What do you save by changing to energy-rated windows? Complete the form and get an answer straight away!

Complete the form and find out your annual savings in Swedish kronor and kilowatt hours. To see which solution is best for your house you can calculate several options, in terms of both U-value and in expected future energy prices.

Calculate what you save


If you cannot find your location, select the nearest location.

The calculation is based on the assumption that a window has 1.44 m2 of window area, which is a standard window in a standard Swedish detached house.

Heating in the house
Select heating

Find your approximate energy price: Electricity price in SEK / kWh - Oil price in SEK / m - Pellet price in NOK / ton.Calculations are based on efficiency: Oil boiler 80 %, pellet boiler / burner 85 %.

The calculation acts as a pointer

This calculation is highly simplified and only provides a rough estimate of how much you can save with energy-rated windows. It does not take into account the fact that you can save still more energy by reducing your indoor temperature. For each degree by which you reduce your indoor temperature, you can add savings of approximately 5% of your heating costs to the result of the calculation.

Another and more detailed calculation method is the Life-Cycle Cost Calculation (LCC), which takes into account the energy costs over the house’s lifecycle.
