The comparison between different materials are quiet popular amongst construction products suppliers to promote the own product, if it succeeds in performance assessment against concurrent materials. Beyond this pure marketing related material comparison, in planning processes decision makers search trustful, transparent and independent assets of the ecologic impact of construction components. As surplus, they also request a bunch of facts to know about the components performance, from structural load-bearing to heat and sound protection. The dataholz.eu web-platform supplies a multitude of such data for timber components either timber-framed as well as for mass timber. Based on a coherent calculation method according to EN standards LCA-results for components are calculated, followed by an in-depth comparative analysis between variations of the same component composition. Overall results from traditional, frequent used indicators like GlobalWarming Potential are presented and discussed in the light of various compositions of the floor-slab components. As components are the basis for entire building-LCA we use our results from component level and try to relate it to full building LCA. In practice full building LCA are made ex post what makes them useless for decision making because building owners need information earlier on a reliable basis and not only on expert guess.     «
