Abstract
Modern environmental problems are caused by increased energy consumption and the urban heat island effect. Urban noise pollution is another big problem in the Megacities. Ensuring safety with reducing hazards in the urban space is one of the priority tasks of the urban city centers. One solution is the use of green technologies in the construction of office and residential real estate. In this research, we provide the analysis of reducing the noise impact through the use of different green wall systems, such as modular, hydroponic and container, analyzing their benefits and disadvantages in terms of operation and maintenance. After that, we chose hydroponic systems as the most efficient ones and examined different conditions of the system and how these types reduce the noise analyzing absorption coefficient. As a result, we found out that the efficiency of the hydroponic green wall system depends on the humidity of the substrate and the presence of the plants, which confirms the importance of vegetation in reducing noise impact in urban environment.
