Indoor Air Quality


Monitoring of indoor air quality on a regular basis is useful for:

  • Ensuring that a building’s air quality is not deteriorating over time and thus allaying occupant concerns
  • To show that guide levels according to the Air Quality Standards are being maintained
  • To identify possible transitory problems

Measurements should be taken over a regular basis, including:

  • Air temperature
  • Relative humidity
  • Carbon dioxide concentration
  • Carbon monoxide concentration
  • Airborne bacterial and fungal levels
  • Formaldehyde concentration
  • Respirable suspended particles
  • Air turnover
  • Light level
  • Sound level
