On October 28^th, the US DOE issued new guidance for the industry to comply with the GSL & GSIL certification requirements and timing. In May of 2022, the DOE issued two final rules for these lamps:

1. Expanded definition of GSL & GSIL that became effective on 7/8/22 (“the Definitions Rule”), and
2. The prohibition of selling any GSL below 45 lm/W, effective 7/25/22 (“the Backstop Rule”).

These rules changed which lamps have to be certified to DOE CCMS. Although GSLs must comply with the Backstop Rule, manufacturers are not currently required to certify compliance to the efficacy backstop. This may become required at a future date. DOE is only requiring certification to the applicable pre-backstop standard. See the table below.

DOE will pursue penalties for GSLs that do not meet the 45 lm/W requirement, whether they are certified to a pre-backstop standard or not.

Manufacturers of GSLs must also apply the sampling and test methods of 10 CFR 429.57 for determining represented values and ratings for GSLs, including those subject to the FTC lighting labeling rules, even if they are not currently required to certify compliance to DOE.

There are seven categories of lamps that were not GSILs before the Definitions Rule, but now are GSILs and thus also are GSLs. These are: (1) T shape lamps that use not more than 40 watts or has a length of more than 10 inches; (2) B, BA, CA, F, G16-1/2, G-25, G30, S, or M-14 lamps of 40 watts or less; (3) reflector lamps; (4) rough service lamps; (5) shatter-resistant lamps; (6) 3-way lamps; and (7) vibration service lamps. Each manufacturer/importer must certify that each model of these GSILs complies with the applicable maximum wattage standards. The 45 lm/W backstop sales ban applies to these lamps, as they are now GSLs.

DOE began enforcing the certification requirements for these 7 additional lamp categories on November 1, 2022. Each manufacturer/importer must certify all basic models distributed in commerce in the United States no later than November 1. A manufacturer who begins distributing in commerce any of these additional lamps that were manufactured or imported on or after November 1, 2022, must certify that basic model before distribution. Manufacturers who continue to hold inventory that was manufactured before November 1, 2022 do not need to certify compliance for these basic models. The certification provisions require new basic models of GSILs manufactured or imported on or after November 1, 2022 subject to the energy conservation standards to be certified before distribution in commerce, annually thereafter, and when discontinued.

Rough service and vibration service lamps were subject to a wattage limit before the Definitions Rule, and IRLs were subject to standards. Now each manufacturer/importer of rough and vibration service lamps and IRLs must certify compliance according to the requirements for GSILs.

Existing certification requirements continue to apply to medium base compact fluorescent lamps, candelabra and intermediate base incandescent lamps and lamps defined as GSILs before the Definitions Rule. This requires certifying compliance with the applicable standards, using the applicable sampling plan and certification requirements.

Energy Code Ace has created a summary of California Title 24 code changes for Non-Residential Buildings. The 2022 Title 24, Part 6 Building Energy Efficiency Standards (Energy Code or Title 24, Part 6) updates the 2019 Energy Code.

The 2022 Energy Code is effective as of January 1, 2023. Any projects that apply for a permit on or after this date will be subject to the 2022 Energy Code. Information and documents are available at: https://www.energy.ca.gov/programs-and- topics/programs/building-energy-efficiency-standards/2022- building-energy-efficiency .

Below are the key lighting changes to the Energy Code that apply to nonresidential buildings such as hotels, motels, factories, office buildings, retail spaces and healthcare facilities. In the 2019 Energy Code, high-rise multifamily buildings were grouped with nonresidential buildings. The 2022 Energy Code reorganizes low-rise and high-rise multifamily buildings into one building type and moves requirements for multifamily buildings to their own subchapters.

INDOOR LIGHTING:

Lighting Controls

• 130.1

Mandatory Requirements

Demand-responsive Lighting Controls: There is a new trigger in §110.12(c) based on lighting wattage, not square footage. When general and all other lighting is subject to the multilevel requirements of §130.1(b) for a project 4,000 watts or more, demand-responsive controls are required. A demand-response signal must be capable of automatically reducing general lighting as specified in Table 130.1-A requirements. All other lighting can also be included but is not required.

Manual Area Controls: There are new exceptions to the manual area control accessibility and location requirements.

Shut-OFF Controls: Offices over 250 ft² have new shut-OFF control requirements.

Daylighting Controls: Secondary daylighting controls are now mandatory along with primary and skylit daylighting controls.

Power Adjustment Factors and Lighting Power Allowances
§140.6(a)

Prescriptive Requirements

Since offices over 250 ft² now have Mandatory occupancy sensor control requirements, the large office power adjustment factors (PAFs) have been revised on Table 140.6-C.

The allowed indoor lighting power density has been reduced for many types of buildings and spaces:

• Table 140.6-B: Complete Building Method
• Table 140.6-C: Area Category Method
• Tables 140.6-D, E, F, and G Tailored Methods

Indoor Lighting Alterations

• 141.0(b)2I

Prescriptive Requirements

Changes are made to Table 141.0-F Control Requirments for Indoor Lighting Systems Alterations. Alterations do not need to meet new occupancy sensor requirements for offices 250 ft2 or larger that either:

• Use 80% or less of allowed wattage allowance of §140.6
• Reduce wattage one-for-one over 40%

OUTDOOR LIGHTING:

Outdoor Lighting Zones

Title 24, Part 1 §10-114

Mandatory Requirements

The 2022 Energy Code changes how lighting zones LZ1, LZ2, and LZ3 apply. In Table 8, excerpted from Table 10-114-A, there are two urban zones, and new examples are given. See the excerpt below.

Outdoor Lighting Power Allowances

• 140.7

Prescriptive Requirements

Table 140.7-A General Hardscape Lighting Power Allowance has revised wattage allowances. Asphalt and concrete are no longer differentiated on the table.

An additional allowance for security cameras is added to Table 140.7-B Additional Lighting Power Allowance for Specific Applications. This allowance applies when a security camera is installed within 2 mounting heights of the general hardscape area and mounted over 10 ft away from a building.
