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