APPENDIX 10-B. NATIONAL ENERGY SAVINGS AND NET PRESENT VALUE USING 

ECONOMIC GROWTH SCENARIOS

10-B.1 INTRODUCTION

This appendix presents national energy savings (NES) and net present value (NPV) 

results for alternative economic scenarios for room air conditioners and clothes dryers. DOE 

explained the calculations of NES and NPV using the reference installation costs and the default 

energy price forecast in chapter 10, National Impact Analysis.

10-B.2 ROOM AIR CONDITIONER RESULTS USING ECONOMIC GROWTH 

SCENARIOS

For each room air conditioner product class, DOE calculated NES and NPV using energy 

price scenarios from the High and Low Economic Growth cases. The NES results are the same 

in each energy price scenario. As one would expect, the NPV is most favorable using prices in 

the High Growth scenario, and least favorable using prices in the Low Growth scenario.
