BFE solar factsheet ↗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).

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.
