What subsidies for roof and facade renovations in Switzerland?

The importance of high-performance roofing and façades

Well-insulated roofing and façades play a crucial role in a building's energy efficiency. They limit heat losses in winter and heat gains in summer, thereby reducing heating and cooling needs. This translates into significant energy savings and a reduction in your carbon footprint.

The different types of insulation

On the Swiss market, there is a wide range of high-performance insulating materials. Each of them has its own specifics in terms of acoustic, thermal and/or fire insulation. To give just a few examples, we can mention:

• Mineral wool (rock wool or glass wool): excellent thermal insulation, excellent fire resistance, good acoustic insulation (particularly against airborne noise).
• Wood wool: a natural and eco-friendly insulator, offering good thermal and acoustic performance, especially against impact noise. Moderate fire resistance.
• Cellulose wadding: an eco-friendly insulator made from recycled paper, offering good thermal performance and effective acoustic insulation against airborne noise. Moderate fire resistance.
• Expanded polystyrene (EPS) or extruded polystyrene (XPS): lightweight synthetic insulators that are easy to install. Excellent thermal performance, but poor acoustic insulation and flammable.

The choice of material will depend on the specifics of your project and your priorities (thermal performance, budget, environmental impact). To obtain subsidies in Switzerland, insulating materials must comply with certain standards. These vary according to the cantonal or municipal subsidy programme and the type of energy renovation undertaken.

Roof renovation: the key stages

This is a complex project that requires careful planning:

1. Assessment of the condition of the roof: a precise diagnosis will make it possible to determine the works required (repair, insulation, replacement).
2. Choice of materials: select quality materials suited to your region and to the climatic constraints.
3. Request for authorisation: check whether authorisations are needed from your municipality.
4. Carrying out the works: call on qualified professionals to guarantee works carried out in line with the standards.

Façade refurbishment: improving appearance and performance

These energy renovation works not only improve the appearance of your home, but also optimise its thermal insulation:

• External insulation (ITE): an effective solution for optimal insulation and a reduction of thermal bridges.
• Internal insulation (ITI): a simpler solution to carry out, but less effective than ITE.
• Façade refurbishment: refreshes the appearance of your home and protects the walls from the elements.

The subsidy programme in Switzerland: major financial support

In Switzerland, the Buildings Programme run by the Confederation and the cantons encourages energy renovation through subsidies. This financial aid can cover part of the costs of insulating the roof and façades.

Eligibility criteria for the Buildings Programme to obtain a subsidy

There is no single list of criteria that applies throughout the country. However, general guidelines common to most cantonal programmes can be identified. Here are the eligibility criteria generally encountered for making a building more energy-efficient thanks to the Buildings Programme.

---

Concerning the building:

• Type of building: existing residential buildings (single-family homes, multi-family apartment buildings). New constructions are often excluded.
• Age of the building: requirements concerning the minimum age of the building.
• Building ownership: owners, co-owners and sometimes tenants (with the owner's agreement).

---

Concerning the renovation measures:

• Eligible measures: the Buildings Programme generally supports thermal insulation of the building envelope (roof, walls, windows, floors) and the replacement of heating systems and hot water production with more efficient and renewable systems.
• Technical requirements: the measures must comply with minimum technical requirements in terms of energy performance, defined in the technical sheets of the cantonal programme.

---

Concerning the subsidies:

• Subsidy amount: it varies according to the type of measure, its energy performance and the canton.
