Incorporating LCA and LCC into the decision-making process provides environmental and economic improvement for buildings. BIM offers a variety of strategies for integrating LCA and LCC studies into the building design. The following topics are essential to this integration process: visualizing the analysis results for different design options and reflecting the design decisions into the BIM model. The first part of this thesis deals with identifying different methods for visualizing the analysis results. In this regard, two chart groups were defined: criterion-specific and overview charts. In contrast to a criterion-specific chart, an overview chart combines various criteria into a single chart. The next step was identifying suitable chart types for each chart group. Furthermore, the second part of this thesis focuses on open BIM and its extension options to communicate design decisions to the BIM model. The BIM Collaboration Format was extended using BIM Snippets. Accordingly, a semi-automated method for updating the BIM model according to design decisions has been introduced. The presented visualization methods enable stakeholders to compare different design options according to their economic and environmental impacts. The developed semi-automated method reduces the effort required to update the BIM model regarding design decisions.     «
