APPENDIX 8B. DETAILED LIFE-CYCLE COST AND PAYBACK PERIOD 

ANALYSIS RESULTS

8B.1 INTRODUCTION

This appendix contains detailed output from the life-cycle cost (LCC) and payback period 

(PBP) analysis for automatic commercial ice makers, as developed using the LCC spreadsheet. 

LCC and PBPs are presented for each of the 211 equipment classes at each efficiency level. See 

chapter 8 of the technical support document (TSD) for an explanation of the LCC spreadsheet. 

LCC savings output obtained from the LCC analysis are in the form of distributions. LCC 

savings distributions were generated by performing 10,000 separate simulations using the LCC 

spreadsheet, and allowing the spreadsheet to select values for numerous inputs given probability 

distributions for each input. Given the results of the LCC model simulations, for each equipment 

type, the U.S. Department of Energy (DOE) calculated summary statistics—average values for 

LCC, product installation costs and operating costs; a distribution of customers who: (1) receive 

benefits in the form of lower LCC results; (2) are not affected by the standards; or (3) experience 

a cost in the form of increased LCC from equipment ownership. Results of the LCC and 

accompanying PBP analyses are shown in the tables in this appendix. 

Also included in this appendix are two graphical presentations for each of the LCC and 

PBP results. One plots LCC savings distribution for all equipment classes analyzed. The figures 

illustrate the mean and median values on the plot with the help of red and blue markers, 

respectively. Additionally, the mean and median values are surrounded by rectangular boxes 

used to represent the 25th and 75th percentile values. The lower edge of the elongated rectangle 

represents 25th percentile, which means that 25 percent of the customers will experience LCC 

savings below the value represented by the bottom of the rectangle if the standard were set at 

level in question. The upper edge of the elongated rectangle represents the 75th percentile. 

Finally, each of the rectangles includes two “tails,” or two vertical black lines, extending 

downward to represent the 5th percentile (lower end) and upward to represent the 95th percentile 

(upper end). 

To simplify the presentation, all efficiency levels are presented as numbered levels. 

Hence, the efficiency level called baseline in other chapters of this TSD is presented as Level 1. 

All higher efficiency levels are numbered sequentially, from Level 1 to Level 7. 

The remainder of this appendix presents the tabular and graphical results for the 21 

equipment classes analyzed for the automatic commercial ice maker rulemaking. 

 

1 One class, self-contained, water cooled, small continuous units have no shipments. Thus, they have not been 

defined in the analyses and are not shown herein.
