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 lifecycle­cost analysis, shipments analysis, and national energy savings and national net present

value analysis.

F.2 SELECTION OF EFFICIENCY LEVELS FOR ANALYSIS

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 cost­effectiveness

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 eleven 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 ten 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.
