About Introduction Principles of a Circular Economy Building and Construction Materials Design and Retrofit Regenerate Nature 4.1 Circular Building Design and Construction Strategies Designers of buildings and infrastructure are well-placed to challenge business- < as-usual approaches and unleash forward- looking designs that consider the entire lifecycle of an asset. Circular design and construction offers extensive environmental opportunities and socio-economic benefits if the appropriate design and construction strategies are implemented. In practical terms, it requires all stakeholders including investors, clients, developers and design teams to take a longer-term view, considering the past, present and future use of a building’s products and components – including how to procure, maintain and retain their value and usefulness over multiple lifetimes. Linking Net Zero and Circularity: The implementation of circular design principles is an essential part of the solution for a net zero carbon future. While industry has traditionally focused on addressing operational carbon, increased efforts to tackle embodied carbon emissions at a global scale must now be equally prioritised. WorldGBC’s Whole Life Carbon Vision calls for all new buildings to be net zero carbon in operation and all new buildings, infrastructure and renovations to have at least 40% less embodied carbon with significant upfront carbon reduction by 2030. By 2050, all new buildings, infrastructure and renovations must have net zero embodied carbon. 46 The Circular Built Environment Playbook
