Full-scale chamber of test house was used to investigate emission data of terpenes from cypress wood and pine wood. This experiment involved placing samples of the specimens and an ozone generator in one room of the test house. The major terpene emitted from the specimens was pinene<alpha->. The indoor concentration of pinene<alpha-> with ozone emission was much lower than that without ozone emission. It was found that the higher the indoor ozone concentration, the lower the concentration of pinene<alpha->. The pinene<alpha-> might have been consumed by the reaction with ozone during the experiment. The concentrations of acetaldehyde were not changed regardless of the change of ozone concentration for both specimens. On the other hand, the concentration of formaldehyde with high emission of ozone was fairly higher than that without ozone emission for the specimen of cypress wood.
