In tills paper, a measuring method of the performance of passive adsorption building materials that are used for reducing pollutant concentration in a room is developed. The convective mass transfer characteristic has a great influence on its performance. In order to control the convective mass transfer rate precisely in the performance test, the authors have developed the Boundary Layer Type Small Test Chamber in which precise control of airflow along lhe test materials can be done. The equivalent ventilation rate (Q_<ads>) of adsorption performance is drawn as the new index that corresponds to the rate of convective mass transfer rate in the case of the adsorption surface concentration to be zero. To demonstrate the performance test, the adsorption test of the gypsum board that has the ability of decomposine HCHO within the board by the addition of some chemical materials is performed. The adsorption rate of the gypsum board prediated by the CFD corresponds well with the experimental result.
