Hellsau

Hellsau counts its ballots together with Höchstetten (shared ballot box), so the FSO publishes no separate result; its votes are included in the result of Höchstetten.

Terrain figures cover the whole municipal territory (swisstopo swissALTIRegio) — not the settlement point. Slope and south-facing share are resolution-dependent and measured at 40 m.

Modelled roof and façade potential from the BFE solar model — the electricity these surfaces could produce, not installed capacity or what the municipality actually generates today. The household figure divides the roof potential by 4'500 kWh per year, ElCom’s reference household (consumption profile H4, a 5-room apartment).

Premiums are set per canton and premium region. This area lies in premium region 2 of canton Bern. Shown is the average adult premium paid across the whole canton Bern (2024, BAG) — a region-specific average is not available in the cantonal data.

Vacancy rate from the BFS vacant-dwelling count (2025); building age and room count from the Buildings and Dwellings Statistics (2024). The average room count treats the ‘6 rooms or more’ class as 6, so it is a slight lower bound. The vacancy rate is volatile for small municipalities.
