Review of Site (Point-of-Use) and Full-Fuel-Cycle Measurement Approaches to DOE/EERE Building Appliance Energy-Efficiency Standards-Letter Report (2009)

Currently, the Department of Energy (DOE) sets appliance efficiency standards using primarily "site" (or point-of-use) measurements, which reflect only the energy consumed to operate the appliance. Site measurements allow consumers to compare energy efficiency among appliances, but offer no information about other energy costs involved. This congressionally mandated report from the National Research Council recommends that DOE consider moving over time to the use of a full-fuel-cycle measure of energy consumption for assessment of national and environmental impacts. Using that metric would provide the public with more comprehensive information about the impacts of energy consumption on the environment, the economy, and other national concerns. This volume discusses these matters and offers several related findings and recommendations together with supporting information.
