The following five controls are required in Title 24:

1. Area Controls: Manual controls that control lighting in each area separately.
2. Multi-level Controls: Allow occupants to choose the appropriate light level for each area.
3. Shut-off Controls: Automatically shuts off lighting or reduces light levels when illumination is not needed.
4. Automatic Daylighting Controls: Adjust electric lighting in response to the presence of daylight.
5. Demand responsive controls: Receive and automatically respond to demand response (DR) signals.

All lighting in each area (An “area” is a space enclosed by ceiling-height partitions) must be controlled separately from luminaires in other areas by manual on/off lighting controls that are:

• Readily accessible
• Located in the same room or area as the lighting they control and with the lighting in view
• Able to provide any required dimming or multi-level controls steps in addition to on/off

No. Each luminaire must meet every step of the multi-level control requirement.

1. Title 24 sets a minimum number of control steps and illuminance uniformity requirement for most major luminaire types in TABLE 130.1-A. These requirements are required in addition to any manual, daylight, shut-off or demand response controls.
2. These criteria apply only to general lighting for enclosed areas that:
1. Are at least 100 square feet in size.
2. Have a connected lighting load over 0.5 watts per square foot.
3. Has more than one luminaire or more than two lamps.

1. Automatic shut-off controls turn off the lights when a space is unoccupied.
2. All lighting must be controlled by one or more of the following:
   1. Occupant sensing control.
   2. Automatic time-switch.
   3. Building Energy Management System.
   4. Other control capable of automatically shutting off all lights for vacant periods.
