Window system is an essential component for ventilation, lighting, and thermal environment in buildings. However, window system has the lowest insulation performance and may cause high energy consumptions, if it is not properly designed. Thus, performance of window systems play an important role in built environment. This study proposes a new window systems for balcony, which has double vents and analyses the thermal performance using an intergrated simulation method with Therm 6.1 and Widow 6.1. The result shows higher U-factor than conventional window systems. It is expected that the double vent window system can increase thermal performance and save energy in apartment houses.
