A study on the characteristics and reduction of pollutant emission by finishing with natural materials for improving the IAQ

This study aims to reduce the pollutant emission for improving the IAQ by finishing with natural materials. To investigate the concentration of pollutants such as Vocs, HCHO, both the chamber experiment and field measurement were conducted. The results of the study can be summarized as flows. (1) According to the chamber experiment of pollutant-emitting porwer of diatomite materials showed that VOCs and formaldehyde emission rates were lower and satisfied to the most on the HB Grade. (2) The field measurement of pollutant-emitting concentration of clay materials were lower 35% than other materials. (3) The Vocs and formaldehyde were most emitted from furnitures and the emission rate were found to be proportional to indoor air temperature. To control the emitted pollutants efficiently, the reasonable selection of finishing with natural materials are required.
