PROBLEM TO BE SOLVED: To provide a natural ventilation method capable of completely drawing vapor (moisture) out of the whole inside of a building. SOLUTION: The natural ventilation method is so constituted that floor vent voids (f1) and (f2), ceiling vent voids (c1) and (c2) and a roof vent void (r) are largely distributed for opening to floor surfaces (1F) and (2F), ceiling surfaces (1C) and (2C) and a roof surface (R) so as to approximately become a value equivalent to a quantity of saturated vapor corresponding to mean temperature throughout the year in a construction area of the building even if area ratio for opening accounting for the whole floor area, ceiling area or roof area becomes small and that the whole inside of the building can be dried without being required for any forced ventilator even if partition walls for the arrangement of the rooms, fittings and windows are in a closed state by an upward ventilation airflow outward of the roof surface (R) from an underfloor space (S1).
