California Energy Commission (CEC) Title 20 and Title 24, Part 6
Title 20 and Title 24 have been directed by the California Energy Commission (CEC) and are updated regularly over a specific period of time, once the decisions are made through a ruling process, the updated version is declared as mandatory in California.
WHAT IS TITLE 24, PART 6?
Established in 1978 as a solution due to California’s growing energy consumption, California Title 24 highlights the introduction of energy requirements for residential and non-residential buildings in California. For example, Title 24 states that High Efficacy Luminaires are mandatory in specific locations and in specific quantities in newly built houses and in key residential renovations.
As for other examples, Title 24 says that:
In residential areas, each of the lights which are installed must be high efficacy luminaires and should be controlled by vacancy sensors in attached and detached garages, laundry rooms, and utility rooms.
Apart from the main rooms, the installed lighting should either be high efficacy luminaires or be regulated by a vacancy sensor or a dimmer, i.e. the rooms other than bathrooms, the kitchen, garages, laundry rooms, closets, or utility rooms.
Required non-residential indoor lighting controls include:
1. Area Controls: Manually controls lighting in each area on an individual basis.
2. Multi-Level Controls: Enables the occupants in an area with the facility to use the lights on either a full, half, quarterly basis or none at all.
3. Shut-off Controls: Automatically shuts off or reduces the brightness or the light output when not in use.
4. Automatic Daylighting Controls: Separately controls some or all lights in the outdoor (in the daylight zone) area from the lights that are not in the outdoor area.
5. Demands Responsive Lighting Controls: Installs controls which contain the feature of receiving and responding to a ‘demand response’ signal.
What is Title 20?
The California Energy Commission Title 20 is part of the Appliance Efficiency Regulation and California Code of Regulations. Title 20 states that a manufacturer certification of lighting control devices in California is required, which, in turn refers to distinct lighting control products that can perform their designated function without an additional connection to other devices.
As for Lighting Control Systems, which refers to those products/devices that require an additional connection of a separate module to provide lighting control, can’t be applied to Title 20 and have not been listed in the online database.
For example, common devices that can be considered as under the respective category include:
• Self-contained Automatic Daylighting Controls
• Line powered Occupancy Sensors
• Line power Vacancy Sensors
The manufacturer is required to provide a declaration that the information provided about the submitted products is precise. After each submission is reviewed by The CEC, it enables an online database that helps in finding the list of approved Title 20 products by the manufacturer or by their technological identity.
