Investigation of the roof and vertical green structures and a sample application to Erbil

Urban development is causing environmental and social worries that are makes a risk to human welfare and the sustainability of cities. The new green architecture concepts are being developed to decrease problems by a sustainable and natural way. Roof and vertical greening systems can be defined as structures that allow vegetation to spread over a building or facade or interior wall. These systems are becoming popular with evolving slowly, and acknowledgement on some of their special impacts is required. In the last five years, the number of studies published in the scientific literature on this topic, especially involving living roof and living walls, has significantly increased. This scientific interest has corresponded with an increased and parallel attention by the general public. This scientific interest has agreed with an increased and parallel attention by the general public. This work offers a broad description of the different systems and a thorough review of the special benefits of these green infrastructures. Additionally, this study was designed a sample simulation to a part of Erbil city on living roofs and vertical gardens.Keywords: Bio mimicry, Built environments, Energy conservation, Green roof, Living walls, Sustainable construction, Urban ecology, Urban greening
