The work environment and indoor climate

The indoor climate and air quality are affected by a number of factors:

  • Ventilation
  • Temperature
  • Air humidity and velocity (drafts)
  • The quality of the air we breathe (gases, steam, perfumes, etc.)
  • Particles from living organisms (pollen, bacteria, viruses, mould, algae etc.)
  • Particles from dead biological or inorganic materials (dead mould, skin peelings, dirt, traffic dust, etc.)
  • Static electricity

Our ability to individually control the air temperature and the orderliness and cleanliness of our workplace also affect our perception of the indoor climate.

Health and the indoor climate

Most people are not affected by a normal indoor climate. Any individual who experiences symptoms will usually find that they surface after a period of time, increase over the course of the day and decrease when the person has left the premises. Sensitivity to these symptoms varies greatly from individual to individual. The experience of discomfort is affected by several factors.

Symptoms that can be related to the indoor climate:

  • Headaches.
  • Skin irritation.
  • Mucosal irritation of eyes, nose and throat.
  • Respiratory ailments such as asthma or frequent respiratory infections.
  • Fatigue or tiredness that might lead to difficulties concentrating.

Get a better indoor climate

Temperature, an orderly office and good cleaning procedures are important in creating a good indoor climate. A thorough cleaning of the entire office should be conducted once a year. If these measures are insufficient, you should report the problem to the unit manager. You may report the problem through the safety representative  or the Work Environment Committee (in Norwegian).

You may also contact the building manager  and/or the Occupational Health Service (in Norwegian). Measures that can be taken after consultation with these include:
