Standards and calculations

What are the averages per appliance?

Below you can find what aspects have been included in the calculation of the average consumption per appliance.

Washing machines

A washing machine’s annual consumption depends on the energy use, the load capacity and use by the consumer. The YAECI project takes this information from the energy label, which now published the annual consumption in kilowatthours for each individual model on the market.

Tumble dryers
Tumble dryers have an energy label on which the consumption per standard cycle is stated. Actual consumption depends on the load and how often the tumble dryer is used.

  • On average, a tumble dryer is used 155 times a year.
  • The average load is 3.4 kg; for a machine with a capacity of 5 kg this means a 78% decrease in energy use each time. The assumption is that this factor also applies to machines with a higher capacity.


  • A washer-dryer is used to do washing just as often as a washing machine.
  • The machine’s dryer function is used more often than a separate tumble dryer because it has a lower capacity. On the other hand, it is possible that tumble dryers are, on average, loaded with larger volumes.
  • The assumption is that the best calculation of actual consumption is to use 220 times a year with an average 80% lower consumption due to under-capacity loads

Data from the new energy label is used, which published the models' annual electricity consumtion.

Air conditioners
There are two main types of air conditioners:

  • single and multi split units
  • single and double duct units

The calculation of the annual running cost of the single and multi split units is based on the  average annual consumption which is provided by the new energy label. For the single and double duct air conditioners only the hourly energy consumption is provided and the annual running costs will be estimated also based on the average annual hours of use. These usage patterns will be uniquely defined in each country, based on a literature review and expert opinion.

Is the saving mode/eco mode included in the calculation?

These are options that consumers can set up themselves. The reduced contrast will result in lower energy consumption. This is comparable to doing washes at 30°C instead of 40°C or having a dishwasher with an eco mode as well as a standard mode. These options were not included when determining average consumption, unless they are already directly covered by the energy label information.

What average energy price is used?

Electricity prices change all the time and are different from consumer to consumer, and the contract that the consumer has concluded with their energy supplier. Within this project, the average national electricity proce is being used, and continuously updated.

What standards are used to calculate the energy costs?

The data for individual products is originating from figures on the energy label, which is measured using international standards, valid in all around the EU, and supplied by product manufacturers.
