Background: Considering global issues regarding energy challenges, climate change, and urban quality, vertical greening systems (VGS) are gaining increasing attentionin construction and planning studies. Consequently, VGS has become an integral component of the design for the building envelopes as a passive strategy for energy conservation in architectural components. This research aims to evaluate the shading and energy performance of VGS in buildings located in hot climate zones, while also optimizing VGS design as a structural feature, both externally and internally. This research was executed through simulations and field experiments conducted on a designed residential townhouse in Alamein City, Egypt. The objective of this research was to improve the evaluation approach for VG as elements of exterior and interior buildings, and VGS as an external shading device in Mediterranean climate .Methodology Incurrent research we are looking particularly on VGS concept, respectively VG used efficiently not only structural envelope but also like special element which can have an effect over energy consumption into building, according to the way how buildings is occupied. Standard configurations of green wall designwere evaluated in terms of their performance, thermal effects induced and daylighting though field observations. Also, a solution for realistic green walls was defined and implemented. The simulation and experimental results indicated that the air gap depth and leaf coverage ratio significantly affect theperformance of green wall system. The results indicated that sunscreens and shading systems, as natural perishable green walls, are very efficient. Taking under payment and green wall designs for hot climate such as those of Egypt would encourage architects use VGS as design element. Green walls seem to make indoor spaces more comfortable temperature-wise and improve natural light. This suggests some ways to think about putting these wall systems in different buildings. Methods: This research starts by looking at previous research on green wall systems and how they affect things like temperature, air quality, carbon dioxide, and other aspects. This Research also explores the benefits of green walls while examining the key design components required for effective green wall systems. It includes a case study from the Mediterranean region of Turkey to evaluate the performance of both indoor and outdoor green walls across different building types. Based on these findings, a design approach is developed and applied to residential projects, specifically townhouses in Alamein City. Furthermore, the research utilizes Revit and Design Builder software to analyze a townhouse model in Alamein City, Egypt, with the aim of assessing the impact of groundwater on heating and cooling loads, as well as CO₂ emissions, following a methodology like the Turkish case study.
