The essential role of design process visualization is to capture and represent design information as well as the change of design objects to keep track of reasons behind decision-making activities. The most prominent benefit of BIM, among its wide-spectrum potentials, would be that it made possible to consider simulated building performances such as energy efficiency for critical decision-making criteria even during the early stages of design project. Advanced design process visualization centered around BIM calls for reflecting performance-oriented design information generated from the various simulation tools from the early stages of building project. This will certainly demand a different approach in terms of process modeling and representation strategies. This paper introduces a visualization tool addressing these issues. It is on the top of an Open BIM Server to manage evolving IFC data model in a systematic way, integrating quantitative design data generated from performance evaluation tools. A data model was developed to represent the design process composed of evolving versions and alternatives interwoven with decision-making factors. The system, with its timeline-based interactive user interface, will give a better insight into the design process and easy access to the reasons behind decision-makings in an intuitive way.
