Reasonable determination of indoor air quality controlled objective is an important prerequisite for solving indoor air pollution problem with multi-component and low concentration and building health and comfort indoor air environment.By combining pollution exposure conditions with human body metabolic pollutant and the pollutant emitting from building and furnishing material, the perceived indoor air quality controlled objective was studied for Chinese subjects on the basis of exposure experiments.Moreover, air quality acceptability and odor intensity were obtained by the subjects' votes.The results show that there exists obvious difference between visitors' requirement of indoor air quality controlled objective and that of occupants.in order to make 80% and 90% of the visitors satisfied, the required concentrations of carbon dioxide are 0.11% and 0.06%, required concentrations of total volatile organic compound are 243 μg/m3 and 76 μg/m3, and required per person outdoor airflow rates are 6.6 L/s and 19.5 L/s, respectively.Meanwhile, in order to make 80% and 90% of the occupants satisfied, required concentrations of carbon dioxide are 0.209% and 0.098%, required concentrations of total volatile organic compound are 583 μg/m3 and 228 μg/m3, and required per person outdoor airflow rates are 0.5 L/s and 14.1 L/s, respectively.
