Indoor Air Quality (IAQ) Testing

Comprehensive assessment of indoor air pollutants, ventilation effectiveness, and environmental factors affecting occupant health and comfort.

Why Indoor Air Quality Matters

Australians spend approximately 90% of their time indoors, where air can be 2-5 times more polluted than outdoor air. Poor indoor air quality contributes to sick building syndrome, reduced cognitive performance, and exacerbation of respiratory conditions including asthma and allergies.

Modern buildings often prioritize energy efficiency over ventilation, creating tight building envelopes that trap pollutants. Off-gassing from building materials, furniture, and cleaning products combines with biological contaminants and insufficient fresh air exchange to create problematic indoor environments.

The Ventilation Challenge

Adequate ventilation is fundamental to good IAQ. We measure actual air exchange rates and CO2 levels as indicators of ventilation effectiveness. High CO2 (above 1000ppm) indicates insufficient fresh air supply and correlates with reduced cognitive function and occupant complaints.

What We Measure

Carbon dioxide (CO2) levels
Carbon monoxide (CO)
Volatile organic compounds (VOCs)
Particulate matter (PM2.5, PM10)
Temperature and relative humidity
Formaldehyde
Ozone levels
Air exchange and ventilation rates

Symptoms of Poor IAQ

Poor indoor air quality often manifests through a constellation of non-specific symptoms that improve when occupants leave the building. If you or building occupants experience any of the following, IAQ testing may be warranted:

Headaches and fatigue
Difficulty concentrating
Respiratory irritation
Eye, nose, and throat irritation
Dizziness or nausea
Allergic reactions
Worsening asthma symptoms
General feeling of unwellness indoors

Our Assessment Approach

We conduct IAQ assessments using calibrated professional instruments with documented accuracy. Testing includes spot measurements, time-weighted averages where appropriate, and assessment under typical occupancy conditions. Our reports identify pollutant sources, assess ventilation adequacy, and provide prioritized recommendations for improvement.
