Abstract

Vertical Greenery Systems (VGS) are self-sustaining garden systems that can be designed on the building envelope, they represent an innovative approach to rebalance the urban heat island phenomena that have become a major problem in recent times, resulting from urbanization and activities polluting the environment, especially in cities and urban with high density. These systems are becoming common and require further knowledge about their particular impacts on the building and the environment. In recent decades, various studies have been conducted to demonstrate that these systems can contribute to improving the urban environment and enhancing buildings' efficiency, though thermal research remains the most predominant subject compared to others. The latest technology of VGS systems reflects a sustainable approach to urban improvement and retrofitting buildings. Green infrastructure research is advancing regularly, recognizing aesthetic enhancements as well as ecological, economical, and social benefits. A board overview of vertical greenery systems and a thorough analysis of the basic advantages of these green infrastructures are presented in the paper. The purpose of this study is to investigate the influence of vertical greenery systems on the thermal building performance in the hot climate and to apply new methods to improve its efficiency. The paper discusses numerous VGS implementation case studies, reviewing the challenges and limitations of the usage of VGS in Egypt and the MENA region. Finally, proposing various guidelines for use of vertical gardens as an advanced technology for a sustainable urban approach.
