Digital technologies are changing the world of work. While virtual collaboration and digital planning have already become common practice, immersive technologies such as augmented reality are now extending the possibilities of how teams interact as well as planning and implementation of projects. The following article describes how immersive technologies can change the individual work experience and collaboration in interdisciplinary teams by extending reality. In this context innovative knowledge transfer is a decisive success factor. The demonstrator with the name Build Green makes these future working environments tangible—using the example of a large construction project in Potsdam, Germany, namely the Kreativ Quartier Potsdam, which is due to be completed in 2026. Build Green shows how digital and immersive technologies are used in the construction process—for more efficiency, more cooperation, more sustainability, and more transparency in knowledge transfer in complex projects. In this way, Build Green makes future dimensions of virtual teamwork experienceable. Planning data, 3D models, and information on sustainable building materials are integrated into planning practice in an extended reality environment. From each building to individual components, sustainability data can be specifically examined. This simplifies cooperation and the sharing of knowledge in real time between planning offices, architects, builders, and construction companies. The Build Green demonstrator illustrates the potential of immersive technologies and their added value for those involved. Furthermore, the conclusions and lessons learned from this project can be transferred to other sectors in production, services, and crafts, as well.
