In Ittigen, the federal building register lists 1'539 residential buildings and 5'888 dwellings. These municipal benchmarks help put your home in context, but do not replace an individual assessment.
61 % built before 1980
Construction year does not reveal past renovations: check the current insulation condition.
57 % · Heating oil
This distribution describes recorded buildings, not your system's consumption or efficiency.
| Energy | Heating | Hot water |
|---|---|---|
| Gas | 15 % | 11.2 % |
| Heating oil | 57 % | 37.9 % |
| District heating | 1 % | 0.5 % |
| Heat pump | 15 % | 6.6 % |
| Electricity | 7 % | 39.9 % |
| Wood | 4 % | 1.5 % |
| 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.
6.4 % of buildings mix housing with shops or offices.
For your renovation projects in Ittigen, the RegBL figures provide vital context regarding your property. Currently, data coverage for house volume and renovation years is only partial, which limits automated estimation capabilities. Although official records indicate no heritage-protected buildings, we strongly advise contacting the municipality early to confirm permit requirements. Since the volume for the 840 recorded houses does not follow the SIA 416 standard, you will need to provide precise measurements when planning your thermal insulation or heating upgrades. Accurate site-specific data remains essential for determining the scope and budget of your renovation.

A battery is worthwhile when solar output clearly exceeds your daytime use. In Ittigen, as elsewhere in Switzerland, most households produce plenty of energy when the sun is at its peak but consume the most in the evening.
Without storage, this excess is fed into the grid at a price often lower than the purchase cost. With a battery, you save this energy to power your appliances or lighting after dark, thereby improving the overall profitability of your photovoltaic system.
Size the capacity of your battery according to evening consumption, not the total power of your solar panels. A system that is too large is an unnecessarily expensive investment, while one that is too small will not cover your needs.
Analyze your nighttime consumption profile to choose a suitable model. The goal is to maximize the self-consumption rate without oversizing the equipment.
Consult local professionals to analyze your load profile and get reliable technical recommendations for your residential project.
Before buying a battery, carefully check compatibility with your existing inverter. Some inverters are specifically designed to communicate with certain battery brands, while others require additional communication gateways.
Poor compatibility can lead to efficiency losses or safety issues during charging and discharging.
It is recommended to hire a qualified electrician in Ittigen to perform the connection and ensure the system is correctly configured to optimize energy exchanges in real time with your installation.
The cost of a battery system depends on the storage capacity in kWh, the technology used, and the complexity of the on-site installation. Although battery prices have decreased in recent years, the budget remains significant.
To help you plan your finances, the RenoIndex estimator offers a clear and free estimate tailored to your situation in Ittigen.
By comparing different technical solutions, you can better evaluate the return on investment and choose the system that best suits your home energy needs.

Most modern solar batteries use lithium-ion technology and have a lifespan of between 10 and 15 years. Their performance gradually decreases over time and with the number of charge cycles performed.
Yes, it is entirely possible to add a battery to an existing installation. You simply need to check the technical compatibility with your current inverter or consider adding a hybrid inverter or an AC coupling system.
This depends on your configuration. A standard system shuts down for safety reasons during a grid failure. Only systems equipped with a specific backup function can power your home during a power outage on the public grid.
No, most solar batteries are designed to be maintenance-free. It is simply recommended to periodically check the proper functioning of the system via your tracking application to detect any possible anomalies.
