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

12.1 INTRODUCTION

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

examines impacts of energy conservation standa rds on the U.S. population. In analyzing the

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

on identifiable groups of consumers (i.e., consum er 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) a nd incandescent reflector lamps (IRL), DOE

identified four consumer subgroups that warr anted further study: lo w-income consumers,

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

of T12 electronic ballasts. The analysis determ ines whether these groups of consumers would be

adversely affected by any of th e trial standard levels.

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

spreadsheet model, which allows for the exam ination 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 f or 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 INPU TS TO THE S UB-GROUP ANALYSIS

DOE researched the subgroups by utilizing the 2005 RECS i 

# and 2003 CBECS ii



# databases as well as the 2002 U.S. Li ghting Market Characterization (LMC) iii 

# . DOE also used

financial sources as described be low. To explore institutions that serve low-income populations,

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

# defined low-income consumers as residential co nsumers 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 lin e varies with household size, h ead of household age, and family

income. Table 12.2.1 summarizes the criteria given for se lecting low-incom e households from

the 2005 RECS database; households with incomes below the weighted-ave rage threshold were

considered to be low-income households.

12-1

# Table 12.2.1 U.S. Census Bureau 2005 Defi nition of Low-Income Households

1 65 and over $9.367

5 Any $23,613

6 Any $26,683

7 Any $30,249

8 Any $33,610

9 or more Any $40,288

DOE discovered that residentia l low-income consumers faced el ectricity 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 num ber 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 residentia l electricity price of approximately $0.117. DOE

then used this price as a modification to the resi dential-sector primary LC C analysis. Because of

the large diversity of low-income families in th e residential sector, DOE does not expect to see

differences in other inputs like oper ating 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 resi dential sector population.

12.2.2 Institutions of Religious Worship

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

any other building type in the commercial se ctor 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 na tion. 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, instituti ons of religious worship operate

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

operating hours for these instituti ons are significantly different than the operating hours for the

typical commercial consumer, DOE modified th e commercial-sector primary LCC analysis by

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

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

inputs like electricity prices, or sales tax that vary significantl y 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 us ed for the general commercial

sector population.

12.2.3 Institutions That Serve Low-Income Populations

DOE also perform ed research on instituti ons that serve low-income populations and

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

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

types, or event response behavior s that vary significantly on averag e from the commercial sector

as a whole. DOE, however, expe cts that the majority of orga nizations serving low-income

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

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

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

business subgroups in the Cooking Products and Commercial Cl othes Washers NOPR

analysis, viii 

# as described below.

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

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

model (CAPM) used in Chapter 8 for the gene ral 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 signi ficantly higher than the CAPM e quation predicts. This additional

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

# 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 i ndustries is 6.27 percent, implyi ng that on average, historic

performance of small companies has been 6.27 pe rcent 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 averag e discount rate for small companie s in the entire U.S. market

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

average cost of capital as described in Chapte r 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

Entire Market, Small 10.2% 3.3% 3.8%

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

7.0 percent. Applying the additi onal 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 percen t. 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 asp ects of the subgroup LCC

analysis the same as in the comm ercial-sector primary LCC analysis.

12.2.4 Consumers of T12 Electronic Ballasts

DOE analyzed consum ers of T12 electronic ballasts as a consumer subgroup because

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

those consumers with magnetic systems particular ly 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 a nd 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 a nd industrial sectors, DOE analyzed consumers who

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

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

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

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

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

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

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

companies.

12-4

# 12-5 

# failure event, where consumers faced with a T 12 lamp failure replace their entire functioning

system with a T8 system. Because the T12 el ectronic 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 ba seline 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 ot her 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 LC C 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 desc ribed 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-incom e 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 ac ronyms 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 a nd 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 re sidential consumers. This also causes the

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

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

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

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

analysis period. Thus, any equipment or insta llation costs incurred by co nsumers in the middle

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

further details on GSFL consumer be havior in the residential sector.Table 12.3.1 LCC and PBP Results for a Two-Lamp 4-Foot 40W T12 MBP3System Operating in the Low-Income ResidentialSector With

# 12.3.2 Institutions of Religious Worship

DOE researched institutions of religious wors hip and discovered that these institutions

had the lowest operating hours of any non-mall co mmercial 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 institutio ns of religious worship is id entical to the main commercial

sector LCC analysis except for lower operating hours, re sulting 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 re st of the commercial se ctor, particularly for

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

operating cost savings to be di scounted 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 system s with color co rrelated 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 Replacemen t) and Event II across the 40W and 34W T12

baseline lamps, institutions of religious worship typically experi ence 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 Even t IA (Lamp Replacement) and Event III (as well

as Event V for the 32W T8 baseline), instituti ons 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 institu tions of religious wors hip are several decades

longer than in the primary commercial sector an alysis, 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 ar e positive in the prim ary 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 savi ngs are negative for EL3, in contrast to the

positive LCC results in the primary commercial-sect or analysis. Similarly, Event II LCC savings

for the 40W T12 baseline in institutions of relig ious 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

For Event I, institutions of religious wors hip 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 s ubgroup 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.

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 inst itutions of religious

positive for these baselines and this subgroup except for the EL5 60W T8 system in Event II for

the 75W T12 baseline. LCC sa vings in institutions of re ligious 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 increa sed by a decade for most system options. For

EL3 in Event II for the 75W and 60W T12 ba selines, 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

# 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 la mps operating in instit utions of religious

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

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

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

approximately half a year. For EL1 in th e 90W and 75W PAR38 baselines, however, LCC

savings are increased for institutions of religio us worship. This is because in the primary

commercial-sector analysis, the lamp at EL1 is purc hased twice in the first analysis year. In the

analysis for institutions of relig ious 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 savi ngs are increased for this subgroup at EL1.

# 12.3.3 Institutions That Serve Low-Income Populations

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

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

discount rate for the primary comm ercial 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, instituti ons that serve low-income popul ations 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 lo wer than for the rest of the

commercial sector. For IRL, LC C savings are several cents lowe r 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 subgr oup, except in specific

instances described below. The payback periods for this subgroup are id entical to the payback

periods in the commercial-sector LCC analysis because DOE computes simple PBPs, which do

not take into account discounting; thus, change s 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 incom e populations are shown in Table 12.3.25 through Table 12.3.27. In

com parison with the primary commercial-sector anal ysis, LCC savings for institutions that serve

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

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

savings are approximately 4 dollars.

For all three baselines, LCC savings that ar e positive in the primar y 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 th is subgroup. In the 34W T12 baseline, the 32W

# 12.3.4 Consumers of T12 Electronic Ballasts

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

base case. In the case of an energy conservati on standard at EL4 or EL 5, this consumer must

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

baseline electronic T12 system and modified st andards case systems so th at 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 an alysis. Because electronic T12 systems are much

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

the LCC savings for systems in the primary anal ysis. 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 negati ve LCC savings for this subgroup. The source of

this reduction is primarily due to the incr eased 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 po ssible for consum ers of T1 2 electronic ballasts to

achieve positive LCC savings at EL4 or EL5 wh en 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 system s 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 ho urs apply for consumers who do not pr eserve their lamps because the lamp failure

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

electronic baseline ballasts who preserve thei r 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 consumer s are approximately $5 less than the LCC

savings experienced by residentia l-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 consum ers 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

# 12.3.4.2 Product class: 8-foot SP slimline ≤ 4,500K

Table 12.3.47 and Table 12.3.48 show the LCC and PBP results for consumers of 8-foot

SP slim line 75W T12 and 60W T12 el ectronic systems, respectively. Table 12.3.49 shows a

summary of LCC results for both baselines. C onsum ers of 8-foot T12 electronic SP slimline

systems cannot achieve positive LCC savings when switching to T8 systems. LCC savings for

consumers of the 75W T12 electronic baseline system are approximately $35 less than

consumers of the magnetic 75W T12 baseline system in the primary LCC analysis. In

comparison to consumers of the magnetic 60W T12 baseline system in the primary LCC

analysis, LCC savings for consumers of th e 60W T12 electronic baseline system are

approximately $25 less for the available EL4 system.
