Title 24 Energy-Efficiency Standards: How It Differs from Title 20 Requirements  

Title 24 and JA8: Some Background

Title 24 is the state of California’s building code. Part 6 of Title 24 is the energy code, which includes energy-specific requirements for the installation of lighting – to promote energy efficiency in buildings and building sites throughout the state. These requirements address:

• Lighting Power Allowances – The maximum lighting power in watts allowed for a building project, including project area and lighting power density;  
• Lighting controls – Specific controls must be installed to provide energy-saving functionality, such as automatic shut off, daylighting response and dimming.

Title 24 compliance is enforced for new and refurbished buildings that require permit reviews and inspections to obtain a certificate of occupancy. Every three years, the California Energy Commission updates the building energy-efficiency standards in Title 24 by working directly with stakeholders to make improvements.

Joint Appendix 8 (JA8) is a specific reference to the performance requirements for high luminous efficacy light sources within Title 24. These requirements must be met for light sources (including LED lamps) to be installed in single family and multi-family residential buildings in California. To qualify for Title 20/Title 24 JA8 compliance, each lamp must be listed in California’s MAEDBS (Modernized Appliance Efficiency Database System).
