Outline of Final Research Achievements

We studied natural ventilation that contributes to energy saving and good indoor environment. In particular, recently, we investigated the changes of natural ventilation air volume and the indoor thermal environment for double skins, which are increasingly adopted for environmentally friendly buildings, when used in combination with wind induced ventilation. In addition, we investigated the airflow distribution in the room when the wind catcher is installed in double skin. As a result, it was found that when the wind induced ventilation door is installed in the double skin, the comfort of the room increases. Also, it was found that the natural ventilation air volume in the double skin also increased. It also showed that the indoor airflow speed increases by installing the wind catcher in the double skin. Finally, by installing the wind catcher in the double skin, the efficiency of converting the wind speed near the wall surface to the wind pressure is also shown.
