# CHAPTER 12. LIFE-CYCLE COST SUB-GROUP ANALYSIS

1 2.1 INTRODUCTION

Chapter 8 describes the Life-Cycle Cost (LCC) and Payback Period (PBP) analysis that

e xamines impacts of energy conservation standards on the U.S. population. In analyzing the

potential impact of new or amended standards on consumers, DOE further evaluates the impact

on identifiable groups of consumers (i.e., subgroups) that may be disproportionately affected by

a national standard level. The LCC subgroup analysis evaluates impacts by analyzing the LCC

and PBPs for subgroups of households or commercial and industrial consumers. For general

service fluorescent lamps (GSFL) and incandescent reflector lamps (IRL), DOE identified four

consumer subgroups that warranted further study: low-income consumers, houses of worship,

institutions that serve low-income populations, and consumers of T12 electronic ballasts. The

analysis determines whether these groups of consumers would be adversely affected by any of

the trial standard levels.

DOE determined the impact on consumer subgroups for GSFL and IRL using the LCC

Spreadsheet Model, which allows for the examination of particular consumer subgroups. The

LCC analysis for the general population (described in Chapter 8) focuses on consumers that use

GSFL and IRL. DOE has the ability to use the LCC Spreadsheet Model to analyze the LCC for

any subgroup by sampling only the data that apply to that subgroup. (Chapter 8 explains in detail

the inputs to the model used in determining LCC and PBPs.)

This chapter describes the subgroup identification in further detail and gives the results of

the LCC and PBP analyses for both GSFL and IRL. Section 12.2 discusses the definitions and

inputs used for each of the four subgroups while section 12.3 gives the LCC and PBP results for

the four subgroups.

12.2 SUB-GROUP DEFINITIONS AND INPUTS TO THE SUB-GROUP ANALYSIS

DOE researched the subgroups by utilizing the 2001 RECS i 

# and 2003 CBECS ii 

# databases

a s well as the 2002 U.S. Lighting Market Characterization (LMC) iii 

# . DOE also used financial

s ources as described below. To explore institutions that serve low-income populations, DOE

assessed a variety of small and large non-profit, for-profit, and governmental institutions.

# d efined low-income consumers as residential consumers with incomes at or below the poverty

line as defined by the U.S. Census Bureau. DOE defines low-income consumers in the same

way for this rule. The poverty line varies with household size, head of household age, and family

income. Table 12.2.1 summarizes the criteria given for selecting low-income households from

the 2001 RECS database.

# 1 2-2



# T able 12.2.1 2001 RECS Definition of Low-Income Households

Household Size Owner Age Family Income

1 65 and over less than $7,525

1 64 and under less than $8,163

2 65 and over less than $9,491

2 64 and under less than $10,507

3 Any less than $12,516

4 Any less than $16,036

5 Any less than $18,952

6 Any less than $21,389

7 Any less than $24,268

8 Any less than $27,091

9 or more Any less than $31,971

DOE discovered that residential low-income consumers faced electricity prices that were

lower by 0.1 cents per kWh than the prices faced by consumers above the poverty line in 2001,

as shown in Table 12.2.2. The weights in the table represent approximately the number of

households represented by the statistic. Using this information, DOE multiplied the U.S. average

residential electricity price of $0.112 (2007$) by 0.096/0.097 (approximately 0.9897) to arrive at

the low-income residential electricity price of approximately $0.111. DOE then used this price

as a modification to the residential sector primary LCC analysis. Because of the large diversity

of low-income families in the residential sector, DOE does not expect to see differences in other

inputs like operating hours, lamp types, or event response behaviors that vary significantly on

average from the residential sector as a whole. Therefore, with the exception of electricity prices,

DOE used the same inputs in the low-income consumer subgroup analysis as it used for the

general residential sector population.

12.2.2 Institutions of Religious Worship

DOE found that institutions of religious worship operate for fewer hours per year than

any other building type in the commercial sector according to the 2003 CBECS and LMC. The

LMC indicates the occurrence of certain room types within a given building type and the

operating hour characteristics of GSFL and IRL in these rooms. The 2003 CBECS data indicates

# 1 2-3



# the probability a certain commercial building type exists in the nation. As discussed in Chapter

6 , an analysis using the 2003 CBECS data and LMC shows that GSFL operate on average for

3,435 hours per year in the commercial sector while IRL operate on average for 3,450 hours per

year in the commercial sector. According to the LMC, institutions of religious worship operate

GSFL for 1,705 operating hours per year and IRL for 1,609 operating hours per year. As the

operating hours for these institutions is significantly different than the operating hours for the

typical commercial consumer, DOE modified the commercial sector primary LCC analysis by

changing the operating hours. In general, because of the large diversity of institutions of

religious worship in the commercial sector, DOE does not expect to see differences in other

inputs like electricity prices, or sales tax that vary significantly on average from the commercial

sector as a whole. Therefore, with the exception of operating hours, DOE used the same inputs in

the institutions of religious worship subgroup analysis as it used for the general commercial

sector population.

12.2.3 Institutions That Serve Low-Income Populations

DOE also performed research on institutions that serve low-income populations and

found a wide variety of non-profit, for-profit, and governmental organizations. Because of the

large diversity of organizations in this sector, DOE does not expect to see operating hours, lamp

types, or event response behaviors that vary significantly on average from the commercial sector

as a whole. DOE, however, expects that the majority of organizations serving low-income

populations are small non-profit groups. For this reason, DOE chose a subgroup scenario with a

discount rate that is 3.8 percent higher than the average discount rate for the commercial sector

(for a discount rate of 10.8 percent), based on the development of the discount rate for small

business subgroups in the Cooking Products and Commercial Clothes Washers NOPR analysis, vii



# a s described below.

The Small Business Administration (SBA) defines a small business by its annual receipts

or its number of employees. Although the methodology is appropriate, the capital asset pricing

model (CAPM) used in Chapter 8 for the general population underestimates the cost of capital

for small companies. In CAPM, the risk premium β is used to account for the higher returns

associated with greater risk. However, for small companies, particularly very small companies,

historic returns have been significantly higher than the CAPM equation predicts. This additional

return can be accounted for by adding a size premium to the cost of equity for small firms:

# +×+= β

D OE obtained size premium data from Ibbotson Associates’ Stocks, Bonds, Bills, and

In flation 2007 Yearbook



# . viii 

# For the period of 1926–2006, the average size premium for the

s mallest companies in all industries is 6.27 percent, implying that on average, historic

# 1 2-4



# performance of small companies has been 6.27 percent higher than the CAPM estimate of the

s mall company cost of equity. 1



# To estimate the difference in discount rate between small companies and the industry

average, DOE calculated the average discount rate for small companies in the entire U.S. market

(all industries) and also for all companies in the U.S. market. DOE calculated the real weighted

average cost of capital as described in Chapter 8, using the cost of equity including a size

premium for small companies instead of the CAPM cost of equity. Discount rate estimates are

presented below in Table 12.2.3 for the entire market based on data from Damodaran. 2, ix

In Chapter 8, DOE estimated the average discount rate for the commercial sector to be

7.0 percent. Applying the additional small capitalization (small cap) discount rate premium of

3.8 percent presented in Table 12.2.3, the discount rate for small companies is approximately

10.8 percent. Because DOE expects that the majority of institutions serving low income

populations are small companies, DOE is using the discount rate of 10.8 percent for the LCC

subgroup analysis of institutions serving low income populations, as a modification to the

commercial sector primary LCC analysis.

12.2.4 Consumers of T12 Electronic Ballasts

DOE analyzed consumers of T12 electronic ballasts as a consumer subgroup because

consumers that already have a T12 electronic system would be more adversely impacted than

those consumers with magnetic systems particularly when a standard forces a consumer to

replace their lamp-and-ballast system. For this subgroup, DOE only analyzed the events where a

consumer purchases a T12 lamp in the baseline and a new T8 lamp and ballast system in the case

of a standard. This event is only relevant at EL4 and EL5, as T12 lamps are no longer available

at these standard levels. In the commercial and industrial sectors, DOE analyzed consumers who

undergo Event II, the standards-induced retrofit event, where the commercial sector consumer

proactively replaces their functioning T12 lamp-and-ballast system with a T8 lamp-and-ballast

system in anticipation of not being able to purchase a new T12 lamp in the event of a T12 lamp

failure. In the residential sector, DOE analyzed consumers who undergo Event IB, the lamp

failure event, where consumers faced with a T12 lamp failure replace their entire functioning

system with a T8 system. Because the T12 electronic system is more efficacious than T12

magnetic systems, consumers with electronic systems experience lower operating cost savings

than those consumers with magnetic systems. In order to analyze the affect on consumers of T12

# 1 2-5



# electronic systems, DOE established a new baseline electronic T12 system and modified

s tandards case systems so that both light output is maintained in the case of a standard and

energy is saved. These systems are identified in Appendix 5A. All other factors of the LCC

subgroup analysis remain the same as in the primary analysis.

12.3 LCC SUB-GROUP RESULTS

The following tables present the results of the LCC subgroup analyses for low-income

consumers, institutions of religious worship, and institutions that serve low-income populations.

The subgroup analyses is based on the primary LCC analysis described in Chapter 8 of the TSD,

with modifications described above in section 12.2 of this appendix.

12.3.1 Low-Income Consumers

The results for the LCC and PBP subgroup analyses for low-income consumers are

shown in Table 12.3.1 and Table 12.3.2 for GSFL and in Table 12.3.5 through Table 12.3.7 for

IRL. Table 12.3.3 and Table 12.3.4 show a summary of the GSFL results. For information on

the acronyms used in the summary tables refer to Chapter 8. LCC results that were positive in

the primary LCC analysis remained positive for this subgroup; the same occurred for negative

primary LCC results. In general, for GSFL and IRL, LCC savings are several cents lower for

low-income residential consumers than they are for the rest of the residential sector due to the

lower electricity prices faced by low-income residential consumers. This also causes the

# 12.3.2 I nstitutions of Religious Worship

DOE researched institutions of religious worship and discovered that these institutions

had the lowest operating hours of any non-mall commercial building. Specifically, these were

1,705 hours per year for GSFL (vs. the commercial sector average of 3,435 hours per year) and

1,609 hours per year for IRL (vs. the commercial sector average of 3,450 hours per year). The

LCC subgroup analysis for institutions of religious worship is identical to the main commercial

sector LCC analysis except for lower operating hours, resulting in an analysis period of 11 years

for 4-foot GSFL, 8 years for 8-foot GSFL, and 1.9 years for IRL. Institutions of religious

worship experience lower LCC savings than the rest of the commercial sector, particularly for

GSFL standards-induced retrofit events. This is because the longer analysis period causes

operating cost savings to be discounted more heavily than in the primary commercial LCC

analysis (as the systems last for more years).

12.3.2.1 Product class: 4-foot MBP ≤4,500K

LCC and PBP results for 4-foot MBP systems with color correlated temperature (CCT)

less than 4,500K in institutions of religious worship are shown in Table 12.3.8 through Table

12.3.10. In Event IB (Lamp & Ballast Replacement) and Event II across the 40W and 34W T12

baseline lamps, institutions of religious worship typically experience LCC savings that are up to

approximately 20 dollars lower than the rest of the commercial sector. Payback periods are

almost a decade longer in some cases. In Event IA (Lamp Replacement) and Event III (as well

as Event V for the 32W T8 baseline), institutions of religious worship experience LCC savings

that are up to approximately 7 dollars lower than the rest of the commercial sector. Payback

periods for Event III in institutions of religious worship are several decades longer than in the

primary commercial sector analysis, however. For the 32W T8 baseline, LCC savings in

institutions of religious worship are up to approximately 6 dollars lower than in the primary

commercial sector analysis for all events.

For all three baselines, LCC savings that are positive in the primary commercial sector

analysis generally remain positive for institutions of religious worship. This is not always the

case, however. For example, the 40W T12 MBP system in institutions of religious worship,

Event IB (Lamp & Ballast Replacement) LCC savings are negative for EL3, in contrast to the

positive LCC results in the primary commercial sector analysis. Similarly, Event II LCC savings

for the 40W T12 baseline in institutions of religious worship are negative for EL3 as well as the

30W T8 system option at EL4.

For the 34W T12 baseline, LCC savings in Event IB that are positive in the primary

commercial sector analysis remain positive except for the 32W T8 replacement system option at

EL2. LCC savings for Event II for the 34W T12 baseline lamp remain positive except for the

32W and 30W replacement T8 systems at EL4 and EL5. LCC savings for the 32W T8 baseline

remain positive for institutions of religious worship. Table 12.3.11 shows summary results for

all three 4-foot MBP baselines.12-14Table 12.3.8 LCC and PBP Results for a Three-Lamp 4-Foot 40W T12 MBP System Operating in Institutions of ReligiousWorshipEventResponseEfficacy LevelRatedLampEfficacyDesign OptionLCCLCC SavingsInstalledPriceOperatingCostSavings(StartYear)PaybackPeriod% MeanLumensfromBaselinelms/W$$$$yrs%BaselineBaseline78.041 W T12 & 0.95 BF Mag171.210.0013.960.00N/A0.0A: LampReplacementEL391.234 W T12 & 0.88 BF Mag154.7816.4325.133.523.2-10.3EL180.541 W T12 & 0.88 BF Elec188.59-17.3872.513.5816.4-3.5EL182.941 W T12 & 0.87 BF Elec190.32-19.1177.163.6917.1-2.7EL286.232.5 W T8 & 1.18 BF Elec187.73-16.5265.112.6219.58.7EL287.841 W T12 & 0.87 BF Elec190.59-19.3877.453.6917.23.3EL391.234 W T12 & 0.88 BF Elec171.62-0.4177.066.2510.1-10.3EL390.832.5 W T8 & 1 BF Elec171.49-0.2868.215.2910.3-1.0EL492.332.5 W T8 & 0.88 BF Elec152.2618.9560.967.076.6-8.3EL493.830.4 W T8 & 1 BF Elec164.147.0769.496.488.6-2.0EL493.026.6 W T8 & 1.18 BF Elec161.429.7973.256.918.61.4EL595.432.5 W T8 & 0.88 BF Elec153.7017.5162.527.076.9-6.2Event I: LampFailureB: Lamp &BallastReplacementEL596.028.4 W T8 & 1 BF Elec157.9513.2668.897.547.3-6.4BaselineBaseline78.041 W T12 & 0.95 BF Mag163.600.0013.960.00N/A0.0EL180.541 W T12 & 0.88 BF Elec190.22-26.6274.823.5817.0-3.5EL182.941 W T12 & 0.87 BF Elec191.95-28.3579.463.6917.8-2.7EL286.232.5 W T8 & 1.18 BF Elec189.36-25.7667.422.6220.48.7EL287.841 W T12 & 0.87 BF Elec192.22-28.6279.763.6917.83.3EL391.234 W T12 & 0.88 BF Elec173.25-9.6579.376.2510.5-10.3EL390.832.5 W T8 & 1 BF Elec173.12-9.5270.525.2910.7-1.0EL492.332.5 W T8 & 0.88 BF Elec153.899.7163.267.077.0-8.3EL493.830.4 W T8 & 1 BF Elec165.77-2.1771.806.488.9-2.0EL493.026.6 W T8 & 1.18 BF Elec163.050.5575.566.918.91.4EL595.432.5 W T8 & 0.88 BF Elec155.338.2764.837.077.2-6.2Event II:StandardsInduced RetrofitLamp & BallastReplacementEL596.028.4 W T8 & 1 BF Elec159.584.0271.197.547.6-6.412-15Table 12.3.8 LCC and PBP Results for a Three-Lamp 4-Foot 40W T12 MBP System Operating in Institutions of ReligiousWorship (continued)EventResponseEfficacy LevelRatedLampEfficacyDesign OptionLCCLCC SavingsInstalledPriceOperatingCostSavings(StartYear)PaybackPeriod% MeanLumensfromBaselinelms/W$$$$yrs%BaselineBaseline78.041 W T12 & 0.88 BF Elec181.980.0065.890.00N/A-7.4*EL180.541 W T12 & 0.87 BF Elec187.77-5.7972.510.1158.2-4.6EL182.941 W T12 & 0.87 BF Elec190.32-8.3477.160.1199.0-2.7EL287.841 W T12 & 0.87 BF Elec190.59-8.6277.450.11101.63.3EL391.234 W T12 & 0.88 BF Elec171.6210.3577.062.684.2-10.3EL390.832.5 W T8 & 1 BF Elec171.4910.4968.211.721.3-1.0EL492.332.5 W T8 & 0.88 BF Elec152.2629.7160.963.500.0-8.3EL493.830.4 W T8 & 1 BF Elec164.1417.8469.492.911.2-2.0EL493.026.6 W T8 & 1.18 BF Elec161.4220.5573.253.332.21.4EL595.432.5 W T8 & 0.88 BF Elec153.7028.2762.523.500.0-6.2Event III:Ballast FailureLamp & BallastReplacementEL596.028.4 W T8 & 1 BF Elec157.9524.0368.893.960.8-6.4BaselineBaseline/EL286.232.5 W T8 & 1.18 BF Elec189.360.0067.420.00N/A8.7EL391.234 W T12 & 0.88 BF Elec173.2516.1179.373.633.3-10.3EL390.832.5 W T8 & 1 BF Elec173.1216.2470.522.671.2-1.0EL492.332.5 W T8 & 0.88 BF Elec153.8935.4763.264.450.0-8.3EL493.830.4 W T8 & 1 BF Elec165.7723.5971.803.861.1-2.0EL493.026.6 W T8 & 1.18 BF Elec163.0526.3175.564.281.91.4EL595.432.5 W T8 & 0.88 BF Elec155.3334.0364.834.450.0-6.2Event IV:Ballast RetrofitLamp & BallastReplacementEL596.028.4 W T8 & 1 BF Elec159.5829.7871.194.910.8-6.4* Comparative lumens are sometimes non-zero for baseline T12 electronic systems under Event Type 3 and 4 (ballast failure and retrofit) because the lumen package is compared to a system with a T12magnetic ballast.

Table 12.3.12 presents the results for an electronically ballasted 4-foot T5 miniature bipin

(MiniBP) standard output (SO) baseline system operating in institutions of religious worship.

LCC savings are all positive for this baseline lamp and subgroup, as in the primary commercial

sector LCC analysis. For Event I, institutions of religious worship face LCC savings that are

almost 2 dollars lower than the rest of the commercial sector, with a payback period

approximately 4 years longer. For Events III and V, LCC savings are approximately 5 dollars

lower for institutions of religious worship. Payback periods are approximately 1.5 years higher

for Event III, while payback periods remain immediate for Event V. Table 12.3.13 shows a

Table 12.3.14 through Table 12.3.16 present the results for the 75W T12, 60W T12, and

59W T8 8-foot single pin (SP) slimline baseline systems operating in institutions of religious

worship. LCC savings that are positive in the primary commercial sector analysis remain

positive for these baselines and this subgroup except for the EL5 system in Event II for the 75W

T12 baseline. LCC savings in institutions of religious worship are reduced by approximately 15

dollars for Events IB and II for the 75W and 60W T12 baselines; payback periods for these

events and baselines are increased by a decade for most system options. For EL3 in Event II for

the 75W and 60W T12 baselines, payback periods are increased by approximately 30 years. For

Events IA, III, IV, and V for all applicable baselines, LCC savings are reduced by up to

approximately 5 dollars in institutions of religious worship. Payback periods are increased by

several years. Table 12.3.17 shows a summary of the LCC and PBP results for 8-foot SP

# 12.3.2.4 I ncandescent reflector lamps

Table 12.3.18 through Table 12.3.20 present the results for the 90W PAR38, 75W

PAR38, and 50W PAR30 incandescent reflector lamps operating in institutions of religious

worship. The analysis period is 1.9 years. LCC savings that are positive in the primary

commercial sector analysis remain positive for this subgroup. LCC savings are reduced by

several cents to approximately 2 dollars in most cases, and payback periods are increased by

approximately 1 year. For EL1 in the 90W and 75W PAR38 baselines, however, LCC savings

are increased for institutions of religious worship. This is because in the primary commercial

sector analysis, the lamp at EL1 is purchased twice in the first analysis year. In the analysis for

institutions of religious worship, however, the lamp at EL1 is purchased once in the first year and

once in the second year. Because discounting lowers the present value of the lamp purchase cost

in the second year, LCC savings are increased for this subgroup at EL1.12-28Table 12.3.18 LCC and PBP Results for a 90W PAR38 Lamp Operating in Institutions of Religious WorshipEventResponseEfficacy LevelLampEfficacyLamp OptionLCCLCC SavingsInstalledPriceOperatingCostSavings(StartYear)PaybackPeriod% InitialLumensfromBaselinelms/W$$$$yrs%BaselineBaseline14.690W, 14.6lm/W & 2500hrs,Halogen31.820.006.200.00N/A0.0EL115.385.7W, 15.3lm/W &2500hrs, Improved Halogen(Xenon)31.810.007.140.681.40.0EL215.982.5W, 15.9lm/W &6000hrs, Long Life HIR26.675.147.761.191.30.0EL216.679W, 16.6lm/W & 3000hrs,Improved Halogen (Silver)28.852.977.581.740.80.0EL318.070W, 18lm/W & 3000hrs,HIR26.605.217.763.160.5-3.8EL419.866W, 19.8lm/W & 4000hrs,Improved HIR24.946.879.083.790.80.0Event I: LampFailure; or EventV: NewConstruction andRenovationLampReplacement orNew LampPurchaseEL521.060W, 21lm/W & 4200hrs,Improved HIR Plus23.538.289.654.740.7-3.812-29Table 12.3.19 LCC and PBP Results for a 75W PAR38 Lamp Operating in Institutions of Religious WorshipEventResponseEfficacy LevelLampEfficacyLamp OptionLCCLCC SavingsInstalledPriceOperatingCostSavings(StartYear)PaybackPeriod% InitialLumensfromBaselinelms/W$$$$yrs%BaselineBaseline14.075W, 14lm/W & 2500hrs,Halogen27.780.006.200.00N/A0.0EL114.671.7W, 14.6lm/W &2500hrs, Improved Halogen(Xenon)28.04-0.267.140.521.80.0EL215.368.8W, 15.3lm/W &6000hrs, Long Life HIR22.984.797.760.981.60.0EL215.966W, 15.9lm/W & 3000hrs,Improved Halogen (Silver)25.352.437.581.421.00.0EL317.560W, 17.5lm/W & 3000hrs,HIR23.913.877.762.370.70.0EL419.155W, 19.1lm/W & 4000hrs,Improved HIR21.985.809.083.160.90.0Event I: LampFailure; or EventV: NewConstruction andRenovationLampReplacement orNew LampPurchaseEL520.351.7W, 20.3lm/W &4200hrs, Improved HIR Plus21.306.489.653.680.90.012-30Table 12.3.20 LCC and PBP Results for a 50W PAR30 Lamp Operating in Institutions of Religious WorshipEventResponseEfficacy LevelLampEfficacyLamp OptionLCCLCC SavingsInstalledPriceOperatingCostSavings(StartYear)PaybackPeriod% InitialLumensfromBaselinelms/W$$$$yrs%BaselineBaseline12.650W, 12.6lm/W & 3000hrs,Halogen19.050.005.590.00N/A0.0EL113.247.8W, 13.2lm/W &3000hrs, Improved Halogen(Xenon)19.39-0.356.530.352.70.0EL213.546W, 13.5lm/W & 6000hrs,Long Life HIR16.502.557.150.632.5-1.6EL214.045W, 14lm/W & 3000hrs,Improved Halogen (Silver)19.09-0.046.980.791.80.0EL315.141.8W, 15.1lm/W &3000hrs, HIR18.410.647.151.301.20.0EL417.040W, 17lm/W & 4000hrs,Improved HIR17.461.588.471.581.87.9Event I: LampFailure; or EventV: NewConstruction andRenovationLampReplacement orNew LampPurchaseEL519.140W, 19.1lm/W & 4200hrs,Improved HIR Plus17.681.379.041.582.221.4

# 12.3.3 I nstitutions That Serve Low-Income Populations

DOE assumed that the majority of institutions that serve low-income populations are

small non-profit organizations; thus, DOE used a higher discount rate of 10.8% (vs. the 7.0%

discount rate for the primary commercial sector analysis). All other factors of the LCC subgroup

analysis remained the same as in the primary commercial sector analysis. As a result of the

higher discount rate, institutions that serve low-income populations experience lower LCC

savings than the rest of the commercial sector. For Events I and III for all analyzed GSFL

product classes, savings are several dollars lower than for the rest of the commercial sector. For

Event II for GSFL, LCC savings can be up to approximately 15 dollars lower than for the rest of

the commercial sector. For IRL, LCC savings are several cents lower than for the rest of the

commercial sector. Although LCC savings are lower, positive primary LCC results remained

positive for this subgroup while negative primary LCC results remained negative for this

subgroup. The payback periods for this subgroup are identical to the payback periods in the

commercial sector LCC analysis because DOE computes simple PBPs, which do not take into

account discounting; thus, changes in discount rates do not change the PBPs.

12.3.3.1 Product class: 4-foot MBP ≤4,500K

LCC and PBP results for 4-foot MBP systems with CCT less than 4,500K in institutions

that serve low income populations are shown in Table 12.3.21 through Table 12.3.23. In

comparison with the primary commercial sector analysis, LCC savings for institutions that serve

low income populations are reduced by up to approximately 10 dollars. For Events III and IV in

the 40W and 34W T12 baselines as well as all events in the 32W T8 baseline, reductions in LCC

savings are approximately 3 dollars.

For all three baselines, LCC savings that are positive in the primary commercial sector

analysis generally remain positive for institutions that serve low income populations. This is not

always the case, however. For example, both of the EL3 system options for Event II in the 40W

T12 baseline have negative LCC savings for this subgroup. In the 34W T12 baseline, the 32W

T8 design option at EL2 for Event IB and the 32W T8 design option at EL3 in Event II also have

negative LCC savings. Table 12.3.24 shows summary results for all three 4-foot MBP baselines.12-32Table 12.3.21 LCC and PBP Results for a Three-Lamp 4-Foot 40W T12 MBP System Operating in Institutions That ServeLow-Income PopulationsEventResponseEfficacy LevelRatedLampEfficacyDesign OptionLCCLCC SavingsInstalledPriceOperatingCostSavings(StartYear)PaybackPeriod% MeanLumensfromBaselinelms/W$$$$yrs%BaselineBaseline78.041 W T12 & 0.95 BF Mag183.220.0013.960.00N/A0.0A: LampReplacementEL391.234 W T12 & 0.88 BF Mag164.5718.6625.137.081.6-10.3EL180.541 W T12 & 0.88 BF Elec196.61-13.3972.517.208.1-3.5EL182.941 W T12 & 0.87 BF Elec197.99-14.7677.167.438.5-2.7EL286.232.5 W T8 & 1.18 BF Elec196.23-13.0065.115.299.78.7EL287.841 W T12 & 0.87 BF Elec198.26-15.0377.457.438.53.3EL391.234 W T12 & 0.88 BF Elec177.875.3577.0612.605.0-10.3EL390.832.5 W T8 & 1 BF Elec178.514.7168.2110.665.1-1.0EL492.332.5 W T8 & 0.88 BF Elec158.4224.8060.9614.243.3-8.3EL493.830.4 W T8 & 1 BF Elec170.5012.7269.4913.064.3-2.0EL493.026.6 W T8 & 1.18 BF Elec167.1416.0973.2513.924.31.4EL595.432.5 W T8 & 0.88 BF Elec159.8423.3862.5214.243.4-6.2Event I: LampFailureB: Lamp &BallastReplacementEL596.028.4 W T8 & 1 BF Elec164.8718.3568.8915.183.6-6.4BaselineBaseline78.041 W T12 & 0.95 BF Mag176.540.0013.960.00N/A0.0EL180.541 W T12 & 0.88 BF Elec198.15-21.6274.827.208.5-3.5EL182.941 W T12 & 0.87 BF Elec199.53-22.9979.467.438.8-2.7EL286.232.5 W T8 & 1.18 BF Elec197.77-21.2367.425.2910.18.7EL287.841 W T12 & 0.87 BF Elec199.80-23.2679.767.438.93.3EL391.234 W T12 & 0.88 BF Elec179.42-2.8879.3712.605.2-10.3EL390.832.5 W T8 & 1 BF Elec180.05-3.5170.5210.665.3-1.0EL492.332.5 W T8 & 0.88 BF Elec159.9616.5763.2614.243.5-8.3EL493.830.4 W T8 & 1 BF Elec172.054.4971.8013.064.4-2.0EL493.026.6 W T8 & 1.18 BF Elec168.687.8675.5613.924.41.4EL595.432.5 W T8 & 0.88 BF Elec161.3915.1564.8314.243.6-6.2Event II:StandardsInduced RetrofitLamp & BallastReplacementEL596.028.4 W T8 & 1 BF Elec166.4210.1271.1915.183.8-6.412-33Table 12.3.21 LCC and PBP Results for a Three-Lamp 4-Foot 40W T12 MBP System Operating in Institutions That ServeLow-Income Populations (continued)EventResponseEfficacy LevelRatedLampEfficacyDesign OptionLCCLCC SavingsInstalledPriceOperatingCostSavings(StartYear)PaybackPeriod% MeanLumensfromBaselinelms/W$$$$yrs%BaselineBaseline78.041 W T12 & 0.88 BF Elec190.000.0065.890.00N/A-7.4*EL180.541 W T12 & 0.87 BF Elec195.72-5.7372.510.2328.9-4.6EL182.941 W T12 & 0.87 BF Elec197.99-7.9977.160.2349.2-2.7EL287.841 W T12 & 0.87 BF Elec198.26-8.2677.450.2350.53.3EL391.234 W T12 & 0.88 BF Elec177.8712.1277.065.402.1-10.3EL390.832.5 W T8 & 1 BF Elec178.5111.4968.213.460.7-1.0EL492.332.5 W T8 & 0.88 BF Elec158.4231.5760.967.040.0-8.3EL493.830.4 W T8 & 1 BF Elec170.5019.4969.495.850.6-2.0EL493.026.6 W T8 & 1.18 BF Elec167.1422.8673.256.721.11.4EL595.432.5 W T8 & 0.88 BF Elec159.8430.1562.527.040.0-6.2Event III:Ballast FailureLamp & BallastReplacementEL596.028.4 W T8 & 1 BF Elec164.8725.1268.897.980.4-6.4BaselineBaseline/EL286.232.5 W T8 & 1.18 BF Elec197.770.0067.420.00N/A8.7EL391.234 W T12 & 0.88 BF Elec179.4218.3579.377.311.6-10.3EL390.832.5 W T8 & 1 BF Elec180.0517.7270.525.370.6-1.0EL492.332.5 W T8 & 0.88 BF Elec159.9637.8163.268.960.0-8.3EL493.830.4 W T8 & 1 BF Elec172.0525.7271.807.770.6-2.0EL493.026.6 W T8 & 1.18 BF Elec168.6829.0975.568.630.91.4EL595.432.5 W T8 & 0.88 BF Elec161.3936.3864.838.960.0-6.2Event IV:Ballast RetrofitLamp & BallastReplacementEL596.028.4 W T8 & 1 BF Elec166.4231.3571.199.890.4-6.4* Comparative lumens are sometimes non-zero for baseline T12 electronic systems under Event Type 3 and 4 (ballast failure and retrofit) because the lumen package is compared to a system with a T12magnetic ballast.

# 12.3.4 C onsumers of T12 Electronic Ballasts

DOE analyzed the LCC savings of a consumer that owns a T12 electronic system in the

base case. In the case of an energy conservation standard at EL4 or EL5, this consumer must

purchase a T8 electronic system as T12 lamps are no longer available. DOE established a new

baseline electronic T12 system and modified standards case systems so that both light output is

maintained in the case of a standard and energy is saved. All other factors of the LCC subgroup

analysis remained the same as in the primary analysis. Because electronic T12 systems are much

more efficacious than T12 magnetic systems, the LCC savings for this subgroup are lower than

the LCC savings for systems in the primary analysis. For 4-foot MBP lamps operating in the

commercial sector, LCC savings are reduced by approximately $20 to $30 going from positive

LCC savings in the primary analysis to negative LCC savings for this subgroup. The source of

this reduction is primarily due to the increased efficacy of the baseline system.

12.3.4.1 Product class: 4-foot MBP ≤4,500K

Table 12.3.34 and Table 12.3.35 show LCC and PBP results for 4-foot MBP 40W T12

and 34W T12 electronic systems in the commercial sector. Table 12.3.36 shows a summary of

the LCC results for both baselines. It is not possible for consumers of T12 electronic ballasts to

achieve positive LCC savings at EL4 or EL5 when purchasing T8 electronic systems. LCC

savings are approximately $20 to $30 less than the LCC savings experienced by consumers of 4-

foot MBP magnetic baseline systems in the primary LCC analysis.12-50Table 12.3.34 LCC and PBP Results for a Three-Lamp 4-Foot 40W T12 Electronic MBP System Operating in the CommercialSectorEventResponseEfficacy LevelRatedLampEfficacyDesign OptionLCCLCC SavingsInstalledPriceOperatingCostSavings(StartYear)PaybackPeriod% MeanLumensfromBaselinelms/W$$$$yrs%BaselineBaseline78.041 W T12 & 0.88 BF Elec164.360.0013.960.00N/A-7.4EL492.332.5 W T8 & 0.88 BF Elec168.73-4.3763.267.047.0-8.3EL493.830.4 W T8 & 1 BF Elec181.08-16.7271.805.859.9-2.0EL493.026.6 W T8 & 1.18 BF Elec176.46-12.0975.566.729.21.4EL595.432.5 W T8 & 0.88 BF Elec170.12-5.7664.837.047.2-6.2Event II:StandardsInduced RetrofitLamp & BallastReplacementEL596.028.4 W T8 & 1 BF Elec174.35-9.9871.197.987.2-6.4Table 12.3.35 LCC and PBP Results for a Three-Lamp 4-Foot 34W T12 Electronic MBP System Operating in the CommercialSectorEventResponseEfficacy LevelRatedLampEfficacyDesign OptionLCCLCC SavingsInstalledPriceOperatingCostSavings(StartYear)PaybackPeriod% MeanLumensfromBaselinelms/W$$$$yrs%BaselineBaseline77.934 W T12 & 0.88 BF Elec139.630.0011.220.00N/A0.0EL492.332.5 W T8 & 0.75 BF Elec152.01-12.3863.265.529.45.6EL493.830.4 W T8 & 0.78 BF Elec150.18-10.5464.116.588.03.3EL493.026.6 W T8 & 0.88 BF Elec141.06-1.4367.888.486.72.2EL595.432.5 W T8 & 0.71 BF Elec148.26-8.6364.836.728.02.3Event II:StandardsInduced RetrofitLamp & BallastReplacementEL596.028.4 W T8 & 0.78 BF Elec145.17-5.5363.518.306.3-1.3

# Table 12.3.37 shows the LCC and PBP results for consumers of 40W T12 electronic

s ystems in the residential sector. Table 12.3.38 shows a summary of the LCC results for this

subgroup. Only results for residential high operating hours apply because the lamp failure event

in the residential sector only occurs in the case of high operating hours. The lamp and ballast

replacement event in the residential sector is similar to a standards-induced retrofit in the

commercial sector, though DOE assumes that residential consumers will not replace their

systems before a lamp failure occurs. Consumers of 4-foot T12 MBP electronic systems in the

residential sector cannot achieve positive LCC savings when switching to T8 systems. LCC

savings are approximately $5 less than the LCC savings experienced by consumers of 4-foot

MBP magnetic systems in the primary LCC analysis.12-53Table 12.3.37 LCC and PBP Results for a Two-Lamp 4-Foot 40W T12 Electronic MBP System Operating in the ResidentialSector With High Operating HoursEventResponseEfficacy LevelRatedLampEfficacyDesign OptionLCCLCC SavingsInstalledPriceOperatingCostSavings(StartYear)PaybackPeriodlms/W$$$$yrsBaselineBaseline76.841 W T12 & 0.65 BF Elec21.750.003.980.00N/AEL492.332.5 W T8 & 0.75 BF Elec30.10-8.3550.991.1441.1EL493.830.4 W T8 & 0.75 BF Elec29.54-7.7851.561.4732.5EL493.026.6 W T8 & 0.78 BF Elec28.21-6.4554.072.3821.0EL595.432.5 W T8 & 0.71 BF Elec29.56-7.8052.031.5231.6Event I: LampFailureLamp & BallastReplacementEL596.028.4 W T8 & 0.78 BF Elec28.93-7.1851.161.6828.0Table 12.3.38 Summary of LCC Results for a Two-Lamp 4-Foot Electronic MBP System Operating in the Residential SectorWith High Operating HoursLCC Savings2007$Installed Price2007$Baseline Efficacy LevelEvent IB: Lamp & Ballast ReplacementBaselineN/A3.98EL1EN/AEN/AEL2EN/AEN/AEL3EN/AEN/AEL4-8.35 to -6.45 50.99 to 54.0740 Watt T12EL5-7.80 to -7.18 51.16 to 52.03*Analysis period is 2.5 years.EN/A: Event Not Applicable; N/A: Not Applicable
