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.
7.2 % of buildings mix housing with shops or offices.
For homeowners in Wollerau, RegBL figures provide vital context for planning renovations. The median house volume is 1060.5 m3 according to the SIA 416 standard, though this measurement is only documented for 28 out of 886 residential buildings. Data regarding the year of renovation and heritage protection status is incomplete, with no buildings officially classified as protected. Because coverage is partial, it is essential to contact the municipality early in your planning process. Early consultation ensures you understand local requirements for heating and insulation projects, helping you manage the scope and scale of your renovation accurately.

Installing solar thermal collectors is an effective solution to sustainably reduce your energy bills. In general, these systems cover a large part of the hot water demand during the summer months, thus limiting the use of fossil fuels or electricity.
Beyond financial savings, you actively contribute to protecting the environment by reducing your CO2 emissions. It is a long-term investment that strengthens the energy independence of your home.
To estimate the budget required for installing this equipment on your roof in Wollerau, check our free RenoIndex online calculator.
The success of a solar installation relies on precise sizing. It is crucial to adapt the collector surface to the actual consumption of your household.
If you plan to combine solar collectors with a heat pump, a sizing study is essential to ensure optimal synergy between both technologies. This step helps to avoid summer overheating and optimize winter operation.
Before you start, do not forget to use the RenoIndex simulator to get a reliable cost estimate for your installation tailored to your home's current configuration.
Although policies vary, researching cantonal incentives is a key step to reduce your initial investment. To know the probable amount of your renovation budget before applying to official bodies, visit the RenoIndex website.

The choice of equipment depends on your roof configuration and hot water needs. There are two main types of collectors: flat plate or evacuated tube.
Evacuated tube collectors generally offer higher efficiency, especially when sunlight is limited, while flat plate collectors are often more affordable. A professional site analysis is recommended to make the best choice.
To get a clear idea of the total cost based on different technologies, we invite you to test the RenoIndex price simulator, which will effectively guide you through your energy renovation project.

Yes, solar thermal collectors capture diffuse radiation, allowing them to work even when the sky is cloudy. However, efficiency is naturally lower than in full sun. They continue to preheat the water, thus reducing the load on traditional heating systems.
A well-maintained solar thermal installation can operate efficiently for 20 to 25 years. Regular maintenance is essential to ensure the longevity of components and maintain optimal efficiency. It is advisable to have the system checked periodically by a specialist.
The required area depends on the number of occupants and the volume of hot water consumed daily. As a general rule, you need about 1 to 1.5 m² of collectors per person. Correct sizing is crucial to avoid summer overheating and ensure consistent efficiency.
