The potential for enhancing the sustainability and resource efficiency of built environments is great as regards integrating circular economy principles into green building practices. This research paper contains a detailed review of literature on the integration of circular economy principles into eco-design and sets out guidelines for efficient use of circular practices. The paper reflects on the main principles of the Circular Economy, examines their relevance to the construction industry and makes a point of highlighting how these approaches have an environmental impact as well as societal benefits. In addition, this report provides strategies and best practices for overcoming obstacles to adoption. The framework set out in this paper is a practical guide for stakeholders in the construction sector to integrate the principles of the circular economy into their projects, ultimately promoting a more sustainable and resource efficient built environment.
