New SG Design for extended service life

WG1/SGs Adaptability, Design for disassembly and re-use, and Repairability and maintenance were merged into a new SG Design for extended service life.

This new SG is coordinated by Lisa Ottenhaus (The University of Queensland, AU), Kristina Kröll (University of Wuppertal, DE), José Manuel Cabrero (Navarra University, ES), Robert Jockwer (Chalmers University, SE), and Rafael Passarelli (Hasselt University, BE).

The mailing lists of the merged SGs have been transferred to the new SG, so all SG members will be informed about further activities. The Miro board of SG Adaptability will be transferred to the new SG. A PhD group dealing with the topics of the SG is coordinated by Vera Öberg (Chalmers University, SE), Esther Vandamme (BE), and Lisa Kuiri (AU).

A SG meeting will be scheduled for early February 2024.

State of the art report (STAReport) published

The state of the art report (STAReport) is available for download here.

It includes 20 contributions from more than 20 experts on the topics of robustness, adaptability, design for disassembly and reuse, and repairability and maintenance in taller timber buildings.

This document allows the WG to better plan future activities and focus areas.

Thanks to all the authors who contributed the report!
