This distribution describes recorded buildings, not your system's consumption or efficiency.
| Energy | Heating | Hot water |
|---|---|---|
| Gas | 32 % | 34.1 % |
| Heating oil | 30 % | 30.1 % |
| District heating | 3 % | 2.5 % |

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.
11.3 % of buildings mix housing with shops or offices.
For your renovation projects in Freienbach, the official building register provides key indicators for planning. The median building volume is 1420 m3; however, this figure based on SIA 416 standards is only available for 23 of the 1289 houses, indicating that data coverage remains very partial. This information is critical for assessing the scale of necessary heating or insulation upgrades. As there are no records for renovation years or heritage protection status, we advise homeowners to contact the municipality directly to clarify local building regulations and permit requirements before initiating any renovation work on their property.
