This distribution describes recorded buildings, not your system's consumption or efficiency.
| Energy | Heating | Hot water |
|---|---|---|
| Gas | 58 % | 44.6 % |
| Heating oil | 25 % | 18.8 % |
| District heating | 4 % | 3.3 % |
| Heat pump | 10 % | 6.7 % |
| Electricity | 1 % | 23.6 % |
| Wood | 2 % | 1.1 % |
| Solar thermal | 0 % | 1.4 % |
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.

A battery is worthwhile when solar output clearly exceeds your daytime use. By storing the excess energy generated during sunny hours, you avoid purchasing expensive grid electricity once the sun goes down.
This makes your home more self-sufficient and sustainable. The installation also helps smooth out demand peaks, relieving pressure on the power grid while improving the efficiency of your solar panels.
Analyzing your current consumption profile is an essential first step before investing in such technology in Biel to ensure long-term energy savings.
Size capacity by evening consumption, not panel power. A common mistake is oversizing the battery, which unnecessarily increases costs. It is crucial to calculate your average nighttime needs precisely.
A battery that is too small will not cover your usage, while a battery that is too large will never fully charge during winter months. Make sure to tailor your capacity to your lifestyle.

Check compatibility with your existing inverter before buying. Some newer models are hybrid units that already integrate battery management, while others require additional components.
It is recommended to contact a qualified electrician in Biel to evaluate the state of your electrical system. Ensure the chosen area for the battery is dry, temperate, and well-ventilated to guarantee its longevity.
An installation compliant with Swiss standards ensures not only the safety of your building but also the optimal performance of your home energy management system.
Investing in a battery depends on your consumption habits. In Switzerland, self-consumption is becoming increasingly attractive due to rising electricity tariffs.
Planning your project requires a holistic view : consider future needs, such as the potential installation of an EV charging station, which might justify a larger storage capacity.
Although grants can vary, a well-thought-out system is a sustainable investment. Use RenoIndex to get a clear price range and plan your renovation budget with peace of mind.
