### APPENDIX 8B. DETAILED LIFE - CYCLE COST AND PAYBACK PERIOD ANALYSIS RESULTS 8B.1 INTRODUCTION This appendix contains detailed output from the l ife -c ycle c ost (LCC) and payback period (PBP) a nalysis for automatic c ommercial ice makers, as developed using the LCC spreadsheet. LCC and PBPs are presented for each of the 2 1 1 

### 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 th is 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 25 th and 75 th 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). T o simplify the presentation, all efficiency levels are presented as numbered levels. Hence, the efficiency level called b ase line in other chapters of this TSD is presented as Level 1. All higher efficiency levels are numbered sequentially, from Level 1 to L evel 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.
