An indoor air quality monitoring and assessment protocol for air-conditioned offices in subtropical climates

Brief:

The objectives of this study are to develop a practical IAQ monitoring and assessment protocol for promoting IAQ of air-conditioned offices in subtropical climates. The protocol presents IAQ assessment results with a simple IAQ benchmark, using the selected representative pollutant levels obtained from a number of alternative sampling schemes at acceptable assessment uncertainties regarding sampling locations and times. The development and feasibility of the protocol are demonstrated using a comprehensive cross-sectional survey on common indoor air parameters from a long-term measurement in air-conditioned offices of Hong Kong.
