Notice of Efficiency Committee Workshop

Documents for the Workshop

The California Energy Commission's Efficiency Committee (Chairman Jackalyne Pfannenstiel, presiding member, and Commissioner Art Rosenfeld, associate member) will conduct a workshop to seek comments from interested parties regarding the scope of the next rulemaking to amend the Appliance Efficiency Regulations (Title 20, California Code of Regulations, Section 1601 through Section 1608). The public is invited to attend the workshop, which will be held on:

10:00 a.m.
1516 Ninth Street
First Floor, Hearing Room A
Sacramento, California

(Wheelchair Accessible)

Audio from this meeting will be broadcast over the Internet at:


On December 5, 2007, the Energy Commission approved an Order Instituting Rulemaking (OIR) to amend the Appliance Efficiency Regulations to focus initially on:

  1. "General purpose lighting" in order to help meet the requirements of Assembly Bill 1109 (Huffman and Feuer, Chapter 534, Statutes of 2007);

  2. Battery charging systems;

  3. Updates and clarification; and

  4. Other priority matters as determined by the Committee.[ 1 ]

The OIR says the Committee may divide the rulemaking into phases and establish the scope of each phase appropriately.

The purpose of the Committee scoping workshop is to obtain public input regarding possible changes to Title 20, pursuant to the OIR. The top priority of this rulemaking is to carry out the mandates established in AB 1109 to set new efficiency standards for general purpose lighting by December 31, 2008. The Committee is also seeking input regarding possible new or amended appliance standards (e.g., battery charging systems, other lighting types or appliances) that offer additional significant energy savings, to be considered in the initial rulemaking or subsequent phases.


Assembly Bill 1109

In October 2007, the California Legislature and Governor enacted Assembly Bill 1109 (Huffman and Feuer, Chapter 534, Statutes of 2007), the California Lighting Efficiency and Toxics Reduction Act. Among other things, AB 1109 directed the Energy Commission as follows:

"On or before December 31, 2008, the commission shall adopt minimum energy efficiency standards for all general purpose lights on a schedule specified in the regulations. The regulations, in combination with other programs and activities affecting lighting use in the state, shall be structured to reduce average statewide electrical energy consumption by not less than 50 percent from the 2007 levels for indoor residential lighting and not less than 25 percent from the 2007 levels for indoor commercial and outdoor lighting by 2018."

This appliance standards rulemaking comprises part of the Commission's response to AB 1109. The Commission intends to adopt efficiency standards for lighting in 2008, and may also adopt lighting standards after 2008 in subsequent phases of this rulemaking. The Efficiency Committee also intends to conduct workshops and hearings on other programs and activities that will complement the lighting efficiency standards, in order to meet the aggressive efficiency requirements of AB 1109.

2007 Integrated Energy Policy Report

The Energy Commission's Efficiency Committee and 2007 Integrated Energy Policy Report (IEPR) Committee conducted a joint workshop on June 19, 2007, on opportunities to improve residential lighting efficiency in California.[ 2 ] Efficient light sources, including compact fluorescent lamps, incandescent halogens capsules with infrared coatings, high intensity discharge lamps, and light emitting diodes (LEDs), which offer significant electric energy reductions, are readily available or entering the market.

The 2007 IEPR[ 3 ] found that improving residential lighting in California constitutes a very important opportunity for cost-effective energy efficiency improvement. The greatest opportunity for savings in lighting energy in California lies in addressing the continuing prevalence of incandescent lamps. The majority of sockets in existing houses are still occupied by incandescent lamps, which have an efficacy in the region of 10-17 lumens per watt. When compared with the 45-70 lumens per watt of currently available compact fluorescent lamps, incandescent lamps are clearly very inefficient. The efficacy of incandescent lamps could be increased by 30 percent with technology presently available, such as halogen capsules with infrared coatings. Industry stakeholders suggest that, with additional technological improvements, incandescent efficiency could even exceed 40 lumens per watt. Meanwhile, emerging light emitting diode (LED) sources currently achieve 40 lumens per watt, and could achieve 60 lumens per watt in a few years, and could even reach 100 lumens per watt some time in next decade.

2007 Federal Energy Bill

On December 19, the 2007 Federal Energy Bill was signed including provisions for new federal lighting and appliance efficiency standards. Notably, the Energy Bill includes new standards for general service lamps and provisions for California to have the ability to accelerate the effective date of the federal standards in California. The Committee is interested in comments on how the Federal Energy Bill provisions should affect the scope of new California lighting or other appliance standards to be undertaken in this rulemaking.

The Energy Bill also enacted the Energy Commission standards for external power supplies (Tier 2) as federal appliance standards, and modified the schedule for future federal standards for battery chargers.

Battery Charging Systems

In the process of developing the Energy Commission's current appliance standards for external power supplies, there was a great deal of discussion about the different uses and characteristics of battery charging systems, some of which employ external power supplies. The Commission decided to regulate external power supplies, whether or not they were also part of a battery charging system, and stated the Commission's intent to develop a test method for battery charging systems through the Commission's Public Interest Research Program (PIER). That test method was completed for California by Ecos Consulting and EPRI in September 2007, after four years of PIER- and PG&E-funded research, drafting, stakeholder meetings, public comment, and revision. An associated public comment/response document was completed in December 2007.[ 4 ] Based on this prior work, the Commission recognized in the 2007 IEPR that battery chargers are a candidate for new appliance efficiency standards.

Energy Commission also recognizes federal activities related to battery chargers. The U.S. Environmental Protection Agency adopted ENERGY STAR specifications for both external power supplies and battery charging systems (separately). The test method for battery charging systems used by EPA is older and different than that developed by Ecos Consulting-the EPA method measures standby and maintenance energy use while the Ecos method also includes charging energy use. EPA has already publicly announced its intent to include consideration of charging energy use in the next revision of its battery charger specification.

The U.S. Department of Energy is mandated to develop federal efficiency standards for both external power supplies and battery charging systems, though recent language in the Federal Energy Bill changes the deadlines for both activities.[ 5 ] On December 8, 2006, DOE promulgated a Final Rule adopting the EPA test method for battery charging systems, but indicated they would consider adding charging energy use to their test procedure at a future date. DOE participated actively in the comment and review process leading up to the final draft California battery charger test method. The Energy Commission will be soliciting input from DOE and other stakeholders on any other refinements needed to the final draft California test procedure before adopting it and proceeding with standards consideration based on it. The Energy Commission hopes what is adopted in California will be utilized by DOE and EPA, to include all modes of energy use and ensure consistency for manufacturers and consumers.
