# 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 deve loped using the LCC spreadsheet. LCC and payback periods are presented in terms of nati onal average LCC, national average LCC savings from the baseline efficiency level (Level 1) a nd 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 a nd 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-cycl e 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 th e 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 sa vings above the baseline efficien cy 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 peri od as the efficiency level changes from Level 1 (baseline) to Level 8, on a national aver aged basis weighted ove r all building types, energy prices, sales taxes, and installation costs. The maximu m 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 s hows the national distribution of payback periods calculated for all efficiency levels as well as th e average payback period a nd 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, Remo te Condenser, Low Temperature (VOP.RC.L) Figure G.2.5 shows the variation of the life-cycl e 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 re duced 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 savi ngs graphically for each efficiency level analyzed. Figure G.2.7 shows the effect on payback peri od as the efficiency level changes from Level 1 (baseline) to Level 7, on a national aver aged basis weighted ove r all building types, energy prices, sales taxes and installation cost s. 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 pe riods calculated for all efficiency levels as well as the average payback period and the percent of units with a pa yback period of less than 3 years. Figure G.2.8 shows this distribution of payback period results graphically for each efficiency level analyzed.

# G.2.2 Equipment Class: Vertical Open, Self Contained, Medium Temperature (VOP.SC.M) Figure G.2.9 shows the variation of the life-cycl e 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 efficiency levels up through Level 7 the lifetime operating cost has more of an impact on th e 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 8, which has an LCC above the baseline efficiency level. Table G.2.5 shows the national distribution of LCC sa vings above the baseline efficien cy level (Level 1) calculated for this equipment for the higher efficiency levels [2–8].

# 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 th e 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 re duced 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 (Lev el 1) for this equipment category. The minimum LCC is found at Level 6. Table G.2.7 shows th e national distribution of LCC savings above the baseline efficiency level (Level 1) calculated fo r this equipment for the higher efficiency levels [2–7]. Figure G.2.14 show this distribution of L CC 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 aver aged basis weighted ove r all building types, energy prices, sales taxes and in stallation 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 pe riods 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 re sults graphically for e ach efficiency level analyzed.

# G.2.5 Equipment Class: Vertical Closed Tr ansparent, Self Contained, Ice Cream Temperature (VCT.SC.I) Figure G.2.21 shows the variation of the life-cycle cost with th e 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 re duced 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 (Lev el 1) for this equipment category. The minimum LCC is found at Level 7. Table G.2.11 shows th e national distribution of LCC savings above the baseline efficiency level (Level 1) calculated fo r this equipment for the higher efficiency levels [2–8]. Figure G.2.22 shows 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 aver aged basis weighted ove r all building types, energy prices, sales taxes and in stallation costs. The maximum national average payback period shown for any design option for this equipment category was 1.7 years. Table G.2.12 shows the national distribution of payback pe riods 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.2.24 show this distribution of payback period re sults 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 th e 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 th e 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 high er efficiency levels, the increase in first cost offsets the energy cost savings a nd, as a result, the LCC for Level 7 exceeds that of the baseline efficiency level (Level 1). The minimum L CC 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 aver aged basis weighted ove r all building types, energy prices, sales taxes, and installation costs. The maximu m 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 le vels as well as the average payback periods and the percent of units w ith 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 th e 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 inst alled cost. In other words, the decrease in lifetime operating costs (due to re duced 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 cat egory. For efficiencies higher than Level 5, the increase in installed costs offsets the energy sa vings 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 aver aged basis weighted ove r all building types, energy prices, sales taxes, and installation costs. The maximu m 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 an d above is 19.4 years. Table G.2.20 shows the national distribution of payback pe riods 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 re sults graphically for e ach efficiency level analyzed.

# G.2.11 Equipment Class: Horizontal Open , Remote Condenser, Low Temperature (HZO.RC.L) Figure G.2.45 shows the variation of the life-cycle cost with th e 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 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 re duced 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 (Lev el 1) for this equipment category. The minimum LCC is found at efficiency Level 5. Table G.2.23 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.2.46 show this distribution of LCC sa vings graphically for each efficiency level analyzed. Figure G.2.47 shows the effect on payback period as the efficiency level changes from Level 1 (baseline) to Level 5, on a national aver aged basis weighted ove r all building types, energy prices, sales taxes, and installation costs. The maximu m national average payback period shown for any design option for this equipment category was 1.6 years. Table G.2.24 shows the national distribution of payback pe riods 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.2.48 shows this distribution of payback period re sults graphically for e ach efficiency level analyzed.

# G.3 LCC SENSITIVITY TO BASELINE LEVEL - RESULTS This section contains detailed output from th e LCC sensitivity analysis to baseline level reported in Chapter 8. These analyses were ca rried 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 cl asses 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 se nsitivity of LCC Savings and PBP to assumed baseline efficiency level, for baseline s at Level 2 through Leve l 6 respectively. The level providing maximum LCC savings is unaffected by selection of baseline efficiency level, but the magnitude of LCC savings is reduced fo r higher baseline effici ency levels. National average payback periods are shown for all effici ency levels available for each equipment class above the baseline level assumed in the sensitivity study. Other cells in the table are marked NA.
