Abstract In 2011 The World Health Organisation named Lanzhou, the capital of the Gansu Province, China's most air polluted city 1. This is in part due to Lanzhou's geography, situated between two mountain ranges next to the Gobi desert, which results in large quantities of dust being blown into the city whilst the air remains trapped in the valley. It is also due to industry, an energy structure dependent on coal and heavy traffic within the city 2. However, heavy pollution is not an environmental issue solely isolated to Lanzhou but affects many of China's cities and others across the globe. During a month long field trip to the Lanzhou, China, as part of the Architecture and Extreme Environments masters program, a device was created that investigated whether algaes could be integrated within facade systems to absorb pollutants from the air 3. Algae was cultivated from water sources across Lanzhou and Lanzhou New Area (LNA) using a specially designed incubation unit and tested using a portable facade panel to see whether air pumped through these cultures had reduced levels of air pollution, both gas and particle. The following scientific paper documents the results and findings of these tests and is part of an ongoing endeavor at Architecture and Extreme Environments to investigate how architects and designers might rethink the built environment as a means to address these environmental issues. © 2017 Otis Sloan Brittain.
