Intended to welcome international experts from aerospace research and climatology this building consists of laboratories, a production plant, offices, as well as some housing. The birth of the first protagonist dedicated to the climate change in an urban environment implied to design a building new generation, emblematic of what it is possible to do in terms of bioclimatic architecture, with an approach by bio-mimicry. Our mission is based on a mathematical and generative open system made of algorithms ; our aim being to create an adaptable system that can be set in other geographic places, with an infinity of configurations for other future Climate Cities. This is a flexible system creating a structure that will follow uses and experimentations, not to constraint uses to a predefined envelop.
