| Gas | 58 % | 44.6 % |
| Heating oil | 25 % | 18.8 % |
| District heating | 4 % | 3.3 % |

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.
16.6 % of buildings mix housing with shops or offices.
For renovation projects in Biel, official building register figures highlight that nine buildings are under heritage protection, necessitating early consultation with municipal authorities for permit requirements. Regarding building volume, data coverage is currently very limited, with only four buildings measured according to SIA 416 standards out of 2011 units, showing a median volume of 683.5 m3. Because this data is highly partial, homeowners must conduct their own professional site measurements. Accurate volume assessments remain crucial for planning the appropriate scale of your heating and insulation upgrades to ensure your renovation project meets all technical and regulatory standards.
