Title 24 – 2006 – California Code of Regulations for Energy Efficiency
Title 24 is a portion of the California Code of Regulations that pertains to energy efficiency standards in the construction of residential and non-residential buildings. It was enacted in 1978 (Warren- Alquist Act) in response to a legislative mandate to reduce California’s energy consumption. The California Energy Commission (CEC)put this ruling into effect to reduce energy bills, to increase energy delivery system reliability and to contribute to an improved economic condition for the state. Since 1978, several amendments were made to update energy standards as a reflection of improvements in energy technology and energy conservation. Effective October 1, 2005, the CEC updated Title 24 standards to further reduce California’s energy consumption. Starting on this date, when a CA homeowner is changing out the heating or air-conditioning (HVAC) equipment (the air handler, the outdoor condenser of a split air-conditioner or heat pump, cooling or heating coil, or the furnace heat exchanger) in an existing house, contractors in certain climate zones will be required to test the ducts for leakage and seal the leaking ducts. Third-party field verification by a certified home energy rater (HERS – Home Energy Rating Service) is also required to insure that the duct sealing is accomplished according
