Developing whole-life carbon benchmark values for Norwegian buildings
Marianne Kjendseth Wiik
Abstract
Recent years have seen an increased focus on reducing embodied greenhouse gas (GHG) emissions from buildings. This is exemplified by the race to develop national roadmaps and GHG limit values for buildings. In this study, 186 existing Norwegian LCA building case studies are collected, analyzed, and presented to ascertain WLC benchmark values for Norwegian buildings. The results are shown for different building typologies, per life cycle module, and per building part. The results also show the development of GHG emissions from Norwegian buildings over time and give a projection of GHG emission limit values towards 2030 and 2050. The results can be used by policy makers in the development of national roadmaps and WLC limit values for buildings.
