Measuring circularity from buildings to neighbourhoods

The circular economy (CE) aims to eliminate the concept of pollution and waste generation, maintain integrity product over several use cycles, focus on closing material energy loops. Circularity metrics are relevant for monitoring, reporting communicating CE implementation progress. Applied buildings, these deliver structured assessments through standardized indicators, which establish a common language among agents involved, help implement strategies assess potential technical options. Studies dealing with circularity buildings still scarce somewhat variable within an overall framework. Applications neighbourhoods even more incipient. This study applied selected two building cases different constructive characteristics, improve understanding how information is conveyed. highlighted challenges designs. However, such disregard environmental impacts required induce flows loop closure. It herein proposed that paired performance profiles produced by e.g., life cycle (LCA). "nested indicators" could be neighbourhood city scales referring LCA functional equivalency as "relevance" weighting criterion.
