In order to grasp ventilation performance in an actual house, the demand for simple and easy ventilation measurement method has been increased. In this report, precision of PFT method has been examined by comparison with three ventilation measurement methods. Two of them are PFT constant emission and CO_2 constant concentration method, which are called tracergas methods. The other is airflow measurement method. This time, PFT method is analyzed by the least-squares method with condition of non-negative constraint. In the first survey, PFT method and CO_2 method showed a good agreement. In the second survey, PFT method and airflow measurement showed a similar result value.
