Why Undertake an Energy Renovation in French-speaking Switzerland
Energy renovation offers numerous benefits that go well beyond simple savings on your energy bill. It also helps improve indoor comfort and reduce the environmental impact of your home.
Reduce Your Energy Expenses
By optimizing insulation and heating systems, you significantly reduce your consumption. The savings made each month allow for a quick return on the cost of the work while improving overall energy performance.
Improve Thermal and Acoustic Comfort
Better insulation retains heat in winter and coolness in summer. It also limits external noise disturbances, providing a more pleasant and healthy indoor environment on a daily basis.
Enhance Your Property Value
A well-rated home on the Swiss energy certificate (CECB) is more attractive for sale or rent. Buyers and tenants increasingly prefer energy-efficient and comfortable homes.
Steps of an energy renovation project in the French-speaking part of Switzerland
Each energy renovation project requires a structured approach to ensure the performance and durability of the work. Here is the process we follow at Avenir Rénovations.
Main energy renovation works
An energy renovation can include one or more types of interventions. At Avenir Rénovations, we adapt solutions based on the initial condition of the building and your objectives.
ITE involves covering the exterior walls with insulating material, followed by a protective coating. This technique eliminates thermal bridges and significantly improves energy efficiency without reducing the interior living space.
When ITE is not possible, internal insulation is an effective alternative. It involves installing insulating panels inside the walls, helping to limit heat loss and optimize comfort.
Heat loss through the roof can account for up to 30% of energy consumption. Insulating attics, whether converted or unconverted, is therefore a priority to maximize thermal performance.
Changing windows and exterior doors to double or triple glazing models improves thermal and acoustic insulation. It also helps limit air infiltration and reduce energy losses.
Replacing an old boiler with a high-performance model or switching to a heat pump reduces energy consumption. These modern solutions are more environmentally friendly and often eligible for financial aid.
A double-flow mechanical ventilation (VMC) improves indoor air quality and recovers heat from outgoing air. This allows for ventilation without energy loss, a major advantage in well-insulated homes.
How much do energy renovation works cost in French-speaking Switzerland
The cost of an energy renovation depends on the type of work undertaken, the materials chosen, and the area involved. The table below provides average estimates to guide you.
| Type of service | Price per m² (CHF) | Average total price (CHF) |
| External thermal insulation | 180 to 280 | 18,000 to 42,000 |
| Attic insulation | 80 to 140 | 8,000 to 14,000 |
| Replacement of double-glazed windows | 600 to 900 | 12,000 to 27,000 |
| Air/water heat pump | – | 18,000 to 28,000 |
| Installation of photovoltaic solar panels | – | 12,000 to 25,000 |
These prices generally include the technical study, supply, installation, adjustments, and warranty. A precise quote is necessary to assess the final amount, taking into account available assistance.
Financial Aid and Grants for Energy Renovation in French-speaking Switzerland
In Switzerland, several financial aids exist to encourage energy renovation work. These grants can come from cantons, municipalities, or national programs.
Cantonal and Municipal Programs
Each canton offers specific financial incentives for insulation, heating replacement, or solar panel installation. Municipalities may also provide additional aids.
Tax Deductions
Some expenses related to energy renovation can be deducted from taxes, depending on the regulations in your canton. This reduces the net cost of the work.
Federal Programs
National initiatives, such as the Buildings Program, support renovation projects aimed at reducing energy consumption and CO₂ emissions.
Options and Innovations for Your Energy Renovation
Energy renovation is no longer limited to classic solutions. Today, new technologies allow for even greater performance improvements while providing additional comfort in daily life.
Installation of Photovoltaic Solar Panels
Photovoltaic solar panels convert light into electricity, thus reducing your dependence on the grid. They enable the production of clean and renewable energy, tailored to your household's needs.
Solar Thermal Water Heater
A solar water heater uses solar energy to heat domestic water. It significantly reduces energy consumption related to hot water production and easily integrates on a well-exposed roof.
Reversible Heat Pump
A reversible heat pump provides heating in winter and cooling in summer. It captures heat from the air or ground to release it indoors, with reduced electricity consumption.
Home Energy Management
Home automation allows for remote control of heating, lighting, and ventilation. With sensors and intelligent programming, it optimizes energy use and prevents waste.
Regulations for Energy Renovation in French-speaking Switzerland
In Switzerland, energy renovation work must comply with specific rules regarding performance, safety, and aesthetics. These obligations may vary by canton and municipality.
Prior Authorizations
For certain works, such as external insulation or solar panel installation, a building permit or prior declaration may be required. Municipal services provide information on the necessary procedures.
Compliance with Energy Standards
Renovations must adhere to Swiss standards such as the SIA standard and the requirements of the CECB. This ensures an optimal level of energy performance in line with environmental goals.
Work in Co-ownership
In a condominium, works affecting the external appearance or common areas must be approved by the assembly of co-owners. This step is essential to avoid disputes.
Environmental Standards
The materials and equipment used must comply with current ecological standards, promoting the reduction of carbon footprint and sustainable resource management.
