1 Lighting Pagette Update By: Noah Horowitz Sr. Scientist Natural Resources Defense Council November 2005

2 Overview Why a separate group on lighting? (Bulbette rhymes with PAG-ette and baguette!) Quick overview of lighting landscape and key developments in CA and US What the group plans to focus on 2

3 NRDC s Vision of Pagette Not here to micromanage utility programs Ensure: share new ideas/opportunities all key stakeholders in the state are informed of the other s goals and activities we are as effective as possible in gaining short term savings while simultaneously laying the foundation for long term savings 3

4 Ideal Outcome Have overall Lighting Roadmap All components working together in alignment: Utility programs 3 rd party programs PIER research; ET projects Future Codes & standards (Title 20, 24) M&V market assessment, field studies California Lighting Technology Center With national efforts CEE, ENERGY STAR, PNNL, LRC, etc. 4

5 Residential Snapshot Per recent CA study by RLW Analytics (2005) 23 fixtures and 41 lamps per home 11% of fixtures have 1 or more CFLs (up from just 1% in 2000) 57% of all homes have 1 or more CFLs (up from 12% in 2000) Moving from get them to try the new and improved bulbs to keep coming back for more (replace current ones and put them in other sockets) 5

6 Why Lighting? Lighting represents a large slice of statewide electricity use 15% residential 30% commercial Biggest part of IOU program budgets and projected kwh savings are lighting related 6

7 Observation Focus has been: a) Tactical - What are we going to deliver this year and next? Should the rebate be $2 or $3 per CFL? b) Strategic - What are we trying to accomplish/where do we want to be? (And then, how do we get there? vs. We need to do both. 7

8 Scope Focus on residential and small commercial for now. (Include hotels, dorms, multifamily, restaurants, etc.) Retrofit and new construction. Form large commercial group if sufficient interest (recognize different fixture types and applications, players including ESCOs, developers, maintenance staff, etc.) 8

9 Screw-Based CFL Quality Due in large part to the third-party off-theshelf testing program, called PEARL, ENERGY STAR-labeled CFL quality improving: Bare bulb doing very well Poor performance seen by covered lamps (globes, covered A-lamps and reflectors) DOE about to delist roughly half of all listed reflector models 9

10 100% Percentage of Compliance with Energy Star Spec for All "Bare Bulb" CFLs tested in PEARL* (Categorized by Cycles) Percentage 90% 80% 70% 60% 50% 40% 30% 20% 10% Cycle1 Cycle2 Cycle3 Cycle4 Cycle5 Cycle6 0% % Passed % Passed % Passed % Passed Efficacy (lm/w) 1000-hour Lumen Maintenance Parameters 40%-life Lumen Maintenance Rapid Cycle Stress Test * 40%-life Lumen Maintenance does not include all Cycle 6 CFLs yet 10

11 100% 90% Percentage of Compliance with Energy Star Spec for All CFLs tested in PEARL* (Categorized by CFL bulb type) 80% Percentage 70% 60% 50% 40% 30% Bare lamp Covered lamp Reflector lamp 20% 10% 0% % Passed % Passed % Passed % Passed Efficacy (lm/w) 1000-hour Lumen Maintenance 40%-life Lumen Maintenance Parameters Rapid Cycle Stress Test * 40%-life Lumen Maintenance does not include Cycle 6 CFLs yet 11

12 More on PEARL CA utilities have provided generous financial support for PEARL Moving to sustainable model for testing Funded by industry Pay to play hardwired into ENERGY STAR partner agreement 12

13 Recent Developments - CFLs ENERGY STAR CFLs Specification currently being revised New specification will likely include: Third party off the shelf testing a la PEARL funded by industry Tighter efficacy levels for bare bulbs Faster run-up time (1 minute instead of 3) In-situ test reqt. for reflector lamps Mercury limit (not in current draft) 13

14 Recent Code Changes I A. Code changes Title 24 (effective 10/05) Increases demand for efficient kitchen fixtures, in particular air-tight recessed cans Lots of controls (manual on/auto off) and dimmers will be installed E-Star porch lights E-Star fixtures (bathroom, bedroom, etc.) will be used by some builders 14

15 Recent Code Changes II B. Title 20 Code Change Torchiere limit (190W) Efficacy standards for various screw-based lamp types Incandescent standards (two tiers) C. Federal Energy Bill All CFLs must meet key elements of 2001 ENERGY STAR specification (Illegal to sell non-complying models beginning in 2006!) Ceiling Fans must include ES screw-based CFLs, or be an ES fixture, or may not exceed X W total 15

16 Incandescent Standard I CEC to establish two-tiered efficacy standard for general service lamps (the incandescent ) Roughly 100 million incandescent sold/yr in CA. Small per bulb savings x lots of bulbs = BIG kwh/yr and MW savings Tier 2 proposal: 3-5 W savings per lamp >400 GWh/yr savings Effective around 1/1/08 (might slip) 16

17 Incandescent Standard II What role should utilities play to prepare the market for the standard? Communication/marketing challenges: Super-efficient incandescent vs. CFL? Don t want consumers to abandon CFLs for slightly better incandescent 15 W CFL still much better than 53 W incandescent 17

18 Recent Developments - Fixtures ENERGY STAR Fixtures Bans magnetic ballasts, except for HID outdoor Beginning to promote easily removable ballasts Moving industry to a single ballast/fixture base assembly Will allow self-ballasted pin-based lamps in October. 18

19 GU24 Socket Background Goal: a standard line-voltage socket (the base of the pop out ballast where it connects to the 120V supply) Why: To address a barrier to ballast interchangeability and consumer adoption of energy-efficient products As the market penetration of replaceable electronic ballasts for ENERGY STAR residential lighting fixtures increase, a standard line-voltage socket and a standard pin base on the replaceable ballasts becomes necessary GU24 socket 3-D rendition

20 Self Ballasted Lamp Similar to a screw-base compact fluorescent, but rather than using a screw base the ballast connects to the GU24 socket with pins. Easy, one unit replacement when either the lamp or ballast fails eliminates consumer pin confusion when purchasing replacement lamps. Because ballast and lamp are integral the overall length is shorter allowing better fit in variety of luminaires. Standardized for interchangeability between manufactures. Lower cost than two-piece lamp and ballast. GU24 Socket Ballast

21 BIG PICTURE Need higher level roadmap to make sure: Achieve savings targets for 2006, 2007, etc. AND Doing the things necessary to pull next generation of products to market Test methods Benchmarking Pilots Bulk procurement Incentives New standards (Title 20, 24) 21

22 Near Term I 1) Mercury: Be part of dialogue and solution for: Minimize mercury content of CFLs (help achieve consensus test method) Be part of dialogue and solution for building lamp collection and recycling systems. 22

23 Near Term II 2) Replacement Ballasts and Lamps Continue to encourage easily replaceable plug and play ballasts (like changing a AA battery) in new fixtures Ensure retail availability of replacement ballasts and lamps (expect increased demand due to Title 24-driven demand) Develop strategy around GU-24 (universal pin-based socket and connector) 23

24 Near Term III 3) Solid State Lighting ( LED s ) Coming on fast Need to support development of appropriate metrics and test methods Initial applications expected for things like refrigerator case lighting, elevators, etc. Challenges: is it a lamp, a fixture, etc.? 24

25 Near Term IV 4) Holiday LED Lighting Good vehicle for high profile Christmas tree lighting (state tree, city hall) events Opportunity to link with themes of save energy, money and help protect the environment year-round => BUY ENERGY STAR Could bundle buy 2 sets of LED holiday lights get $ off qualified E-STAR lighting products 25

26 Near Term V 5) Continue to push for ongoing CFL and fixture quality Participate in PEARL Cycle 7 Track and provide input on successor testing program by DOE (CFLs) and EPA (fixtures) Make ENERGY STAR know you depend on consumers having a good experience with these products and are banking on them lasting and provided the projected savings. 26

27 Near Term VI 6) Focus on key segments of CFL market: Dimmable 3-way High wattage (100 W and above) products 27

28 Near Term VII 7) Data Collection: Time to gather up-to-date time of use data for residential lighting. Need comprehensive study that includes metering. Continue in-home studies like RLW fixture and bulb type count. 28

29 Near Term VIII- The better incandescent Hold statewide strategy meeting Reach out to other leading states NEEA, NEEP, NY, etc. to have them join in potential regional bulk procurement/upstream rebates and similar standards 29

30 Next Steps Follow-up meeting in December: Bring experts from Energy Star Discuss mercury in greater depth Engage industry as appropriate Discuss CA priorities evaluation, research at CLTC, etc. Begin to draft overall strategy piece Convene commercial building group? 30
