A Summer Case Study on Applying Ventilated Double-Skin Facade to a Building in Cold Zone of China

Abstract

It is crucial for ventilated double-skin facade (DSF) compared to single- skin facade to avoid high energy consumption, optic pollution and inadequate ventilation problems. In this paper, the performance of ventilated DSF applied to a building located in a university in cold zone (Tianjin) of China is tested. The original conditions of both outdoor and indoor within each testing room are comparatively same.The temperature behaviors of both the ventilated air cavity of DSF and indoor space with different experimental modes during summer are investigated. Additionally, the effects on indoor temperature due to the ventilated DSF with different modes in summer are also analyzed. The results shows that the ventilated DSF is a effective approach to reduce indoor temperature; the opening airflow windows of external façade of the DSF should be effective to lower temperature of both the ventilated air cavity of DSF and indoor space.
