In the last few decades, information technology has brought about lasting changes to design and production processes. At the same time, our demands on design and building processes have increased in line with technical possibilities. Aside from unprecedented geometrical freedom, there is huge potential to optimize functions, energy and performance of constructions, buildings and services. Buzz words like Big Data, Industry 4.0 and The Internet of Things already point towards the next Digital Revolution. So what does this mean for building envelopes and their planning and building processes? How can an ever increasing network of information contribute to an optimization of today’s designs and constructions? These issues were addressed at the conference facade2015 which followed the same sequence, as the main phases of building development: planning, construction and operation. The potential, chances and risks of progressive digitalization with respect to the the building envelope were at the center of conference discussions.
