Why install a ventilation system in the Swiss Romandy
Good ventilation is much more than just comfort; it is essential for maintaining a healthy indoor environment, protecting the building structure, and optimizing overall energy performance.
Improvement of indoor air quality
A modern ventilation system allows for continuous renewal of indoor air, eliminating pollutants, excessive humidity, and odors, while introducing filtered fresh air. This constant action promotes respiratory health, improves daily well-being, and helps limit allergic or asthmatic risks.
Prevention of humidity and mold problems
By quickly evacuating the water vapor produced in humid rooms such as the kitchen or bathroom, a ventilation system prevents condensation and preserves materials. This prevention significantly reduces the risks of mold, stains on walls, and structural damage, while maintaining a healthy environment for occupants.
Contribution to energy efficiency
High-performance ventilation systems are designed to minimize heat loss while ensuring optimal air renewal. They help maintain a stable indoor temperature, reducing heating consumption and improving thermal comfort throughout the year.
Steps for installing a ventilation system in the French-speaking part of Switzerland
The installation of a ventilation system follows a precise methodology to ensure optimal performance and full compliance with regulatory requirements.
The different ventilation systems available
There are several technologies suited to the needs of Swiss homes. The choice will depend on the layout of the premises, air quality objectives, and budget constraints.
CMV, whether single-flow or double-flow, extracts stale air from humid rooms and ensures the supply of fresh air through dedicated air inlets. The double-flow version also recovers heat from the extracted air to preheat the incoming air, offering significant energy savings. This centralized system guarantees continuous and uniform regulation of air renewal throughout the home.
HPV injects filtered and tempered air into the home, creating a slight overpressure that pushes stale air out through the exhaust vents. Its hygro-regulatable operation automatically adjusts the flow rate according to the ambient humidity level, ensuring intelligent ventilation management. This technology is particularly effective for sanitizing damp or poorly ventilated homes while controlling energy consumption.
MVB injects filtered and preheated air into the home via a central unit, forcing stale air to exit naturally through designated openings. This system improves air quality, regulates humidity, and limits cold air infiltration, while contributing to thermal comfort. It can be equipped with high-performance filters to protect occupants from external pollutants and allergens.
How much does it cost to install a ventilation system in the French-speaking part of Switzerland
The price of a ventilation system depends on many parameters: the type of technology chosen (VMC, VPH, or VMI), the area to be ventilated, the expected performance level, the complexity of the site, and any additional options. The prices below generally include the technical study, supply of materials, installation, final adjustments, and warranty.
| Type of service | Price per m² (CHF) | Average total price (CHF) |
| Single flow VMC | 70 to 120 | 1,200 to 2,600 |
| Double flow VMC | 120 to 200 | 4,500 to 9,000 |
| VPH | 90 to 150 | 2,000 to 4,000 |
| VMI | 100 to 160 | 2,200 to 4,500 |
These prices are indicative and may vary depending on the configuration of the home, technical constraints, the quality of the chosen equipment, and the specific needs of the client. A personalized quote is essential to accurately assess the necessary budget.

Regulations for installing a ventilation system in the Swiss Romandy
In the Swiss Romandy, the installation of a ventilation system is governed by strict standards aimed at ensuring occupant safety, energy performance, and environmental compliance. Requirements may vary by canton, but some points are common to all.
Permits and preliminary procedures
For an indoor installation without facade modification, a building permit is generally not required. However, if the intervention involves visible openings from the outside or aesthetic changes, a municipal authorization request is mandatory. Processing times may vary from one municipality to another, and it is important to anticipate these procedures to avoid delays.
Compliance with ventilation standards
Installations must meet the requirements of standard SIA 382/1, which defines minimum fresh air flow rates, airtightness criteria, and performance control methods. This compliance is essential to ensure air quality, limit energy losses, and maintain occupant comfort.
Electrical safety and OIBT compliance
Any electrical connection related to the ventilation system must be carried out by a certified professional, in accordance with OIBT standards. This requirement ensures the safety, durability, and proper functioning of the system while meeting legal obligations regarding electrical installation.
Integration in co-ownership (PPE)
In co-ownership, any modification affecting common areas or the exterior appearance of the building must be validated by the general assembly. Some co-ownerships also impose restrictions regarding the positioning of extraction vents and exterior grilles.
Options and additional features to optimize a ventilation system
To further enhance performance, user comfort, and the lifespan of a ventilation system, several options can be integrated during installation or added later.
High-performance filtration
The addition of fine particle filters (F7, F9, or HEPA as needed) helps to capture the vast majority of dust, pollen, and other allergens. This device is particularly recommended for homes located in urban areas or for occupants suffering from respiratory allergies. Regular maintenance of these filters ensures optimal air quality and preserves the longevity of the system.
Humidity and CO₂ sensors
These smart sensors automatically adjust the ventilation flow based on humidity levels and/or carbon dioxide concentration in the air. This dynamic control helps maintain healthy air while reducing energy consumption when maximum ventilation is not necessary.
Connected systems and remote control
With a connected interface, it is possible to monitor air quality, energy consumption, and the proper functioning of the system in real time. The user can also adjust the ventilation from a smartphone or tablet, schedule time slots, or activate specific modes according to their needs.
FAQ on installing a ventilation system in the French-speaking part of Switzerland
Do you need a permit to install a ventilation system?
In general, a permit is not required for an indoor installation without facade modification. However, for work involving external or visible penetrations, municipal authorization is mandatory. Our teams assist you with these administrative procedures.
What is the difference between a VMC, a VPH, and a VMI?
The VMC extracts stale air and replaces it with fresh air through air inlets. The VPH blows in filtered air regulated according to humidity. The VMI injects filtered and preheated air, creating a slight overpressure that expels stale air through the designated outlets.
What maintenance is required for a ventilation system?
Regular maintenance is essential to preserve performance and air quality. It includes cleaning or replacing filters, checking ventilation outlets, inspecting ducts, and a complete annual check by a professional.
Can a ventilation system be installed in an old house?
Yes, but the installation must be adapted to the building's configuration. For older homes, solutions like VMI or VPH are often preferred as they require less extensive work than a centralized VMC.
How long does a ventilation system last?
With regular maintenance, the average lifespan of a ventilation system is 15 to 20 years. The quality of the installation, the choice of materials, and the frequency of maintenance directly influence this longevity.
