Circularity in the Built Environment 2024

Retrofit-specific financial mechanisms for circularity BOX 10 Circular retrofits can be financed through savings on energy costs, repairs and maintenance. For example, in the United Kingdom, a social housing company finances an Energiesprong retrofit44 by combining savings on tenants’ energy costs with repairs and maintenance savings.45 This approach could also be applied for circular retrofits. Certifications and assurance are important enablers for the transition to a circular value chain and are likely to become more widely used in the years ahead. For designers, manufacturers and renovators, adopting recognized certification schemes ensures the credibility and quality of circular projects. Certifications such as the Leadership in Energy and Environmental Design (LEED), Passive House, German Sustainable Building Council (DGNB) and Building Research Establishment Environmental Assessment Method (BREEAM) can be used as practical guides to meet high energy-efficiency and sustainability standards. Even though each certification scheme has its own criteria and focus areas, all aim to promote environmentally responsible building practices. Establishing strategic partnerships across the value chain is necessary for fostering a systems approach to circularity. Collaboration among stakeholders allows for pooling of resources, expertise and financing. As highlighted in a previous white paper,46 the built environment is characterized by a decentralized and fragmented landscape, necessitating extensive coordination to close resource loops. Many participants in this sector lack traditional linear supply-chain relationships, making integration, partnerships and standardized requirements for circular materials vital. By working together, stakeholders can overcome these challenges and promote sustainable practices throughout the industry.3.6 Certifications and assurance 3.7 Partnerships and collaboration Circularity in the Built Environment: Unlocking Opportunities in Retrofits 23
