Indoor air pollution with VOCs emitted from building materials causes serious IAQ problems. It is important to predict their emission rate from the building materials and to evaluate indoor concentration of VOCs. Mass diffusion process in porous media and the convective and diffusive transfer process in room air are fundamentals in estimating VOCs emission. In this paper the physical model of mass diffusion in porous media is derived and three macroscopic IAQ prediction models based on the model are proposed. Analyses of short-term emission rate of VOCs from materials and long-term prediction of indoor concentration are demonstrated with the IAQ prediction models proposed in this paper.
