Indoor Environmental Quality

Indoor Environmental Quality (IEQ)

Indoor environmental quality (IEQ) can significantly affect the health, comfort, productivity and job satisfaction of workers in indoor environments. The following are common symptoms of poor IEQ:

  • Dryness and irritation of the eyes, nose, throat, and skin
  • Headache
  • Fatigue
  • Shortness of breath
  • Hypersensitivity and allergies
  • Sinus congestion
  • Coughing and sneezing
  • Dizziness
  • Nausea

Control of air contaminants, produced either inside the building or infiltrating from outside, plays a big part in maintaining optimal IEQ. These include:

  • Carbon dioxide – from human respiration and combustion sources
  • Carbon monoxide – produced by combustion sources such as furnaces and vehicular traffic outside
  • Chemicals off-gassed from new furniture, carpets, wall board and paint – such as formaldehyde and other volatile organic compounds (VOCs)
  • Dust and fibres – from carpets, insulation materials, wall board, human skin scales, and outside sources
  • Mould – water damaged locations and house plants.

In addition, the following can be assessed:

  • Temperature
  • Humidity
  • Noise
  • Lighting
