A comprehensive modelling study was performed to determine volatile organic compounds (VOCs) emission factors in dry building materials. In order to examine the emission characteristics of VOCs in dry building materials (carpet), an experiment was conducted, and a mathematical methodology was considered together with a numerical work for a validation. Here, a new representative airside VOCs concentration was considered in a mode different from that of previous studies, which allows us to evaluate VOCs emission factors more accurately.
