In profiling IAQ, full recognition is given to time as a dimension and the air-quality parameters to be measured are specified. Utilizing state-of-the-art technology in automatic air monitoring , data logging , computerization and information technology , IAQ profiling is quantitative and can be accurate, precise, labour saving and cost effective . Examples are given to illustrative that IAQ Profiles of air-conditioned indoor environments are reproducible from day to day and at different measurement points, which enables IAQ Profile to be used as a standard for communication and for indoor air management , controls and legislation . </li></ul>
