Renovations, heritage and volumes
For your renovation plans in Bern, the RegBL data provides essential context. Heritage protection applies to 5 identified buildings, requiring early contact with the municipality to secure necessary permits. Regarding building volume, the median is 770 m3 based on the SIA 416 standard, though these measurements cover only 20 out of 4279 houses. This partial data significantly impacts how you assess the scale of heating or insulation works. Please be aware that the limited data coverage means these figures serve as a general guide, and professional verification of your specific property details is recommended for accurate budget planning.

Housing stock and building age
The majority of buildings in Bern were constructed before 1960. A significant 27% were built before 1919, while 32% date from 1919 to 1945. With 5 buildings under heritage protection, verifying your property's status is essential.
The median building volume is 770 m3 according to SIA 416 standards, though data is limited.
Given the age of the building stock, focus is often required on building envelope insulation and preserving historic architectural elements, which must be factored into your budget and choice of materials.
Heating and energy
The energy mix for heating in Bern is dominated by gas (44%) and oil (31%). However, heat pumps are gaining ground, now representing 13% of installations, complemented by 8% from district heating. Replacing old systems with renewable solutions is encouraged.
7%. Before making changes, assess your building's current energy performance and inquire about support programs available in the canton of Bern to facilitate the transition to efficient heating systems and achieve long-term energy cost savings.
Permits
Local authorities require complete documentation, including plans and energy certificates. For projects including solar installations or heating system replacements, contact municipal technical services before finalizing your budget.
A well-prepared application file significantly speeds up the permitting process.
Priorities for owners
To optimize investments, prioritize insulating the building envelope, such as roofs and facades, as these are the biggest sources of heat loss in older buildings.
Once insulation is improved, replacing the heating system becomes more efficient, reducing the required capacity. Consider window upgrades and solar integration where possible.
Prioritize renovations that increase property value while improving thermal comfort and sustainability, and always keep a budget reserve for unforeseen technical issues.
