For the moderns who spend more than 80% of the time inside a building, interior environment became important since it directly affects their health. Recently as noxiousness of the air contaminants of the interior space stood out as well as the above trend, the Ministry of Environment enacted a lawto maintain the interior air quality at certain level of standard in the multi use facility and newly constructed apartment. To make the indoor air clean, removal technology of various contaminants should be developed and interior materials with chemical treatment should be restrained. In other words, selection of interior finish affects indoor air quality from the initial design stage to the construction stage. However, only limited contaminants emission data of building materials are supplied by related companies. There is no average contaminants emission data for overall materials. Moreover, high cost and equipments for one time measurement of VOCs emission of interior finish are the obstacles of active research and data measurement. Therefore, this paper searched the current condition of average VOCs & HCHO emission of various interior finish based on the study requested to research center from the building material company through Stands Test Method for Indoor Air Quality.
