Indoor Air Quality Audit and Grey Incidence Analysis of an Air-Conditioned Institutional Library in the Subtropics

Abstract:

The IAQ characteristics, both in terms of empirical objective measurements and subjective responses, are presented for an air-conditioned institutional library in subtropical climate. The objective measurements involve the measurement of physical parameters of the air dry bulb temperature, relative humidity, air velocity and the monitoring of the concentrations of selected chemical indicators of carbon dioxide, carbon monoxide, formaldehyde. The occupants' subjective sensation to IAQ is surveyed in terms of unacceptability. By calculating the relation degree between the subjective unacceptability and objective measurements with the grey incidence analysis method, the occupants' subjective sensation to IAQ is linked with the objective measured parameters and their relation is explored.
