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.
5.8 % of buildings mix housing with shops or offices.
For renovation planning in Domat/Ems, federal building register figures provide essential insights. With partial data coverage, the median volume for the 14 buildings measured under SIA 416 is 926 m3, helping you gauge the scale for heating or insulation upgrades. Additionally, out of 1656 total buildings, 2 are currently listed under heritage protection. If your property is impacted by these heritage status requirements, you must contact municipal authorities early in your project timeline. Engaging with the municipality promptly is vital for navigating permit processes and ensuring all renovation plans strictly adhere to local regulatory standards.

Solar thermal collectors capture energy from the sun to heat a fluid circulating in a closed loop. This heat is then transferred to a storage tank.
These systems typically cover a large portion of hot water needs during summer, drastically reducing the demand on your main boiler during sunny months.
To ensure optimal performance, it is advisable to check the orientation of your roof and the tilt of the panels, as these factors directly impact the annual energy yield of your domestic system.
One of the advantages of solar thermal energy is its ability to complement other technologies. For instance, combining solar collectors with a heat pump requires a rigorous sizing study.
This analysis ensures that both systems work in harmony without excessive energy use. Such hybridization is ideal for maximizing your home's energy self-consumption.
Considering this synergy during the planning phase is crucial to ensure your investment pays off in the long term while optimizing thermal comfort within your home.
These incentives aim to encourage the adoption of renewable energy. It is recommended to check the applicable cantonal programmes regularly before starting your work to verify your eligibility.
Remember that RenoIndex provides a cost estimate to help you budget for your project before applying for grants.
A successful solar installation requires meticulous preparation. Start by assessing the condition of your roof and its capacity to support the panels. Next, engage certified professionals to conduct a comprehensive energy audit.
Good planning includes choosing the right equipment while adhering to safety and installation standards. By using RenoIndex to estimate your costs, you gain a solid foundation to compare quotes from local companies.
This key step helps you avoid financial surprises throughout the construction process.

Yes, the system functions as long as there is solar radiation, even in cold weather. However, the yield is reduced compared to summer. It therefore requires a backup system, such as a boiler or heat pump, to maintain an adequate water temperature during the darkest months of the year.
A well-maintained solar thermal installation typically lasts between 20 and 25 years. Regular maintenance, including checking the heat transfer fluid and mechanical components, is essential to maximize this longevity and ensure the efficiency remains optimal throughout the years.
The necessary area mainly depends on your hot water consumption and the number of occupants in the home. Generally, an area of 1 to 1.5 m² per person is recommended for domestic hot water production alone. A professional will perform a precise calculation based on your specific needs.
For specific advice, contact a certified installer in Switzerland or a local energy advisor. For a quick and free initial budget estimate, you can use the online RenoIndex simulator, which will provide you with a price range tailored to your project.
