This report provides a general framework for circular buildings and proposes concrete strategies and indicators for possible inclusion in BREEAM New Construction and Refurbishment & Fit-Out (NC & RFO). The aim of the report is twofold: to provide stakeholders from government, business and academia with a basic framework to approach circularity in buildings, and to accelerate the transition to a circular built environment by suggesting strategies and indicators for integrations into leading global standards for sustainable buildings like BREEAM.
