Measures updated

1. Residential CFLs 2. Residential showerheads

5/3/2011

Residential CFLs

Based savings on study by KEMA of 2006-08 California programs Different room types than current measures Lower overall hours of operation (2.3 -> 1.9

average hours/day) Lower baseline watts per bulb (71 -> 61 W

average) for 2011 results in lower delta watts per bulb (52 -> 44 W average)

5/3/2011

Residential CFLs

Converted retail measures into one overall average measure Eliminated by-room measures – information not

available Eliminated “Complete dwelling unit”

measure

(These recommendations were not noted previously)

2013 Baseline Watts

Residential CFLs

Accounted for Energy Independence and Security Act (EISA) by adjusting the baseline for 2012 and 2013 Proposing single set of measures through 2013,

using an average baseline for 2011, 2012, 2013 For the 2012 period, incandescent baseline is

adjusted by replacing 85W – 150W with 72W (intended EISA replacement)

Bulbs in this 100W range account for 12% of baseline For the 2013 period, baseline is adjusted by

replacing 70W – 84W with 53W (intended EISA replacement)

Bulbs in this 75W range account for 11% of the baseline5/3/2011

Philips Celebrates Earth Day with Launch of EcoVantage Bulbs, Incandescents that are 28 Percent More Energy-efficient

DiversityAndCommerce

Available at the Home Depot, EcoVantage is a

dimmable, mercury-free option that meets

upcoming energy requirements, while offering

same shape & light quaility as the traditional

Edison bulb.

SOMERSET, N.J. /PRNewswire/ -- In celebration

of Earth Day, Philips Lighting is announcing the

availability of the Philips EcoVantage range of light bulbs exclusively at The Home Depot, an energy-efficient

incandescent that is a more sustainable alternative to traditional bulbs. Because EcoVantage uses halogen

technology, it offers the same aesthetically pleasing light quality and dimmability as a traditional

incandescent, but with energy savings of at least 28 percent(1).

Impact on Baseline Wattage of changes

Current201120122013AverageWatts

Account for CFLs in the baseline for retail measure?

Some CFLs are purchased to replace CFLs However, a burned out CFL could still be

replaced with an incandescent The average CFL lifespan is 6 years vs.

0.92 years for incandescents Would need research to really know how

many CFL purchases are CFL replacements compared with “first-time” purchases

Recommendations

Leave CFLs out of the baseline

Proposed RTF Motion:

“I_______ move the RTF Approve the residential compact fluorescent lighting measure for unit energy savings based on the proposed EISA phase in baseline wattage, adjusted hours of operation, and a sunset date of December 31, 2013.”

5/3/2011

Residential low-flow showerheads

Did NOT add direct-install multi-family category Fewer occupants per residence AND fewer showers per residence leads

to similar showers per day per primary shower Collapsed retail measures into single measure

Eliminated primary vs. secondary shower distinction and electric vs. gas sub-measures

(This was not noted as a recommendation earlier) Changed low-flow shower length to be the same as baseline

Previous assumption was that low-flow showers were longer in duration Review of studies does not support that conclusion

Changed mail-by-request install rate from 60% to 76% Average of earlier reported values of 93% (SCL), 59% (ETO), and 76%

(2008 PSE survey of installation rates)
