What is Title 24, Part 6?
Title 24, Part 6 is the California Energy Code, the Building Energy Efficiency Standards adopted by the California Energy Commission. It sets requirements for new buildings, additions and alterations, covering envelope, HVAC, lighting, water heating, controls and demand response readiness.
What it is
Part 6 of Title 24 of the California Code of Regulations is updated on a regular code cycle. Each cycle raises efficiency expectations and adds requirements, often in controls, electrification readiness and solar and storage.
For nonresidential buildings, the standards include lighting controls, HVAC controls and demand responsive controls that allow a building to reduce load in response to a signal. Compliance is shown through prescriptive or performance approaches, with acceptance testing to confirm that installed systems work.
Who it applies to / where it is used
Title 24, Part 6 applies to building projects in California, including new construction and many alterations. Architects, MEP engineers, contractors, acceptance test technicians and building departments all work with it. Check the current code cycle for the requirements that apply.
How it is measured / what evidence it needs
Compliance documentation is completed at permit and construction. Acceptance tests confirm that controls operate as designed at handover.
- Compliance forms for the chosen approach
- Acceptance test records for controls and HVAC
- Demand responsive control capability where required
- Operating evidence that schedules and setpoints hold after handover
How Aqueduct helps
Aqueduct maps Title 24 demand response and controls readiness to peak demand management and setpoint optimization in operation.
- Peak demand tracking and load shifting through aQ EnergySmart
- Setpoint and schedule changes where control is enabled, with owner approval
- Fault detection when controls drift from the sequence that passed acceptance
- Measured verification of every change at the meter
