DEVELOPMENT OF VENTILATION MEASUREMENT METHOD USING HUMAN EXPIRATION - EXPERIMENTAL STUDY FOR ESTIMATION ACCURACY -

Investigation of ventilation measurement method was carried out in a full-scale test house. The aim ofthis study was to examine the ventilation rate via human expiration. The adopted method is able tomeasure multi-zone airflow rates. Airflow rate between rooms was monitored and the outdoor airflowrate was measured by using the constant concentration tracer gases. The rate of outdoor airflowentering the house and the airflow rate between the rooms were estimated by the ventilationmeasurement method via human expiration based on system identification theory. The estimatedresults were compared with the measurement results in order to validate its accuracy.
