Briefing for Circularity. Translating EU policies into operational guidelines for the building project

The current EU interest in Circular Economy offers novel opportunities to move towards more sustainable production and consumption practices. Literature confirms that building stakeholders are expressing a growing demand of common references and tools to support the integration of circular principles in building processes. The paper introduces a methodological approach meant as an information support tool to translate EU circularity policies into guidelines for building design and management. Indeed, the challenge is to translate circularity objectives and targets into specific requirements expressed from one stakeholder to another, up to the last operator involved in the supply chain. The requests along the different levels of the supply chain must be consistent with each other and with the initial circularity objectives expressed at the origin by the client. Hence, starting by outlining the complexity of the fragmented building supply-chain, the paper identifies the proper level of detail for expressing circularity requirements and, therefore, for communicating mutually consistent circularity objectives at the different levels of the supply chain. Supporting the integration of circularity requirements within Project Briefs (design phase) and Invitations to Tender (management phase), the proposed tool lays the foundations for the experimentation of circular building practices and for the systemic evaluation of compliance with EU circularity objectives.
