Input–output and process LCAs in the building sector: are the results compatible with each other?

摘要: ABSTRACTBuildings are a major contributor to climate change. Use phase has traditionally been the focus area, but importance of construction-phase increased with emergence energy-efficient buildings. Life-cycle assessment (LCA) is arguably best method assess and analyze emissions caused by However, within LCA there two very different approaches – process input–output (IO) which lead results. When looking at scale published results, it evident that IO LCAs placed top end, bottom end. It thus questionable whether can provide data be used for decision-making policy formation. This study takes step toward filling this gap presenting comparison results pre-use residential concrete element building in Finland. Exactly same scope utilized order maximize comparability. The depict how main methods pro...
