Double-skin facade (DSF) is an additional glass skin on the outside wall of the building. In this study a mechanically ventilated and equipped with solar protections (venetian blinds) facade was studied. The airflow inside the facade as well as opening/closing degree of the blinds was controlled in order to increase annual energy performance for both heating and cooling. Numerical simulations for climatic data of Lyon (France) showed good performance of studied DSF compared to a traditional façade.

In the light of global environmental problems, it is vital for buildings to conserve energy and make use of natural energies. Natural ventilation is one important method for achieving this. In houses, natural ventilation is a very attractive way to control the indoor environment. Compared to this, mid- to high-rise buildings include many closed spaces where windows cannot be opened and internal heat is trapped inside, which increases the cooling load. Based on this situation, consciousness of environmentally friendly buildings and utilization of natural energy becomes high.
Increase in high-rise residential building has changed the envelope of residential building to aluminumcurtain wall which requires the use of the single-sided ventilation to be used instead of the crossventilation. It causes dissatisfaction mainly with indoor air velocity and ventilation volume. Therefore,the objective of this study is to improve the natural ventilation performance of high-rise residentialbuilding by opening design. To improve the natural ventilation performance in single skin faade, theeffect of different types of window will be evaluated.
