Reduction of carbon dioxide by bio-façades for sustainable development of the environment
Hamidreza Rezazadeh,Zahra Salahshoor,Ferial Ahmadi,Farshad Nasrollahi 대한환경공학회 2022 Environmental Engineering Research Vol.27 No.2
Nowadays, air pollution and consequently global warming are the major problems that the earth is faced with. These issues can influence climate change and human health. Building façades can play a significant role in the air quality of the urban environment. Therefore, this study draws upon the ability of nature in controlling carbon dioxide to compare three types of bio-façades (i.e. Water façade, Green façade, and Microalgae façade) and to identify an appropriate one. For this purpose, we analyzed documents and scientific literature qualitatively. Then, we identified the aforementioned types of biological façades and selected the most optimal one through the comparison. Additionally, for this comparison, the analytical hierarchy process (AHP) method was employed that resulted in achieving the higher scores by the microalgae façade among other bio-façades mentioned above. The major criteria considered for the AHP analysis included climatic, economic, architectural, environmental, and structural aspects of using the noted bio-façades in buildings. It should be emphasized that the environmental aspect was obtained as the most influential criterion among others. Finally, some technical tips and design requirements for bioreactors are depicted and discussed along with their upcoming challenges and future research direction.

Use of double-glazed window as a photobioreactor for CO₂ removal from air
Hamidreza Rezazadeh,Maria Kordjamshidi,Ferial Ahmadi,Alireza Eskandarinejad 대한환경공학회 2021 Environmental Engineering Research Vol.26 No.2
The important issue of increasing CO₂ emissions to the atmosphere requires developing the environmentally sustainable strategies. One of the most innovative approaches in building design is using the microalgae photobioreactor (PBR) façades. In the current research, performance of a new green window was examined as an environmentally friendly method for the noted purpose. This window is a double-glazed window wherein the space enclosed by its two glasses was used as a PBR system. This window was investigated in two different conditions, namely as a window installed in a wall opening as a building façade element and also in laboratory condition. The experiments of the former condition were performed in Tehran city, where is known for the greatest air-polluted city in Iran, while tests of the later were carried out in Bablosar city located in northern Iran. Experiments include measuring absorption amounts of CO₂, temperature, optical density of cultivation medium, and evaporation. The obtained results validate performance of the proposed green window in decreasing CO₂ amounts. It was also observed that microalgae growth decreased the window transparency so that, in observing the general rules of Islamic and Iranian architecture, can enhance the visual privacy from non-mahram adjacent neighbors for Muslim women.
