/// System Summary [Heat-Pressure Lamination of PE-Foil] Used plastic shopping bags are the primary material for the system presented. They are made of low-density polyethylene (LDPE), come at low costs but also in small sizes and don't have good structural properties in the first place. Therefore multiple layers of PE-foil are laminated together by applying heat and pressure at the same time. From 20 layers onwards the material has board-like characteristics. To get a smooth material build-up a flat device for heat application and a flat working surface or mould is used. A modular moulding system that allows large tessellated formations and can be moved during fabrication facilitates the production of large, seamless structures with only a limited set of moulds. The size of the moulds determines the resolution of the pixelated geometry. Through the implementation of build-in cushions, three-dimensional structures are created from flat source material. Layers of non-adhesive material are placed between layers of PE-foil during lamination to create pockets, which are filled with concrete or granular materials – PU-foam was used for prototypes. With varying numbers of layers on each side, the PE-foil folds around the cushion while the pockets are filled, whereby the angle depends on the ratio of layers on the respective sides. Furthermore the cushions locally strengthen the structure since envelope and contents are one structural unit. The primary technique of heat-pressure lamination allows for ceating variable thickness throughout the construction, to weld it seamless into very large pieces in almost any direction and to integrate details by welding. /// Thesis Statement [Simulating, Optimising and Evaluating] The thesis focus lies not only on the development of a material system and its test applications but particularly in its testing and simulating both in the physical and digital realm. A physic-simulation, which incorporates material properties and abstracted simulations operating with surface folding allowed for the generation and evaluation of families of shapes. Local structural optimisation both in regards to geometry as well as in regards to material efficiency was achieved through interactive, parametric structural analysis. Both applications come with their respective range of geometric constrains and potentials. Using the modular moulding system any shape will be tessellated but can have almost every overall shape and can be theoretically seamless in any size. Using integrated cushions to generate form limits to geometry that can be produced though straight and curved folding of planar material and therefor to structures of medium size. /// Design Description [Recycling Eurotower] The Eurotower in Frankfurt provides the framework for an intervention with elements of intermediate scale, designed for a certain timespan. A spatial landscape - built from the described material-system with build in cushions - will facilitate an environment for co-working spaces, student- and other low-cost-housing as well as flexible event spaces. Considering the vast amount of vacant office space, it is assumed that the Eurotower will be unoccupied for a time span of at least five years after the European Central Bank (ECB) will move to its new premises in spring 2014. Taking the constant need for residential space in Frankfurt into account, it is proposed that the target users will move in to make temporary use of the building. As the users incrementally move in they will build their required spatial configurations and furniture at an in-house fabrication facility. The structures will provide areas for seating, bridge levels, partitions and enclosed spaces.+ More details
