Aims Indoor air quality (IAQ) is one of the factors that determines the performance and maintenance of the building and affects the health and well-being of building users. The present study aimed at evaluating the breathing wall modeling to absorb indoor pollutants in the living room of a house inspired by the buffer zones of traditional architecture in hot and arid climate of Iran.
Materials & Methods The present descriptive study was carried out, using library method and computer modeling inspired by traditional Iranian architecture and sub-climate design of indoor climate and, as a result, the combination of pollutant adsorbent plants design in architectural space. Through ANSYS FLUENT 6.3.26 software, the effect of contaminated fluid release in the room space, as well as the concentration of the matter and its release were investigated by the snake plant with the boundary conditions. The air inlet was considered fixed at a speed of 0.5m/s, the output was considered relative constant pressure at zero atmospheres, and the walls were considered fixed with non-slip condition.
Findings The wind situation in the room was useful for diluting pollutants. The process of reducing the concentrations of pollutants was Suitable for the time, adequate, and appropriate by using plants.
Conclusion Based on wind condition modeling and the combination of pollutant adsorbent plants design in architectural space, plants contribute to dilution of pollutants, air conditioning, and deposition of suspended particles through the production of oxygen during photosynthesis and also the absorption of pollutants from the environment.
