In many of today's modern
cities, urban planners and designers return to planting in built environments as an important strategy to
protect the environment, improve livable environments, and protect human
psychological and physical health. These organic systems, characterized by
green walls and green roofs; create a new type of living architecture within a modern architectural
understanding with inorganic and
inanimate structures. Green walls are sometimes called green facades, vertical
vegetation or vertical garden, living wall, or biological wall. In these
definitions, vegetation that grows directly on the façade of a building, or vegetation that grows on a
separate structural system that is freestanding and adjoining or partially
adjacent to the wall are stated. The benefits and
contributions of green walls to the environment at the urban and building scale
are quite a lot. While there is a green area border on
the ground at the urban scale, this area is more vertically. Considering these
benefits within the definition of ecological design and sustainability, it
becomes even more significant to evaluate green walls within today's design
criteria. In recent years, green walls in environmentally friendly
architectural structures have been used as an important design method to reduce
the negative effects of climate change and to clean the air. In this context,
green walls are an important building component that combines building and
nature. While the green shell of the building solves the environmental problems
of urban areas, it also keeps the users' connection with nature.
Today,
interest in remarkable green wall designs, which develop with the contribution
of developing technology and sustainability-oriented strategies, is increasing.
Many studies, both theoretical and experimental, are carried out on these
living green wall types, which aim to increase energy conservation, which is
one of the most important issues in the architectural field. In this context,
in the study; In ecological and sustainable design, the contribution of green
walls to the built environment is mentioned. The aim of the study is to draw
attention to the green wall systems that have been frequently applied in recent
years within the ecological and sustainable architectural design approach. In
addition, as a result of the study, construction details based on the existing
green wall examples in the world are presented in tables in order to create a
resource for the designers. In addition, information about the types,
application methods and techniques of such applications is given.
The study consists of two main parts. In the first part, a general literature review on vertical green wall systems and the effects of these systems on energy conservation has been made. Then, objective and subjective studies on energy efficiency research on green wall constructions with different properties and components were selected from the literature and examined. While determining the case studies, the articles that entered the relevant literature, whose originality was proven, and which were made between the years 2010-2020 were examined in detail. The data of the selected studies (climatic regions with green walls, plant species and systems used on the walls, layers of green wall constructions, experimental study results) are presented in tables under headings. The effect of green wall systems selected for each sample examined on building energy conservation and indoor thermal comfort has been evaluated comparatively. Environmental, economic and social advantages and disadvantages of these wall systems, which contribute to human health and happiness, are also included in the study. The result of the study has shown that these wall systems make great contributions to improving the indoor comfort conditions of buildings and reducing energy consumption. Also, it is anticipated that this study will lead to studies on the effectiveness of green wall constructions in the context of thermal comfort and energy conservation.
