California Title 24 Overview


Digital Lumens SiteWorx Tune Intelligent LED Lighting System and the California Energy Efficiency Standard

Title 24 Smart Lighting Requirements

Beginning July 1, 2014, pursuant to Title 24, Section 6, Part 130.1, all commercial and industrial building lighting systems shall have:

Manual Continuous Dimming and on/off Control: Manual lighting controls must be accessible on a room-by-room basis, to give occupants the ability to change lighting behavior throughout the day or shift, as their work patterns and needs change.

• The Digital Lumens SWN-KPD Lighting Control Keypad is wall-mounted with four configurable buttons that each trigger a unique, pre-programmed lighting profile. Easy to install, configure, and use, the SWN-KPD allows users on the building floor to instantly activate preset profiles.

Task Tuning: Task tuning is the ability to cap a light fixture’s light output at a level less than 100% because full power is not necessary to sufficiently illuminate a particular space.

• SiteWorx Tune allows users to configure Digital Lumens’ intelligent LED luminaires to lighting levels anywhere from 0 to 100% of maximum output.

Occupancy Sensors: Occupancy sensors are required in corridors and stairwells, aisles and open areas in warehouses, offices ≤250 ft2, conference rooms of any size, multi-purpose rooms <1000 ft2, and classrooms of any size, and lighting in these areas must be dimmed during unoccupied periods.

• Every Digital Lumens intelligent LED luminaire utilizes a high-performance occupancy sensor and full-range, 0-100% digital dimming to provide maximum efficiency in a variety of environments.

Required Shutoff: In areas of buildings that are not occupied 24/7, facility managers will no longer be able to leave the lights on at all times.

• The SiteWorx Tune lighting and energy management system utilizes Setback function to shutoff fixtures, making it easy for facility managers to configure lights to turn off during periods when an area is empty. Occupancy sensors remain active in the event that workers need unscheduled access to an area, and will trigger occupancy-based illumination.

Daylight Harvesting: Daylight harvesting is the ability to automatically dim artificial lighting based on the amount of natural light detected in a room or area. To achieve Title 24 compliance, daylight harvesting capability is required in both primary and secondary side-lit areas.

• The Digital Lumens intelligent LED Luminaires feature integrated photo sensors, which continually assess available ambient light and automatically adjust light output, even dimming completely, to ensure desired light levels at the floor level and maximize efficiency.

Automated Demand Response: All commercial buildings 10,000 ft2 and larger must include lighting controls that are compatible with the local utility’s DR protocol. Building operators are responsible for programming the lighting controls to automatically reduce lighting power consumption in response to DR signals.

• Digital Lumens SiteWorx Tune lighting and energy management system enables facilities to switch over to a Demand Response lighting profile at a moment’s notice.
Please note: SiteWorx Tune and additional third-party integration may be necessary. Please contact Digital Lumens for more information.

In summary, the Digital Lumens SiteWorx Tune and intelligent LED Luminaires, with fully integrated energy-saving controls, fully supports the California Energy Commission’s Title 24 standards. There is no better solution for ensuring that your existing building or new construction project is in line with California’s long-term energy efficiency strategy.
