Abstract

As urbanization grows, the results become more visible. Heat islands are formed due to the loss of green spaces and the consequent disruptive effects of climate change, especially in densely populated urban areas. These phenomena threaten and endanger human health. One solution to compensate for the scarcity of urban green space today is to construct urban green space within the house's walls to provide a suitable and desirable space. Vertical greening systems have recently been recognized and tested by scholars as one of the most effective methods for reducing the harmful impact of heating on the environment. Due to the beauty of this solution, it has also been considered by architectural designers, and today we are witnessing a growing trend of green-covered buildings. In this regard, the number of manufacturing companies is expanding and considering that this solution is in its first steps of growth and there is a need for further study. So, the standard process makes it more functional. This research aims to study the actual process and design of green walls. As a result, at the outset of the journey, the market's current and usable systems should be defined and segmented, followed by analyzing the design and manufacturing process's strengths and limitations. Then, by examining the divisions produced among scientists and companies, the final classification has been presented and analyzed in this study in order to standardize the production process. It should be remembered that businesses from various European, Asian, Australian, and American countries were surveyed to ensure that gaps existed. Based on the current system's flaws, a new Vertical Greening Integrated Approach (VGIS) approach was introduced to make it more popular, economical, and functional. Developing countries like Iran have a significant share in increasing the earth's temperature. However, because of the high price of this nature-based, it is less welcomed and used more as a decorative component in luxury buildings. Therefore, Tehran's study sample, one of the leading centers of pollution and population density and buildings, has been selected. Finally, based on the new approach, the selected green wall simulated on residential building in Tehran. Results show that this strategy's effectiveness was to lower the surface temperature by direct green facade about 10.95 °C and via felt-based living wall 13.95°C.
