Abstract: Building fire zone modeling concept and its associated computer packages were studied and reviewed. A survey was carried out on various fire zone models available in the literature. Their limitations and needs of future development were identified. General features of selected zone models were highlighted. CFAST and FIRST were selected for detail evaluation and validation. Fundamental principles underlying in the basic predictive equations were reviewed. Algorithms and sub-models of major processes including the fire growth, combustion process and fire plumes were analyzed and discussed. Physical models previously developed for different fire phenomena, numerical techniques and algorithms which incorporated inside different fire zone models were reviewed and analyzed. Several systematic tests reported in the literature were used for comparing with the results predicted by the two selected models. Structural approach and techniques used for building fire zone models validation were reviewed. Both the qualitative (which refers to conceptual assumptions and ranges of applicability) and the quantitative (which refers to how well a model predicts the values of quantitative variables in a real case) aspects over different building fire zone models have been studied and compared in detail.
