An analysis on the potentials of Vertical Greenery System (VGS) in context to the application viewpoint

This review paper encapsulates the documentation on the application of Vertical Greenery Systems(VGS) in a sustainable development environment for urban society. With the information gathered from the reviewed literature, a number of key aspects regarding VGS, such as the classification of plantations by their Air Pollution Tolerance Index(APTI) systems, the climate influence on VGS and the different regulating system employed for the VGS have been explored. This technique uses vertical space for the growth of green cover. It will be beneficial for the cities having a high population density, where open space is scarce. In general, besides lowering the overall temperature, VGS has a great potential in minimizing the average consumption of energy in buildings, especially during summers. Furthermore, the review wraps up some aspects of VGS such as the species suitable for different climates, influence of orientation on energy saving levels, thickness of foliage, and composition of different layers and density of green cover on the walls.
