Life Cycle Analysis Challenges through Building Rating Schemes within the European Framework

The decarbonisation of buildings is a crucial milestone if European cities mean to reach their mitigation targets. construction sector was responsible for 38% the GHG emissions in 2020. From these emissions, 11% calculated be currently embodied building materials. In this context, an evaluation from life cycle perspective becoming increasingly necessary achieve objectives set. Currently, there are different rating systems (BRS) at level that allow degree sustainability buildings. During study, authors have evaluated what extent and how most extended five BRS (NF Habitat HQE, VERDE, DGNB, BREEAM, HPI systems) framework integrated methodology during process. Four methodologies been used research order analyse systems: quantitative assessment, multi-level perspective, mapping–gap analysis, expert interviews. Although each has produced results, need harmonise criteria level, insufficient consistency data software, availability skilled LCA professionals wider market penetration, among others, should highlighted. quality harmonised products required give aggregated transformative results.
