## 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 (Level 1) and national av erage 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, Remo te 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 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 decrea se 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 product cate gory. Table G.2.1 shows the national distribution of LCC sa vings above the baseline (Level 1) calculated for this product for the higher efficiency levels [2-8]. Figur e G.2.2 show 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 cost s. The maximum payback shown for any design option for this product category was 4.7 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, Re mote 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 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 decrea se 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 product cate gory. Table G.2.3 shows the national distribution of LCC sa vings above the baseline (Level 1) calculated for this product for the higher efficiency levels [2-6]. Figur e G.2.6 show this distribution of LCC savings 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 6, on a national aver aged basis weighted ove r all building types, energy prices, sales taxes and installation cost s. The maximum payback shown for any design option for this product 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.2.4 Equipment Class: Vertical Closed Tr ansparent, 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 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 decrea se 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 product cate gory. Table G.2.7 shows the national distribution of LCC sa vings above the baseline (Level 1) calculated for this product for the higher efficiency levels [2-7]. Figur e G.2.14 show this distri bution 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 aver aged basis weighted ove r all building types, energy prices, sales taxes and installation cost s. The maximum payback shown for any design option for this product category was 6.0 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.

## G.2.6 Equipment Class: Vertical Closed Tran sparent, 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 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 decrea se 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 (L evel 1) for this produc t category. Table G.2.11 shows the national distribution of LCC savings above the baseline (Level 1) calculated for this product for the higher efficiency levels [2-8]. 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 aver aged basis weighted ove r all building types, energy prices, sales taxes and installation cost s. The maximum payback shown for any design option for this product category was 3.1 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: 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 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 decrea se 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 (L evel 1) for this produc t category. Table G.2.15 shows the national distribution of LCC savings above the baseline (Level 1) calculated for this product 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 cost s. The maximum payback shown for any design option for this product category was 4.5 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.

## G.2.10 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 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 decrea se 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 (L evel 1) for this produc t category. Table G.2.19 shows the national distribution of LCC savings above the baseline (Level 1) calculated for this product 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 7, on a national aver aged basis weighted ove r all building types, energy prices, sales taxes and installation cost s. The maximum payback shown for any design option for this product category was 6.0 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 distribution of payback results graphically for each efficiency level analyzed.

## G.2.11 Equipment Class: Horizontal Open, Remote Condenser, Medium Temperature (HZO.RC.M) Figure G.2.41 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 and the former is the largest contributor to the increasing total installed cost as the efficiency level rises from Level 1 to Level 4 (with reduced energy consumption). The LCC results show that at the higher efficiency levels (Level 2 - Level 4), the lifetime operating cost has more of an impact on the LCC than the total installed cost. In other words, the decrea se 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 (L evel 1) for this produc t category. Table G.2.21 shows the national distribution of LCC savings above the baseline (Level 1) calculated for this product for the higher efficiency levels [2-4]. 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 aver aged basis weighted ove r all building types, energy prices, sales taxes and installation cost s. The maximum payback shown for any design option for this product category was 2.2 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.2.14 Equipment Class: Horizontal Open, Self Contained, Low Temperature (HZO.SC.L) Figure G.2.53 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 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 decrea se 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 (L evel 1) for this produc t category. Table G.2.27 shows the national distribution of LCC savings above the baseline (Level 1) calculated for this product for the higher efficiency levels [2-8]. Figure G.2.54 show this distribution of LCC savings graphically for each efficiency level analyzed. Figure G.2.55 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 cost s. The maximum payback shown for any design option for this product category was 2.0 years. Table G.2.28 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.2.56 show this distribution of payback results graphically for each efficiency level analyzed.

## G.2.15 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 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 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 decrea se 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 (L evel 1) for this produc t category. Table G.2.29 shows the national distribution of LCC savings above the baseline (Level 1) calculated for this product for the higher efficiency levels [2-6]. 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 aver aged basis weighted ove r all building types, energy prices, sales taxes and installation cost s. The maximum payback shown for any design option for this product 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 th e Life-Cycle Cost (LCC) sensitivity analysis to baseline level reported in chapter 8. Thes e analyses were carried out using the LCC spreadsheet with the aggregated results reporte d in terms of national average LCC savings or national average 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 Payback Period to assumed baseline efficiency level, for baselines at Level 2 through Level 6 respectively. The level providing maximum LCC sa vings is unaffected by selection of baseline efficiency level, but the magnit ude of LCC savings is reduced fo r 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.

## G.4 LCC RESULTS USING DESIGN OPTION IN PLACE OF INDUSTRY SUPPLIED CURVES Section G.4 provides LCC analysis results fo r four classes of commercial refrigeration equipment (VOP.RC.M, VCT.RC.L, SVO.RC.M , and HZO.RC.L) developed using the DOE analytically derived curves for each of these prod ucts. These results are presented in the same fashion as the results in section G.2. See Chapter 8 of the TSD fo r an explanation of the tables and figures in this appendix.

## G.4.1 Equipment Class: Vertical Open, Remo te Condenser, Medium Temperature (VOP.RC.M) Figure G.4.1 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 8 (with reduced energy consumption). The LCC results show that at the higher efficiency levels examined (Level 2 - Level 6), the lifetime operating cost ha s more of an impact on the LCC than the total installed cost. In other words, the decrease in lifetime operating co sts (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 produ ct category. However, a minimum LCC value is found at Level 5. It is no ted that the bump up in LCC at Level 4 occurs at a change in lighting technology. While incr emental payback was used to order the design options, the life of fluorescent light bulbs is shorte r than that of the othe r efficiency measures. The bump up in LCC relative to the adjacent desi gn options is due primarily to the replacement costs for light bulbs over the life of the equipm ent. Table G.4.1 shows the national distribution of LCC savings above the baseline (Level 1) calculated for this product for the higher efficiency levels [2-6]. Figure G.4.2 show this distributi on of LCC savings graphica lly for each efficiency level analyzed. Figure G.4.3 shows the effect on payback peri od as the efficiency level changes from Level 1 (baseline) to Level 6, on a national aver aged basis weighted ove r all building types, energy prices, sales taxes and installation cost s. The maximum payback shown for any design option for this product category was 7.5 years. Table G.4.2 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.4.4 show this distribution of payback results graphically for each efficiency level analyzed.

## G.4.2 Equipment Class: Vertical Closed Transparent, Remote Condenser, Low Temperature (VCT.RC.L) Figure G.4.5 shows the variation of the life-cycl e cost with the installed cost for each of the analytically derived efficiency levels consid ered for the analysis of VCT.RC.L. The installed cost is the sum of the equipment price and the inst allation cost of the equipment and the former is the largest contributor to the increasing total inst alled cost as the efficiency level rises from Level 1 to Level 7 (with reduced energy consumption). The LCC results show that at each subsequent higher efficiency levels (Level 2 - Level 7), the lifetime operating cost has more of an impact on the LCC than the total installed co st. 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 lowe r than that for the baseline efficiency level (Level 1) for this product category. However, a minimum LCC is found at Level 6, with Level Level 7 showing slightly higher LCC values than Level 6. Table G.4.3 shows the national distribution of LCC savings above the baseline (Level 1) calculated for this product for the higher efficiency levels [2-7]. Figure G.4.6 show this distribution of LCC savings graphically for each efficiency level analyzed.

## G.4.3 Equipment Class: Semi-Vertical Open , Remote Condenser, Medium Temperature (SVO.RC.M) Figure G.4.9 shows the variation of the life-cycl e cost with the installed cost for each of the analytically derived efficiency levels c onsidered for the analysis of SVO.RC.M. 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 co nsumption). 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 wo rds, the decrease in lifetime operating costs (due to reduced electricity costs) offset s the increase in total installed cost. As a result, the LCC at all efficiency levels is lower than that for the base line efficiency level (L evel 1) for this product category. A minimum LCC level occurs at Leve l 5. Table G.4.5 shows the national distribution of LCC savings above the baseline (Level 1) calculated for this product for the higher efficiency levels [2-6]. Figure G.4.10 show this distributi on of LCC savings graphica lly for each efficiency level analyzed. Figure G.4.11 shows the effect on payback period as the efficiency level changes from Level 1 (baseline) to Level 6, on a national av erage basis weighted ove r all building types, energy prices, sales taxes and installation cost s. The maximum payback shown for any design option for this product category was 7.2 years. Table G.4.6 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.4.12 show this distribution of payback results graphically for each efficiency level analyzed.
