The conclusion of the case study was presented in the following points, • The best orientation of DSGF differs according to climatic conditions of each city. The west oriented DSGF was the best in Cairo and Aswan, while the east orientation was the best in Alexandria. • DSGF provided cooling effect to the office space by different values according to different climatic conditions. Generally, DSGF performance in Aswan was better than Cairo, and Alexandria provided less cooling effect than Cairo and Aswan. • The DSGF performance curve was not the same in 3 climatic zones. The maximum efficiency occurred in Cairo and Aswan was at 5 pm by 2.98oC and 3.62oC respectively. While the minimum performance of Cairo was at 9am, and 12pm in Aswan. For Alexandria, the maximum efficiency was at 11 am by 1.95oC, and its minimum value at 5pm. • As observed, the performance of the green façade was the maximum at high outside dry bulb temperature (from 2 to 5pm) in case of Cairo and Aswan. However, in Alexandria, the maximum efficiency of east DSGF was at morning (10-11 am). • Despite different densities of plant, DSGF was efficient in all cases, even if plant density was low.
