Renovations, heritage and volumes
For renovation projects in Biel, official building register figures highlight that nine buildings are under heritage protection, necessitating early consultation with municipal authorities for permit requirements. Regarding building volume, data coverage is currently very limited, with only four buildings measured according to SIA 416 standards out of 2011 units, showing a median volume of 683.5 m3. Because this data is highly partial, homeowners must conduct their own professional site measurements. Accurate volume assessments remain crucial for planning the appropriate scale of your heating and insulation upgrades to ensure your renovation project meets all technical and regulatory standards.

Energy optimization and insulation
Roof insulation is one of the most effective levers for reducing heating bills. During a renovation in Biel/Bienne, it is advisable to combine the replacement of the roofing with the installation of high-performance thermal insulation.
Under the Buildings Programme, this combined approach can often make your work eligible for federal or cantonal financial aid.
Adequate insulation prevents heat loss in winter and maintains pleasant coolness in summer, while sustainably increasing the value of your home on the local real estate market.
Managing solar installations
If your current roof is already equipped with solar panels, their removal and refitting are essential steps in the renovation process. It is crucial to include these additional costs in your initial budget to avoid unpleasant surprises.
Panels must be handled carefully to preserve their integrity and yield after the work.
Take this opportunity to check the state of your electrical installation and optimize the layout of the panels on the new roof structure, ensuring maximum efficiency for your future energy needs.
Material choice based on climate
In Biel/Bienne, weather conditions can vary, directly impacting your roof's durability. At altitude, heavy snow loads and freeze-thaw cycles significantly influence the choice of roofing materials.
It is essential to opt for robust and certified solutions that withstand local weather. Discuss the most suitable options with your craftsman, such as resistant terracotta tiles or durable metal systems.
A well-chosen material not only guarantees optimal protection against water infiltration but also reduces regular maintenance needs over the years.
