Hybrid Reuse


Our strategy is to implant ourselves in what already exists. To reuse the existing context, while anticipating several future re-uses, several life cycles and not just one. It is for this reason that we have spoken of a hybrid strategy, combining upstream and downstream reuse To illustrate our point, we have chosen to implant ourselves in metallic buildings, such as halls, and warehouses, that are sensitive to the programmatic variations of a company and thus likely to be decommissioned. In this manner, they represent a strong potential for reuse. To address a multitude of life cycles, we have devised a “sliding” reuse strategy, increasing the life of the components tenfold by their reuse and especially by their hybridization with new materials and components. By allowing different uses of the same elements, we therefore extend the lifespan of buildings and offer flexible solutions over time, including details allowing adaptation to the existing. The current use of wood in the face of regulations imposes relatively short legal lifespan (Eurocode). To increase this lifespan, we propose a system that preserves the mechanical properties of wood as long as possible over the various life cycles. For its first cycle wood is used in forms such as LVL Kerto. In a second, third or umpteenth life, having gained momentum, the LVL module is offered 3 options: - simply turn the module over and benefit from a counter arrow - use the module vertically (partition or walls), changing its structural behavior. - be returned to local wood processing facilities for regularization (planing) and re-use with a lower thickness or to convert it to CLT. This last point, the reprocessing of LVL components in CLT, appears to us both innovative and relevant to generate optimum and complete cycles as well as supporting local businesses. Our proposal to use existing structures and perpetuating reuse allows this sliding system that we introduced to benefit from the latest technologies and, thus, be up to date. To conclude, we introduced a methodology rather than technical details, but this proposal makes it possible to extend (at least double or even triple) the life of the wooden elements and to make the most of hybridity, in an existing context which is ours, and which must be invested, by exploring the potentialities of its multiple lives.
