Local context: Climate and building stock

Montreux, situated at an altitude of 382 meters, enjoys a privileged position on Lake Geneva, but its climate imposes precise requirements.8 °C, your building's thermal performance is essential.

The heating demand is estimated at 2560 Kj/year, highlighting the importance of efficient insulation to maintain lasting comfort in your home.

The diverse building stock in Montreux must now adapt to current energy standards. The municipality, holding the 'Energy City Gold' label since 2016 and renewed in 2025, places the energy transition at the heart of its priorities.

Whether you own an old apartment or a villa, the challenge lies in balancing the preservation of architectural character with the new technical constraints imposed by the municipal energy master plan and the upcoming municipal climate plan for 2026.

Priorities for energy renovation

Energy renovation in Montreux follows ambitious goals : reducing greenhouse gas emissions by 70% and primary energy consumption per capita by 40% by 2040. The absolute priority remains the insulation of the building envelope.

A well-insulated facade and high-performance windows drastically limit heat loss, making your heating more efficient and your home healthier against ambient humidity due to the lakeside climate.

In addition to insulation, the optimization of technical systems is crucial. Replacing obsolete installations with renewable technologies helps achieve the target of 80% renewable final energy aimed for by the municipality.

7 °fh), which requires adequate treatment to protect your new heating systems and sanitary installations against premature scaling.

Heating, district heating and cantonal rules

Montreux is currently developing a major infrastructure : the district heating network called MontCAD. Managed by the company MontCAD, a partnership between the municipality and Romande Energie, this network will use heat from Lake Geneva.

Between 2027 and 2035, this project aims to cover 25% of the city's heating needs by connecting approximately 250 buildings, particularly from Clarens to Territet. If your building is located within the target area, choosing this connection is a sustainable option.

For buildings that cannot be connected, installing a heat pump is an encouraged alternative. Administrative procedures in the canton of Vaud are simplified for this equipment.

However, for air-water or air-air models, particular attention must be paid to noise pollution, as it is taken into account during the review of your file. Regardless of your choice, the Building Program offers subsidies for replacing obsolete fossil or electric systems.

Permits and heritage

Carrying out work in Montreux requires understanding the authorization procedures.

In general, the canton of Vaud applies a simplified procedure or grants a permit exemption for many interventions, particularly for solar photovoltaic installations, window replacement, or heat pump installation, provided they do not significantly modify the exterior appearance or dimensions of the building.

However, caution is required if your building is located in a protected area or is part of recognized architectural heritage. In these specific cases, rules are stricter to preserve the visual identity of the municipality.

For any solar installation, you must provide a complete file including an announcement form, a site plan, a cadastral extract, as well as photographs of the building. It is recommended to consult the municipality or the prefect in advance to validate the compliance of your project before ordering any equipment.

Financial aid and taxation

The financial support system in Montreux is based on the Building Program, which offers subsidies for facade insulation, window replacement, solar thermal installations, and heat pump installation. These aids aim to lighten the initial investment.

Regarding photovoltaics, you can benefit from a federal one-time payment calculated based on the power of your installation, which can be supplemented by local aid depending on current opportunities.

Tax-wise, the canton of Vaud offers advantageous levers. You can choose each year between the flat-rate deduction or the deduction of actual costs. Energy investments (replacement of obsolete elements or installation of renewable systems) are 100% deductible.

If these expenses exceed your net income for the current year, the balance can be carried forward over the next two tax periods. Note, however: if you opt for the carry-forward of expenses, the flat-rate deduction is no longer accessible for that tax period.

Finally, note that the municipal tax rate is set at 65 percent until 2025.

Planning and selecting companies

Successful renovation in Montreux requires rigorous planning. Start with an energy assessment of your property to identify priorities: roof, facade, or heating system. In a dynamic market, it is advisable to request several quotes from qualified local companies.

Always check their certifications and experience in energy renovation work, as the quality of implementation determines the eligibility for subsidies and the real efficiency of your equipment.

Anticipate administrative procedures. Even if the simplified procedure is common, compiling the file for a photovoltaic installation or a heat pump requires precision (photos, plans). Once the company is chosen, establish a precise schedule integrating material delivery times.

Also, make sure to coordinate the work to minimize inconveniences, especially if you live in the home. Finally, keep a rigorous trace of all your invoices, as they will be essential for your future requests for tax deductions or subsidies from the competent bodies.
