About Introduction Principles of a Circular Economy Building and Construction Materials Design and Retrofit Regenerate Nature The Circular Built Environment A circular built environment will require action at every stage of the building and construction lifecycle. 1. MANUFACTURING Materials are manufactured locally using local skills and resources. Focus is placed on reducing all emissions and waste, using alternative, bio-based and renewable materials and reducing the dependence on mining and manufacturing of new materials. Manufacturers provide material passports for products, assemblies and fabricated elements which align with best practice guidelines and rethink business models to use less materials or adopting product take-back schemes. 2. DESI Holistic renewa emissio for ope of spac lifecycle materia < 7. REUSE AND RECYCLING End-of-life considerations are part of the full design process enabling opportunities for reuse and recycling. The value of recovered building products is fully understood, and upcycling opportunities are available. Buildings are deconstructed and the materials are reused again and again. 22 The Circular Built Environment Playbook 6. DECONSTRUCTION End-of-life considerations are part of the full design process enabling opportunities for disassembly and deconstruction. The value of recovered building products is fully understood, whereby buildings are deconstructed and building products are reused again and again.

Levers for Change Our Call to Action The Circular-Ready Checklist Glossary IGN c circular design approach makes use of passive design, able energy, water harvesting and local materials to mitigate ons and allow for regeneration of natural resources. Designing erational needs is considered upfront, focusing on the multi-use ces, design for flexibility, adaptability, disassembly and longer les. All materials including alternative, bio-based and renewable als are sustainably sourced and procured. 3. CONSTRUCTION Buildings are constructed to higher sustainability performance standards and modular elements in construction are used, making buildings easier to repair and maintain, disassemble and relocate or refurbish for reuse. Construction waste is eradicated as far as possible, whilst supporting improved quality and timelines for construction. 4. OPERATION Buildings are resource efficient and well maintained, enabling a longer life of buildings and their parts while reducing all waste and carbon emissions. Technology is used to enhance operational efficiency, and all materials that are part of existing assets are considered resources for the buildings of tomorrow. Building facilities are shared and contribute to the resilience of communities. < 5. RETROFIT All assets are retrofitted according to higher sustainability performance standards. Reuse is prioritised over demolition, and disassembly and deconstruction are a part of standard building practices. The majority of materials are locally sourced and procured which supports the economic resilience of the local community. 23
