Why install a VPH in the French-speaking part of Switzerland
Adopting a Hygro-regulated Positive Ventilation (VPH) meets several objectives, ranging from the protection of the building to the improvement of the comfort and health of the occupants. This system acts proactively by introducing filtered and tempered fresh air into the home.
Improvement of indoor air quality
A VPH introduces filtered and tempered outside air, creating a slight overpressure that pushes stale air outside through natural extraction vents. This process ensures that indoor air is constantly renewed, free from pollutants, allergens, and fine particles, thus improving respiratory health and the well-being of the inhabitants.
Intelligent humidity regulation
The hygro-regulated operation adjusts the airflow based on the humidity level measured inside the home. This effectively prevents condensation, mold, and damage related to humidity while optimizing energy consumption. This automatic regulation ensures an ideal balance between thermal comfort and efficiency.
Protection and enhancement of the home
By maintaining an optimal humidity level and eliminating pollutants, the VPH helps preserve the structure of the building and the interior finishes. It also contributes to the property value of your asset, providing an additional advantage in terms of comfort and energy performance.
Steps for installing an HPV in the French-speaking part of Switzerland
The installation of a Hygroregulated Positive Ventilation requires a rigorous methodology to ensure optimal operation and a long lifespan. Each step is carried out with care, from the initial diagnosis to commissioning.
How a VPH works
The Hygro-regulated Positive Ventilation is based on a simple yet effective principle: to inject filtered and tempered air into the home, creating a slight overpressure that naturally expels stale air outside.
Outside air is drawn in, filtered to remove dust, pollen, and particles, then tempered before being distributed within the home. This process ensures consistently high indoor air quality while reducing the introduction of external pollutants and improving the respiratory comfort of the occupants.
By supplying a volume of air slightly greater than that which is naturally extracted, the VPH generates a gentle overpressure in the home. This overpressure forces stale air to escape through designated outlets, thus preventing the infiltration of cold or damp air through cracks and gaps.
The hygro-regulated technology incorporates humidity sensors that regulate the airflow in real-time. This modulation allows for increased ventilation during humidity peaks (kitchen, shower) and reduces it when the air is dry, thus optimizing energy consumption.
How much does it cost to install an HPV in the French-speaking part of Switzerland
The price of an installation of Hygroregulated Positive Ventilation depends on several criteria: area to be ventilated, housing configuration, desired performance, chosen options, and complexity of the project. The prices below generally include the technical study, supply of materials, installation, adjustments, and warranty.
| Type of service | Price per m² (CHF) | Average total price (CHF) |
| Standard HPV | 90 to 130 | 2,000 to 3,200 |
| HPV with high-performance filtration | 110 to 150 | 2,500 to 3,800 |
| Connected HPV with integrated sensors | 130 to 160 | 2,800 to 4,200 |
These amounts are indicative and may vary depending on the quality of the selected equipment, technical constraints, and geographical location. A customized quote allows for precise determination of the cost based on your specific needs and the configuration of your home.
The advantages of a VPH installed by Avenir Rénovations Suisse
Calling on a qualified professional for the installation of a VPH guarantees optimal performance, regulatory compliance, and increased durability of the system. At Avenir Rénovations Suisse, each project is handled with precision and expertise.
Compliance with Swiss standards
Our installations strictly adhere to Swiss ventilation standards, ensuring safe and efficient operation. This compliance with requirements also ensures eligibility for certain aids or subsidies related to energy performance.
Optimization of performance and comfort
Each VPH is sized according to the volume to be ventilated, the insulation of the building, and its exposure. This precise sizing guarantees consistent air quality, stable indoor temperature, and controlled energy consumption.
Discreet and aesthetic integration
We ensure that the ventilation system is harmoniously integrated into your home. Visible elements, such as grilles and diffusers, are chosen and positioned to preserve aesthetics while ensuring maximum efficiency.
Regulations for the installation of a VPH in French-speaking Switzerland
In French-speaking Switzerland, the installation of a ventilation system is subject to certain rules aimed at ensuring safety, comfort, and energy efficiency. These obligations may vary by canton, but some requirements are common across the territory.
Permits and preliminary procedures
In most cases, the installation of a VPH inside the dwelling does not require a building permit. However, if visible modifications from the outside are planned (facade openings, ventilation grilles), a declaration or municipal authorization may be required. It is therefore recommended to check local rules before starting the work.
Compliance with Swiss technical standards
The installation of a VPH must comply with the requirements of the SIA 382/1 standard, which defines the minimum fresh air flow rates, calculation methods, and efficiency criteria. Adhering to these standards ensures optimal comfort, sustainable performance, and controlled energy consumption.
Electrical safety and OIBT compliance
Electrical connections must be made by a certified installer, in accordance with OIBT standards, ensuring the safety and compliance of the installation. This also helps prevent risks of failure or malfunction related to incorrect wiring.
Integration in co-ownership (PPE)
In the case of an apartment in a condominium, any project involving external modifications or affecting common areas must be approved by the assembly of co-owners. Aesthetic or technical constraints may be imposed to preserve architectural harmony.
Options and additional features to optimize a VPH
The Hygro-regulated Positive Ventilation can be enhanced with options that improve its performance, user comfort, and durability. These features can be integrated at installation or added later.
High-performance filtration
The integration of a fine particle filter (F7, F9, or HEPA) allows for the retention of a large portion of dust, pollen, spores, and allergens, ensuring pure and healthy indoor air. This solution is ideal for allergy sufferers or those living in urban areas with high pollution.
Humidity and CO₂ sensors
These smart sensors automatically adjust the air flow based on humidity levels and/or carbon dioxide concentration. They ensure healthy air while optimizing energy consumption, avoiding unnecessary operation during periods of low demand.
Connected control system
A connected control module allows for remote monitoring and control of the VPH via a smartphone or tablet. It is thus possible to adjust settings, schedule operating times, and receive alerts for necessary maintenance.
FAQ on the installation of a VPH in French-speaking Switzerland
Is a permit required to install a VPH?
As a general rule, a permit is not required for an indoor installation without visible external modifications. However, if the installation requires drilling into the facade or the roof, a municipal authorization may be required. Avenir Rénovations will assist you with these procedures.
Does a VPH consume a lot of energy?
The VPH is designed to be energy-efficient thanks to its humidity-controlled system that adjusts the flow according to needs. Its consumption remains low, making it a sustainable and cost-effective solution in the long term.
Can a VPH be installed in an old building?
Yes, the VPH is particularly suitable for renovations as it does not require a complex network of ducts. It can therefore be installed in an old building with minimal work while significantly improving air quality.
What is the difference between a VPH and a VMC?
The VMC extracts stale air and replaces it with naturally incoming air, while the VPH actively blows filtered and tempered air into the dwelling. This positive pressure operation improves hygiene and moisture control.
What is the lifespan of a VPH?
A quality VPH, well-maintained, can operate efficiently for 15 to 20 years. Regular maintenance, including filter replacement and checking the unit, is essential to extend its lifespan.
