ISO 20887:2020 is an international standard titled “Sustainability in buildings and civil engineering works — Design for disassembly and adaptability — Principles, requirements and guidance.” It provides a framework for integrating Design for Disassembly and Adaptability (DfD/A) into construction projects to enhance sustainability, circularity, and long-term value.
Design for Disassembly (DfD):
Enables safe, efficient removal of components at end-of-life or for reuse
Encourages use of materials and joints that allow easy separation
Supports selective demolition and material recovery
Design for Adaptability (DfA):
Facilitates future modifications, expansions, or repurposing
Reduces need for demolition and new construction
Enhances building resilience and lifecycle performance
ISO 20887 applies to:
All building types (residential, commercial, industrial, institutional)
Civil engineering works (bridges, roads, pipelines, etc.)
New construction, renovation, and refurbishment
It’s used by:
Architects, engineers, and designers
Developers and building owners
Regulators and sustainability certifiers
In Italy, ISO 20887 is referenced in the Criteri Ambientali Minimi (CAM) for public procurement. Projects must demonstrate disassemblability and selective demolition aligned with ISO 20887 to qualify for green building incentives and circular economy goals.
Under the EU Carbon Removal Certification Framework (CRCF), product-based carbon storage (e.g., in buildings) must show long-term durability—ISO 20887 helps validate that through its DfD/A principles.
