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.
Whether it be Mies van der Rohe’s flowing space, Frank Lloyd Wright’s open floor plan, or Adolf Loos’s Raumplan, not to mention Margarete Schütte-Lihotzky’s economical Frankfurt Kitchen – their contemporary development is incorporated in the intelligent residential typologies of the Case Study House Clever Treefrog. In the adjustable structure of these new residential typologies, functional spaces can be alternately or simultaneously attached or detached on demand. The Loos plan thus becomes an individual and time-oriented living plan. The appearance of living space is dominated by user-oriented living requirements and changes of programme. Accordingly, Smart Spaces develop from the Milan Apartment with different typologies of reconfigurable floor plans.
Multiincident Shells are switchable structures that are enriched with events. The Hamburg Apartmentin the Clever Treefrog is a Multiincident Shell which is informed by the functions and programs of dwelling. The area of this apartment is limited to 64 m²; of this area, 46 m² are a functionally neutral zone. The remaining 18 m² are filled with specific, domestic functions; each of these functions can be individually activated and separately extended into the neutral zone. In this way, it is possible to arrange the hall, the kitchen, the dining space and the living room, each of which is 46 m². Seen in this way, the space of many times 46 m² is the equivalent of a 368 m² apartment.
