Visions and developments for buildings in the digital age

The expansion of broadband networks, new radio technologies and ever more powerful end devices are the innovation drivers behind new digital applications. A further development is taking place in the building sector which will convert the building development process into a comprehensive, seamless digital and collaborative workflow. BIM describes this method, creating a digital prototype of a building — a twin — as an ideal result. This digital twin incorporates all the different technical disciplines in a digital planning result, forming a visual basis for ongoing decision and assessment processes. However, the digital building model does not only play a major role during the construction process. Particularly in the subsequent usage phase, it serves as a basis for operator processes concerning planning, execution and continuous improvement. Several examples, from both the construction and usage phase, illustrate current developments and applications. The building of tomorrow will respond to changing usage requirements, as well as to digitisation possibilities, and adapt accordingly. Four general theories, as well as examples of pilot projects and an outlook, underline and demonstrate this development roadmap.
