摘要

尽管nvdsf具有节能潜力，但本研究通过优化其几何结构来检验双层幕墙（DSF）系统的有效性，以增强办公大楼的自然通风和室内空气质量。使用grasshopper软件中的Butterfly插件，将DSF系统的性能与约旦安曼没有DSF的基本情况进行了比较。根据美国供暖、制冷和空调工程师协会（ASHRAE 62）的标准，拟议的方案证明了室内空气质量的改善，将实际通风比提高到5.3，而基本情况为3.75。此外，确定了最低速度的位置，并分析了高湍流区域，以优化空间利用。最重要的定性结果是，房间的角落，特别是靠近入口和出口的提议开口，被发现是一个高湍流，不太容易被用户接受。

Optimizing airflow in double-skin facades: Influence of vents design and cavity depth

Despite the energy-saving potential of NVDSFs, this research examined the effectiveness of the Double-Skin Facade (DSF) system by optimizing its geometric configurations to enhance natural ventilation and indoor air quality in office buildings. Using Butterfly plugin inside grasshopper software, compared the performance of the DSF system to a base case without DSF in Amman, Jordan. The proposed scenarios demonstrated improvements in indoor air quality, increasing the actual-to-required ventilation ratio to 5.3, compared to 3.75 in the base case, according to American Society of Heating, Refrigerating, and Air-Conditioning Engineers) (ASHRAE 62) standards. Furthermore, identified locations with the lowest velocities and analyzed high-turbulence areas to optimize space use. The most important qualitative results were found that room corners, particularly near the inlet and outlet proposed openings, were found to be a high turbulence and were less acceptable to users.
