There is often no single factor that determines the quality of indoor air in an office space. The IAQ of a building is a complexity of factors that influence the link to human health effects.
Concentrations of indoor air pollutants are influenced by changes in activities both within and outside the buildings, cleaning, heating and renovation regimes, the degree of ventilation, and the presence of products that are hazardous (including asbestos) or emit volatile organic compounds (VOCs).
CETEC has conducted several hundred IAQ assessments (ie air quality monitoring) and has a strong focus on the quantitative elements of IAQ.
Quantitative measures involve monitoring the following:
- Temperature and humidity
- Measurement of building ventilation rates (carbon dioxide) and the effectiveness of the ventilation system
- Concentration of selected indoor air pollutants, such as VOCs, carbon monoxide and formaldehyde
- Air particulates
- Airborne microbials
In addition to this quantitative approach, we use an internationally benchmarked occupant satisfaction survey that encompasses IAQ and in addition, also includes indoor environment quality (IEQ) elements. This occupant satisfaction survey captures subjective perceptions and qualitative feedback. Staff complaints are important and should be considered in addition to, or as a precursor to, quantitative measurements. OH&S risk assessment are then conducted.
Employers have a responsibility for providing staff with a healthy and safe working environment. This is a risk that needs to be managed carefully. With the knowledge and experience in occupational health and safety accumulated over the last twenty-five years and our commitment to confidentiality, CETEC is well equipped to determine the indoor air quality of the most complex of office spaces and provide practical solutions to assist organisations with protecting their staff.
Furthermore pre and post occupancy assessments can prevent problems. Remediation is expensive and disruptive.
