Original Abstract

Ventilated façades help to protect buildings against overheating during the summer seasons. The efficiency of this function depends on many factors. The geometry of inlet and outlet openings may be the significant factor of the ventilated façade function. This study presents the experimental assessment of the outlet geometry influence on the temperatures and airflow in the open joint ventilated façade. Two sections with different outlet geometry are compared in the same time. Different types of outlet geometry are based on various window sill dimensions and various cross section dimensions between cladding and window sill. The cavity temperature and airflow differences are assessed during the direct insolation of façade sections. Results show that the effect of outlet opening area is much more significant than the assessed outlet geometry types.
