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.
13.2 % of buildings mix housing with shops or offices.
For your renovation plans in Altendorf, federal building registry data provides vital insights for your budget. The median house volume is recorded at 1250 m3 according to the SIA 416 standard, which is essential for scaling heating and insulation requirements. Please be aware that data coverage is partial, as 800 buildings rely on other or unknown standards. Regarding heritage protection, information is missing for most of the housing stock. We strongly recommend contacting the municipal authorities early in your planning process to clarify any building restrictions or permit requirements before proceeding with your renovation project.

Roof insulation is a key step to reducing your energy expenses. In Switzerland, insulating the roof together with the covering is often eligible for the Buildings Programme.
High-performance insulation limits thermal bridges and significantly improves interior comfort during summer and winter. It is advisable to consult a specialist to determine the most suitable insulating materials for your structure.
Remember to check current eligibility conditions with official bodies before finalizing your plans to maximize your chances of receiving financial support.
If you are planning to install solar panels, it is essential to coordinate these works with your roof renovation. If your house already has solar panels, their removal and refitting must be budgeted precisely in your overall quote.
This step increases the labor time for the contractors but ensures perfect roof sealing after the work. Anticipate these additional costs to avoid any budgetary surprises during the project.
A well-prepared roof is the best foundation for a durable and profitable solar installation.
The local climate directly influences the choice of materials for your roof. At altitude, snow loads and intense frost impose specific structural requirements.
It is crucial to select tiles or roofing materials capable of resisting these specific constraints over the long term. A roof designed for alpine conditions will last much longer without requiring frequent repairs.
Discuss with your roofer the most resistant solutions for snow accumulation and the freeze-thaw cycles common in the region.
A successful renovation begins with total control of your budget. It is recommended to request quotes from several companies to compare offers in detail. Ensure that each quote includes the cost of materials, labor, and the disposal of old debris.
To obtain a solid basis for comparison and avoid estimation errors, do not hesitate to use our RenoIndex simulator. This will provide you with a clear price range for your roof project in Switzerland before you proceed with a specialized contractor.
