APPENDIX G. DETAILED LIFE-CYCLE COST OUTPUT 

G.1 INTRODUCTION 

Appendix G contains detailed output from the Life-Cycle 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 efficiency level (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 life-cycle 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 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 up through Level 6 is 

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

increases for Level 7, which has an LCC above the baseline efficiency level. Table G.2.1 shows 

the national distribution of LCC savings above the baseline efficiency level (Level 1) calculated 

for this equipment for the higher efficiency levels [2–8]. Figure G.2.2 shows 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 maximum national average payback period 

calculated for efficiency levels up through Level 6 is 2.1 years or less; however, the payback 

period for Level 7 is 138.1 years. Table G.2.2 shows the national distribution of payback periods 

calculated for all efficiency levels as well as the average payback period and the percent of units 

with a payback period of less than 3 years. Figure G.2.4 show this distribution of payback period 

results graphically for each efficiency level analyzed.

Equipment Class: Vertical Open, Remote Condenser, Low Temperature (VOP.RC.L) 

Figure G.2.5 shows the variation of the life-cycle 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. 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 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 efficiency level (Level 1) calculated for this equipment for the higher 

efficiency levels [2–7]. Figure G.2.6 shows 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 national average payback period 

shown for any design option for this equipment category was 2.8 years. Table G.2.4 shows the 

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

payback period and the percent of units with a payback period of less than 3 years. Figure G.2.8 

shows this distribution of payback period results graphically for each efficiency level analyzed.

G.2.3	 Equipment Class: Vertical Closed Transparent, Remote Condenser, Medium 

Temperature (VCT.RC.M) 

Figure G.2.13 shows the variation of the life-cycle 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. 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 6. Table G.2.7 shows the national distribution of LCC savings above the 

baseline efficiency level (Level 1) calculated for this equipment for the higher efficiency levels 

[2–7]. 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 national average payback period 

shown for any design option for this equipment category was 3.9 years. Table G.2.8 shows the 

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

payback period and the percent of units with a payback period of less than 3 years. Figure 

G.2.16 shows this distribution of payback period results graphically for each efficiency level 

analyzed.

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

Temperature (VCT.RC.L) 

Figure G.2.17 shows the variation of the life-cycle 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. 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 6. Table G.2.9 shows the national distribution of LCC savings above the 

baseline efficiency level (Level 1) calculated for this equipment for the higher efficiency levels 

[2–7]. Figure G.2.18 shows this distribution of LCC savings graphically for each efficiency 

level analyzed. 

Figure G.2.19 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 national average payback period 

shown for any design option for this equipment category was 2.6 years. Table G.2.10 shows the 

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

payback period and the percent of units with a payback period of less than 3 years. Figure 

G.2.20 shows this distribution of payback period results graphically for each efficiency level 

analyzed.

G.2.6	 Equipment Class: Vertical Closed Solid Door, Self Contained, Ice Cream 

Temperature (VCS.SC.I) 

Figure G.2.25 shows the variation of the life-cycle 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. 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 8. Table G.2.13 shows the national distribution of LCC savings above the 

baseline efficiency level (Level 1) calculated for this equipment for the higher efficiency levels 

[2–8]. Figure G.2.26 shows this distribution of LCC savings graphically for each efficiency 

level analyzed. 

Figure G.2.27 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 national average payback period 

shown for any design option for this equipment category was 1.3 years. Table G.2.14 shows the 

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

payback period and the percent of units with a payback period of less than 3 years. Figure 

G.2.28 shows this distribution of payback period results graphically for each efficiency level 

analyzed.

G.2.7	 Equipment Class: Semi-Vertical Open, Remote Condenser, Medium 

Temperature (SVO.RC.M) 

Figure G.2.29 shows the variation of the life-cycle 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. 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 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. However, for higher efficiency levels, the increase in first cost 

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

efficiency level (Level 1). The minimum LCC is found at Level 5. Table G.2.15 shows the 

national distribution of LCC savings above the baseline efficiency level (Level 1) calculated for 

this equipment for the higher efficiency levels [2–7]. 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 national average payback period 

calculated for efficiency levels up through Level 6 is 2.2 years or less; however, the payback 

period for Level 7 is greater than 100 years. Table G.2.16 shows the national distribution of 

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

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

distribution of payback period results graphically for each efficiency level analyzed.

G.2.9	 Equipment Class: Service Over Counter, Remote Condenser, Medium 

Temperature (SOC.RC.M) 

Figure G.2.37 shows the variation of the life-cycle 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. 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. The minimum LCC is found at Level 5. Table G.2.19 shows the national 

distribution of LCC savings above the baseline efficiency level (Level 1) calculated for this 

equipment for the higher efficiency levels [2–7]. 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 national average payback period 

calculated for efficiency levels up through Level 5 is 1.7 years or less; however, the maximum 

national-average payback period for Levels 6 and above is 19.4 years. Table G.2.20 shows the 

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

payback period and the percent of units with a payback period of less than 3 years. Figure 

G.2.40 shows this distribution of payback period results graphically for each efficiency level 

analyzed.

G.2.10	 Equipment Class: Horizontal Open, Remote Condenser, Medium Temperature 

(HZO.RC.M) 

Figure G.2.41 shows the variation of the life-cycle 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 efficiency level (Level 1) calculated for this equipment for the higher efficiency levels 

[2-5]. 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 national average payback period 

shown for any design option for this equipment category was 1.6 years. Table G.2.21 shows the 

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

payback period and the percent of units with a payback period of less than 3 years. Figure 

G.2.44 shows this distribution of payback period results graphically for each efficiency level 

analyzed.

G.2.12	 Equipment Class: Horizontal Open, Self Contained, Medium Temperature 

(HZO.SC.M) 

Figure G.2.49 shows the variation of the life-cycle 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. 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 efficiency level (Level 1) calculated for this equipment for the higher efficiency levels 

[2–8]. Figure G.2.50 shows 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 national average payback period 

shown for any design option for this equipment category was 2.3 years. Table G.2.26 shows the 

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

payback period and the percent of units with a payback period of less than 3 years. Figure 

G.2.52 shows this distribution of payback period results graphically for each efficiency level 

analyzed.

energy prices, sales taxes, and installation costs. The maximum national average payback period 

shown for any design option for this equipment category was 1.7 years. Table G.2.28 shows the 

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

payback period and the percent of units with a payback period of less than 3 years. Figure 

G.2.56 shows this distribution of payback period results graphically for each efficiency level 

analyzed.

G.2.14	 Equipment Class: Horizontal Closed Transparent, Self Contained, Ice-Cream 

Temperature (HCT.SC.I) 

Figure G.2.57 shows the variation of the life-cycle 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. 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 efficiency level (Level 1) calculated for this equipment for the higher efficiency levels 

[2–6]. Figure G.2.58 shows 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 national-average payback period 

shown for any design option for this equipment category was 1.9 years. Table G.2.30 shows the 

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

payback period and the percent of units with a payback period of less than 3 years. Figure 

G.2.60 shows this distribution of payback period results graphically for each efficiency level 

analyzed.

G.3 LCC SENSITIVITY TO BASELINE LEVEL - RESULTS 

This section contains detailed output from the 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 

payback period (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 PBP 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 baseline efficiency levels. 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.
