Claim Text:
1. An interior zone pressurizing method for lessening a stack effect problem in a building, the method comprising: checking pressure resistance performance of a dividing door, wherein the dividing door divides a floor of a plurality of floors of the building into an elevator hall and an interior section, wherein an elevator door separates the elevator hall from an elevator shaft extending between the plurality of floors, wherein the elevator hall is positioned between the interior section and the elevator shaft; determining a passing wind velocity by measuring the passing wind velocity between the elevator hall and the interior section of the building on a given one of the plurality of floors when the elevator door is opened; calculating a pressurizing degree of the interior section of a given one of the floors to be pressurized based on the checked pressure resistance performance and the passing wind velocity; calculating a supply air volume required for the pressurization and an exhaust air volume from the elevator shaft to an outdoor side based on the degree of the pressurization of the interior section of the given one of the floors; and pressurizing the interior section of the given one of the floors based on the supply air volume required for pressurizing the interior section and the exhaust air volume from the elevator shaft to the outdoor side while fixing a neutral zone.
