Abstract
The energy saving potential by upgrading windows in the European existing housing stock is more than 400 TWh per year based on an average saving of 100 kWh/m2 window area. The saving potential is twice that figure if the windows were upgraded to more energy efficient windows.
Window energy rating helps the buyers to compare windows energy performance and transform the market towards more energy efficient windows. European Window Energy Rating System, EWERS, was a SAVE project with participants from eight countries. The project resulted in full implementation of a rating system in two countries and in pilot projects in two countries. These four countries have different rating methods.
In this paper we are going to present the Swedish pilot project supported by the Swedish Energy Agency and present the energy saving potential when the energy consumption of products that are not run with electricity is becoming visible.
