Building windows are a dominant source of thermal energy loss, possessing significantly lower heat transfer resistance than insulated wall structures. Enhancing the energy efficiency of window systems is possible by integrating them into the building's ventilation scheme. Ventilated windows facilitate the controlled intake of external fresh air or the extraction of internal exhaust air, enabling partial heat recovery and tempering of the airflow. However, this air movement increases dissipative heat loss through the glass surfaces, necessitating an efficiency study. This research evaluates the effectiveness of ventilated windows by comparing the recovered thermal energy against these additional dissipative losses. The study is conducted via numerical modeling of coupled air flow and heat transfer within the window structure. A finite difference method is employed to solve the governing system of equations, which includes the continuity, momentum, and energy transfer equations for the air, as well as the heat conduction equation for the glass. The numerical results consistently demonstrate that the heat saved through pre-heating incoming air or recovering heat from exhaust air is greater than the additional dissipative heat loss through the glass. Therefore, the implementation of ventilated windows is confirmed to be an effective solution from an energy efficiency perspective.
