The purpose of this paper is to survey volatile organic compounds(VOC) and their emissions from building materials in residence. As a basic survey of VOC in residences, field measurements were carried out in 11 residences that were constructed 3-35 years ago. The effect of emissions from building materials on indoor was analyzed through the measurement in newly constructed residence. The results are as follows, 1) Total volatile organic compounds(TVOC) concentration in residences was ranged 95-590μg/m^3, 1.1-3 times as large as those of outdoor. 2) Alkans, aromatics, esters, alcohols and carboxylic acids were detected in residences. Compounds that were mainly detected in indoor were heptane, dodecane, toluene, ethyltoluene, dichlorobenzene. β-pinene and nonanal. 3) Nonane, decane, undecane, toluene, xylene and dichlorobenzene were emitted from flooring, ceiling and wall materials that were installed in model room. And it is found that emissions from building materials contributes significantly to indoor VOC concentration.
