The Department of Energy has an excel data sheet that may be downloaded as well as an online rating of the energy efficiency of appliances (refrigerators, dishwashers, clothes washers) that meet ENERGYSTAR standards. They also discuss appliances not labeled by ENERGY STAR. "it is always important to consider energy efficiency when purchasing any appliance. The Department of Energy offers guidelines and tips on purchasing Clothes Dryers, Ovens, Ranges, and Water Heaters.ΚΚ Also, be sure to read the FTC's "EnergyGuide to Major Home Appliances" for general information about shopping for an energy-efficient appliance."
The Department of Energy has an excel data sheet as well as an online rating of the energy efficiency of appliances that meet ENERGYSTAR standards including refrigerators,and dishwashers. Bottom Freezer configurations seem to be medium efficiency for size (top Freezers are most efficient, side by side least efficient), and are about 501-520 in annual KWH consumption. Side by Sides range upward from 568 as size increases.
Design considerations seem to suggest the wide but shallow models produced by Sub-Zero. The only sub-zero that is energystar compliant is the 650. A Sub zero distributer is available at Oakton Distributers at 780 Lively Boulevard Elk Grove Village, IL 60007. They seem to be a wholesale distributer, but have a showroom with Subzero, Thermador, Franke, Gaggenau, Broan, ULine. etc. They are changing the lines they carry and are less than friendly. Sub-zeros may also be seen at ABT electronics. The tradeoff here is between design considerations and energy efficiency. We need to explore if there are equivalents to a sub-zero in terms of design constraints that are more energy efficient.
DishwashersAsko, Viking, and Fisher Paykel seem to be among most energy efficient among the 262 types of dishwashers that are rated energystar compliant. When using just one drawer of their two drawer system, Fisher Paykel is very efficient. However, the clear winner is Asko which uses 340 KWH/year. Note that the Asko page includes energy comparisons with the other top of the line dishwashers! The median for all energy star dishwashers is about 530 KWH. Asko's N. Illinois dealer is O'Rourke Tollfree: 800-523-4730 Local: 800-523-4730. (It seems from the DOE table that Viking sells an Asko DVUD 141 as their product.)
Clothes washersThere are 72 models of clothes washers that meet energy star requirements. A primary consideration seems to be that side loading washers are roughly twice as efficient as top loading ones. It is claimed that they are also better for the clothes. fans no longer need to be ugly. Modern fans are available from various dealers in Illinois. The effect of a ceiling fan on comfort is discussed by an article in home energy. A recent developmment in fan design is found in the Gossamer II fan. An article describing its development may be found at Environmental Building News. An analysis of its effectiveness is given by its developer at Florida Solar Energy Center at the University of Central Florida. (They have a section devoted to Zero Energy Houses as well. ) Another article describing the fan notes its effeciency and also notes that it does not reverse direction. The electric motor of this fan is roughly as ineffecient as other fan motors and the difference is that the fan drives more air/watt. It also comes with a dimmable florescent bulb.
(It is interesting to note that a local electrical supply store was extraordinairely uncomplimentary about this fan. One suspects that this is due to the low price and higher energy output of this fan compared to the ones they carry.)
