Swiss window industry introduces voluntary energy labelling for windows

Share this Post:

In January 1 2015 the voluntary Swiss window energy labelling, Energieettikette für Fenster, was introduced. It has been launched with the support of the Swiss Professional Association for Windows and Facades (Schweizerischen Fachverband Fenster- und Fassadenbranche-FFF) and the Swiss Centre of Windows and Facades (Schweizerischen Zentrale Fenster und Fassaden-SZFF).


The labelling system assesses the energy quality of the window in winter by an energy equivalent U-value divided into 7 efficiency classes from A to G indicated by coloured arrows. Windows of efficiency class A will provide more energy gains than transmission losses throughout the heating period.
