# APPENDIX F. MAPPING BETWEEN ENGINEERING ANALYSIS AND

LIFE CYCLE COST ANALY SIS EFFICIENCY LEVELS

F.1 INTRODUCTION

This appendix provides the selection and mappi ng 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 engineer ing analysis that are used in the subsequent

life-cycle cost (LCC) analysis, shipments analys is, 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 co mponent 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. Th e 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 eac h equipment class in the design option analysis.

These are referred to as analytic ally 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-suppl ied 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 analys is 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 base d on consideration of three basic criteria:

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

were preserved

2) if the difference in reported energy consump tions 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 sequentia l 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.
