Replacing old windows is one of the most cost-effective ways to reduce a building's energy consumption. In Switzerland, several cantonal and federal programmes subsidise this work. Here is what you need to know to benefit.
The Building Programme — national framework
The Building Programme (Das Gebäudeprogramm) is a federal scheme co-financed by the cantons. It funds measures to improve the building envelope, including windows. Conditions vary by canton, but the principle is consistent: installed windows must achieve a maximum required Uw value (typically Uw ≤ 1.0 W/(m²·K)). Applications must be submitted before work begins.
Canton of Berne
The canton of Berne offers grants for window replacement in existing residential buildings. The amount varies according to the glazed area replaced and the Uw values achieved. Applications are handled by the cantonal energy office (OCEN). BO Fenster works regularly in the Biel/Bienne area and can assist you in putting together your application.
Canton of Fribourg
Fribourg also offers subsidies under the Building Programme. Applications are handled by the Energy Service (SdE). Property owners can combine the cantonal grant with the tax deduction for maintenance and energy renovation work.
Other Swiss cantons
Vaud, Valais, Geneva, Zurich and most other cantons offer similar programmes. Amounts and conditions vary. Visit the official portal www.dasgebaeudeprogramm.ch for up-to-date information for your canton.
