Indoor Outdoor Environment Testing & Analysis

Indoor Air Quality

It is generally recognised that Australians spend 90% or more of their time indoors. Poor air quality in indoor environments can have a significant impact on human health, increasing the risk of illness. Good air quality includes introduction and distribution of adequate ventilation air, control of airborne contaminants and maintenance of acceptable temperature and relative humidity. In some cases, indoor environments can have levels of pollutants higher than the levels found outside. The key indoor air contaminants include biological contaminants, chemical pollutants and particle matter.
Aside from factors that directly impact the level of pollutants that people have exposure to, a range of environmental and personal factors could affect how people perceive air quality


Volatile Organic Compounds (VOCs)

VOCs refers to organic chemical compounds that have significant vapour pressure and can adversely affect the environment and human health. VOCs are emitted as vapours from certain solids and liquids and a variety of chemicals. Concentrations of VOCs can be significantly higher indoors than outdoors. VOCs are emitted from many building products that may be present in an office environment, they could include including paints and lacquers, cleaning supplies, building materials and furnishings, printers, permanent markers, correction fluids, glues and adhesives. Health effects related to exposure to VOCs could include eye, nose and throat irritation, headaches and nausea, damage to liver, kidney and central nervous system, and some of these organics are suspected or known to cause cancer in humans.


Factors that affect comfort and productivity

Beside the factors that directly impact the levels of pollutants to which people are exposed, a number of environmental and personal factors can affect how people perceive air quality. These factors include:

  • Odours
  • Temperature
  • Air velocity and movement
  • Heat or glare from sunlight
  • Furniture crowding
  • Stress in the workplace or home, work space ergonomics
  • Noise and vibration levels
  • Feelings about physical aspects of the workplace including location, work environment,
    availability of natural light and the aesthetics of office design.

Some studies have shown that psychological, social and organisational factors may modify individuals and organisations responses to concerns in the office environment. Psychosocial factors related to job stress including job satisfaction, interpersonal conflict and lack of job security can be associated with workplaces where Indoor Air Quality (IAQ) issues are of concern.
