With The Clever Treefrog the IBA presents the first building worldwide with a bioreactor façade. This janiform passive house designed by the architectural practice SPLITTERWERK is setting the scene with its two red-white-red-white striped sunny-sided algae bioreactor façades. They consist of glass elements suffused with water, in which micro-algae are bred for the purposes of generating energy, for light control, and for providing shade for the building. The algae used as a biomass for generating energy grow on the façade of the residential building. The façade also changes colour with the continued growth of the algae and thus appears to be “in motion”.
From afar, you can already read two giant speech bubbles with black letters against a white background shown on the two green shady façades with their tiny windows, the first bubble asking “Photosynthesis?” and the second replying “Cool!”. Realisation also means communication.
