Ventilation is the action of removing dirty indoor air and replacing with fresh outdoor air.

Poor air quality can be attributed to many problems arising in the workplace or in the home.  It is believed to contribute to a significant loss in productivity, low morale and higher rates of sickness amongst many employees.

Due to countermeasures for formaldehyde and other causes of sick building syndrome, the line of thinking regarding ventilation in rooms has changed. In July 2003 the amended Building Standards Law was enacted.

Building Standards Law

The viewpoint regarding ventilation for people varies according to the building construction.

If the area of window or opening that provides ventilation is at least 1/20 of living-space floor area then natural ventilation through an open window or opening will suffice.

If the area of window or opening that provides ventilation is less than 1/20 of living-space floor area or  the area is a designated building (such as a playhouse, movie theatre, performance hall, auditorium, public hall, or assembly hall) the mechanical ventilation is required at the recommended ventilation rates.

Sick Building Syndrome

Sick building syndrome (SBS) is where people in particular work or office environments have a range of non-specific, building-related symptoms.

SBS symptoms

The symptoms of SBS may include:

  • headaches
  • dizziness
  • nausea (feeling sick)
  • aches and pains
  • fatigue (extreme tiredness)
  • loss of concentration
  • shortness of breath
  • sensitivity to odours
  • eye, nose and throat irritation
  • skin irritation (skin rashes, dry itchy skin)

The symptoms of SBS can appear on their own or in combination with each other. They usually improve or disappear altogether after leaving the building.
