By far more and more attention has been paid to indoor air quality(IAQ). Excellent indoor air ensures health of occupants. It has become a worldwide problem and caused many sick building syndromes(SBS) and building related illness(BRI), which can not be ignored. Indoor air quality would be one of the most important problems which developers, owners, proprietors care more about before ing 21 stcentury.But up to now, due to lack of accepted international specific standard and uniform method of assessment on indoor air quality, in many cases, some index and standards in assessment on outdoor atmosphere have to be employedwhenassessing indoor air quality. Stressing on this point, a new assessment system, based on fuzzy mathematics, is put forward in this paper. A full-scale assessment on indoor air quality of 6 high-rise buildings in Shanghai is carried through. All data are from measurement on site. 1.INTRODUCTIONThe re are thousands of pollutants in building. We can not measure every pollutant that can impat occupant health and comfort, but we can select some representative pollutants as indicator for different sort of indoor contamination. The indicator and its reference value can provide a broad assessment of IAQ. The reasons for selecting indicators and their
