This distribution describes recorded buildings, not your system's consumption or efficiency.
| Energy | Heating | Hot water |
|---|---|---|
| Gas | 6 % | 6.1 % |
| Heating oil | 16 % | 15.2 % |
| District heating | 31 % | 30.1 % |
| Heat pump | 25 % | 24.3 % |

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.
11.4 % of buildings mix housing with shops or offices.
For your renovation plans in Grabs, please note that the federal building register data is currently partial. With a median house volume of 776 m3 calculated from a sample of 30 buildings based on the SIA 416 standard, these figures provide a baseline for estimating the scale of your heating or insulation upgrades. As the register covers 2120 buildings, please be aware that information regarding renovation years is unavailable and no properties are recorded as protected heritage sites. Consequently, you should rely on professional on-site assessments for these specific aspects while using the volume data as a reference.
