PROBLEM TO BE SOLVED: To easily make an analysis of a smoke flow which is useful for the planning and designing of a pressure smokeproof system. SOLUTION: This smoke flow analysis system in a building which analyzes a smoke flow according to the fire state, door opening and closing, and air feeding and smoke discharge in the building is equipped with a library data file 2 which contains standard data including constitution elements and analytic conditions of a model as a library, a model drawing data file 3 which contains data of a model drawing, an input means 6 which inputs the respective constitution elements of the model and the analytic conditions by quoting the library on the model drawing, an analyzing means 12 which analyzes the smoke flow by using a two-layer zone model according to the inputted constitution elements of the model and analytic conditions, and an output means 7 which outputs the result of the smoke flow analysis; and the output means 7 outputs at least one of smoke diffusion level, smoke and air layer temperature, smoke layer height, a flow rate, and differential pressure as the result of the smoke flow analysis.
