Audit of ventilation systems

The ventilation system audit verifies indoor air quality by studying the performance of ventilation systems and their compliance with current standards.

It rests on two fundamental pillars: dust measurements and leak tests.

Dust measurements on ventilation systems

Ventilation systems naturally accumulate dust particles and other contaminants over time, which can adversely affect indoor air quality and the proper operation of installations.

Dust measurements are used to assess the cleanliness of ducts and check their compliance with EN 15780 which defines acceptable cleanliness thresholds according to classification (new buildings, existing buildings, or after cleaning).

Analysis of results and targeted intervention

Following these measurements, our IGIENAIR interpret and analyze data collected to identify areas requiring intervention.

Our IGIENAIR teams then proceed to complete hygienization of air networks to re-establish compliant and sustainable cleanliness conditions.

Dust measurements can also be carried out after cleaning air networks to ensure absence of contamination and compliance with defined criteria.

Leak test objectives

Air-tightness testing is used to check the air-tightness of quality of ventilation ducts and air-conditioning systems, whether new or existing.

It guarantees compliance with standards NF EN 12237, NF EN 1507, and NF EN 12599, These are essential to prevent energy loss and ensure optimum ventilation.

Leak testing serves several purposes:

Assessing conduit quality

Identification of any leaks in the networks.

Ensuring compliance

Check that networks comply with watertightness classes defined by standards.

Optimizing energy performance

Air loss control to improve system efficiency.

AEROSEAL leak test

Our approach

Tests are performed using standardized equipment for measuring leakage rates at different pressures and assess pipe conformity. An inspection visual and technique is carried out to locate any leaks.

Compliance is validated if the measured tightness class is less than or equal to the target class. At the end of its tests, IGIENAIR provides a detailed report including measurement results.

Our teams interpret the results and suggest corrective solutions to seal air networks and optimize energy consumption.
