Ventilatiekeur
The design, installation, commissioning and maintenance of ventilation systems is a specialised field. To ensure good indoor air quality, the system must be properly commissioned and regular maintenance is essential. Ventilatiekeur is a quality mark for domestic ventilation systems whereby not only the maintenance carried out, but also the operation and performance of the entire ventilation system are checked, measured and recorded. This provides demonstrable evidence that maintenance has been carried out in accordance with the guidelines and that the ventilation system is functioning correctly. Ventilation specialists who hold the Ventilatiekeur certification can be found in the Hallmark Register.
Ventilatiekeur and housing managers
Why a quality mark?
The indoor air quality of homes can be improved, both for owner-occupied and rental properties. While homeowners are responsible for their own ventilation systems, in rental properties, this responsibility lies with the housing association or landlord, who ensures proper maintenance and living comfort.
Indoor air quality is a key consideration when it comes to living comfort. The Ventilatiekeur scheme was developed to raise indoor air quality to a higher standard. Ventilatiekeur focuses on expert maintenance, inspection, measurements and, where necessary, the recalibration of domestic ventilation systems. This provides residents and clients with insight into both the work carried out and the system’s performance.
Take care of your own healthy living environment
Proper ventilation is essential for your health. A well-ventilated home ensures sufficient fresh air, helping you wake up rested and feel more energetic during the day. However, many homes still suffer from poor ventilation. Research shows that 1 in 10 homes has mould, nearly half contain tobacco smoke, and in many houses, indoor air pollution is worse than outdoor air. Clearly, ventilation needs improvement.
Few people realise that we shape our indoor climate ourselves. Cooking releases particulate matter, and both washing and cooking produce significant moisture. Even breathing increases CO₂ levels indoors. For your health and that of your family, it is crucial to refresh indoor air regularly. So, make ventilation a priority!
What are ventilation systems?
In the past, ventilation happened naturally in homes. Small gaps and cracks allowed fresh air to flow in and stale air to escape. However, modern homes are built airtight, meaning ventilation must now be managed differently.
Mechanical air extraction is a ventilation system that ensures continuous air removal, constantly refreshing the indoor air. In this system, fresh outdoor air enters through opened ventilation grilles.
Balanced ventilation is a type of mechanical ventilation that also supplies fresh air. The system preheats incoming cold air using the warm indoor air before expelling it outside. This makes balanced ventilation an energy-efficient system. Additionally, ventilation can be adjusted using sensors that measure CO₂ and humidity.
Proper use and regular maintenance are essential for all types of ventilation systems. Seek advice from a certified ventilation specialist who holds the Ventilatiekeur certification.
