FIELD MEASUREMENT OF NATURAL VENTILATION SYSTEM DESIGNED IN HOSPITAL BUILDING WITH VOID(Environmental Engineering)

Abstract

The energy-saving type building was designed and built. In the building natural ventilation is utilized. The route of ventilation was intended from the outer fagade to the courtyard fagade. After the building construction, an field measurement was performed to investigate the property of ventilation: air exchange rate, airflow distribution, visualization of airflow and pressure differentials between the outer and courtyard fagades. As a result, it was verified that the building design aim is realized enough.
