Engineering Features - Energy Efficient Appliances

Appliances used in the home everyday make up for a significant portion of the total energy use. Purchasing efficient appliances can significantly decrease this energy use and in turn decrease the homeowner's utility bills. Water use will decrease as well. Many of these efficient appliances are available from standard suppliers and look just like the appliances you use today.

Washer, dryer, dishwasher
Washing MachineThe washer, dryer, and dishwasher used in the CU home are being donated from ASKO which provides appliances that look great, use less energy, and are built to last. The front loading W6221 washer uses as little as 5.7 gallons of water per load (versus 44 for most top-loaders, 28 for domestic front-loaders), saving as much as 16,000 gallons per year. The Sensor Level Controlª System, a unique device that automatically adjusts the water level according to the absorption rate of the clothing, saves about 20% per load. ASKO also uses 75% less electricity than top-loaders, and up to 40% less than domestic front-loaders for a normal wash load. It also features a super quick wash which when used, increases the savings even further. ASKO washers clean so efficiently; you need only one-third the detergent and no bleach.

DryerThe dryer that will be used in the house is the ASKO T701. This model features automatic, timed, and air fluff drying programs and three temperatures. The T701 has improved airflow and higher drying temperatures so it dries faster than standard dryers. The drying time is also decreased by the fact that the ASKO washer has an exceptionally fast spin cycle, which removes most of the water before the clothes reach the dryer.

Dish WasherThe D1716 dishwasher that the CU house will have is quiet, 20% more capacity, great cleaning without pre-rinsing, seven wash programs, and two wash and rinse temperature options. An ASKO dishwasher uses only 4.6 gallons for a normal cycle (3.9 for a Quick Wash program). That compares to 7-10 gallons used by many competitors, many of which do not clean nearly as well. ASKO dishwashers can save about 1,500 gallons every year of its 20-year life. It uses less electricity and about half the detergent. The ASKO appliances not only function well while they are in use but 80% of the materials used can be recycled.

RefrigeratorThe refrigeration needs of the CU Solar Decathlon house will be covered with a GR9SHKXKB model Whirlpool¨ refrigerator. This refrigerator combines high performance with high efficiency. It not only easily meets the new standards for refrigerators, which requires them to use 30% less energy than the 1993 standards by July, 2001, it additionally consumes 10-15% less energy with more highly-efficient compressors and condensers to meet 2001 Energy Star¨ qualifications. Whirlpool¨ Refrigerators use the Accu-Chillª System with Foam-In-Place Doors and Double Tub Construction to maintain the correct temperature in both fresh-food and freezer compartments. The result is increased strength and accurate temperature control for storing food and beverages.

Microwave/Convection Oven
MicrowaveFor the cooking needs of the house, the CU team has chosen to use the GE Profile Advantium 120 , a combination microwave and oven. This unit is ideal for the small 800 square ft house as it conserves space and energy. The revolutionary Speedcook technology cooks oven-quality food up to four times faster than a conventional oven. It provides all the same functions including baking, browning grilling, and roasting - all with no preheating. Other cooking options include traditional oven, microwave and warming Ð all at the touch of a button.

CooktopThe cooktop being used in the house is the Jenn-Air¨ 30" Induction & Radiant Element Cooktop (link to This item offers two magnetic induction elements and two Ultra Quick-Startª radiant elements. The induction elements are unique in that they transfer heat directly to the cookware, which has to be made of a ferrous material, rather than releasing waste heat into the house. Induction cooking offers precise temperature control, letting you adjust the heat from boil to simmer in an instant. The two radiant elements provide efficient, even heating, and can be used with standard cookware.
