Takeshi Aoi completed his master's degree in Sanitary Engineering at Kanto Gakuin University in 2007 and subsequently joined Nikken Sekkei. He has since been involved in mechanical engineering for a variety of projects, including offices, commercial buildings, hotels, research centers, and sports complexes. In the field of research centers, he has worked on facilities with highly specialized requirements, such as animal experimentation labs and nanomaterial research labs at the National Institute of Health Sciences, the BSL-4 lab at the National Research Center for the Control and Prevention of Infectious Diseases at Nagasaki University, and the ultra-low concentration chemical clean rooms at the Kurita Innovation Hub. Additionally, as an expert in sanitary equipment, he is actively engaged in creating environmentally sustainable buildings that embrace the Zero Water Building concept, which focuses on the efficient use of water.

He is also a member of the Architectural Institute of Japan’s Subcommittee on Zero Water Building Modeling and the Committee on Plumbing and Drainage Systems Research. He holds qualifications as a first-class architect in mechanical engineering, a CASBEE building assessor, and a CASBEE Wellness Office assessor.
