### APPENDIX 8

- G. REBUTTABLE PAYBACK A NALYSIS RESULTS

8- G.1 INTRODUCTION

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

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

air conditioner and clothes dryer test procedure s; 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, E annual 

### , as

follows:



## )/( CEFLbs Cycles E

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

C

EF = 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, E annual 

### , as

follows:



### CEER Hrs Capacity E

annual 

### /)1000/( **× =** 

Where:

Capacity = room air conditioner input capacity,

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

CEER = room air conditioner efficiency.8
