The W115 Commission has been renamed from Construction Material Stewardship to Achieving Circularity in the Built Environment, with the change officially approved by the CIB Board in May 2025. Two new joint coordinators, Professor Holger Wallbaum and Dr Maud Lanai, have joined the existing joint coordinator, Professor Tayyab Maqsood.
The Commission’s updated aims and objectives are available at:
https://cibworld.org/cib-commissions/w115-achieving-circularity-in-the-built-environment/
The Commission’s work is structured across six sub-programmes:
Subgroup 1: Sustainable Construction and Material Utilisation
Subgroup 2: Waste Management and Resource Transformation
Subgroup 3: DFMA and Offsite Construction
Subgroup 4: Adaptable Buildings and Lifecycle Management
Subgroup 5: Advanced Construction Technology Use
Subgroup 6: Governance for Circularity
As CIB is a partner of SBE2026, we would like to take this opportunity to present a progress update on W115’s activities, including an overview of research undertaken within each sub-programme. Additionally, we will extend an invitation for interested and relevant stakeholders to join the W115 Commission.
