With the high air-tightness and ventilation deficiencies of modern residential and energyefficient buildings, countries in the world gradually emphasize that the well-controlled of Indoor Air Quality (IAQ) and Indoor Environment Health (IEH) would reduce the hazards of human health. This study is based on the international standard, ISO 16000-23 and ISO 16000-24, to establish a Sorptive Building Materials Test System (SBMTS) in Taiwan. This research collected three Green Building Materials Label (GBML) products, which are wood core board, wood fiberboard and latex paint, to investigate the "adsorption properties" test for each material in small-scale chamber with 0.2ppm formaldehyde for 72hrs. The result indicates, air samples shall be ensure that the inlet/outlet has the same air flow rate during air sampling of recovery test and the error and uncertainty would be decrease to 5%. The wood fiberboard has higher sorption "phenomenon" in this study, which formaldehyde sorption flux (Fm) is 210.47μg/m2· h, equivalent ventilation rate (Fv, eq) is 3.01m3/m 2·h, and average sorption rate is 70.89%. This study demonstrates the formaldehyde could indeed reduce formaldehyde under 0.08ppm (based on the guideline of WHO) during 168 hrs.
