Abstract [en]

The Swedish Government has set a goal to reach net zero emissions of greenhouse gases by 2045, which together with the commissioning to the Swedish Housing Agency to prepare requirements for a climate declaration that shall reduce the climate impact from buildings, has enforce the AEC industry to provide solutions that help reach these targets. The introduction of the integration of BIM technologies, together with the LCA methodology has been suggested as a key solution to solve this problem. To achieve the results for this study, two main objectives were stablished. The first objective was to develop a BIM model in SMC able to produce automated climate calculations. The second objective was to perform interviews with relevant actors about this tool. The integration of those objectives helped to answer the research questions of this study. This study provides a way of performing automated climate calculations for construction projects using classification of materials in SMC and calculations in Excel. It also has the ability to perform data visualization of the carbon footprints of the complements in the 3D models of the project using the GWP of the chosen materials. It can be said that it is a great tool to introduce to decision-makers an easy way to identify the hotspots of carbon emissions and choose more sustainable alternatives.

Abstract [sv]

Den Svenska Regeringen har fastställt ett mål att nå utsläppen av växthusgaser netto noll till 2045, som tillsammans med uppdraget till Boverket att förbereda krav på en klimatdeklaration som ska minska klimatpåverkan från byggnader har tvingat AEC-industrin att tillhandahålla lösningar som hjälper till att nå dessa mål. Införandet av integrationen av BIM-teknologier tillsammans med LCA-metoden har föreslagits som en nyckellösning för att lösa detta problem. För att uppnå resultaten för denna studie fastställdes två huvudmål. Det första målet var att utveckla en BIM-modell i SMC som kunde producera automatiserade klimatberäkningar. Det andra målet var att genomföra intervjuer med relevanta aktörer om detta verktyg. Integrationen av dessa mål hjälpte till att besvara forskningsfrågorna i denna studie. Denna studie ger ett sätt att utföra automatiserade klimatberäkningar för byggprojekt med klassificering av material i SMC och beräkningar i Excel. Det har också förmågan att utföra datavisualisering av kolavtryck av komplementen i projektets 3D-modeller med GWP för de valda materialen. Det kan sägas att det är ett bra verktyg att introducera för beslutsfattare ett enkelt sätt att identifiera de hotspots som koldioxidutsläpp och välja mer hållbara alternativ.
