Automated climate calculations and 3D value-based visualizations : An Integration of BIM and LCA
Sammanfattning: 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.
