Appliances are grouped and reported as major appliances, or small appliances/miscellaneous end-uses.

Refrigerators, freezers, clothes washers, clothes dryers, dishwashers, stoves and ovens are included in the “Major Appliance” category. Using the number and approximate age of major appliances, the model estimates energy consumption, based on historic sales-weighted efficiency data. This section contains the energy estimation methodology for each appliance. The estimated consumption across equipment types is summed to arrive at the “Major Appliance” category totals.

The model allows estimation of energy consumption for about seventy-five miscellaneous enduses or small appliances. Most small appliances are electric, but several gas powered appliances are included. The model also has a provision for user-defined appliances. The default energy consumption estimates for the included miscellaneous end-uses can be viewed here.
