Many sources of volatile organic compounds (VOC) including smoking, combustion and building materials have been identified in indoor environment from several studies. In this indoor VOC source, emissions from building materials have become current interests, and several methods to evaluate emissions from materials have been developed. Chamber test method is used to evaluate emission rate of compounds emitted from materials. But few have been made to comprehend the effect of environmental conditions on emission rates in chamber test. In this paper, emissions from three vinyl wallpapers and two gypsum boards were examined by several conditions of chamber. Compounds emitted from materials were analyzed and the influence on emissions rates by environmental conditions, such as temperature, relative humidity, ventilation rate and loading factor was evaluated. And it is found that emission rates of compounds are depended on environmental conditions, and the increasing of temperature, relative humidity and ventilation rate of the chamber accelerates emissions from the materials. Because the concentration difference of the chamber was not large under the experiment condition, the influence on emissions rates by loading factor could not be evaluated.
