These standards are designed to reduce energy consumption in residential and nonresidential buildings across California. Title 24 is part of the California Code of Regulations and includes:
Part 6: The Energy Code, which sets mandatory energy efficiency requirements for new buildings and renovations.
Part 11: CALGreen, which includes voluntary energy efficiency measures
A: California Building Standards Commission created California Energy Code Title 24 (CEC Title 24) in 1978 to reduce the state’s energy consumption through legislation.
A: California Energy Code Title 24 requires that each service or feeder must have a permanently installed metering system that measures electrical energy.
“Electrical power distribution systems shall be designed so that measurement devices can monitor the electrical energy usage of load types. The maximum combined voltage drop on both installed feeder conductors and branch circuit conductors to the farthest connected load or outlet shall not exceed 5 percent.”
For more detailed information, you can refer to the specific sections and tables (160.6(a) through 160.6(e)) of the California Energy Code that address these requirements.
A: Depending on the size of the building and the electrical rating of the service entrance (or common use areas), different metering functionality is required.
A: For many buildings, submetering is required to determine how much energy is being used towards particular loads. The specific requirements vary depending on the service-entrance rating.
A: Non-compliance with CEC Title 24 can result in various penalties:
Product Standards: The CEC has the authority to impose penalties for violating the appliance efficiency standards. The factors considered when determining an appropriate penalty are set by the Public Resources Code section 25402.11 and Title 20 California Code of Regulations (section 1609).
Thermal Power Plants: The CEC can impose penalties for noncompliant thermal power plants with a generating capacity of 50 megawatts or more, and any related facilities. This is provided by the Public Resources Code section 25534 (b).
Permitting Process: If non-certified forms are submitted, they will not be accepted and will likely hold up the permitting process, causing project delays. Contractors that cannot submit certified forms and are found to be holding up the Temporary Certificate of Occupancy can also face costly contract fees.
It’s recommended that regulated entities monitor all product lines and facilities to ensure compliance with the state’s energy and water efficiency standards.
