I understand that energy star ratings are designed to give the consumer some idea how efficient a device is, but I want to know how they calculate their kwh per year rating? I would assume that it has to do with how many kwh’s per complete cycle X so many cycles per year, but how many cycles per year is their mark to measure by.
I ask this because I acquired a kill a watt kwh measuring device and I want to know how many cycles to multiply one complete cycle of my clothes dryer by to compair its “energy star rating”.

Energy star rating for washers is based on 392 cycles per year. I was unaware that they gave ratings to dryers, since that is one of the most inefficient appliances. However, I would assume that you would use 392 cycles per year since washers and dryers typically go together.
