Appliances: 70.124 out of 100 possible points


The Appliances contest is designed to mimic the appliance use in the average U.S. home but using less energy. Points are earned for refrigerating and freezing food, washing and drying laundry, and running the dishwasher.

To earn points, student teams must:

  • Maintain refrigerator temperature ranges within 34°F/1.11°C to 40°F/4.44°C.
  • Maintain freezer temperature ranges within -20°F/-28.9°C to 5°F/-1.5°C.
  • Wash and dry 10 loads of laundry during the contest week.
  • Run the dishwasher five times during the contest week.
