## APPENDIX G. DETAILED LIFE­CYCLE COST OUTPUT

G.1 INTRODUCTION

Appendix G contains detailed output from the Life­Cycle Cost (LCC) Analysis for

Commercial Refrigeration Equipment as developed using the LCC spreadsheet. LCC and

payback periods are presented in terms of national average LCC, national average LCC savings

from the baseline (Level 1) and national average payback period results for each of the

15 equipment classes at each efficiency level. See Chapter 8 of the TSD for an explanation of

the tables and figures in this appendix.

G.2 LCC RESULTS

G.2.1 Equipment Class: Vertical Open, Remote Condenser, Medium Temperature

(VOP.RC.M)

Figure G.2.1 shows the variation of the life­cycle cost with the installed cost for each of

the efficiency levels considered for the analysis. The installed cost is the sum of the equipment

price and the installation cost of the equipment and the former is the largest contributor to the

increasing total installed cost as the efficiency level rises from Level 1 to Level 7 (with reduced

energy consumption). The LCC results show that at efficiency levels up through Level 5 the

lifetime operating cost has more of an impact on the LCC than the total installed cost. In other

words, the decrease in lifetime operating costs (due to reduced electricity costs) offsets the

increase in total installed cost. As a result, the LCC at all efficiency levels up through Level 5 is

lower than that for the baseline efficiency level (Level 1) for this equipment category. The LCC

increases for higher efficiency levels, although only Level 7 has an LCC above the baseline

level. Table G.2.1 shows the national distribution of LCC savings above the baseline (Level 1)

calculated for this equipment for the higher efficiency levels [2­8]. Figure G.2.2 show this

distribution of LCC savings graphically for each efficiency level analyzed.

Figure G.2.3 shows the effect on payback period as the efficiency level changes from

Level 1 (baseline) to Level 8, on a national averaged basis weighted over all building types,

energy prices, sales taxes and installation costs. The average payback calculated for efficiency

levels up through Level 6 is 2.4 years or less, however the payback period for Level 7 is 9.7

years. Table G.2.2 shows the national distribution of payback periods calculated for all

efficiency levels as well as the average payback and the percent of units with a payback of less

than 3 years. Figure G.2.4 show this distribution of payback results graphically for each

efficiency level analyzed.

## G.2.2 Equipment Class: Vertical Open, Remote Condenser, Low Temperature

(VOP.RC.L)

Figure G.2.5 shows the variation of the life­cycle cost with the installed cost for each of

the efficiency levels considered for the analysis. The installed cost is the sum of the equipment

price and the installation cost of the equipment and the former is the largest contributor to the

increasing total installed cost as the efficiency level rises from Level 1 to Level 6 (with reduced

energy consumption). The LCC results show that for efficiency levels from Level 2 through

Level 7, the lifetime operating cost has more of an impact on the LCC than the total installed

cost. In other words, the decrease in lifetime operating costs (due to reduced electricity costs)

offsets the increase in total installed cost. As a result, the LCC at all efficiency levels is lower

than that for the baseline efficiency level (Level 1) for this equipment category. However, the

minimum LCC is found at Level 6. Table G.2.3 shows the national distribution of LCC savings

above the baseline (Level 1) calculated for this equipment for the higher efficiency levels [2­7].

Figure G.2.6 show this distribution of LCC savings graphically for each efficiency level

analyzed.

Figure G.2.7 shows the effect on payback period as the efficiency level changes from

Level 1 (baseline) to Level 7, on a national averaged basis weighted over all building types,

energy prices, sales taxes and installation costs. The maximum payback shown for any design

option for this equipment category was 3.0 years. Table G.2.4 shows the national distribution of

payback periods calculated for all efficiency levels as well as the average payback and the

percent of units with a payback of less than 3 years. Figure G.2.8 show this distribution of

payback results graphically for each efficiency level analyzed.

## G.2.3 Equipment Class: Vertical Open, Self Contained, Medium Temperature

(VOP.SC.M)

Figure G.2.9 shows the variation of the life­cycle cost with the installed cost for each of

the efficiency levels considered for the analysis. The installed cost is the sum of the equipment

price and the installation cost of the equipment and the former is the largest contributor to the

increasing total installed cost as the efficiency level rises from Level 1 to Level 8 (with reduced

energy consumption). The LCC results show that at the higher efficiency levels (Level 2

­

Level 8), the lifetime operating cost has more of an impact on the LCC than the total installed

cost. In other words, the decrease in lifetime operating costs (due to reduced electricity costs)

offsets the increase in total installed cost. As a result, the LCC at all efficiency levels is lower

than that for the baseline efficiency level (Level 1) for this equipment category. The minimum

LCC is found at Level 6. Table G.2.5 shows the national distribution of LCC savings above the

baseline (Level 1) calculated for this equipment for the higher efficiency levels [2­8]. Figure

G.2.10 show this distribution of LCC savings graphically for each efficiency level analyzed.

Figure G.2.11 shows the effect on payback period as the efficiency level changes from

Level 1 (baseline) to Level 8, on a national averaged basis weighted over all building types,

energy prices, sales taxes and installation costs. The maximum national­average payback shown

for any design option for this equipment category was 5.9 years. Table G.2.6 shows the national

distribution of payback periods calculated for all efficiency levels as well as the average payback

and the percent of units with a payback of less than 3 years. Figure G.2.12 show this distribution

of payback results graphically for each efficiency level analyzed.

## G.2.4 Equipment Class: Vertical Closed Transparent, Remote Condenser, Medium

Temperature (VCT.RC.M)

Figure G.2.13 shows the variation of the life­cycle cost with the installed cost for each of

the efficiency levels considered for the analysis. The installed cost is the sum of the equipment

price and the installation cost of the equipment and the former is the largest contributor to the

increasing total installed cost as the efficiency level rises from Level 1 to Level 7 (with reduced

energy consumption). The LCC results show that at the higher efficiency levels (Level 2

­

Level 7), the lifetime operating cost has more of an impact on the LCC than the total installed

cost. In other words, the decrease in lifetime operating costs (due to reduced electricity costs)

offsets the increase in total installed cost. As a result, the LCC at all efficiency levels is lower

than that for the baseline efficiency level (Level 1) for this equipment category. The minimum

LCC is found at Level 5. Table G.2.7 shows the national distribution of LCC savings above the

baseline (Level 1) calculated for this equipment for the higher efficiency levels [2­7]. Figure

G.2.14 show this distribution of LCC savings graphically for each efficiency level analyzed.

Figure G.2.15 shows the effect on payback period as the efficiency level changes from

Level 1 (baseline) to Level 7, on a national averaged basis weighted over all building types,

energy prices, sales taxes and installation costs. The maximum national­average payback shown

for any design option for this equipment category was 6.1 years. Table G.2.8 shows the national

distribution of payback periods calculated for all efficiency levels as well as the average payback

and the percent of units with a payback of less than 3 years. Figure G.2.16 show this distribution

of payback results graphically for each efficiency level analyzed.

## G.2.6 Equipment Class: Vertical Closed Transparent, Self Contained, Ice Cream

Temperature (VCT.SC.I)

Figure G.2.21 shows the variation of the life­cycle cost with the installed cost for each of

the efficiency levels considered for the analysis. The installed cost is the sum of the equipment

price and the installation cost of the equipment and the former is the largest contributor to the

increasing total installed cost as the efficiency level rises from Level 1 to Level 8 (with reduced

energy consumption). The LCC results show that at the higher efficiency levels (Level 2

­

Level 8), the lifetime operating cost has more of an impact on the LCC than the total installed

cost. In other words, the decrease in lifetime operating costs (due to reduced electricity costs)

offsets the increase in total installed cost. As a result, the LCC at all efficiency levels is lower

than that for the baseline efficiency level (Level 1) for this equipment category. The minimum

LCC is found at Level 7. Table G.2.11 shows the national distribution of LCC savings above the

baseline (Level 1) calculated for this equipment for the higher efficiency levels [2­8]. Figure

G.2.22 show this distribution of LCC savings graphically for each efficiency level analyzed.

Figure G.2.23 shows the effect on payback period as the efficiency level changes from

Level 1 (baseline) to Level 8, on a national averaged basis weighted over all building types,

energy prices, sales taxes and installation costs. The maximum national­average payback shown

for any design option for this equipment category was 2.5 years. Table G.2.12 shows the

national distribution of payback periods calculated for all efficiency levels as well as the average

payback and the percent of units with a payback of less than 3 years. Figure G.2.24 show this

distribution of payback results graphically for each efficiency level analyzed.

## G.2.8 Equipment Class: Semi­Vertical Open, Remote Condenser, Medium

Temperature (SVO.RC.M)

Figure G.2.29 shows the variation of the life­cycle cost with the installed cost for each of

the efficiency levels considered for the analysis. The installed cost is the sum of the equipment

price and the installation cost of the equipment and the former is the largest contributor to the

increasing total installed cost as the efficiency level rises from Level 1 to Level 7 (with reduced

energy consumption). The LCC results show that for all efficiency levels up to Level 5 the

lifetime operating cost has more of an impact on the LCC than the total installed cost. In other

words, the decrease in lifetime operating costs (due to reduced electricity costs) offsets the

increase in total installed cost. However, for higher efficiency levels, the increase in first cost

offsets the energy cost savings and as a result, the LCC for Level 6 and Level 7 exceeds that of

the that of the baseline efficiency level (Level 1). Table G.2.15 shows the national distribution

of LCC savings above the baseline (Level 1) calculated for this equipment for the higher

efficiency levels [2­7]. Figure G.2.30 show this distribution of LCC savings graphically for each

efficiency level analyzed.

Figure G.2.31 shows the effect on payback period as the efficiency level changes from

Level 1 (baseline) to Level 7, on a national averaged basis weighted over all building types,

energy prices, sales taxes and installation costs. The maximum national­average payback shown

for any design option for this equipment category was 9.7 years. Table G.2.16 shows the

national distribution of payback periods calculated for all efficiency levels as well as the average

payback and the percent of units with a payback of less than 3 years. Figure G.2.32 show this

distribution of payback results graphically for each efficiency level analyzed.

(SVO.SC.M)

Figure G.2.33 shows the variation of the life­cycle cost with the installed cost for each of

the efficiency levels considered for the analysis. The installed cost is the sum of the equipment

price and the installation cost of the equipment and the former is the largest contributor to the

increasing total installed cost as the efficiency level rises from Level 1 to Level 8 (with reduced

energy consumption). The LCC results show that at the higher efficiency levels (Level 2

­

Level 8), the lifetime operating cost has more of an impact on the LCC than the total installed

cost. In other words, the decrease in lifetime operating costs (due to reduced electricity costs)

offsets the increase in total installed cost. As a result, the LCC at all efficiency levels is lower

than that for the baseline efficiency level (Level 1) for this equipment category. The minimum

LCC point is Level 6. Table G.2.17 shows the national distribution of LCC savings above the

baseline (Level 1) calculated for this equipment for the higher efficiency levels [2­8]. Figure

G.2.34 show this distribution of LCC savings graphically for each efficiency level analyzed.

Figure G.2.35 shows the effect on payback period as the efficiency level changes from

Level 1 (baseline) to Level 8, on a national averaged basis weighted over all building types,

energy prices, sales taxes and installation costs. The maximum national­average payback shown

for any design option for this equipment category was 5.9 years. Table G.2.18 shows the

national distribution of payback periods calculated for all efficiency levels as well as the average

payback and the percent of units with a payback of less than 3 years. Figure G.2.36 show this

distribution of payback results graphically for each efficiency level analyzed.

## G.2.10 Equipment Class: Service Over Counter, Remote Condenser, Medium

Temperature (SOC.RC.M)

Figure G.2.37 shows the variation of the life­cycle cost with the installed cost for each of

the efficiency levels considered for the analysis. The installed cost is the sum of the equipment

price and the installation cost of the equipment and the former is the largest contributor to the

increasing total installed cost as the efficiency level rises from Level 1 to Level 8 (with reduced

energy consumption). The LCC results show that up to Level 5, the lifetime operating cost has

more of an impact on the LCC than the total installed cost. In other words, the decrease in

lifetime operating costs (due to reduced electricity costs) offsets the increase in total installed

cost. As a result, the LCC at all efficiency levels up to Level 5 is lower than that for the baseline

efficiency level (Level 1) for this equipment category. For efficiencies higher than Level 5, the

increase in installed costs offsets the energy savings and the LCC is higher than that for the

baseline level. Table G.2.19 shows the national distribution of LCC savings above the baseline

(Level 1) calculated for this equipment for the higher efficiency levels [2­7]. Figure G.2.38

show this distribution of LCC savings graphically for each efficiency level analyzed.

Figure G.2.39 shows the effect on payback period as the efficiency level changes from

Level 1 (baseline) to Level 8, on a national averaged basis weighted over all building types,

energy prices, sales taxes and installation costs. The maximum national­average payback shown

for any design option for this equipment category was 12.6 years. Table G.2.20 shows the

national distribution of payback periods calculated for all efficiency levels as well as the average

payback and the percent of units with a payback of less than 3 years. Figure G.2.40 show this

## G.2.11 Equipment Class: Horizontal Open, Remote Condenser, Medium Temperature

(HZO.RC.M)

Figure G.2.41 shows the variation of the life­cycle cost with the installed cost for each of

the efficiency levels considered for the analysis. The installed cost is the sum of the equipment

price and the installation cost of the equipment and the former is the largest contributor to the

increasing total installed cost as the efficiency level rises from Level 1 to Level 5 (with reduced

energy consumption). The LCC results show that at the higher efficiency levels (Level 2

­

Level 5), the lifetime operating cost has more of an impact on the LCC than the total installed

cost. In other words, the decrease in lifetime operating costs (due to reduced electricity costs)

offsets the increase in total installed cost. As a result, the LCC at all efficiency levels is lower

than that for the baseline efficiency level (Level 1) for this equipment category. The minimum

LCC is found at Level 4. Table G.2.21 shows the national distribution of LCC savings above the

baseline (Level 1) calculated for this equipment for the higher efficiency levels [2­5]. Figure

G.2.42 show this distribution of LCC savings graphically for each efficiency level analyzed.

Figure G.2.43 shows the effect on payback period as the efficiency level changes from

Level 1 (baseline) to Level 4, on a national averaged basis weighted over all building types,

energy prices, sales taxes and installation costs. The maximum payback shown for any design

option for this equipment category was 1.8 years. Table G.2.21 shows the national distribution

of payback periods calculated for all efficiency levels as well as the average payback and the

percent of units with a payback of less than 3 years. Figure G.2.44 show this distribution of

payback results graphically for each efficiency level analyzed.

## G.2.13 Equipment Class: Horizontal Open, Self Contained, Medium Temperature

(HZO.SC.M)

Figure G.2.49 shows the variation of the life­cycle cost with the installed cost for each of

the efficiency levels considered for the analysis. The installed cost is the sum of the equipment

price and the installation cost of the equipment and the former is the largest contributor to the

increasing total installed cost as the efficiency level rises from Level 1 to Level 8 (with reduced

energy consumption). The LCC results show that at the higher efficiency levels (Level 2

­

Level 8), the lifetime operating cost has more of an impact on the LCC than the total installed

cost. In other words, the decrease in lifetime operating costs (due to reduced electricity costs)

offsets the increase in total installed cost. As a result, the LCC at all efficiency levels is lower

than that for the baseline efficiency level (Level 1) for this equipment category. The minimum

LCC is found at Level 7. Table G.2.25 shows the national distribution of LCC savings above the

baseline (Level 1) calculated for this equipment for the higher efficiency levels [2­8]. Figure

G.2.50 show this distribution of LCC savings graphically for each efficiency level analyzed.

Figure G.2.51 shows the effect on payback period as the efficiency level changes from

Level 1 (baseline) to Level 8, on a national averaged basis weighted over all building types,

energy prices, sales taxes and installation costs. The maximum payback shown for any design

option for this equipment category was 2.5 years. Table G.2.26 shows the national distribution

of payback periods calculated for all efficiency levels as well as the average payback and the

percent of units with a payback of less than 3 years. Figure G.2.52 show this distribution of

payback results graphically for each efficiency level analyzed.

## G.2.15 Equipment Class: Horizontal Closed Transparent, Self Contained, Ice­Cream

Temperature (HCT.SC.I)

Figure G.2.57 shows the variation of the life­cycle cost with the installed cost for each of

the efficiency levels considered for the analysis. The installed cost is the sum of the equipment

price and the installation cost of the equipment and the former is the largest contributor to the

increasing total installed cost as the efficiency level rises from Level 1 to Level 6 (with reduced

energy consumption). The LCC results show that at the higher efficiency levels (Level 2

­

Level 6), the lifetime operating cost has more of an impact on the LCC than the total installed

cost. In other words, the decrease in lifetime operating costs (due to reduced electricity costs)

offsets the increase in total installed cost. As a result, the LCC at all efficiency levels is lower

than that for the baseline efficiency level (Level 1) for this equipment category. The minimum

LCC is found at Level 5. Table G.2.29 shows the national distribution of LCC savings above the

baseline (Level 1) calculated for this equipment for the higher efficiency levels [2­6]. Figure

G.2.58 show this distribution of LCC savings graphically for each efficiency level analyzed.

Figure G.2.59 shows the effect on payback period as the efficiency level changes from

Level 1 (baseline) to Level 6, on a national averaged basis weighted over all building types,

energy prices, sales taxes and installation costs. The maximum payback shown for any design

option for this equipment category was 2.1 years. Table G.2.30 shows the national distribution

of payback periods calculated for all efficiency levels as well as the average payback and the

percent of units with a payback of less than 3 years. Figure G.2.60 show this distribution of

payback results graphically for each efficiency level analyzed.

## G.3 LCC SENSITIVITY TO BASELINE LEVEL ­ RESULTS

This section contains detailed output from the Life­Cycle Cost (LCC) sensitivity analysis

to baseline level reported in Chapter 8. These analyses were carried out using the LCC

spreadsheet with the aggregated results reported in terms of national average LCC savings or

national average PBP for each of the 15 equipment classes at each efficiency level. See Chapter

8 for a further explanation of the sensitivity analysis and results.

Table G.3.1 through Table G.3.5 show the sensitivity of LCC Savings and Payback

Period to assumed baseline efficiency level, for baselines at Level 2 through Level 6

respectively. The level providing maximum LCC savings is unaffected by selection of baseline

efficiency level, but the magnitude of LCC savings is reduced for higher efficiency baselines.

National average payback periods are shown for all efficiency levels available for each

equipment class above the baseline level assumed in the sensitivity study. Other cells in the

table are marked NA.
