Controlling Air Pollution with the Use of Bio Facades (A solution to Control Air Pollution in Tehran)

Statement of the problem: The speed with which cities develop cause disruptions to the environment and create problems such as air pollution. Air pollution management programs are often focused on controlling the sources that are producing the pollutants. This method can effectively reduce the level of new air pollutants but it is does not have any effect on existing pollutants that are already in the air.
This paper, by accepting the current state is looking to control air pollution in order to reduce the level of harm to humans through architecture, municipal engineering, and the effect of facade structures. The capabilities that nature itself has in controlling air pollution have entered the field of architecture. Three of these capabilities will be studied: water facades, algae facades and green live facades. One of the most important approaches in architecture and municipal engineering is paying attention to nature as a model and solution to environmental problems. The main purpose of this research is to have a better understanding of how bio-based walls promote air quality and reduce pollutants and how to create a more productive bio-facade.
Research Because this research is interdisciplinary, combinative methods need to be used in order in undertake this research. The majority of the resources for this paper have been through libraries and available references; however, in order to further expand there is a need for combining the research from interdisciplinary fields. Because there is a lack of quantitative data about each system’s performance, the systems will be introduced through tables and their strengths and weaknesses will be identified. The research will then be applied to practical methods, which will allow for the qualitative comparison of these systems. The most productive method will be chosen. Based on all stages of this paper, and by considering the qualitative comparison of 3 bio-based facades and studying each system’s strengths and weaknesses, it should be acknowledged that green facades, can present a suitable structure for controlling Tehran’s air pollution. In regards to plans and predictions of Tehran’s municipality about beautification, it should be acknowledged that green facades have a higher chance for short-term productivity in solving this problem in the capital
