APPENDIX 8-G. REBUTTABLE PAYBACK ANALYSIS RESULTS

8-G.1 INTRODUCTION

 This appendix contains the cost and efficiency result tables described in chapter 8. 

DOE based the payback periods on the calculation methodology found in the DOE room 

air conditioner and clothes dryer test procedures; these payback period results may differ 

from those determined under field conditions. 

8-G.2 ENERGY CALCULATIONS

8-G.1.1 Clothes Dryers

 The energy consumption in the LCC analysis is determined using the DOE test 

procedure. The DOE test procedure calculates annual energy consumption, Eannual, as 

follows: 

E Cycles CEFLbs )/( F ×=

Where:

Cycles = clothes dryer cycles per year, cycles/yr, (416 cycles/yr), 

Lbs = pounds of clothing, lbs, (7 lbs for standard and 3 lbs. for compact 

dryer) and

CEF = clothes dryer efficiency.

8-G.1.2 Room Air Conditioners

 The energy consumption in the LCC analysis is determined using the DOE test 

procedure. The DOE test procedure calculates annual energy consumption, Eannual, as 

follows: 

Eannual = Capacity × Hrs /)1000/( CEER

Where:

Capacity = room air conditioner input capacity, 

Hrs = room air conditioner operating hours (750 hrs), and 

CEER = room air conditioner efficiency.

8-G.3 RESULTS TABLES

Tables 8-G.3.1 to 8-G.3.10 show the rebuttable payback period results for each 

product class.
