Following the Hackathon Open Source Wood x FCBA challenge 2020 on reusability, Team 7 presents its building concept for a modular post and beam system. The main innovation is its connector system for non-load-bearing exterior walls. It aims to facilitate building for deconstruction by addressing a current knowledge gap in panelized, removable exterior walls. The suggested system uses prefabricated, closed exterior wall panels of standardized dimensions. This means the panels can be transported compactly, along with the other standardized construction elements (posts, beams, etc.) which facilitates offsite construction. The exterior walls' load is taken by the post and beam system through the connector and steel leg angle, and bolted aib the connector at the top. Combined with a post and beam system using few standardized connectors, this concept could help build highly evolutive, deconstructable buildings where components can easily be replaced, and building extensions are more easily planned. Looking forward, the concept could be pushed further through parametrization and mass customization, which would allow applying it to a wider variety of building archetypes.

Key benefit

Ecological values

Through offsite construction and the proposed connector concept, this building system promotes reducing construction and deconstruction (C&D) waste and allows replacing/reusing building components, including the building enclosure. The panelized enclosure detail is compatible with various types of insulation, including bio-sourced products, which could help enhance the environmental benefits of the concept.
