N2 - 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.
