The invention discloses a green, environment-friendly and energy-saving passive ventilation method suitable for a large building, which comprises the following steps of: (a) establishing a physical model: simulating indoor and outdoor wind environments of the large building in software, and in order to reduce the number of grids under the condition of not influencing a result, neglecting fine parts of the building during modeling, enabling the atrium space to be located in the middle, enabling the functional areas to be arranged around, and for the external environment, keeping the size of anexternal flow field area being 6-8 times that of a building; (b) setting boundary conditions; (c) establishing a mathematical model: carrying out discrete solution by adopting a reforming normalized group (RNG) k-Epsilon epsilon model; (d) researching the characteristics of the outer wall shutter; and (e) carrying out data simulation analysis: through comparison experiment data of multiple openingcombination schemes, taking the upper part of the atrium space as an exhaust port, taking a windward door as an air inlet, and promoting effective ventilation of each area of the whole building by matching with air exchange ports in multiple directions.
