| Abstract |
There is an urgent need for construction systems that enable the recovery of materials at the end of a building's life. The current widespread use of adhesive-based fixings and single-life materials formed from petrochemical derivatives has led to the unprecedented generation of toxic material waste. Consequently, up to 40% of global waste is estimated to come from the construction sector. This design-led research study examines the potential of new light timber frame designs to facilitate material recovery. The research focuses the geometric and jointing properties of the components within the light timber frame and their potential for reuse. To validate the success of the proposed design ideas, a lifecycle assessment of the product was undertaken. This has been supported by a detailed discussion of the durability performance of the system. The study finds that the geometric and assembly conditions of the frame significantly increase long-term sustainable measures. The proposed design is estimated to represent a 70% reduction in embodied energy over an extended product's lifetime versus conventional light timber platform framing. |
