For the analyses, the products are divided into different functional categories (e.g., water heating, space cooling, or dishwashing) and into different classes according to their energy source (such as natural gas, propane, oil or electric power) and other performance features such as capacity of the appliance. A separate efficiency requirement is established for each class.

Pursuant to section 325 of the Energy Conservation and Policy Act (ECPA) (42 U.S.C. 6295), the U.S. Department of Energy Office of Energy Efficiency and Renewable Energy (DOE/EERE) considers seven factors when setting energy conservation standards, which include the following:

To establish the data required in assessing the various impacts and determining the cost and fuel savings, the Office of Energy and Renewable Energy (EERE) conducts several analyses that evolve during the four-step rulemaking process.

Seven criteria are used in every rulemaking of this kind:

  1. Economic impact on consumers and manufacturers;

  2. Lifetime operating cost savings compared to increased cost for the product;

  3. Total projected energy savings;

  4. Impact on utility and performance

  5. Impact of any lessening of competition

  6. Need for national energy conservation

  7. Other factors the Secretary considers important.

Step 1:
Advance Notice of Proposed Rule Making (ANOPR)

The analyses conducted for the ANOPR2 include:

  • Market and technology assessment

  • Screening analysis

  • Engineering analysis

  • Preliminary manufacturer impact analysis

  • Product price determination

  • Life cycle cost and payback period analyses

  • Shipment analysis

  • National impact analysis

Key input information used in these analyses includes: national energy use, product process and shipment data.

Key output information includes: product classes, technology options, design options, product designs, life cycle costs, payback periods, national energy savings, net present values, conversion capital expenses and direct employment impacts.


The Energy Independence and Security Act of 2007 replaces ANOPR with a workshop.
