Abstract
Many building materials with the chemical adsorption capability are widely used for the countermeasure against indoor air pollution. However, the performance evaluation method for them has not been established and the chemical adsorption performance on them is still unknown. In this study, we aimed at clarifying the adsorption capability of chemical substances on some building materials such as carbon adsorbent materials. The performance was expressed by the index of equivalent clean air rate or ECAR[m^3/h・m^2]. Results showed that the formaldehyde ECAR of plastered walls were ranged from 0.30 to 0.94 [m^3/h・m^2], the powdered plaster were 0.25 to 1.10 [m^3/h・m^2] and carbon adsorbent materials were 0.26 to 0.98 [m^3/h・m^2].
