Traditionally the indoor contaminant distribution can be obtained by CFD methods. However, it is too time consuming and costly. This paper reports the development of a zonal approach as a simple model to provide an alternative and inexpensive approach for indoor contaminant distribution. Experimental measurements and CFD results are employed to validate the reliability of this method for direct problem. This comparison shows the capability of zonal method for solution of air flow in indoor environments. Finally, inverse zonal method is developed to predict the unknown indoor contaminant source location and strength (emission rate) knowing source release time. The inverse analysis for solving the identification problem is Levenberg-Marquardt method. The results show that this inverse analysis can identify the characteristics of a gaseous emission source using a zonal model as the direct problem.
