Abstract: In order to decrease the concentration of indoor pollutants, sorptive building materials have been used. Giving the construction materials themselves the property of reducing the concentration of indoor pollutants has been reported as simple and effective, because it is highly effective without requiring the operation of special equipment. Concentration reduction performance of indoor air pollutants by sorptive building materials depend significantly on air exchange rate, loading factor, mass transfer coefficients etc. In this study, we examined how the concentration of chemical compounds, temperature, and relative humidity influenced the sorptive performance for acetaldehyde, which was well reproduced experimentally with the computational fluid dynamics (CFD) simulations. The experiments and CFD analysis show that sorptive building materials have a fairly strong effect of decreasing acetaldehyde concentrations in rooms, and that this effect can be expected in practical use.
