A passive stack ventilation system to control the ventilation rate was designed in an airtight test house and the ventilation rates were measured for five months in -winter. And the annual characteristics of the ventilation and the indoor air quality in houses with the passive ventilation systems were calculated by using a house model and the standard daily schedule models from NHK. The results were as follows. 1) The ventilation rates in the house with a passive ventilation system meet the ventilation requirement through the year with a fan controlled by an airflow speed sensor. 2) The ventilation rates change with the temperature differences between the inside and the outside. If the dwellers don't open windows to keep the indoor air quality, the ventilation rates were lower during the marginal season without the control system in houses 3) The energy demand levels to keep the ventilation rates using fans in the marginal season are low because the airflow ratio of the stack ventilation system is high. But the energy loss with the over ventilation rates in the coldest season are large, so the damper system is very necessary for saving energy.
