The Living walls as an Approach for a Healthy Urban Environment

AbstractSocieties are in a need for making a conscious choice to switch to a more sustainable way of life. Design, construction, and maintenance of buildings have a tremendous impact on the environment and the natural resources. All around the world, a huge amount of buildings are being constructed with many more to be done. The challenge will be to build them smart with a minimal usage of non-renewable energy, minimal production of pollution, and minimal cost of energy dollars. Other important issues in building include increasing the comfort, health, and safety of people who live and work in them. Indeed, buildings consume many of the natural resources and are responsible for many problems. Now, in the 21st century, people are slowly beginning to realize the necessity of green architecture where new aspects and technologies started to emerge in terms of green buildings such as green walls which are considered a new prospect for the phenomenon of urban heat island and energy conservation aspects [1,5].This research will display the meanings, the advantages and the techniques of the living wall as a part of the sustainable strategy for the urban environment. The Green vertical surfaces can contribute significant environmental, social and economic benefits to the built environment. moreover the research will display why this emerging technology should be considered as a valuable part of the design process for addressing climate change and energy crisis.The living wall could also function for urban agriculture, urban gardening, or for its beauty as art. It is sometimes built indoors to help alleviate sick building syndrome. Living walls are particularly suitable for cities, as they allow good use of available vertical surface areas. They are also suitable in arid areas, as the circulating water on a vertical wall is less likely to evaporate than in horizontal gardens.Finally, the research will conclude with several recommendations for the using of living walls technique which suits the arid climate as a part of sustainable strategy for the urban environment
