CHAPTER 12. LIFE-CYCLE COST SUB-GROUP ANALYSIS 

12.1 INTRODUCTION 

Chapter 8 describes the life-cycle cost (LCC) and payback period (PBP) analysis that 

examines 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., consumer 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, 

institutions of religious 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 2005 RECSi

 and 2003 CBECSii 

databases as well as the 2002 U.S. Lighting Market Characterization (LMC)iii. DOE also used 

financial sources 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. 

12.2.1 Low-Income Consumers 

The Residential Furnaces and Boilers Notice of Proposed Rulemakingiv, Central Air 

Conditioners Supplemental Notice of Proposed Rulemakingv

, and Clothes Washers Final Rulevi

defined low-income consumers as residential consumers with incomes at or below the poverty 

line as defined by the U.S. Census Bureau.vii 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 2005 RECS database; households with incomes below the weighted-average threshold were 

considered to be low-income households.

6 Any $26,683 

7 Any $30,249 

8 Any $33,610 

9 or more Any $40,288 

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

lower by 0.2 cents per kWh (in 2005 dollars) than the prices faced by consumers above the 

poverty line in 2005, 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 $0.119 (2008$) by 0.096/0.098 (approximately 

0.9814) to arrive at the low-income residential electricity price of approximately $0.117. 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 LMC and 2003 CBECS. The 

12-2
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 

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 are 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,viii as 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: 

 Rk fe      SERP

ke = Cost of equity, 

Rf = Expected return on risk-free assets, 

β = Risk coefficient of the firm, 

ERP = Equity risk premium, and 

S = Size Premium. 

12-3
DOE obtained size premium data from Ibbotson Associates’ Stocks, Bonds, Bills, and 

Inflation 2007 Yearbook.

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

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

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

small 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, x

Table 12.2.3 Discount Rate Difference Between Small Company and Market Average 

Discount Rate 

Sector Average Std Dev Difference 

Entire Market 6.3% 2.3% -- 

Entire Market, Small 10.2% 3.3% 3.8% 

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. DOE kept all other aspects of the subgroup LCC 

analysis the same as in 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 

 

1

 In this calculation, small companies are defined as companies with market capitalization of less than or equal to 

$84.5 million, the Ibbotson Associates’ definition of Decile 10 companies. 2

 The Damodaran database for the entire market included 6559 companies total, 2605 of which were small 

companies. 

12-4

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 

electronic systems, 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. 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 through Table 12.3.4 for GSFL and in Table 12.3.9 through Table 12.3.11

for IRL. Table 12.3.5 and Table 12.3.6 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 

payback periods to be longer, by up to several months, for low-income residential consumers. 

Note that the payback periods for lamp-preserving GSFL consumers do not accurately reflect the 

economic benefits or burdens that these consumers experience, because DOE uses “simple 

payback periods” that only incorporate installed costs incurred at the very beginning of the 

analysis period. Thus, any equipment or installation costs incurred by consumers in the middle 

of the analysis period are not reflected in the payback period computation. See Chapter 8 for 

further details on GSFL consumer behavior in the residential sector.

12.3.2 Institutions 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 12.3.12 through Table 

12.3.14. 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 15 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 of some systems 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, for 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 T8 replacement system at EL3 and the 32W and 30W T8 replacement systems at EL4 and 

EL5. LCC savings for the 32W T8 baseline remain positive for institutions of religious worship. 

Table 12.3.15 shows summary results for all three 4-foot MBP baselines.

* 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 magnetic ballast. DOE chose to compare these systems for these events because it recognizes that though federal regulations will prohibit the use of magnetic ballasts, current lumen package delivered by current T12 magnetic systems.

12.3.2.2 Product class: 4-foot T5 miniature bipin standard output ≤4,500K 

Table 12.3.16 presents the results for an electronically ballasted 4-foot T5 miniature bipin 

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

For Event I, institutions of religious worship face LCC savings that are approximately $1.50 

lower than the rest of the commercial sector, with a payback period approximately 5 years 

longer. The LCC savings at Event I for this subgroup are negative. LCC savings are positive for 

all other events and systems, as in the primary commercial-sector analysis. For Events III and V, 

LCC savings are up to 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 12.3.17 shows a summary of the LCC and PBP results for the 4-

foot T5 MiniBP SO baseline system operating in institutions of religious worship.

12.3.2.3 Product class: 8-foot single pin slimline ≤4,500K 

Table 12.3.18 through Table 12.3.20 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 60W T8 system in Event II for 

the 75W T12 baseline. LCC savings in institutions of religious worship are reduced by 

approximately 17 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 40 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 12.3.21 shows a summary of the LCC and PBP 

results for 8-foot SP slimline systems in institutions of religious worship.

12.3.2.4 Incandescent reflector lamps 

Table 12.3.22 through Table 12.3.24 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 half a 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.

12.3.3 Institutions 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 are 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. Positive primary LCC results generally remained positive for this subgroup 

while negative primary LCC results remained negative for this subgroup, except in specific 

instances described below. 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 12.3.25 through Table 12.3.27. 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 4 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 12.3.28 shows summary results for all three 4-foot MBP baselines.

Table 12.3.29 presents the results for an electronically-ballasted 4-foot T5 MiniBP SO 

baseline system operating in institutions that serve low-income populations. LCC savings are all 

positive for this baseline lamp and subgroup, as in the primary commercial sector LCC analysis. 

For Event IA, LCC savings are approximately 1 dollar lower than in the rest of the commercial 

sector. For Events III and V, LCC savings are up to approximately 5 dollars lower for 

institutions that serve low-income populations. Table 12.3.30 shows a summary of the LCC and 

PBP results for the 4-foot T5 MiniBP SO baseline system operating in these institutions.

Table 12.3.31 through Table 12.3.33 present the results for the 75W T12, 60W T12, and 

59W T8 8-foot SP slimline baseline systems operating in institutions that serve low-income 

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

positive for these baselines and this subgroup except for the EL5 60W T8 replacement system 

for the 75W baseline at Event II. LCC savings in institutions that serve low-income populations 

are reduced by approximately 7 to 10 dollars for Events IB and II for the 75W and 60W T12 

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

up to approximately 3 dollars in these institutions. Table 12.3.34 shows a summary of the LCC 

results for 8-foot SP slimline systems in institutions that serve low-income populations.

12.3.4 Consumers 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 12.3.38 and Table 12.3.39 show LCC and PBP results for 4-foot MBP 40W T12 

and 34W T12 electronic systems in the commercial sector. Table 12.3.40 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.

Table 12.3.41 through Table 12.3.43 show the LCC and PBP results for consumers of 

40W T12 electronic baseline systems in the residential sector. Table 12.3.44 through Table 

12.3.46 show a summary of the LCC results for this subgroup. Only results for residential high 

operating hours apply for consumers who do not preserve their lamps because the lamp failure 

event for these consumers only occurs in the case of high operating hours. For consumers of T12 

electronic baseline ballasts who preserve their lamps, DOE produces LCC and PBP results at 

both high and average operating hours. See Chapter 8 for a discussion of residential-sector 

GSFL consumer behavior. 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. 

LCC savings for non-lamp-preserving consumers are approximately $5 less than the LCC 

savings experienced by residential-sector consumers of 4-foot MBP baseline magnetic systems 

in the primary LCC analysis; as in the primary LCC analysis, the LCC savings for this consumer 

subgroup remain negative. LCC savings for lamp-preserving consumers operating at high 

operating hours are approximately $18 less than the LCC savings experienced by consumers of 

4-foot MBP baseline magnetic systems in the primary LCC analysis. LCC savings remain 

positive for these consumers except for with the 32W T8 system at EL4. LCC savings for lamppreserving consumers operating at average operating hours are approximately $15 less than the 

LCC savings experienced by consumers of 4-foot MBP baseline magnetic systems in the primary 

LCC analysis. LCC savings remain negative.
