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.
11.1 % of buildings mix housing with shops or offices.
For renovation planning in Glarus, the building register data is partial. The median volume for the 50 houses measured under the SIA 416 standard is 562.5 m3, helping you gauge the scale for heating and insulation upgrades. Regarding heritage protection, out of 307 known buildings, 1 is officially protected. If your property is classified, you must contact municipal authorities early to understand permit requirements, as this significantly impacts renovation scope and costs. Assessing these official figures helps you set realistic expectations for your construction project in Glarus and navigate the administrative process efficiently from the start of your planning phase.

Solar thermal collectors use solar radiation to heat a heat transfer fluid that circulates towards a storage tank. These systems perform particularly well in Switzerland and generally cover a large portion of hot water needs during the summer period.
By reducing the operation of your main boiler during sunny months, you extend its lifespan while achieving significant savings.
It is essential to orient the collectors correctly, ideally facing south, to optimize the annual energy yield of your installation in Glarus.
A successful installation relies on meticulous planning. If you plan to combine your solar thermal collectors with a heat pump, a rigorous sizing study is essential to ensure system compatibility and overall efficiency.
The choice of technology, whether flat plate or evacuated tube collectors, will depend on your roof configuration and water requirements. Correct sizing prevents overheating in summer and ensures an optimal supply throughout the year.
RenoIndex supports you in this process by helping you calculate the various components needed for your project.
These subsidies aim to encourage the energy transition and make renewable technologies more accessible to owners. It is advisable to find out about current programs before starting work.
To get a clear view of net costs after deducting potential subsidies in the canton of Glaris, consult the RenoIndex estimator for a reliable and quick budget estimate.
Planning must integrate architectural constraints and applicable regulations. During the design phase, ensure that your roof structure can support the weight of the collectors and that the storage tank fits in your technical room.
Working with qualified professionals ensures an installation compliant with Swiss standards and long-term system durability. Do not forget to plan for the regular maintenance of your installation to maintain a high level of performance over the long term.

A well-maintained solar thermal system generally has an average lifespan of 20 to 25 years. Regular maintenance of the heat transfer fluid and annual component checks help maximize this longevity and ensure consistent hot water production efficiency throughout the period.
Yes, the system also works in winter, even in cold weather, as the collectors capture solar radiation. However, the yield is lower due to fewer hours of sunshine. This is why a backup system, such as a boiler or a heat pump, is essential to ensure comfort.
The need for a building permit depends on the nature and zone of your project. It is recommended to consult your municipality's technical department or a local professional before starting the process, in order to confirm the specific requirements applicable to your home and roof.
Although technically possible for some DIY enthusiasts, it is strongly discouraged to do it alone. The installation requires plumbing and electrical skills, as well as compliance with safety standards. Hiring a qualified professional is essential to benefit from warranties and ensure optimal system performance.
