Critical analysis of environmental benchmarks for buildings

[摘要] To reduce the environmental impact of the building sector, environmental targets should be defined considering the full life cycle of buildings. In recent years various benchmarks based on Life Cycle Assessment (LCA) have been developed as part of regulations, labelling systems and sustainability rating tools. This paper presents the results of a critical analysis of six existing benchmarking systems. An overview is given of the different benchmark approaches, scope, applications and communication. The strengths and weaknesses of the various systems are highlighted. Based on the analysis, recommendations are formulated for the development of future LCA benchmarks for the building sector.
