Abstract
To improve the thermal performance of Double Skin Facades (DSF) in warm climates, the risk of overheating in the system's cavity must be addressed. The use of wind-driven airflow as the dominant force for the heat dispersion from the cavity has not been studied from a passive ventilation performance point of view. For this purpose, a series of CFD simulations were conducted on two basic wind-induced DSF configurations considering four wind incident angles (0°, 30°, 60°, and 90°). Cavity air velocity, airflow pattern, and distribution, and the function of openings were assessed as essential measures of natural ventilation. The results demonstrate that the cavity air velocity and airflow rate of the openings in the DSF configuration with lateral openings (M0) are highly affected by wind direction while the application of a central front opening on external skin (M1) can moderate the dependency of the DSF on wind direction. The central opening, therefore, would encourage faster flow/higher flow rate inside the cavity when considering all directions which would increase the heat dissipation from the cavity. However, uneven air distribution in M1 facing 30° wind direction needs openings design improvement to meet the ventilation criteria
