Recently in Japan, high concentration of VOC caused by air-tightness in residences has become a social problem. There are many chamber tests of individual materials or measurements taken place in experimental residences. In real residences there are occupants. There is a possibility of them taking in sources of VOC, changing environmental conditions and etc., which will effect on the emission of VOC inside the residences. In this study we measured VOC concentration including formaldehyde in 50 residences. As a result, the mean concentration of HCHO and TVOC were 0.0478ppm and 3640μg/m^3 and the standard deviation were 0.0415ppm and 8240μg/m^3. The concentration differed 1.7 times with HCHO and 15 times with TVOC between new and old residences. In both HCHO and TVOC concentrations were higher in the winter time. There were no correlations between the temperature or relative humidity and the concentrations of HCHO or TVOC. The HCHO concentration became steady in about 6 years and TVOC concentration in about 8 years. Also it is neccessary to be aware of the product which the occupants bring inside the residences.
