A TWO STEP MODEL FOR THE ASSESSMENT OF THE INDOOR AIR QUALITY

摘要

The improvement of the perceived air quality gains importance in the indoor environment of buildings and the vehicle industry. The aim is the identification of all odour relevant materials in interiors in order to guarantee a good air quality at low air exchange rates. In the literature different measuring methods around the odour intensity,the perceived air quality and the hedonic sensation of odours exists. A conversion of the different measurement results is only partly possible so that the results of different studies can be compared with each other only with difficulty. These difficulties handicap the application of the "perceived air quality" concept considerably in practice. The new two step approach for the assessment of the perceived air quality separates clearly intensity measurements of odours and acceptance methods and it shows a possible link of this two measurement methods.
