| Abstract |
The concentration of the pollutant in rooms depends not only on the emission and ventilation rates, but also on adsorption by the room surfaces. The use of sorptive building materials as room surface seems effective for decreasing the pollutant concentrations that have the possibility of affecting human health. In this paper, the effects of sorptive building materials with respect to decreasing aldehydes concentrations in air were evaluated using the small test chamber. Air containing a low concentration of aldehydes was supplied, and the decrease in aldehydes concentration was measured at the exhaust. We evaluated the performance for the aldehydes decreasing effect of kinds of sorptive building material. The formaldehyde-decomposing gypsum board had a more decreasing effect than any other sorptive building materials, which was well reproduced experimentally with the computational fluid dynamics (CFD) simulations. |
