What are the challenges in assessing circular economy for the built environment? A literature review on integrating LCA, LCC and S-LCA in life cycle sustainability assessment, LCSA

For circular economy (CE) to succeed, focus must be given to the service life phase and the reuse/recycle phase of building projects.  This involves more stakeholders both in the early decision-making phases of projects as well as in the design phase and impacts the project value chain.  Life cycle sustainability assessment (LCSA) integrates complementary measurement tools and techniques to support the transition towards circularity.  Life cycle assessment (LCA) measures environmental and resource impacts, life cycle costing (LCC) reveals various lifetime costs, and social life cycle assessment (S-LCA) evaluates potential social impacts of a product in its whole life cycle.
