Notes on Refrigerator Energy Factors:

1. Energy Factor has units of (cubic feet•day/kWh), where cubic feet is adjusted volume.

2. Source: (AHAM 1996) (AHAM 2003) - AHAM changed the reporting of refrigerator efficiencies after 1996. Annual data is available for the “General” category. Data for the other refrigerator types for years subsequent to 1996 was derived from the “General” refrigerator efficiency by scaling the efficiency for a particular type of refrigerator proportional to the annual change in efficiencies in the “General” refrigerator category.

3. Data has been held at 2003 levels for subsequent years.
