双层玻璃幕墙作为新型的建筑外围护结构，对于建筑内部的采光、通风、隔热起着非常重要的作用。衡量双层玻璃幕墙通风性能最重要的两个指标是内部空气流动速度及热传导，利用CFD软件模拟得出与实际数据最吻合的电脑模型，利用这个标准电脑模型的参数，模拟得出不同几何尺寸的双层玻璃幕墙的这两项指标的图像及数据。进一步定量研究影响双层玻璃通风性能的关键几何因素，通过比较得出双层玻璃幕墙通风口及空腔大小对其通风性能的影响的一般规律，并以此来指导商业生产。

Demands for energy savings, thermal and visual comfort and a high-tech image for new building envelopes can be met with a Double Skin Fa ade (DSF). DSF is crucial to interior lighting, venti-lation and insulation. The internal ventilation air flow rate and thermal conductivity are important indicators for measuring ventilation performance of DSF. Parameters of model derived from Computational Fluid Dy-namics (CFD) are utilized to simulate and form images and data of ventilation rate and thermal conductivity for DSF of different geometries. Key geometric factors affecting DSF ventilation are analyzed quantitatively. General condition of ventilation opening and cavity size are expounded. The validations of the results are based on experimental data from the literature.
