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 (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 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 product category. Table G.2.1 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.2.2 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 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, 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 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 product category. Table G.2.3 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.2.6 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 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 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.

Figure G.2.9 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 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 product category. Table G.2.5 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.2.10 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 payback shown for any design 

option for this product category was 4.7 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.

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 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 product category. Table G.2.9 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.2.18 show 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 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 product category was 4.0 years. Table G.2.10 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.2.20 show this distribution of 

payback results graphically for each efficiency level analyzed.

G.2.7 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 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 product category. Table G.2.13 

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.2.26 show 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 payback shown for any design 

option for this product category was 1.7 years. Table G.2.14 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.2.28 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 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 product 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 averaged basis weighted over all building types, 

energy prices, sales taxes and installation costs. 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 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 product 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 averaged basis weighted over all building types, 

energy prices, sales taxes and installation costs. 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.

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 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 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 product 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 averaged basis weighted over all building types, 

energy prices, sales taxes and installation costs. 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.

Figure G.2.45 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 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 product category. Table G.2.23 

shows the national distribution of LCC savings above the baseline (Level 1) calculated for this

G.2.13 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 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 product category. Table G.2.25 

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.2.50 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 product category was 2.7 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.

Figure G.2.53 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 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 product 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 averaged basis weighted over all building types, 

energy prices, sales taxes and installation costs. 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 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 product 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 averaged basis weighted over all building types, 

energy prices, sales taxes and installation costs. 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 the Life-Cycle 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.

G.4 LCC RESULTS USING DESIGN OPTION IN PLACE OF INDUSTRY SUPPLIED 

CURVES 

Section G.4 provides LCC analysis results for 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 products. These results are presented in the same 

fashion as the results in section G.2. See Chapter 8 of the TSD for an explanation of the tables 

and figures in this appendix. 

G-82 

 EE-2006-STD-0126 COMMENT 11.2
G.4.1 Equipment Class: Vertical Open, Remote Condenser, Medium Temperature 

(VOP.RC.M) 

Figure G.4.1 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 8 (with reduced 

energy consumption). The LCC results show that at the higher efficiency levels examined 

(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 product category. However, a 

minimum LCC value is found at Level 5. It is noted that the bump up in LCC at Level 4 occurs 

at a change in lighting technology. While incremental payback was used to order the design 

options, the life of fluorescent light bulbs is shorter than that of the other efficiency measures. 

The bump up in LCC relative to the adjacent design options is due primarily to the replacement 

costs for light bulbs over the life of the equipment. 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 distribution of LCC savings graphically for each efficiency 

level analyzed. 

Figure G.4.3 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 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.

 EE-2006-STD-0126 COMMENT 11.2
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-cycle cost with the installed cost for each of 

the analytically derived efficiency levels considered for the analysis of VCT.RC.L. 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 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 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 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. 

Figure G.4.7 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 product category was 4.4 years. Table G.4.4 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.4.8 show this distribution of 

payback results 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-cycle cost with the installed cost for each of 

the analytically derived efficiency levels considered 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 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 product 

category. A minimum LCC level occurs at Level 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 distribution of LCC savings graphically 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 average basis weighted over all building types, 

energy prices, sales taxes and installation costs. 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.

G.4.13 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 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 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 product category, with the lowest 

LCC at Level 4. Table G.4.7 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.4.14 show 

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

Figure G.4.15 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 product category was 2.0 years. Table G.4.8 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.4.16 show this distribution of
