The investigation of the impacts of walls and green facades on the optimization of energy consumption in buildings and its role in a sustainable development

In recent decades, artificial environments, compared to the natural spaces in urban areas, are expanding day by day. Following the same trend in Iran, apartment living frame without any natural space has changed. And it is while the need to nature is still alive in human beings. Moreover, all over the world due to major problems such as global warming, air and water pollution, excessive energy consumption and its high economic costs, utilizing technologies of sustainable architecture and specially creating green buildings has got great importance. In this regard, the use of green areas can be used as appropriate strategy in order to solve existing problems and creating sustainable architecture. In this paper with research method based on library studies and descriptive analytic approach, green walls, to improve the energy consumption efficiency in buildings, have been investigated. And also the role of these systems in visual aesthetics of urban area in line with the objectives of sustainable development is examined. It seems that using green walls as a way to reduce the energy consumption in buildings can be an effective option to advance the goals of sustainable architecture.
