This distribution describes recorded buildings, not your system's consumption or efficiency.
| Energy | Heating | Hot water |
|---|---|---|
| Gas | 32 % | 21.3 % |
| Heating oil | 28 % | 21.2 % |
| Heat pump | 38 % | 32.8 % |
| Electricity | 1 % | 17.6 % |
| Wood | 2 % | 0.3 % |
| Solar thermal | 0 % | 6.7 % |
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.
For your renovation projects in Au, data from the federal building register indicates that at least 9 buildings are subject to heritage protection, requiring early coordination with the municipality to secure necessary permits. Please note that data coverage is partial for certain indicators: information regarding the year of renovation and building volume according to the SIA 416 standard is not available in the current records. We advise you to verify these technical specifications directly with local authorities before proceeding with modernization plans or insulation upgrades to ensure your project aligns with municipal requirements and building standards.

Sizing your future heat pump is a crucial step to ensure comfort and savings. In Au (SG), the local design outdoor temperature determines the power required to heat your building efficiently.
An oversized pump will run in short cycles, reducing its lifespan, while an undersized unit will struggle in extreme cold. It is recommended to have a heat loss calculation performed by a professional.
To estimate the budget required for this specialized equipment, consult the RenoIndex online estimator, which will provide you with a reliable estimate in Swiss francs.
When installing outdoor air-water systems, noise pollution must be taken into account. These units must strictly comply with noise limits toward neighbors to avoid disputes.
Strategic placement away from rest areas and the use of acoustic covers are common solutions. At the same time, it is advisable to check whether your neighborhood can be connected to a priority district heating network before finalizing your project.
RenoIndex supports you in this planning phase by helping you estimate the costs for your acoustic compliance work.
The success of a thermal installation depends on good integration into the existing heating system. A heat pump is most efficient with low-temperature emitters such as underfloor heating.
If you have radiators, adaptation might be needed to maintain optimal efficiency. Planning work outside the heating season is ideal to avoid periods without thermal comfort.
To get a precise idea of the costs associated with your system integration, you can use the RenoIndex calculator, a reference tool for a transparent estimate in Swiss francs.
Using a certified professional is highly recommended for any heat pump installation. An expert will be able to assess technical feasibility, check access points, and ensure the chosen equipment is suited to your home's layout in Au (SG).
The budget can vary depending on the chosen technology and necessary electrical or hydraulic connection work. By using RenoIndex, you benefit from a cost estimate based on market standards, allowing you to better prepare your investment in Swiss francs.
