APPENDIX F. MAPPING BETWEEN ENGINEERING ANALYSIS AND 

LIFE CYCLE COST ANALYSIS EFFICIENCY LEVELS 

F.1 INTRODUCTION 

This appendix provides the selection and mapping of the efficiency levels developed in 

Chapter 5, engineering analysis, and analyzed in Chapter 7, energy use characterization, to those 

eight or fewer levels identified from the engineering analysis that are used in the subsequent 

life-cycle cost (LCC) analysis, shipments analysis, and national energy savings and national net 

present value analysis. 

F.2 SELECTION OF EFFICIENCY LEVELS FOR ANALYSIS 

The U.S. Department of Energy (DOE) chose to limit the number of efficiency levels 

analyzed in the LCC and subsequent analyses to no more than eight levels per equipment class. 

In the engineering analysis, however, specific component level design options were selected one 

at a time in order of cost effectiveness to develop a manufacturer price versus energy 

consumption curve for each equipment class. The list of component level design options and the 

number of design option permutations for each equipment class determined the total number of 

efficiency levels developed in the design option portion of the engineering analysis. Between 

four and 11 efficiency levels were defined for each equipment class in the design option analysis. 

These are referred to as analytically derived efficiency levels. In addition, CRE price versus 

energy consumption data submitted by industry for four key equipment classes consisted of from 

six to 10 individual industry-supplied efficiency levels. These data are also reported in the 

engineering analysis. 

For those equipment classes for which the number of levels coming from the engineering 

analysis was less than eight, all engineering analysis levels were used. However, for equipment 

classes where more than eight efficiency levels were defined, DOE selected specific levels to 

analyze. The selection of levels was based on consideration of three basic criteria: 

1) the lowest and highest energy consumption levels provided in the engineering analysis 

were preserved 

2) if the difference in reported energy consumptions and reported manufacturer price between 

sequential levels was very small, only one level would be selected 

3) if the energy consumption savings benefit in going between levels relative to the increased 

cost was very similar across multiple sequential levels, an intermediate level might be 

removed. 

Table F.2.1 shows the efficiency levels selected from the engineering analysis to be used 

in the LCC and subsequent analyses. For each equipment class, the selected levels are 

designated as Level 1 through Level 8.
