Abstract [en]

Measuring deconstructability and reusability of timber buildings. Timber construction must - like all construction - develop towards better resource management. One way to reduce raw material consumption and waste production may be to reuse buildings and building components to a greater extent, and to facilitate this, buildings would need to be designed with that aspect in mind. A European project, InFutUReWood, has investigated how design adapted for reuse can be facilitated and has identified a need for a tool for assessing the deconstructability and reusability of timber buildings. A basic first sketch for an assessment tool was produced, and this study takes the work with the tool further. The overall purpose is to support a development where reuse is considered already in the design phase. More specifically, the project develops a tool to assess how well deconstruction and reuse have been considered in the design of a timber building. The tool is based on the international standard ISO 20887: 2020 and on case studies. The project seeks to answer the questions: What makes deconstruction and reuse easy and what makes it difficult - according to case studies? How can these experiences be considered in the design of the assessment tool? What development needs are there for the sketch of at tool? The work has three thematic parts: 1) Analysis of dismantling and reuse processes in case studies. 2) Analysis of an existing draft of a tool. 3) Assessment of how the tool could be further developed. The general methods of the work are result analysis, interviews, photo documentation and studies of drawings and construction documents. The case studies show several practical ways to achieve dismantling and reusability and illustrate how ISO 20887:2020 can be practically applied. To make the tool suitable for use by an independent party, it needs to be simplified and the assessment criteria processed to be more objective. Clues to how the indicators can be developed are obtained. Continued work includes the involvement of industry to develop criteria that will make them have confidence in the tool. A reformulation and new formulation of indicators in the tool and validation of these is also needed.
