The performance of a building can be measured using a set of criteria, called Key Performance Indicators (KPI), linked to different features in a project. In the construction industry there are both subjective and objective KPIs, depending on what the main requirements are. The assessment of these KPIs are often related to building information modeling (BIM) which serves as a simulation method for mostly environmental and economical issues, meanwhile less options are available for evaluating qualitative indicators. This study aims to develop a process map in which a project manager can understand when different KPIs occur in a design process and how to make subjective KPIs measurable, thus usable for a BIM tool. Furthermore, an ideal process map is suggested to visualize appropriate BIM uses. The investigation of a case (Solar Decathlon Europe 2019) served as a test bed for identifications of subjective and objective KPIS. Documents analysis revealed a number of subjective KPIs which were further validated through semi-structured interviews with team members and leaders. Results showed that not all KPIs could fulfill the criteria of being comparable, collectable and measurable and it also proved that the evaluations of the different contest areas were subjective. Moreover, the results also indicates that the processes of the competing teams were lacking since not all necessary KPIs were taken into consideration. The overall process model graphically illustrates the process of design including when the KPIs occur and which Level Of Detail (LOD) is required. In conclusion, the contest itself is evaluated based on subjective opinions although most of the contest areas can be measured in a quantitative way.
