The Application of Green Wall Systems as a Passive Design Strategy in the Buildings of Hot Aired Areas

Abstract

Green walls are one of the environmentally sustainable and important passive design strategies in the building because of their high efficiency in reducing temperatures in the interior spaces and thus achieving thermal comfort for the occupants due to providing a high level of thermal insulation by taking advantage of the vegetation cover, which in turn contributes to achieving Comfortable indoor environment and then reduce the energy consumed for cooling and heating purposes and then achieve energy efficiency, as well as reducing the environmental impact in the vicinity of the building by reducing carbon emissions and pollution, and given the high temperatures in hot and dry areas, including Iraq, and the consumption of high amounts of electric energy by commercial buildings And because of the effectiveness of green walls in achieving energy performance efficiency in the internal environment of the building and in a passive manner, the research problem was determined by: Lack of knowledge about the mechanisms of applying green walls in the buildings of the Iraqi urban environment with a hot dry climate and their active role in achieving energy efficiency. The mechanisms of applying green walls in buildings, especially Iraq, which has a hot, dry climate, and then The most efficient green walls in achieving energy efficiency. The research included two aspects: the theoretical side, which dealt with the cognitive framework of green walls, reviewing its pros and cons, and indicating its effective role in achieving energy efficiency in commercial buildings, in addition to the restrictions of its application. And the practical side, which included the design of a commercial building. A virtual multi-storey building in Baghdad, with two models, the first with a traditional interface and the second with a green interface of the indirect type, and then measuring energy efficiency within the spaces of the two models by means of a computer program for environmental performance. The research found that the second model with an indirect green interface is highly effective in achieving Energy efficiency within the building spaces and in passive manner.
