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 preformed in the life cycle cost (LCC) and payback period

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

distribution of operating hours, discount rates, sales tax, and electricity prices are presented. The

average LCC savings at each candidate standard level (CSL) for each lamp or lamp­and­ballast

design are given as well as the percentage of consumers who would experience a net benefit or

net loss by purchasing a from a standards case design instead of a base case 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

medium­range lamp prices and no ballast price, where the price of the ballasts is equal to zero,

are also presented. For residential incandescent reflectors lamps (IRL) 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 2­4 unit home) are presented.

These operating hours are obtained U.S. Lighting Market Characterization: Volume I

8B.2 INTRODUCTION TO UNCERTAINTY AND VARIABILITY

Analysis of an energy­efficiency standard involves calculations of impacts, for example,

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, unambiguity 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

and variability is intended to provide more complete information to the decision­making process.

8B­1

EERE-2007-BT-TP-0013 COMMENT 05
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 life­cycle cost of a lamp could be calculated for energy

rates of 2, 8, and 14¢ per 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 life­cycle 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

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.

8B­2

EERE-2007-BT-TP-0013 COMMENT 05
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 (PBP) analyses, the Department used Microsoft Excel spreadsheets

combined with Crystal Ball, a commercially available add­in, to conduct probability analyses.

The probability analyses used Monte Carlo simulation and probability distributions.

Simulation refers to any analytical method meant to imitate a real­life 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 model. 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 selects variable values at random to simulate a model. When you roll a die, you

know that either a 1, 2, 3, 4, 5, or 6 will come up, but you do not know which for any particular

roll. It's 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).

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:

Probability Distribution

Figure 8B.6.3 Uniform Probability

Distribution

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 for the cell.

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 three product classes for GSFL, 4­foot medium bi­pin, 8­foot single­pin

slimline, and 8­foot recessed double contact high­output. For each of the three product classes,

DOE conducts 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 results distributions. These tables document the average LCC savings and

percentages of building analyzed with positive and negative LCC savings for various system 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 4­foot Medium Bipin

For the 4­foot medium bi­pin product class, DOE analyzed three baseline lamps: a 40W

T12, 34W T12, and 32W T8. Each lamp was analyzed at five candidate standard levels with

minimum efficacy requirement of 92.4, 85.0, 90.0, 92.3, and 95.4 lm/W. The following tables

present the LCC savings and PBP MonteCarlo results for the three 4­foot medium bipin

baselines operating in the commercial sector. Key inputs consist of using the Energy

Information Administration’s (EIA’s) Annual Energy Outlook 2007 (AEO2007) reference case

Event III:

BallastFailureEvent IV:BallastRetrofit

* Comparative lumens are sometimes non­zero 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.

8B.7.1.2 8­foot Single Pin Slimline

For the 8­foot single­pin slimline product class, DOE analyzed three baseline lamps: a 75W T12, 60W T12, and 59W T8.

Each lamp was analyzed at five candidate standard levels with minimum efficacy requirement of 87.3, 92.0, 94.8, 98.2, and 101.5

lm/W. The following tables present the LCC savings and PBP Monte Carlo results for the three 8­foot single pin slimline baselines

operating in the commercial sector. Key inputs consist of using the Energy Information Administration’s (EIA’s) Annual Energy

8B­10

EERE-2007-BT-TP-0013 COMMENT 05
Outlook 2007 (AEO2007) reference case electricity prices, and medium­range lamp and ballast prices. Note: Lamp replacement

results in Event I are not shown for a 60W T12 lamp because there are no energy saving lamp replacement options.

8B.7.1.3 8­foot Recessed Double Contact High Output

For the 8­foot recessed double contact HO, DOE analyzed two baseline lamps: a 110W T12 and 95W T12. Each lamp was

analyzed at five candidate standard levels with minimum efficacy requirement of 83.2, 86.1, 87.6, 91.9, and 95.3 lm/W. The following

tables present the LCC savings and PBP Monte Carlo results for both of the 8­foot recessed double contact high output baselines

operating in the industrial sector. Key inputs consist of using the Energy Information Administration’s (EIA’s) Annual Energy

Outlook 2007 (AEO2007) reference case electricity prices, and medium­range 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 to the analysis, DOE presents LCC and PBP results

assuming that the ballast price is equal to zero.

8B.7.2.1 4­foot Medium Bipin

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

GSFL baselines operating in the commercial sector, considering low lamp prices, high lamp

prices, or no ballast prices. Key inputs consist of using AEO2007 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.

Event

Event III:

BallastFailureEvent IV:BallastRetrofit

* Comparative lumens are sometimes non­zero 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.

8B.7.2.2 8­foot Single Pin Slimline

The following tables present the findings of an LCC analysis on the three 8­foot single pin slimline GSFL baselines operating

in the commercial sector, considering low lamp prices, high lamp prices, or no ballast prices. Key inputs consist of using AEO2007

reference case electricity prices and an analysis period of 4.0 yrs. Note: Lamp replacement results in Event I are not shown for a 60W

T12 lamp because there are no energy saving lamp replacement options.

8B.7.2.3 8­foot Recessed Double Contact HO

The following tables present the findings of an LCC analysis on the two 8­foot 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 AEO2007 reference case electricity prices and an analysis period of 3.2 yrs. 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.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

50 PAR30 lamp. For each of the three baselines, DOE conducts both probability analyses (based on Monte Carlo runs) and scenario

analyses.

8B­53

EERE-2007-BT-TP-0013 COMMENT 05
8B.8.3 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 CSL. 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 Energy Information

Administration’s (EIA’s) Annual Energy Outlook 2007 (AEO2007) reference case electricity prices and medium­range lamp prices.

8B.8.4 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 AEO2007 reference case electricity

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

residential sector.

8B.8.5 Operating Hour Scenario Results

In addition, 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 reflectors

lamps (IRL) 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 2­4 unit home) are presented. These operating hours were obtained U.S. Lighting Market Characterization: Volume Iii.

The following tables depict these results for the residential sector using key inputs such as AEO2007 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.
