LoginSource/sink models of volatile organic compound (VOC) emissions from building materials are reviewed and a multi-zone ventilation model is developed to predict concentrations of contaminants in rooms. The source model based on the principles of mass transfer and fluid flow presented by Zhang et al. (1995, 1996) is integrated into the multi-zone ventilation model. The characteristics of the parameters related to voc concentration, i.e. Schmidt number, ventilation rate and air velocity at the free stream are investigated by the sensitivity analysis. As a result of the simulation, voc concentration is decreased as the ventilation rate is increased, and the concentration is decreased as the Schmidt number is increased. However, the air velocity does not affect the concentration if the velocity is not low. In addition, a numerical example of multi-zone ventilation model is presented.
