This distribution describes recorded buildings, not your system's consumption or efficiency.
| Energy | Heating | Hot water |
|---|---|---|
| Gas | 43 % | 22.7 % |
| Heating oil | 20 % | 10.3 % |
| District heating | 6 % | 2.9 % |

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.
12.4 % of buildings mix housing with shops or offices.
For your renovation plans in Aarau, federal building register figures are vital. With 467 buildings under heritage protection, it is crucial to contact the municipality early to address permit requirements. The median house volume is 800 m3, which serves as a key indicator for scaling insulation or heating upgrades. Please note that data coverage regarding volume is partial, as only 20 houses were measured according to the SIA 416 standard. We recommend verifying the precise dimensions of your specific property before starting any works to ensure your renovation budget remains accurate and effective for your project.
