Indoor Air Quality

The quality of our indoor working environment is influenced by three major factors:

  • Air Pollutants – gases, dust, particles, biological sources
  • Physical Factors – temperature, humidity, noise, ventilation, lighting
  • Building Construction – air conditioning, occupancy rates, materials

Indoor Air Quality must be of a sufficient approved standard to ensure the adequate protection of human health and well-being.

Indoor air is defined as any non-industrial indoor space where a person spends a period of an hour or more in any day and can include the office, classroom, motor vehicle, shopping centre, hospital and home.
