Ventilation Failure Investigation
Trusted since 1999 · Proven delivery partner
When a ventilation system fails to perform — whether through mechanical failure, poor commissioning, or degraded performance — the impact on indoor air quality is immediate. Green Air Monitoring investigates ventilation failures to diagnose the cause and provide a remediation pathway.
Symptoms of Ventilation Failure
Ventilation problems often present as IAQ complaints before mechanical failure is identified.
- Elevated CO₂ levels indicating insufficient fresh air
- Stuffy or stale-feeling air in occupied spaces
- Temperature or humidity control problems
- Persistent odours that don't dissipate
- Uneven air distribution — hot/cold spots
- Increased dust deposits from poor filtration
Diagnostic Assessment
We assess ventilation system performance through CO₂ monitoring (ventilation adequacy), airflow measurement at diffusers and grilles, static pressure testing across system components, fan performance verification, damper position and operation checks, and control system review.
Remediation Guidance
Our investigation reports identify the specific component or configuration causing the failure, with costed remediation options ranked by effectiveness and urgency. We can verify the effectiveness of remediation through follow-up monitoring.
