CROSS-REFERENCE TO RELATED APPLICATION [0001] This application is a Divisional of co-pending application Ser. No. 11/147,431 filed on Jun. 8, 2005, and for which priority is claimed under 35 U.S.C. .sctn.120; and this application claims priority of Application No. P2005-0012316 filed in Korea on Feb. 15, 2005 under 35 U.S.C. .sctn. 119; the entire contents of all are hereby incorporated by reference. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to ventilating systems, and more particularly, to a ventilating system for introducing outdoor air and discharging room air, and a method for controlling the same. [0004] 2. Discussion of the Related Art [0005] A ventilating system is provided to a general house or an apartment for ventilating rooms. Such a ventilating system is provided with a duct that forms a moving passage of air. The ventilating system is provided with, in general, an air supply fan and an air discharge fan, and the duct is, in general, provided with an air supply duct and an air discharge duct. In operation, when the air supply fan is driven, outdoor air is supplied to the room through the air supply duct, and when the air discharge fan is driven, the room air is discharged to an outside of the room, thereby ventilating the room. [0006] In the meantime, in case of a new building, there are much Volatile Organic Compounds (VOC), such as formaldehyde, emitted from various construction materials. It is known that such volatile organic compounds cause dermatitis, and cancer. In a case there are much volatile organic compounds in the room, it is required to ventilate the room, quickly. [0007] However, sizes of the air supply, and discharge ducts, and outputs of the air supply fan and the air discharge fan are fixed already, an amount of outdoor air supplyable in a unit time period, and an amount of room air dischargeable to an outside of the room in a unit time period, are limited. Therefore, in a case the room air is polluted heavily, the room can not be ventilated, quickly. In order to solve such a problem, it is required to design the air supply, and the air discharge ducts larger, and provide larger capacity air supply fan, and air discharge fan. However, in this case bulky ventilating system and ducts impedes easy mounting thereof. SUMMARY OF THE INVENTION [0008] Accordingly, the present invention is directed to a ventilating system, and a method for controlling the same that substantially obviates one or more problems due to limitations and disadvantages of the related art. [0009] An object of the present invention is to provide a ventilating system, and a method for controlling the same, which can ventilate a room when the room is polluted heavily. [0010] Another object of the present invention is to provide a ventilating system for introducing outdoor air and discharging room air, and a method for controlling the same, which can ventilate a room taking a content of volatile organic compounds of room air into account. [0011] A further object of the present invention is to provide a ventilating system, and a method for controlling the same, which can improve a ventilating capability of the ventilating system without providing larger ventilating system and ducts. [0012] Additional advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention. The objectives and other advantages of the invention may be realized and attained by the structure particularly pointed out in the written description and claims hereof as well as the appended drawings. [0013] To achieve these objects and other advantages and in accordance with the purpose of the invention, as embodied and broadly described herein, a ventilating system includes a duct for making a room and an outside of the room in communication, a ventilator connected to the duct for discharging room air to an outside of the room, and supplying outdoor air to the room through the duct, a window controller provided to each window for opening/closing the window individually, and a controller for controlling the ventilator and the window controller for ventilating the room. [0014] The ventilating system may further include a VOC sensor for measuring a content of volatile organic compounds of the room air. The ventilating system may further include sensors for measuring conditions of outdoor air and room air. The sensors include a room temperature sensor for measuring a temperature of the room air, a room humidity sensor for measuring humidity of the room air, an outdoor temperature sensor for measuring a temperature of the outdoor air, and an outdoor humidity sensor for measuring humidity of the outdoor air. [0015] The window controller includes a control unit for opening/closing the window, and a driving unit connected to the control unit for generating a driving force. [0016] The window controller makes the window to slide sideways to open/close the window. In this case, the control unit includes a housing connected to the window, the housing having a helical hole, and an elongated screw coupled to the driving unit and placed in the helical hole for moving the window connected to the housing as the screw is rotated by the driving unit. The driving unit may include a driving motor coupled to the screw with a shaft, or a gear box connected to one end of the screw, and a driving motor coupled to the gear box with a shaft. [0017] The window controller pushes/pulls the window forward/backward to open/close the window. In this case, the control unit includes a driven gear connected to the window, and a driving gear connected to the driving unit, and engaged with the driven gear, for being rotated by the driving unit to rotate the driven gear, for opening/closing the window. The driven gear is coupled to the rotating shaft of the window with a shaft, and the driving unit includes a driving motor coupled to the driving gear with a shaft. [0018] The controller determines a ventilating method and a ventilating rate taking the content of volatile organic compounds of the room air, and controls the ventilator and the window controller, accordingly. The controller closes the window when the room air is polluted lower than a preset highest reference value. [0019] The controller determines the ventilating method and the ventilating rate taking the outdoor temperature into account additionally when the room air is polluted higher than a preset highest reference value, and controls the ventilator and the window controller, accordingly. The controller closes the window, and puts the ventilator into operation, for ventilating the room, if the outdoor temperature is outside of a present range. [0020] The controller determines the ventilating method and the ventilating rate taking a temperature difference between the room and outside of the room if the outdoor temperature is within a preset range, and controls the ventilator and the window controller. The controller opens the window to ventilate the room if the temperature difference between the room and outside of the room is within a preset range. The controller closes the window and puts the ventilator into operation, for ventilating the room, if the temperature difference between the room and the outside of the room is outside of the preset range. [0021] In the meantime, in another aspect of the present invention, a method for controlling a ventilating system includes the steps of measuring conditions of room air and outdoor air, determining a ventilating method and a ventilating rate according to the measured conditions, and ventilating the room by opening/closing at least one window automatically, and putting a ventilator into operation according to a result of determination.
