Abstract
The present invention provides a method for comprehensively assessing indoor environmental quality. Pollutant concentration data used in the method is an average value calculated after sampling is performed at a plurality of positions in an indoor space, and is therefore relatively accurate, so that an excessively high or excessively low pollutant concentration at a position is prevented from impairing the accuracy of a measurement result. In the method, concentrations of pollutants are further converted into damage values, the damage values of the pollutants are converted into a total damage value based on a predetermined rule, and an air index is then calculated according to the total damage value, where the calculated air index reflects the impact of various pollutants on air healthiness. Therefore, by using the method for comprehensively assessing indoor environmental quality of the present invention, the measurement is precise, and indoor air healthiness can be comprehensively reflected.
