The U.S. Department of Energy Solar Decathlon Appliances Contest is designed to mimic the appliance use of an average U.S. home. Teams earned points for refrigerating and freezing food, washing and drying laundry, and running the dishwasher. Points are awarded for:
Maintaining the refrigerator temperature between 34°F (1.11°C) and 40°F (4.44°C)
Keeping the freezer temperature between -20°F (-28.9°C) and 5°F (-1.5°C)
Washing a load of laundry within a specified period of time
Returning a load of laundry to a total weight less than or equal to the load's total weight before washing using active or passive drying methods
Running the dishwasher through a complete, uninterrupted cycle, at some point during which a temperature sensor placed in the dishwasher has to reach 120°F (48.9°C).
