Predicting airflow in naturally ventilated double-skin facades: theoretical analysis and modelling

Abstract

Naturally ventilated double skin façade (NVDSF) utilizes solar radiation to introduce natural ventilation through a double-skin façade cavity with vents. It is an easy-to-implement green technology that can be widely applied to new or existing buildings. However, its implementation in buildings is still limited as the coupled radiation and natural convection pose challenges in predicting ventilation performance. Moreover, the diversity of real-life applications raises a great need for a universally applicable method that can account for realistic design factors. Hence, an in-depth theoretical analysis model is required to facilitate the application of NVDSFs in buildings. This study proposes..
