Ventilation airflow rate of the occupied houses in the northern region of Japan is the subject of that study. The investigation consisted in the measurement of the ventilation rate using three different methods : the constant concentration method, airflow measurement at inlet/outlet and PFT method.
This paper presents the results of the constant concentration method, obtained with a B&K 1302 multi gas monitor and two B&K 1303 multipoint samplers and dosers., An example for the improvement of the ventilation by increasing the ventilation rate is also presented.
