This façade system consists of stackable bio-reactors, which provide a large CO2-absorbing plant habitat. In addition to the primary purpose of CO2 absorption from the air, the system should also offer architectural added value in the form of façade greening. In addition, biomass is produced for further processing.
All in all, it was very important to me to develop a design principle that is both flexible and simple at the same time. In this way, the design can be easily integrated into existing situations and structures, while remaining cost-effective.
The primary design takes place through the core element and the structure of the water stairs. These stairs offer the swimming fern a living environment and growth area and are therefore the core of the bio-system of this concept. A certain amount of the swimming fern develops on the individual steps within each cycle and therefore this is also part of the design.
The design through the screens is only secondary and is strongly dependent on the building situation, the design of the building, possible restrictions - but above all on the wishes and ideas of the builder or customer. The flexibility of the panels offers the possibility to implement the system almost everywhere. All in all, this allows an infinite variety of design possibilities, shapes and structures.
Depending on the design, the panels can either be a concise part of the façade design and thus form the overall appearance of the building, or they can discreetly pick up the materiality of the existing façade and thus take a back seat in terms of design, or they can be unobtrusively integrated into the façade surface. Due to the very flexible construction method, which is also suitable for the existing building, the facade can be used over the entire surface, or even just accentuated clusters can be designed, such as stripes between windows.
This is an exemplary representation of the surface design. These designs serve as an outlook for various design possibilities depending on the respective situation and needs.
The construction as well as the fixing and manufacturing of the frames are based on conventional working methods from facade construction. Here I decided on a curtain-type rear-ventilated facade with a non-visible substructure. This is connected with comparatively little material or components and is therefore relatively light, flexible and also cost-effective.
