Abstract [sv]

Detta arbete är genomfört med målet att tydliggöra hur en byggnads miljöbelastning kan reduceras. I en fallstudie av ett flerbostadshus i Gävle jämförs miljöbelastningen med hänsyn till utsläpp av koldioxid, övergödning och försurning. En komprimerad LCA utförs från två olika fall där den bärande stommen genomgår en förändring av betongväggar till väggar av korslimmat trä. Huset som utgör objekt för arbetet är hämtat från en vetenskaplig artikel som är gjord med syftet att jämföra de bärande egenskaperna hos trä- och betongväggar. Den komprimerade LCA:n har gjorts med mjukvaran One Click LCA som är ett beräkningsverktyg med fullt stöd för de krav och certifieringar som berör arbete med LCA. Resultatet visar tydligt att bytet till träelement i stommen bidrar till ett reducerat utsläpp och vidare så finns det stora miljömässiga besparingar att göra vid större utnyttjande av trä i konstruktioner.

Abstract [en]

This work is conducted with the aim of making clear how a building's environmental impact can be reduced. In a case study of an apartment building in Gävle, the envi-ronmental impact is compared with regard to carbon dioxide emissions, eutrophica-tion and acidification. A compressed LCA is performed from two different cases where the load-bearing frame undergoes a change of concrete walls to walls of CLT panels. The house that is the subject of the work is taken from a scientific article made for the purpose of comparing the load-bearing properties of wooden and con-crete walls. The compressed LCA has been made with the One Click LCA software, which is a calculation tool with full support for the requirements and certification that concerns work with LCA. The results clearly show that the change to wooden elements in the frame contributes to a reduced emission and furthermore, there are large environmental savings to be achieved with greater utilization of wood in struc-tures.
