Authors propose building components with a passive ventilation function called BAC (Breathing Architectural Component). It has an air infiltration function that can control the flow of heat, air and moisture. In this paper, from the viewpoint of the indoor thermal environment adjustment in the winter, the new indoor side position which adopts the device of natural ventilation function of BAC was proposed in order to reduce the outside inflow of low-temperature from reaching indoors. The performance evaluation on the room air-temperature distribution after inflowing the outside air to the inside of BAC and to the room was carried out based on the model of a full scale test house using numerical value airflow analysis under both steady and unsteady conditions. The result showed that the indoor air-temperature distribution and that the indoor cold stagnation disappeared in the low corner area of the room.
