How much sun does this address get?
A flat that glows in the midday sun during a summer viewing can sit for weeks in the shadow of the neighbouring hill in winter. The difference determines heating costs, mood and whether the balcony is usable in March — but a single viewing won’t show it.
Ubivo computes the sun path for your address from the Swiss terrain model and the surrounding horizon: how many sunshine hours are realistic over the year, when the terrain casts shade and — most importantly — what it looks like in the winter half-year, when the sun is low.
Enter your target address — you instantly get the building-precise sun and shade analysis plus all other quality-of-living factors, free. Only the personalisation to your situation is paid (commute, taxes, health insurance).

This is what your result looks like
Sunshine hours per year
Direct sunshine hours per year at the location, based on horizon and shading. The Swiss average is around 1'500 hours.
For your address the report computes real values — this is an illustrative example.
What Ubivo measures here
Sunshine hours (year)
Realistic sunshine hours over the year, derived from topography and horizon shading.
Winter sun
The critical value: how much sun arrives when it sits low, in the winter half-year.
Terrain shading
When surrounding hills and slopes shade the address — independent of neighbouring buildings.
Orientation
How the location sits relative to the sun’s path — the basis for balcony and living quality.
Frequently asked questions
How does Ubivo compute the sunshine hours?
From the official Swiss elevation model (swisstopo) and the computed horizon around the address, combined with the sun’s position over the year. Every value with source and date.
Do you also account for neighbouring buildings?
Yes — the building-precise shading from direct neighbouring buildings is included in the free location report (via building polygons). Only the personalisation is paid.
Why is winter sun so important?
In winter the sun sits low — even a moderate hill or slope can shade an address for weeks. That is exactly what a summer viewing doesn’t show.
Is the estimate free?
The building-precise report (all factors) is free. Only the personalisation to your situation is paid (commute, taxes, health insurance).
