Updated Ventilation Quality Mark guidelines ensure the performance of domestic ventilation systems following maintenance

From maintenance carried out to demonstrable performance

Proper maintenance of a ventilation system goes beyond simply cleaning the ventilation unit, ducts and valves, or replacing filters. Ultimately, the aim is to ensure that the entire ventilation system provides adequate air exchange and is correctly calibrated.

That is why the commissioning of the ventilation system is central to Ventilatiekeur. Once maintenance has been carried out, the installer checks and measures the system’s performance. If the measurement results indicate a need to do so, the system is readjusted. The work carried out, the measurement results and any areas for improvement are then documented.

This not only demonstrates that maintenance has been carried out, but also that the maintenance has resulted in a properly functioning ventilation system.

A key role for the installer

Installers play a crucial role in ensuring that ventilation systems function properly. They have the specialist knowledge required to inspect, maintain, measure and commission these systems. They also advise residents on the correct use and maintenance of their ventilation systems.

The updated guideline supports installers by setting out clear requirements and quality criteria for:

• inspection and maintenance of relevant plant components;
• assessment of the cleanliness of the ventilation system;
• measurement of ventilation capacity;
• checking that the entire system is functioning correctly;
• recalibrating the system;
• recording of work carried out and measurement results;
• reporting of non-conformities and necessary corrective actions;
• providing residents with information on correct use and maintenance.

This standardised approach enables installers to demonstrate both the quality and the results of their work.

Quality management system for housing associations and property owners

Ventilatiekeur offers housing associations, property owners and property managers a practical quality system for professional commissioning. The quality mark clearly sets out which works must be carried out, which performance parameters must be checked following maintenance, and how the results are to be recorded. This gives clients insight into:

• the technical condition of the ventilation system;
• the maintenance work carried out;
• the measured ventilation performance;
• the quality of the calibration;
• any discrepancies or necessary corrective measures;
• the operation of the entire system following maintenance.

Ventilatiekeur therefore helps clients to focus not only on the implementation and costs of maintenance, but also on the quality and performance of ventilation systems within their housing stock.

Guideline updated

The original Guideline on the Maintenance and Management of Domestic Ventilation dates from 2017. Since then, technology, knowledge and practical experience have evolved further. The guideline has therefore been revised with input from industry experts and aligned with current maintenance practices. This update strengthens the link between the craftsmanship of installers, professional commissioning and demonstrable ventilation performance. In this way, Ventilatiekeur contributes to well-maintained domestic ventilation systems and a healthy indoor climate for residents.

Available free of charge from 1 October

The updated Guidance on the Maintenance and Management of Domestic Ventilation Systems will be available to view and download free of charge from 1 October 2026 via the Binnenklimaattechniek Knowledge Centre’s knowledge base.

About Binnenklimaat Nederland and Ventilatiekeur

Ventilatiekeur is a quality mark developed by Binnenklimaat Nederland. The mark focuses on the commissioning of domestic ventilation systems following maintenance work. This involves checking, measuring and recording the operation and performance of the entire ventilation system.

Binnenklimaat Nederland represents the sector and is committed to quality, craftsmanship and a healthy indoor environment. To safeguard the quality and independence of the Ventilatiekeur quality mark, the management of the quality mark and the assessment process have been entrusted to the independent Binnenklimaattechniek Knowledge Centre.

This ensures that the development and substantive positioning of the quality mark are separate from its administration and assessment. Installers can use the Ventilatiekeur to demonstrate the quality and results of their work. Housing associations, property owners and property managers can use the quality mark to systematically ensure the quality of ventilation maintenance and the performance of ventilation systems.
