| Heating oil | 29 % | 22.2 % |

Each line gives the share of buildings using that energy, separately for heating and for hot water. The two columns do not always reach 100%: some buildings combine two systems, or reported none.
A standard non-condensing boiler is usually older and less efficient.
9.9 % of buildings mix housing with shops or offices.
For your renovation projects in Grenchen, the official RegBL figures provide essential insights despite partial data coverage. With 4 buildings listed under heritage protection, it is crucial to contact the municipality early to navigate permit requirements. The median building volume of 755 m3, derived from a limited set of 4 measurements, helps define the scale for your insulation or heating upgrade plans. Since renovation years are not recorded and volumetric data is sparse, conducting an on-site assessment remains a necessary step to ensure your renovation budget and planning are accurate and reflective of your specific property.
