Rationale for IAQ regulations in Scandinavia - similarities and differences -

This paper considers regulations and standards and compare them about their requirements in ventilation flow rates and IAQ. They can be a helpful tool to handle these requirements and to create buildings with a quality level which satisfies the needs of the users
Scandinavian countries are quite similar in respect of culture, building tradition, climate and so on. So, the difference in ventilation requirements between them should be expected to be small but the results of their comparison show a wide difference.
This can be explained by the uncertainties about IAQ and the necessary level of ventilation, in combination with different political views on the balance between energy use and IAQ.
