Circularity in the Built Environment 2024

Implementing circularity in retrofits will be largely influenced by reuse and recycling infrastructure, capabilities and knowledge of circular practices, regulatory frameworks, materials used and commitment to sustainability (Figure 6). The quality of the building stock and the evolution of cities are also crucial considerations. In the near future, circular retrofits – and retrofits in general – are likely to be concentrated in Europe, North America, parts of the Asia-Pacific, and metropolitan areas in the Middle East, Africa and Latin America.To effectively scale circular practices in retrofits, a comprehensive systems approach with the necessary supporting infrastructure – take- back mechanisms, a steady supply of circular materials and a workforce skilled in circular retrofit techniques, at the city or regional level – is essential. Applying these practices to individual buildings or projects yields limited benefits. Emerging economies with relatively young building stock can incorporate circular practices into all new designs.Assessing the global uptake of circular retrofits Implementing circularity in retrofits demands a comprehensive systems approach and will vary by region.2 Circularity in the Built Environment: Unlocking Opportunities in Retrofits 15
