# #23.4
The Energy Policy and Conservation Act (EPCA) directs DOE to consider seven factors when setting energy conservation standards

t ^ l 1. Economic impact on consumers Life-cycle cost analysis and manufacturers Manufacturer impact analysis 2. Lifetime operating cost savings Life-cycle cost analysis 3. Total projected energy savings National impact analysis 4. Impact on utility or performance Screening Analysis Engineering analysis 5. Impact of any lessening of Manufacturer impact analysis competition 6. Need for national energy National impact analysis 

### conservation 7. Other factors the Secretary Environmental assessment considers relevant Utility impact analysis Employment impact analysis 3

# #23.4 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 10

Dishwashers: Product Classes (Issue #2) Product classes, based on specifications in ANSI/ARAM Standard DW-1-2005, are prescribed by existing Federal standards. Product Class Compact Standard 

### Capacity < 8 place settings plus 6 serving pieces >_ 8 place settings plus 6 serving pieces


### DOE invites comment on whethertheseproduct classes offer adequate flexibility to maintain consumer utility and wash performance for different load sizes.

## Dehumidifiers: Product Classes Product classes are established by EPACT 2005.



### ^roduct Class by ... 25.00 Pints/Day or Less 25.01 - 35.00 Pints/Day 35.01 - 45.00 Pints/Day 45.01 - 54.00 Pints/Day 54.01 - 74.99 Pints/Day 75.00 Pints/Day or More

## 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. 14

# #23.4

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. 15

## 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

## 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 • Adverse impacts on health or safety
