The mandatory features and devices are required for all sign lighting projects as applicable. The mandatory measures require that lighting controls are certified by the manufacturers to the Energy Commission, and that sign lighting systems have controls for efficient operation. Mandatory features also set requirements for how lighting systems are classified according to technology, and how to calculate installed wattage.
Mandatory measures for signs are specified in §110.9, §110.12, §130.0, and §130.3. These mandatory measures for signs are similar to the mandatory measures for the other indoor and outdoor lighting Standards.
Note: For projects that involve building plans, the person with overall responsibility must ensure that the Mandatory Measures that apply to the project are listed on the plans. The format of the list is left to the discretion of the Principal Designer.
A. A lighting control system shall comply with all requirements listed below, and all components of the system considered together as installed shall meet all applicable requirements for the lighting control application for which they are installed:
•Before a lighting control system, including an energy management control system (EMCS), can be recognized for compliance with the lighting control requirements in the Energy Standards, the person who is eligible under Division 3 of the Business and Professions Code to accept responsibility for the construction or installation of features, materials, components, or manufactured devices shall sign and submit an Installation Certificate (§130.4(b) 1 and 2).
•If any of the requirements in the Installation Certificate fail the installation tests, the Lighting Control System (or EMCS) shall not be recognized for compliance with the Energy Standards.
B. Lighting Control Functionality:
All Installed Lighting Controls listed in §110.9(b) shall comply with the requirements listed below. In addition, all components of the system considered together as installed shall meet all applicable requirements for the application for which they are installed as required in §130.0 through §130.5, §140.6 through §140.8, §141.0, and §150.0(k)
Designers and installers are advised to review features of their specified lighting control products for meeting the requirements of Section 110.9(b) as part of the code compliance process.
1. Time-Switch Lighting Controls
Time-switch lighting control products shall provide the functionality listed in Section 110.9(b)1 of the Energy Code.
2. Daylighting Controls
Daylighting control products shall provide the functionality listed in Section 110.9(b)2 of the Energy Code.
3. Dimmer
Dimmer products shall provide the functionality listed in Section 110.9(b)3 of the Energy Code.
Occupant sensing control products (including occupant sensors, partial-ON occupant sensors, partial-OFF occupant sensors, motion sensors, and vacancy sensor controls) shall provide the functionality listed in Section 110.9(b)4 of the Energy Code.
One important functionality is to be capable of automatically turning the lights either off or down within 20 minutes after the area has been vacated.
EXCEPTION to the requirement: occupant sensing control systems may consist of a combination of single or multi-level occupant, motion, or vacancy sensor controls, provided that components installed to comply with manual-on requirements shall not be capable of conversion by occupants from manual-on to automatic-on functionality.
5. Part-Night Outdoor Lighting Controls
Part-night outdoor lighting control products shall provide the functionality listed in Section 110.9(b)5 of the Energy Code.
The lighting wattage of signs shall be determined in accordance with the applicable provisions of §130.0(c). Note that the installed wattage of sign lighting is not considered when using the Alternate Lighting Source compliance option in §140.8(b). See Section 7.4 of this chapter for more information about sign lighting energy requirements.
Following are the most common sign lighting requirements for determining luminaire classification and power:
1. The wattage of luminaires with line voltage lamp holders not containing permanently installed ballasts or transformers shall be the maximum relamping rated wattage of the luminaire, and for recessed luminaires with line-voltage medium screw base sockets, wattage shall not be less than 50 watts per socket.
2. Screw-based adaptors shall not be used to convert an incandescent luminaire to any type of non-incandescent technology. Screw-based adaptors, including screw-base adaptors classified as permanent by the manufacturer, shall not be recognized for compliance with the Energy Standards.
3. The wattage of luminaires with permanently installed or remotely installed ballasts or drivers shall be the operating input wattage of the rated lamp/ballast combination published in ballast manufacturer’s catalogs based on independent testing lab reports as specified by UL 1598.
4. The wattage of luminaires and lighting systems with permanently installed or remotely installed transformers shall be the rated wattage of the lamp/transformer combination.
5. The wattage of light emitting diode (LED) luminaires, and LED light engines shall be the maximum rated input wattage of the system when tested in accordance with IES LM-79-08.
The rules for determining lighting wattage are discussed in greater detail in Chapter 5 of this manual.
