ABSTRACT
ABSTRACT Under impulse of the Product Environmental Footprint (PEF) initiative, CEN/TC350 wants to extend the current set of LCIA impact categories in the EN 15804 (CEN 2013) for the LCA of construction products. This study investigates the practical implementation of those additional impact categories, their relevance on building level and how their inclusion influences the conclusions drawn from a building LCA. This is analysed based on a building case study. The results indicate that without any form of aggregation the additional indicators do not drastically change the conclusions drawn from a (comparative) building LCA; however they may influence the identification of the most impacting materials and processes. Moreover, the choice of the aggregation method may lead to different interpretations Finally, a variety of issues were identified concerning the robustness of the results, LCI data and/or characterisation factors related to the toxicity indicators, water resource depletion, and land use biodiversity.
