Bad – The STEIN in March 2024

Building design

In this issue of *Badausgabe*, we presented two extraordinary projects that impress not only with their craftsmanship. A master bathroom made of Grigio Imperiale marble features clean lines, and the stonemason had to work with extreme precision in collaboration with the other trades. Precision also played a key role in the second project—a bathroom made of Brazilian quartzite—since the structural transitions in the STEIN’s grain had to be executed with millimeter-level accuracy during cutting. Flawless planning was essential here, as the slabs were non-interchangeable due to their unique structure.

Are you also frustrated by the many regulations and documentation requirements you have to comply with as a business owner? Excessive bureaucracy in our country has become a topic of discussion in many circles. The Federal Association of German Stonemasons (BIV) also has a clear stance on the issue. As a member of the German Confederation of Skilled Crafts (ZDH), it supports ZDH President Jörg Dittrich, who is calling on policymakers to finally stop trying to regulate everything down to the smallest detail. Above all, those affected must be consulted before new regulations are enacted. Starting on page 22, we take an in-depth look at this controversial topic.

At the same time, we’d like to invite you to join us in taking a first look at the latest projects from the stonemasons’ workshops. In our bathroom feature, for example, we present a master bathroom made of Grigio Imperiale marble, which impresses not only with its clean lines but also with the perfect interplay of the various trades involved. Read more about it starting on page 6.

The highest level of craftsmanship was also required for another bathroom made of fine natural stone. For the bathroom in their attic apartment, the homeowners wanted a real “eye-catcher.” This was achieved with “Explosion Blue,” a natural stone from Brazil that is still relatively unknown here. Find out how it was artfully crafted in the workshops of Huber Naturstein starting on page 12.

To find out which machines and tools are best suited for perfect miter cuts in bathroom construction, see page 30 and onward. Our author, Michael Spohr, visited three companies in his usual style and was shown many exciting, practical solutions by the people in charge.

Finally, we turn our attention to the other side of the world, Down Under: Quartz composite has recently been banned in Australia. Read on page 55 to find out what this means for the German market.

The La Serena residential complex is located in the west of Regensburg and comprises 18 identical-looking four- to six-storey buildings. There is space for a total of 460 apartments of various sizes. The density of living space is not noticeable, however, as wide footpaths, lawns and an artificial lake break up the ensemble. The color play of the surroundings is reflected in the façade cladding of the top floor, the balcony parapets and in the door and window profiles: the shade of green with a grey component according to the Sikkens color scale provides variety and enlivens the white façade.

Bauteam Tretzel, a leading property developer in the Regensburg area, was responsible for the design and construction of the housing estate. Managing Director Volker Tretzel and his team chose foil-laminated PVC profiles for the construction elements. Decisive factors for the decision: a good price-performance ratio, durability and freedom of design. The window construction company Jechnerer from Herrieden ordered the profiles from the system provider Profine with the “Renolit Exofol Fx” laminating film. The base film is made of colored acrylate, and another film protects against UV radiation. An additional layer of fluoroplastic ensures that the film can withstand extreme climatic conditions and provides protection against chemicals. Due to its low surface tension, it is dirt-repellent and scratches and scuffs cannot harm the textured surface. In the event that a window is damaged during delivery or installation, the Renolit film service or trained companies offer immediate repairs.

Cybernetics 2.0 sounds like the wet dream of technology-loving system architects, but it has long been the foundation of a discipline that needs to reinvent itself. Systemic architecture in the digital age is no longer an academic playground – it is the operating system for an industry teetering between climate crisis, lack of resources and digital overload. Anyone who still values form over function has simply not understood the signs of the times.

  • Systemic architecture is becoming the new leitmotif in Germany, Austria and Switzerland – digitalization and AI as drivers, but also as stumbling blocks.
  • Architecture is changing from an object to a platform: networked, adaptive and adaptive systems are replacing static design logic.
  • Cybernetics 2.0 means that buildings, neighborhoods and cities are becoming self-regulating ecosystems. Sensors, data, automation and interoperability are mandatory.
  • Sustainability is finally becoming technical: the focus is on circular economy, real-time monitoring and digital material passports.
  • Professionals need to radically expand their technical repertoire: data literacy, software understanding and algorithmic thinking are no longer an optional extra, but a survival strategy.
  • Systemic approaches are challenging the profession – and raising questions about authorship, control and ethics.
  • Central debates: Who owns the architecture in the system network? How can technological complexity be managed democratically?
  • In the global discourse, DACH countries are solid, but rarely visionary – role models can often be found in Asia and Scandinavia.
  • Conclusion: Anyone who ignores Cybernetics 2.0 is planning past reality.

Systemic architecture: from individual buildings to urban networks

The era of singular masterpieces is over. Systemic architecture no longer thinks of buildings, districts and cities as separate objects, but as nodes in a constantly changing network of data, functions and user interests. This sounds like philosophy, but it is bitter practice. The requirements for energy efficiency, user comfort and resource conservation can no longer be met with traditional design tools. In Germany, Austria and Switzerland, awareness is therefore slowly growing: without holistic, networked systems, even the most ambitious architecture will remain a mere exercise in form.

Cybernetics 2.0 is far more than just a buzzword. It is an attempt to understand the built environment as an open, feedback control loop. Sensors measure, algorithms control, users act, buildings react. What used to be marketed as an “intelligent house” is mutating into a self-learning neighborhood or even a data-based city. This may frighten some planners, but there is no alternative. After all, only those who think in systems can master the complexity of climate adaptation, the mobility transition and social integration.

Of course there is resistance. German building culture loves the solitary design, the clearly defined authorship. But anyone who still believes that they can control the energy flows of an urban district with a pen, paper and a bit of BIM is mistaken. In Switzerland, the first projects are emerging that see buildings as part of a regional energy system and communicate with neighboring structures in real time. Austria is experimenting with open data platforms that interconnect architecture, infrastructure and mobility. The trend is clear: systems thinking is replacing ego design.

In practice, this means that planning is becoming a control task. Architects not only have to design spaces, but also orchestrate processes. They become the conductors of a permanently fluctuating ensemble of data, technology and use. This is uncomfortable because it gives up power. But it is also an opportunity, because architecture can finally be geared to real needs and developments – and no longer just to the investor’s taste.

Anyone who refuses to embrace this paradigm shift will be left behind. Because digitalization knows no pardon. It is forcing all players to leave their comfort zones and think of architecture as a dynamic, networked system. That sounds exhausting, but it is simply the new reality.

Digitalization and AI: the invisible architects of the future

The buzzwords digitalization and artificial intelligence have long since entered the mainstream. But while many industries are already being driven by algorithms, the construction industry has traditionally been sluggish. In systemic architecture, however, digital technologies are no longer a gimmick, but a basic requirement. Sensor technology, data platforms, simulations and AI-supported decision-making models are the new tools – and they are changing everything.

In Germany, Austria and Switzerland, there are the first lighthouse projects that show where the journey is heading. Digital building twins, such as those being developed in Vienna and Zurich, link models in real time with the environment, user behavior and operation. Artificial intelligence predicts energy consumption, detects anomalies in the material cycle or suggests adaptive usage variants. This not only makes the architecture more efficient, but above all more flexible and resilient.

The real game changer, however, is the ability to self-optimize. Buildings that use AI to independently adjust their heating, ventilation and shading – this is no longer a dream of the future. Neighborhoods that control their energy flows according to weather, demand and grid load – already a reality. The challenge: all of this only works if data is open, interfaces are standardized and systems are interoperable. And this is precisely what is still lacking in Germany.

Many German cities and planning offices remain in pilot project mode. There is a lack of courage, know-how and sometimes simply a lack of political will to roll out the existing technologies across the board. Austria and Switzerland often take a more pragmatic approach, but are not digital pioneers either. A look at Asia or Scandinavia shows how much potential is wasted when people become entrenched behind data protection or federal responsibilities.

If you want to survive in the digital age as an architect, planner or engineer, you need to acquire basic technical knowledge. Data literacy, algorithmic thinking, an understanding of software architectures and interface management – this is not esoteric, but a professional reality. The new generation is growing up with it. Anyone who misses the boat will be degraded to being a vicarious agent of software manufacturers and energy suppliers.

Rethinking sustainability: from a green façade to a circular system

For a long time, sustainability in architecture was a question of material selection or insulation standards. Cybernetics 2.0 turns the tables: sustainability is now a systemic achievement. It is no longer a question of designing individual components to be energy-efficient. It is about optimizing, monitoring and continuously developing the entire life cycle of a building or district.

Germany, Austria and Switzerland like to present themselves as pioneers in sustainable construction. In reality, however, implementation often suffers from a lack of integration. The circular economy remains lip service as long as material passports and dismantling processes are not mapped digitally. CO₂-neutral districts usually only exist in renderings because energy flows are still controlled blindly during operation.

This is precisely where systemic architecture comes in. Digital twins, sensor technology and AI make it possible to measure resource consumption in real time, detect deviations and take immediate countermeasures. Intelligent façades react to environmental stimuli, adaptive energy systems adjust dynamically to consumption and availability. In Vienna, for example, the first districts are being used as test areas for circular construction. In Zurich, deconstruction processes are being digitally simulated in order to separate materials by type and reuse them. This is the future – and it is starting now.

Of course, there is resistance here too. The construction industry loves its routines, the trade its experience. But anyone who still believes that sustainability can be achieved without digital control and systemic networking is misjudging the scale of the task. The climate crisis will not wait until everyone involved has updated their Excel spreadsheets.

The solution is inconvenient but unavoidable: sustainability must become a data-driven discipline. Architects must learn to work with monitoring data, simulate scenarios and constantly scrutinize their designs. Only then will systemic architecture become a lever for a genuine building revolution.

A changing job profile: from construction artist to systems architect

The consequences of Cybernetics 2.0 for the profession can hardly be overestimated. While the traditional architect still shuttles between construction site visits and design meetings, systemic architecture demands a completely new understanding of their role. Architects become moderators of complex processes, mediators between technology, user interests and regulation. This sounds like a loss of control, but is actually an opportunity for professionalization.

Everyday life is changing radically: instead of making individual decisions, planners now coordinate entire system landscapes. They have to design interfaces, understand data flows and answer ethical questions about automation. This requires not only technical know-how, but also communication skills and a strong sense of responsibility.

Training is lagging behind this development. In many universities, BIM is celebrated as an innovation, while international pioneers have long been discussing semantic data models, self-learning systems and open platforms. If you want to keep up with global competition, you have to rethink. Further training, interdisciplinary teams and dialog with software developers are no longer an option, but a survival strategy.

Of course, there are also debates. Who controls the systems? Who bears responsibility when AI models make mistakes? How can complexity be managed without losing democratic control? The answers to these questions are still unclear – but they will shape the profession in the coming years.

One thing is certain: Anyone involved in systemic architecture must open up. To new technologies, new forms of collaboration and new ethical issues. Anyone who sees this as a threat will become an extra in their own professional field. Those who see it as an opportunity are actively shaping the future.

Discourses, dilemmas and visions: Cybernetics 2.0 in the global mirror

Systemic architecture is not a DACH phenomenon. Cities, planners and developers around the world are experimenting with cybernetic models, self-learning districts and digital governance systems. Singapore, Copenhagen, Helsinki and Shenzhen have long been further ahead than many German municipalities. They show what is possible when data, technology and urban development are considered systemically.

But there are also fault lines in the global discourse. The commercialization of system platforms, proprietary software solutions and the risk of algorithmic bias are causing fierce debates. Who controls the data? Who owns the decision-making power? How can technological complexity be managed democratically? Europe is looking for answers – and is often too busy with data protection to take over technological control.

There are plenty of visionary ideas. Circular cities that optimize their resource consumption in real time. Adaptive neighborhoods that respond to social and climatic changes. Architecture as an open, participatory platform that not only involves users, but also allows them to play an active role in shaping it. All of this is technically possible – if you want it to be.

But getting there is a rocky road. The biggest hurdles are not technical, but cultural. Distrust of data, fear of losing control and a longing for the “good old days” are blocking innovation. Yet courage is needed right now. Because the challenges are too great to be solved with the tools of the 20th century.

Cybernetics 2.0 is ultimately an invitation to understand architecture as a living, learning system. It forces everyone involved to think outside the box and take responsibility. Those who ignore this will be overtaken by reality. Those who help shape it will benefit from the opportunities offered by a networked, sustainable and democratic building culture.

Conclusion: Those who do not think systemically today will build the problems of tomorrow

Cybernetics 2.0 is no longer a utopia, but the basic prerequisite for sustainable architecture. Those who refuse to embrace it will, at best, remain the decorators of a dying industry. Those who embrace it open up new scope, more influence – and above all the opportunity to actively shape the challenges of the 21st century. Systemic architecture is uncomfortable, complex and not always glamorous. But it is the only way to make the built environment resilient, sustainable and liveable. Welcome to the age of thinking in networks.
