Indoor Air Quality Assessment & Testing

Given that we spend about 90% of the time indoors, it’s necessary that people have healthy and comfortable indoor working conditions, when these conditions are not met, job satisfaction, productivity and health can potentially be compromised. Indoor Air Quality (IAQ) in a building can have a direct impact on the health and well being of its occupants.

Our team assesses, tests and investigates the indoor air quality in your facility in the following ways:

  1. To identify any concerns and issues that have arisen due to a complaint or at your request
  2. To provide a baseline or validation of the current indoor air quality levels within a space to provide assurance that its meeting its desired level of satisfaction.

What's Involved?

Step 1: Initial assessment

During the initial assessment we will meet with your Facilities Management team to complete our Building Attributes Worksheet which outlines the details of the building and use of the occupied space as well as identification of any areas of concern or occupant complaints.  A thorough inspection of the HVAC and filtration systems will be completed as well as the occupied spaces.

Step 2: Testing

Using our state of the art GrayWolf IAQ testing equipment, we set up the equipment and sample the air in your facility from anywhere from 24 hours to 7 days to measure and record the following information:

Indoor Air Quality Parameters

    • Temperature
    • Relative humidity
    • Particulate counts for PM2.5 and PM10
    • Carbon dioxide (CO2)
    • Carbon monoxide  (CO)
    • Total volatile organic compounds (TVOC)


Industrial Gas Parameters

    • Ammonia (NH3)
    • Chlorine (Cl)
    • Formaldehyde (HCHO)
    • Hydrogen Sulfide (HS)
    • Nitrogen Oxide (NO)
    • Sulphur Dioxide (H2S)

Step 3: report & recommendations

On completion of the IAQ test, all data points are compiled into a formal report detailing the results based on the parameters measured which may identify areas of concern. Any areas of concern identified will include recommended corrective measures. If through our initial testing, we cannot identify the issue we may recommend additional testing and investigation.  In 70-80% of cases, we can identify the problems after our initial test and no further investigation is required. In cases where further investigation is required, we will recommend additional testing and investigation which will be out of scope of the initial assessment and testing. 

The Benefits of Indoor Air Quality Assessment

An indoor air quality assessment allows us to get a thorough understanding of your space and its existing air quality. This way we are able to make expert recommendations for you based on your unique needs.
