Design concept for prefabricated elements from CDW timber for a circurlar building

Abstract

The EU funded project RE4 (REuse and REcycling of CDW materials and structures in energy efficient pREfabricated elements for building REfurbishment and construction) looks into opportunities for prefabricated, CDW timber elements (structural and non-structural) for circular buildings. Main goal is to minimise resource consumption for building construction but also waste generation related to building dismantling. An innovative design concept for a fully reversible, prefabricated, multi-story residential building from waste wood has been established that reflects robust but flexible and adaptable solutions to extend the buildings-life cycle. Reversible connections, reusable elements and recyclable materials shall minimise future waste generation, when such buildings reach their end of life. A prefabricated facade element manufactured for a two-story prototype shall deliver figures for easy installation, dismantling and future reuse. The study aims to show how current challenges can be overcome and design for disassembly can be promoted.
