APPENDIX 8B. SUPPLEMENTARY LIFE-CYCLE COST AND PAYBACK PERIOD 

RESULTS

8B.1 INTRODUCTION

This appendix discusses uncertainty and variability analyses and presents results of those

uncertainty and variability analyses performed in the life-cycle cost (LCC) and payback period 

(PBP) analysis. Results for the life-cycle cost and payback period analysis using a distribution of 

operating hours, discount rates, sales tax, and electricity prices are presented. The average LCC

savings at each efficacy level (EL) for each lamp or lamp-and-ballast design is given along with 

the percentage of consumers who would experience a net benefit or net loss by purchasing a 

standards-case design instead of a base0case design. The median and mean PBP are also given.

This appendix also presents results of the LCC and PBP analysis using high and low lamp prices.

For general service fluorescent lamps (GSFL), results using medium-range lamp prices and no 

ballast price (where the price of the ballast is set equal to zero during the analysis) are also 

presented. For residential incandescent reflector lamps (IRL), results using high operating hours 

(1,210 hours/year: the average operating hours of a lamp placed in the kitchen of a single-family 

detached home) and low operating hours (183 hours/year: the average operating hours of a lamp 

placed in a closet of a multi-family 2-4 unit home) are presented. These operating hours are 

obtained from the U.S. Lighting Market Characterization: Volume I.

8B.2 INTRODUCTION TO UNCERTAINTY AND VARIABILITY

 Finally, this appendix 

presents the LCC and PBP analysis results using high- and low-economic-growth electricity 

price trends that were generated using the Energy Information Administration’s (EIA’s) March 

2009 and April 2009 Annual Energy Outlook 2009 (AEO2009) datasets. The April 2009 

AEO2009 includes the impact of the American Recovery and Reinvestment Act of February 

2009 (Pub. L. 111-5).

Analysis of an energy-efficiency standard involves calculations of impacts, such as the 

impact of a standard on consumer LCC. In order to perform the calculation, the analyst must 

first: 1) specify the equation or model that will be used; 2) define the quantities in the equation; 

and 3) provide numerical values for each quantity. In the simplest case, the equation is 

unambiguous (contains all relevant quantities and no others), each quantity has a single 

numerical value, and the calculation results in a single value. However, certainty and precision 

are rarely the case. In almost all cases, the model and/or the numerical values for each quantity 

in the model are not completely known (i.e., there is uncertainty) or the model and/or the 

numerical values for each quantity in the model depend upon other conditions (i.e., there is 

variability).

Thorough analysis involves accounting for uncertainty and variability. While the 

simplest analysis involves a single numerical value for each quantity in a calculation, arguments 

can arise about what the appropriate value is for each quantity. Explicit analysis of uncertainty 
8B-2

and variability is intended to provide more complete information for the decision-making 

process.

8B.3 UNCERTAINTY

When making observations of past events or speculating about the future, imperfect 

knowledge is the rule rather than the exception. For example, the energy actually consumed by a 

particular appliance type (such as the average U.S. lamp) is not directly recorded, but rather 

estimated based upon available information. Even direct laboratory measurements have some 

margin of error. When estimating numerical values expected for quantities at some future date, 

the exact outcome is rarely known in advance.

8B.4 VARIABILITY

Variability means that different applications or situations produce different numerical 

values when calculating a quantity. Specifying an exact value for a quantity may be difficult 

because the value depends on something else. For example, the number of hours a lamp is 

operated by a household depends upon the specific circumstances and behaviors of the occupants 

(e.g., number of persons, personal habits about how much light the person needs, etc.). 

Variability makes specifying an appropriate population value more difficult in as much as any 

one value may not be representative of the entire population. Surveys can be helpful here, and 

analysis of surveys can relate the variable of interest (e.g., hours of use) to other variables that 

are better known or easier to forecast (e.g., persons per household).

8B.5 APPROACHES TO UNCERTAINTY AND VARIABILITY

This section describes two approaches to uncertainty and variability: 

• scenario analysis, and 

• probability analysis.

Scenario analysis uses a single numerical value for each quantity in a calculation, then 

changes one (or more) of the numerical values and repeats the calculation. A number of 

calculations are done, which provide some indication of the extent to which the result depends 

upon the assumptions. For example, the life-cycle cost of a lamp could be calculated for energy 

rates of 2, 8, and 14¢ per kilowatt-hour (kWh). 

The advantages of scenario analysis are that each calculation is simple; a range of 

estimates is used; and crossover points can be identified. (An example of a crossover point is the 

energy rate above which the life-cycle cost is reduced, holding all other inputs constant. That is, 

the crossover point is the energy rate at which the consumer achieves savings in operating 
8B-3

expense that more than compensate for the increased purchase expense.) The disadvantage of 

scenario analysis is that there is no information about the likelihood of each scenario.

Probability analysis considers the probabilities within a range of values. For quantities 

with variability (e.g., electricity rates in different households), surveys can be used to generate a 

frequency distribution of numerical values (e.g., the number of households with electricity rates 

at particular levels) to estimate the probability of each value. For quantities with uncertainty, 

statistical or subjective measures can be used to provide probabilities (e.g., manufacturing cost to 

improve energy efficiency to some level may be estimated to be $10 ± $3). 

The major disadvantage of the probability approach is that it requires more information, 

namely information about the shapes and magnitudes of the variability and uncertainty of each 

quantity. The advantage of the probability approach is that it provides greater information about 

the outcome of the calculations, that is, it provides the probability that the outcome will be in a 

particular range. 

Scenario and probability analysis provide some indication of the robustness of the policy 

given the uncertainties and variability. A policy is robust when the impacts are acceptable over a 

wide range of possible conditions.

8B.6 PROBABILITY ANALYSIS AND THE USE OF CRYSTAL BALL

To quantify the uncertainty and variability that exist in inputs to the engineering, LCC, 

and payback period analyses, the DOE used Microsoft Excel spreadsheets combined with Crystal 

Ball, a commercially-available add-in application, to conduct probability analyses. The 

probability analyses used Monte Carlo simulation and probability distributions.

Simulation refers to any analytical method meant to imitate a real-life system, especially 

when other analyses are too mathematically complex or too difficult to reproduce. Without the 

aid of simulation, a spreadsheet model will only reveal a single outcome, generally the most 

likely or average scenario. Spreadsheet risk analysis uses both a spreadsheet model and 

simulation to automatically analyze the effect of varying inputs on outputs of the modeled 

system. One type of spreadsheet simulation is Monte Carlo simulation, which randomly 

generates values for uncertain variables again and again to simulate a system. Monte Carlo 

simulation was named for Monte Carlo, Monaco, where the primary attractions are casinos 

containing games of chance. Games of chance, such as roulette wheels, dice, and slot machines, 

exhibit random behavior. The random behavior in games of chance is similar to how Monte 

Carlo simulation utilizes variable values at random to simulate a model. For example, one knows 

that a rolled die will present a 1, 2, 3, 4, 5, or 6 after coming to rest, but one does not know 

which value will be presented on any particular roll. It is the same with the variables that have a 

known range of values but an uncertain value for any particular time or event (e.g., equipment 

lifetime, discount rate, and installation cost). 
8B-4

NORMAL

For each uncertain variable (one that has a range of possible values), possible values are defined 

with a probability distribution. The type of distribution selected is based on the conditions 

surrounding that variable. Probability distribution types include: 

During a simulation, multiple scenarios of a model are calculated by repeatedly sampling values 

from the probability distributions for the uncertain variables and using those values in the 

simulation. Crystal Ball simulations can consist of as many trials (or scenarios) as desired—

hundreds or even thousands. During a single trial, Crystal Ball randomly selects a value from the 

defined possibilities (the range and shape of the probability distribution) for each uncertain 

variable and then recalculates the spreadsheet. 

8B.7 GENERAL SERVICE FLUORESCENT RESULTS

DOE analyzed five product classes for GSFL: 4-foot medium bipin, 4-foot T5 miniature 

bipin standard output, 4-foot T5 miniature bipin high output, 8-foot single-pin slimline, and 8-

foot recessed double contact high-output, all with a correlated color temperature (CCT) less than 

or equal to 4,500 Kelvin (K). For each of the five product classes, DOE conducted both 

probability analyses (based on Monte Carlo runs) and scenario analyses. 

8B.7.1 Monte Carlo Results

To characterize the LCC savings and Monte Carlo results for GSFL, DOE developed 

tables to describe the distributions of the results. These tables document the average LCC 

savings and percentages of building analyzed with positive and negative LCC savings for various 

systems in each event analyzed. In addition, to characterize the distribution of payback periods, 

DOE reports the median and average payback period for each system analyzed for each event.

8B.7.1.1 Product Class: 4-foot medium bipin ≤ 4,500K

For the 4-foot medium bipin product class with CCT less than or equal to 4,500K in the 

commercial sector, DOE analyzed three baseline lamps: a 40W T12, 34W T12, and 32W T8. 

For each baseline, standards-compliant systems were analyzed at five efficacy levels with

the LCC savings and PBP Monte Carlo results for the three 4-foot medium bipin baselines 

operating in the commercial sector. Key inputs consist of using the April 2009 AEO2009

reference case electricity prices and medium-range lamp and ballast prices. Note: Lamp 

replacement results in Event I are not shown for a 34W T12 lamp because there are no energy 

saving lamp replacement options.

lamp diameter (e.g., T12), the third is the ballast factor of the ballast (e.g., 0.95 BF), and the fourth is the ballast type (e.g., “Mag” for Magnetic or “Elec” for 

Electronic).

* Comparative lumens are sometimes non-zero for baseline T12 electronic systems under events III and IV (ballast failure and retrofit) because the lumen 

package is compared to a system with a T12 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, future purchasers may still seek the current lumen package delivered by current T12 magnetic systems.

For the 4-foot medium bipin product class with CCT less than or equal to 4,500K in the residential sector, DOE analyzed one 

baseline lamp: a 40W T12. Standards-compliant replacement systems were analyzed at five efficacy levels with minimum efficacy 

requirements of 78, 81, 85, 89, and 93 lm/W. The following tables present the LCC savings and PBP Monte Carlo results for this 4-

foot medium bipin baseline operating in the residential sector. Key inputs consist of using the April 2009 AEO2009 reference case 

electricity prices and medium-range lamp and ballast prices. For the lamp failure event, residential high and average operating hours 

were used for consumers who preserve their lamps, while only residential high operating hours were used for consumers who do not 

preserve their lamps; the analysis periods are 12.4, 19, and 2.6 years, respectively. For other events, only residential average operating 

hours were used; the analysis period is 15 years. See Chapter 8 for further details on residential-sector GSFL consumer behavior.

8B.7.1.5 Product Class: 8-foot recessed double contact high output ≤ 4,500K

For the 8-foot recessed double contact HO operating in the industrial sector with CCT less than or equal to 4,500K, DOE 

analyzed two baseline lamps: a 110W T12 and 95W T12. For each baseline, standards-compliant replacement systems were analyzed 

at five efficacy levels with minimum efficacy requirements of 83, 86, 88, 92, and 95 lm/W. The following tables present the LCC 

savings and PBP Monte Carlo results for both of the 8-foot recessed double contact high output baselines operating in the industrial 

sector. Key inputs consist of using the April 2009 AEO2009 reference case electricity prices and medium-range lamp and ballast 

prices. Note: Lamp replacement results in Event I are not shown for a 95W T12 lamp because there are no energy saving lamp 

replacement options.

8B.7.2 Lamp and Ballast Price Scenario Results

As mentioned earlier, DOE also analyzed LCC savings and PBP results using a scenario 

analysis. Specifically, because the LCC and PBP results are highly dependent on equipment 

prices, DOE examined several sensitivities to the medium lamp price and ballast price results 

presented in Chapter 8. Chapter 7 described three prices (low, medium, and high) DOE 

developed for each general service fluorescent lamp. The following tables present LCC savings 

and PBP results using the low and high lamp prices. In addition, because DOE analyzes GSFL 

by considering both the lamp and the ballast, results presented in Chapter 7 account for the first 

cost of the ballast. However, as a sensitivity analysis, DOE presents LCC and PBP results 

assuming that the ballast price is equal to zero.

8B.7.2.1 Product Class: 4-foot medium bipin ≤ 4,500K

The following tables present the findings of an LCC analysis on the three 4-foot medium bipin

GSFL baselines operating in the commercial sector with a CCT less than or equal to 4,500K, 

considering low lamp prices, high lamp prices, or no ballast prices. Key inputs consist of using 

April 2009 AEO2009 reference case electricity prices and an analysis period of 5.5 yrs. Note:

Lamp replacement results in Event I are not shown for a 34W T12 lamp because there are no 

energy saving lamp replacement options.

package is compared to a system with a T12 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, future purchasers may still seek the current lumen package delivered by current T12 magnetic systems.

* Comparative lumens are sometimes non-zero for baseline T12 electronic systems under events III and IV (ballast failure and retrofit) because the lumen 

package is compared to a system with a T12 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, future purchasers may still seek the current lumen package delivered by current T12 magnetic systems.

For the 4-foot medium bipin product class with CCT less than or equal to 4,500K in the residential sector, DOE analyzed one 

baseline lamp: a 40W T12. The following tables present the LCC savings and PBP results for this 4-foot medium bipin baseline

operating in the residential sector with high lamp prices, low lamp prices, and no ballast price. Key inputs consist of using the April 

2009 AEO2009 reference case electricity prices. For the lamp failure event, residential high and average operating hours were used 

for consumers who preserve their lamps, while only residential high operating hours were used for consumers who do not preserve 

their lamps; the analysis periods are 12.4, 19, and 2.6 years, respectively. For other events, only residential average operating hours 

were used; the analysis period is 15 years.

8B.7.2.5 Product Class: 8-foot recessed double contact HO ≤ 4,500K

The following tables present the findings of an LCC analysis on the two 8-foot recessed double contact high output GSFL 

baselines operating in the industrial sector, considering low lamp prices, high lamp prices, or no ballast prices. Key inputs consist of 

using April 2009 AEO2009 reference case electricity prices and an analysis period of 2.3 years. Note: Lamp replacement results in 

Event I are not shown for a 95W T12 lamp because there are no energy saving lamp replacement options.

8B.7.3 Electricity Price Trend Case Results

Finally, DOE analyzed the impacts of high and low growth trends for future electricity 

prices, as lamp and lamp-and-ballast system operating costs are directly related to future 

electricity prices. Specifically, DOE examined the impacts of using high-economic-growth and 

low-economic-growth cases generated utilizing the March 2009 and April 2009 AEO2009

datasets. Chapter 8 describes and compares the three price trends. The following tables present 

LCC savings and PBP results using the low and high growth cases.

8B.7.3.1 Product Class: 4-foot medium bipin ≤ 4,500K

The following tables present the findings of an LCC analysis on the three 4-foot medium 

bipin GSFL baselines operating in the commercial sector with a CCT less than or equal to 

4,500K, considering AEO2009 high and low growth price trend cases. Key inputs consist of 

using medium lamp and ballast prices and an analysis period of 5.5 yrs. Note: Lamp 

replacement results in Event I are not shown for a 34W T12 lamp because there are no energy 

saving lamp replacement options.

* Comparative lumens are sometimes non-zero for baseline T12 electronic systems under events III and IV (ballast failure and retrofit) because the lumen 

package is compared to a system with a T12 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, future purchasers may still seek the current lumen package delivered by current T12 magnetic systems.

For the 4-foot medium bipin product class with CCT less than or equal to 4,500K in the residential sector, DOE analyzed one 

baseline lamp: a 40W T12. The following tables present the LCC savings and PBP results for this 4-foot medium bipin baseline

operating in the residential sector under the AEO2009 high and low growth electricity price trend cases. Key inputs consist of using

medium lamp and ballast prices. For the lamp failure event, residential high and average operating hours were used for consumers 

who preserve their lamps, while only residential high operating hours were used for consumers who do not preserve their lamps; the 

analysis periods are 12.4, 19, and 2.6 years, respectively. For other events, only residential average operating hours were used; the 

analysis period is 15 years.

8B.8 INCANDESCENT REFLECTOR RESULTS

DOE analyzed three IRL baselines in the commercial and residential sectors: a 90W 

PAR38 lamp, a 75W PAR38 lamp, and a 50W PAR30 lamp. For each of the three baselines, 

DOE conducts both probability analyses (based on Monte Carlo runs) and scenario analyses. 

8B.8.1 Monte Carlo Results

Similar to GSFL, to characterize the LCC savings and Monte Carlo results for IRL DOE 

developed tables to describe the results distributions. These tables document the average LCC 

savings and percentages of building analyzed with positive and negative LCC savings for each 

lamp design. In addition, to characterize the distribution of payback periods, DOE reports the 

median and average payback period for every lamp design and EL. The following tables present

the LCC savings and PBP Monte Carlo results for the three IRL baselines operating in the 

commercial and residential sectors. Key inputs consist of using the April 2009 AEO2009

reference case electricity prices and medium-range lamp prices.

8B.8.2 Lamp Price Scenario Results

As mentioned earlier, DOE also analyzed LCC savings and PBP results using a scenario analysis. Specifically, because the 

LCC and PBP results are highly dependent on equipment prices, DOE examined several sensitivities to the medium lamp price results 

presented in Chapter 8. Chapter 7 described three prices (low, medium, and high) DOE developed for each IRL lamp design. The 

following tables present the findings of the LCC and PBP analyses on the three IRL baselines operating in the commercial and 

residential sectors, considering low lamp prices and high lamp prices. Key inputs consist of using April 2009 AEO2009 reference case 

electricity prices, average operating hours in each sector, and an analysis period of 0.9 years in the commercial sector and 3.4 years in

8B.8.3 Operating Hour Scenario Results

In addition to analyzing lamp price sensitivities to the analysis, DOE also analyzes LCC and PBP sensitivities to operating 

hours. As discussed earlier, Monte Carlo results take into account distributions in operating hours across building types. Specifically, 

because the LCC and PBP results are highly dependent on equipment prices, DOE examined several sensitivities. However, in the 

residential sector, because there is a large range of hours across room types (not depicted in the operating hour distribution over 

building types) DOE analyzes high and low operating hour sensitivity LCC and PBP results. For residential incandescent reflector 
8B-151

lamps, results using high operating hours (1,210 hours/ year: the average operating hours of a lamp placed in the kitchen of a singlefamily detached home) and low operating hours (183 hours/ year: the average operating hours of a lamp placed in a closet of a multifamily 2-4 unit home) are presented. These operating hours were obtained from the U.S. Lighting Market Characterization: Volume 

I

ii

. The following tables depict these results for the residential sector using key inputs such as AEO2009 reference case electricity 

prices and average lamp prices. The high operating hour scenario uses an analysis period of 2.5 years and the low operating hour 

scenario uses an analysis period of 16.4 years.

8B.8.4 Electricity Price Trend Case Results

Because the LCC and PBP results for IRL are also highly dependent on electricity prices, DOE examined the impacts of the 

AEO2009 high and low growth electricity price trend cases. Chapter 8 describes the two cases and compares them with the April 

2009 AEO2009 reference case electricity price trend. The following tables present the findings of the LCC and PBP analyses on the 

three IRL baselines operating in the commercial and residential sectors, considering high and low growth cases. Key inputs consist of 
8B-157

using medium lamp prices, average operating hours in each sector, and an analysis period of 0.9 years in the commercial sector and 

3.4 years in the residential sector.
