inherit;'>CZ14: Palmdale</div><div style='font-family:inherit;'>CZ15: Palm Spring-Intl</div><div style='font-family:inherit;'>CZ16: Blue Canyon</div><div style='font-family:inherit;'>The original detailed survey definitions of the 16 Climate Zones are found in the 1995 publication, &quot;California Climate Zone Descriptions for New Buildings.&quot; </div></div>
