Résumé

A full-scale house model was constructed in an artificial climate chamber, where cylinders were installed for simulating airflow paths, including cracks in the external and internal walls. The flow rate through the cylinders was determined by measuring the pressure difference across them. Ventilation behavior due to internal-external temperature difference, i.e. ventilation induced by buoyancy or stack pressure, was observed without using tracer gas. Parameters such as airtightness of the envelope, airflow resistance through the internal walls, which partly depended upon the operation (open or closed) of doors, and internal-external temperature difference were varied in a series of tests.
