Association of Home Appliance Manufacturers (AHAM) DOE Workshop on Potential Revisions to the Energy Star Criteria for Dishwashers

July 13, 2005

Larry Wethje, AHAM


Introduction

Introduction

  • AHAM

    • Manufacturers’ Trade Association

    • Members represent manufacturers of >90% of dishwashers sold in the U.S.A.

  • Focus of AHAM Comments to DOE

    • Standby Power

    • Water Usage

    • Effective Date


Standby power

Standby Power

  • Should it be incorporated?

  • Minimal impact: 1 watt < $1/yr

  • AHAM Recommendations:

    • IF it is included, do not set prescriptive limit such as “x” watts for standby power

    • Consider maximum allowable energy usage in kWh/yr, which would include normal energy usage (EF) AND standby power

    • Benefit: give manufacturers more flexibility to innovate and manage energy (e.g., reduce peak loads)


Water usage

Water Usage

  • AHAM Recommendations:

    • Do not set prescriptive limit on water use; not necessary

    • Higher energy efficiency is directly linked to less water usage (as shown on next slide)

    • Focus on reducing consumer pre-rinsing instead

Effective date

Effective Date

  • Consider sufficient time so manufacturers can revise complete product lines and strategies

  • Set effective date that is at least 24 months past the date on which the criteria is finalized

  • Energy Star success has made it a critical marketing strategy

  • To maintain its success, adequate lead time is necessary

  • Other DOE regs allow 3 to 5 years lead time


Summary

SUMMARY

  • IF standby energy is included, incorporate it in the total annual energy use criteria, not separately

  • No need for prescriptive water requirement

  • Allow 24 months lead time for effective date
