In Japan VOC emission from building materials have become a major problem causing adverse health effects such as chemical sensitivity or symptoms related to sick building syndrome. However there was not enough data to confirm the efficient method to decrease indoor Formaldehyde and VOC concentration by selecting building materials. In this study we have made experiment to know the effects of furnishing materials on indoor Formaldehyde and VOC concentration using 3 similar experimental rooms. The experiments began from just before the construction and to 2 month after and have 3 different terms. Measurement in winter and summer were to test the effect of temperature to indoor concentration. We have also tested the efficiency of ventilation as mitigation for reducing indoor Formaldehyde and VOC concentration. Results showed that both Formaldehyde and TVOC concentration was highest after the interior structuring was constructed. Indoor Formaldehyde concentration was lower when the lower emitting building materials were used on both Formaldehyde and TVOC. However, temperature have effect more than the selection of materials. As for the effects of ventilation, opening the windows was most effective to decrease Formaldehyde and TVOC concentration. However, mechanical ventilation did not seem to be effective when the concentration was high, but when the concentration became lower when the concentrations has decreased.
