The Facade Tectonics Institute’s biennial World Congress gathers the built environment’s most influential players for blind, peer reviewed paper presentations, expert-led group discussions, highly curated content, poster presentations, a dedicated virtual Expo (vExpo) and exclusive networking opportunities. This year’s World Congress will be presented online through a virtual platform providing a unique forum for a diverse cross section of the design and real estate communities to discuss the innovations and advancements revolutionizing the design and delivery of the building skin.

“The digital transformation will change everything” – with this quote in mind a deep look into the current façade business will be given with a special attention to digitalization.
This paper provides insights into the current situation from the perspective of an international façade system supplier and gives examples from daily work and scientific research projects.
Digitalization influences the façade business already in nearly each planning step. Renderings and visual simulation helps the architect to make decisions in the early planning stage. In addition, the development of 3D visualization has led to the creation of 3D tutorials for installations purposes. Finite element analysis, parametric planning tools and rapid prototyping are used in the façade system development to control design parameters without the necessity of a physical mockup. In the future, the cyber physical systems and 3D-tutorials in combination with synchronization of the data from the digital building twin will lead to zero tolerance fabrication and installation of complex façade products with sensor/motor- interfaces. These sensor driven, automated and interconnected products – like the so-called active noise cancelling façade components – are the base for an intelligent, self-controlled building envelope. Further innovations are expected in the process steps of façade maintenance and upgrading that will have huge consequences regarding a planned and controlled end of life.
The above shows that digitalization is already established in each step of the current façade life-cycle. An interconnection of these currently isolated digitized steps will lead to a digital transformation of the full process. The result would be a new digital life-cycle of the building envelope with a continuous data flow and indispensable consequences throughout the full process that provides a fertile ground for innovations in the digital age.

Urban noise pollution is a major environmental health problem. International organizations are making efforts to prevent health damage due to high levels of noise in cities, but the design of the built environment typically neglects the acoustic impact of architectural projects. Building façades, covering a substantial part of the vertical surfaces of the urban fabric, have a significant effect on the wellbeing of the population and on the environmental impact of buildings. Façade geometries and materials interact with the diversity of sounds in the city composing soundscapes that influence the health, comfort, and productivity of people inside and outside of buildings. This study gives an overview of the elements involved in the composition of the urban soundscape and revises the potential effects of sound-reflective and sound-absorptive façades. With the purpose of exemplifying the integration of acoustic data into façade design processes, a parametric design workflow is developed to experiment with acoustic simulations of a street environment, alternating between sound-reflective and sound-absorptive façades.
