Purpose

n Market & Technology Assessment

• To characterize the residential dishwasher, dehumidifier, and cooking

products and commercial clothes washer markets to determine available

equipment efficiencies, manufacturers, shipments by equipment class, and

technologies available for increasing efficiencies.

n Screening Analysis

• To apply screening criteria established by DOE to determine which design

options to evaluate and which to screen out

n Engineering Analysis

• To evaluate design options that improve efficiency relative to the baseline

units

• To characterize manufacturer cost-efficiency relationships for higher efficiency

equipment

DW-1-2005, are prescribed by existing Federal standards.

Product Class

adequate flexibility to maintain consumer utility and wash

performance for different load sizes.

Cooking Products: Product Classes (Issue #2)

Product classes are based on energy source and cooking method.

Gas Cooktops Conventional burners

Electric Cookto s

Low or high wattage open (coil) elements

p

Smooth elements

Gas Ovens

Standard oven with or without a catalytic line

Self-clean oven

Electric Ovens

Standard oven with or without a catalytic line

Self-clean oven

Microwave Ovens Microwave oven with or without thermal elements

DOE invites comment on these product classes, specifically on whether

sealed burners warrant a separate product class for gas cooktops.

Commercial Clothes Washers: Product Classes (Issue #2)

n EPACT 2005 placed all commercial clothes washers in one product class and

defined a single energy efficiency standard and a single water efficiency standard.

n Statutory provisions do not prevent DOE from creating separate product classes, if

such differentiation is deemed appropriate.

n At this time, DOE decided to keep a single product class for the purposes of the

ANOPR, in accordance with Congress' determination.

n DOE considered the likely outcome of DOJ review of the potential impacts a single

product class would have on competition.

DOE invites comments on the specification of a single product class and how

to consider the impacts on the availability of products with certain

performance characteristics and features in considering Trial Standard

Levels.

EE-2006-STD-0127 COMMENT 23.4
Technology Assessment

n DOE identified technology options for each product covered in

this rulemaking from the following sources:

• Technical support documents from previous rulemakings

• Literature review

• Product specifications

• Stakeholder inputs

16

EE-2006-STD-0127 COMMENT 23.4
Screening Analysis Method

n Design options were screened using the following criteria:

• Technological feasibility

• Practicability to manufacture, install and service

• Adverse impacts on product utility or product availability
