Some requirements in the nonresidential lighting Standards are classified as “Mandatory Measures,” because they are required regardless of the compliance approach used. There are no alternate options for substituting the Mandatory Measures. There are no options to not comply with the Mandatory Measures.
It is the responsibility of the designer to specify products that meet these requirements. It is the responsibility of the installer to comply with all of the mandatory requirements, even if the plans mistakenly do not. Code enforcement officials, in turn, must check that the mandatory features and specified devices are installed.
The mandatory measures for nonresidential indoor lighting include the following:
•Some functional areas in nonresidential buildings are required to comply with the low-rise residential lighting Standards (Section 5.2.1 of this chapter)
•Certification of manufactured lighting control devices and systems, ballasts, and luminaires (Section 5.2.4 this chapter)
•Compliance with the California Appliance Efficiency Regulations (Title 20) (Section 5.2.3 of this chapter)
•Rules for how luminaires shall be classified according to technology, and how installed lighting power shall be determined (Section 5.3 of this chapter)
•Indoor lighting controls that shall be installed, which include: Area controls, multi-level controls, automatic shut-OFF controls, daylighting controls, and demand responsive controls (Section 5.4 of this chapter)
•Lighting control acceptance testing required (Section 5.4.6 of this chapter)
•Lighting control Certificate of Installations required (Section 5.4.7 of this chapter)
•Although not related exclusively to lighting, there are mandatory measures for electrical power distribution systems, which include the following: Disaggregation of electrical circuits; voltage drop; circuit controls for 120-volt receptacles; specifications for demand responsive controls and equipment; and. specifications for energy management control systems.
See Chapter 8 of this 'manual for additional information about mandatory measures for electrical power distribution systems.
The following function areas in nonresidential, high-rise residential, and hotel/motel occupancies are required to comply with the low-rise residential lighting Standards (§130.0(b)).
1. High-rise residential dwelling units.
2. Outdoor lighting that is attached to a high-rise residential or hotel/motel building, and is separately controlled from the inside of a dwelling unit or guest room.
3. Fire station dwelling accommodations.
4. Hotel and motel guest rooms.
5. Dormitory and senior housing dwelling accommodations.
In buildings containing these residential type functional areas, all other functional areas, such as common areas, shall comply with the applicable nonresidential lighting Standards.
The Standards do not require a builder, designer, owner, operator, or enforcing agency to test any certified device to determine its compliance with minimum specifications or efficiencies adopted by the Commission.
The Standards limit the installation of manufactured lighting equipment, products, and devices as follows:
A. Lighting items that are regulated by the Title 20 Appliance Efficiency Regulations
Installation shall be limited to those that have been certified to the Energy Commission by their manufacturer, pursuant to the provisions of Title 20 Cal. Code of Regulations, §1606, to meet or exceed minimum specifications or efficiencies adopted by the Commission.
Once a device is certified, it will be 'listed in the Directory of Automatic Lighting Control Devices, which is available from the link below:
Call the Energy Hotline at 1-800-772-3300 to obtain more information.
B. Lighting products required to be Certified to the Energy Commission according to Title 24
These products are not regulated by Title 20. Installation shall be limited to those certified by the manufacturer in a declaration, executed under penalty of perjury under the laws of the State of California, that all the information provided pursuant to the certification is true, complete, accurate and in compliance with all applicable provisions of The Standards; and if applicable that the equipment, product, or device was tested under the applicable test method specified in The Standards.
C. Lighting products required to be 'listed in directories or certified by someone other than the Energy Commission
Installation shall limited to those that comply with the following provisions. The certification status of any such manufactured device shall be confirmed only by reference to:
1. A directory published or approved by the Commission; or
2. A copy of the application for certification from the manufacturer and the letter of acceptance from the Commission staff; or
3. Written confirmation from the publisher of a Commission-approved directory that a device has been certified; or
4. A Commission-approved label on the device.
Any appliance regulated by the Appliance Efficiency Regulations, Title 20 California Code of Regulations, §1601 et seq., may be installed only if the appliance fully complies with those regulations. The Title 20 regulations apply to appliances that are sold or offered for sale in California, except those sold wholesale in California for final retail sale outside the state and those designed and sold exclusively for use in recreational vehicles or other mobile equipment.
Lighting products regulated by the California Appliance Efficiency Regulations (Title 20) must be certified to the Energy Commission by the manufacturer before they can be sold or offered for sale in California, or before they can be specified on California building projects subject to the Standards. The California Appliance Efficiency Regulations include requirements for both federally-regulated appliances and non-federally-regulated appliances.
Performance specifications for most lighting controls have been adopted into the California Title 20 Appliance Efficiency Regulations. To be legally sold or offered for sale in California, stand-alone lighting controls covered by the Appliance Regulations must be tested and certified to the California Energy Commission that they comply with the requirement in the standard.
However, there are many networked lighting control systems that can be programmed to do many of the same functions as the certified stand-alone lighting controls. This section describes the requirements for lighting controls. Stand-alone lighting controls must comply with Title 20 and be in the Appliance Regulation database. Built up lighting controls have to comply with the functional requirements in Title 20 standards. The capabilities of these controls are exercised in the acceptance tests required by §130.4
§110.9 has minimum performance requirements for these self-contained lighting control devices which are not covered by the Title 20 appliance efficiency standards ; field assembled lighting control systems; line-voltage track lighting integral current limiters; supplementary overcurrent protection panels for use with track lighting; ballasts for residential recessed compact fluorescent luminaires; and qualifications for residential high efficacy LED luminaires.
The requirements in §110.9 for ballasts used in residential recessed compact fluorescent luminaires, and for residential high efficacy LED luminaires, do not apply to most nonresidential lighting function areas, except for inside dwelling units of high-rise residential, hotel/motel, fire stations, and dormitory/senior housing.
A. Definition of Self-Contained Lighting Control Devices
These are defined by the Standards as unitary lighting control modules that require no additional components to be fully functional lighting controls. Most self-contained lighting controls required to be installed for compliance with the Standards are required to be certified by the manufacturer according to the Title 20 Appliance Efficiency Regulations The following lighting controls are required to be certified to the Energy Commission in accordance with Title 20 (§110.9(b)1-4).:
1. Time-Switch Lighting Controls
•Automatic Time-Switch Controls
•Astronomical Time-Switch Controls
•Multi-Level Astronomical Time-Switch Controls
•Outdoor Astronomical Time-Switch Controls
2. Daylighting Controls
•Automatic Daylight Controls
•Photo Controls
3. Dimmers
•Occupant Sensors
•Motion Sensors
•Vacancy Sensors
B. Requirements for Miscellaneous Lighting Controls Regulated by Title 24
Lighting controls regulated by Title 24, but not regulated by the Title 20 Appliance Efficiency Regulations, shall meet the following requirements:
1. Part-Night Outdoor Lighting Control (§110.9(b)5)
Although Part-Night outdoor lighting controls do not apply to nonresidential indoor lighting Standards, information about these controls has been placed in this chapter so as to not exclude any regulated control types from this discussion.
A Part Night Outdoor Lighting Control is defined by the Standards as a time or occupancy-based lighting control device or system that is programmed to reduce or turn off the lighting power to an outdoor luminaire for a portion of the night. (Note that this lighting control does not apply to nonresidential indoor lighting Standards).
a. The Part-Night Outdoor Lighting Control is not required to be certified by the manufacturer to the Energy Commission.
b. The requirements for a Part-Night Outdoor Lighting Control are as follows:
i. Be able to accurately predict sunrise and sunset within +/- 15 minutes and timekeeping accuracy within five minutes per year; and
ii. Be able to setback or turn off lighting at night as required in §130.2(c), by means of a programmable timeclock or motion sensing device; and
iii. When the setback or turning off is controlled with a timeclock, shall be capable of being programmed to allow the setback or turning off of the lighting to occur from any time at night until any time in the morning, as determined by the user.
2. Track lighting integral current limiter (§110.9(c))
A track lighting current limiter is used to limit the rated power that can go through a section of track lighting. Without the current limiter, the “installed” wattage of long section of track could be excessive and use up all of the allotted lighting power for a space. With track lighting and a current limiter, one can space the track heads far apart and use high efficacy sources in the track heads so it is possible to stay below the rated wattage of the current limiter. If the wattage served by the current limiter exceeds the rated wattage of the current limiter, the current limiter turns off the current to the controlled lighting.
A track lighting integral current limiter shall be recognized for compliance with the Standards only for line-voltage track lighting systems, and only if it meets all of the following requirements:
a. Shall be certified to the Energy Commission by the manufacturer in accordance with the requirements in §110.9(c); and
b. Before a Line-Voltage Track Lighting Integral Current Limiter will be recognized for compliance with the lighting requirements in Part 6 of Title 24, 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 the Certificate of Installation.
c. If any of the requirements fail the Line-Voltage Track Lighting Integral Current Limiter installation test, the Line-Voltage Track Lighting Integral Current Limiter for determining installed lighting power shall not be used for compliance with Title 24; and
d. Shall be manufactured so that the current limiter housing is used exclusively on the same manufacturer's track for which it is designed; and
e. Shall be designed so that the current limiter housing is permanently attached to the track so that the system will be irreparably damaged if the current limiter housing were to be removed after installation into the track. Methods of attachment may include but are not limited to one-way barbs, rivets, and one-way screws; and
f. Shall employ tamper resistant fasteners for the cover to the wiring compartment; and
g. Shall have the identical volt-ampere (VA) rating of the current limiter, as the system is installed and rated for compliance with the Standards clearly marked on all of the following places:
i. So that it is visible for the building officials’ field inspection without opening coverplates, fixtures, or panels; and
ii. Permanently marked on the circuit breaker; and
iii. On a factory-printed label that is permanently affixed to a non-removable base-plate inside the wiring compartment.
h. Shall have a conspicuous factory installed label permanently affixed to the inside of the wiring compartment warning against removing, tampering with, rewiring, or bypassing the device; and
i. Each electrical panel from which track lighting integral current limiters are energized shall have a factory printed label permanently affixed and prominently located, stating the following:
"NOTICE: Current limiting devices installed in track lighting integral current limiters connected to this panel shall only be replaced with the same or lower amperage. Adding track or replacement of existing current limiters with higher continuous ampere rating will void the track lighting integral current limiter certification, and will require re-submittal of compliance documentation to the enforcement agency responsible for compliance with the California Title 24, Part 6 Building Energy Efficiency Standards.”
3. Track Lighting Supplementary Overcurrent Protection Panel (§110.9(d))
A Track Lighting Supplementary Overcurrent Protection Panel is a subpanel that contains current limiters for use with only multiple track lighting circuits.
A Track Lighting Supplementary Overcurrent Protection Panel shall be used only for line-voltage track lighting and shall be recognized for compliance with the Standards only if it meets all of the following requirements:
a. Before a Track Lighting Supplementary Overcurrent Protection Panel will be recognized for compliance with the lighting requirements in Part 6 of Title 24, 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 the Certificate of Installation.
b. If any of the requirements in the Certificate of Installation fail the installation tests, the Track Lighting Supplementary Overcurrent Protection Panel shall not be recognized by the Standards for determining installed lighting power.
c. Shall be 'listed in accordance with Article 100 of the California Electric Code.
d. Shall be used only for line voltage track lighting. No other lighting or building power shall be used in a Supplementary Overcurrent Protection Panel, and no other lighting or building power shall be recognized for compliance with the Standards by using a Supplementary Overcurrent Protection Panel
e. Be permanently installed in an electrical equipment room, or permanently installed adjacent to the lighting panel board providing supplementary overcurrent protection for the track lighting circuits served by the supplementary over current protection pane; and
f. Shall have a permanently installed label that is prominently located stating the following:
"NOTICE: This Panel for Track Lighting Energy Code Compliance Only. The overcurrent protection devices in this panel shall only be replaced with the same or lower amperage. No other overcurrent protective device shall be added to this panel. Adding to, or replacement of existing overcurrent protective device(s) with higher continuous ampere rating, will void the panel listing and require re-submittal of compliance documentation to the enforcement agency responsible for compliance with the California Title 24, Part 6 Building Energy Efficiency Standards.”
C. Requirements for Lighting Control Systems
Lighting Control Systems are defined by the Standards as requiring two or more components to be installed in the building to provide all of the functionality required to make up a fully functional and compliant lighting control. Lighting control systems may be installed for compliance with lighting control requirements in the Standards providing they meet all of the following requirements:
1. 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 as required in §130.0 through §130.5, §140.6 through §140.8, §141.0, and §150(k).
2. Before a Lighting Control System (including an EMCS) can be recognized for compliance with the lighting control requirements in Part 6 of Title 24, 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 Certificate of Installation.
3. If any of the requirements in the Certificate of Installation fail the installation tests, the Lighting Control System (or EMCS) shall not be recognized for compliance with Title 24.
4. If there are indicator lights that are integral to a lighting control system, they shall consume no more than one watt of power per indicator light.
5. A lighting control system shall meet all of the functional requirements in the Title 20 Appliance Efficiency Regulations for the comparable self-contained lighting control devices
For example, if a lighting control system is installed to comply with the Title 24 requirements for an occupancy sensor, then the lighting control system shall comply with all of the requirements for an occupancy sensor in Title 20. If that same lighting control system is also installed to comply with the Title 24 requirements for a daylighting control, then it shall also comply with all of the requirements for a daylighting control in Title 20. Each of these functions shall be documented in the Certificate of Installation (see item 2 above).
6. If the system is installed to function as a partial-on or partial-off occupant sensor, the installation may be made up of a combination of single or multi-level Occupant, Motion, or Vacancy Sensor Controls, provided that the components installed to comply with manual-on requirements shall not be capable of conversion by the user from manual-on to automatic-on functionality.
D. Requirements for Residential Luminaires
The following requirements apply only to residential luminaires:
1. The requirements for residential luminaires apply to very few nonresidential buildings; only when installed in specifically defined residential function areas that are within a nonresidential building. (See section 5.1.1 C of this chapter)
2. Residential High Efficacy Light Emitting Diode (LED) Lighting. There are no requirements for certifying nonresidential luminaires in accordance with the Title 24 Standards. However, there are some LED luminaires and LED light engines that are designed to be installed in either residential or nonresidential applications. Following are requirements for classifying an LED luminaire as high efficacy for compliance with the residential lighting Standards:
a. To qualify as high efficacy for compliance with the residential lighting Standards in §150.0(k), a residential LED luminaire or LED light engine shall be certified to the Energy Commission according to the requirements in Reference Joint Appendix JA-8. LED lighting that is not certified to the Energy Commission shall be classified as low efficacy for compliance with §150.0(k), regardless of its actual efficacy.
