JMK: Congratulations on winning the Straubing Culture Prize! Has the prize money of €3,000 already been spent?

PK: Thank you very much! The money hasn’t been spent yet, but it is planned. I would like to use it to produce a series of three works that I want to paint exclusively with lapis lazuli. I just want to experiment with this great material.

I have discovered for myself that I find shapes and shadows much more exciting than concrete, elaborate motifs. Haute couture and haute couture photo shoots are an important source of inspiration for me because I find the silhouettes particularly exciting. I also want to create large-format works.

JMK: So it’s a very sensible investment in future works and not in haute couture, for example?

PK: No, I always reinvest.

JMK: You’ve already mentioned it: you often use expensive materials such as lapis lazuli and make your own colors from the pigments. Why do you go to such lengths and not just buy ready-made tube colors?

PK: There are two reasons: Firstly, I want to honor the old masters, and secondly, I definitely used tube paint at the beginning of my studies, but was never satisfied with the result. I then went to Dr. Kathrin Kinseher, the head of the painting technique workshop at the Munich Academy, and told her that the colors didn’t have the brilliance I was looking for. The colors always looked a little “dirty”. She then explained to me that some of the pigments in the tube paints are not compatible with each other. A good example is titanium white, which often contains other substances. But I want the pure titanium white. So I make it myself to get the pure pigment. For me, added substances always change the color, which I notice and which bothers me.

JMK: You also make your canvases yourself, which means you stretch them onto a stretcher frame yourself. That’s also very time-consuming, you could also buy them.

PK: I’m a material fetishist. Prefabricated canvases don’t have the fabric quality I want. I use a special fabric from France that is particularly fine but still very thick. This is also very important to me with clothing, I really like firmer and thicker fabrics and this is where fashion and art come together again in my work. The feel of the canvases is simply important to me; they have to feel right to me.

JMK: You mentioned the haptic quality, which is something you’re familiar with from museums, that you shouldn’t touch works of art. Can the viewer see or recognize the special feel or the structure of the canvas?

PK: I always invite people to touch the work if they are interested in how I work. I also work a lot with copper or porcelain as a support material in my art and have developed a process that makes porcelain less brittle. I think it’s very important that people can touch it, because they are usually surprised at how it feels. I’m a very tactile person myself and I like to feel fabrics when I’m making clothes or buying fabric for canvases. I’m always very touchy.

JMK: I can totally understand that, you can also tell the fabric qualities: not all silk is the same and not all cotton is the same.

PK: Exactly, and I usually cover my work with a resin or varnish. So it’s not so bad if it gets touched on the side. At my exhibition in Straubing, for example, I have two works hanging that are made with organic material that will never dry. I poured a very thick layer of epoxy resin over it and it has a really cool feel. People always get really close to it and when I notice that people want to touch it, I go up to them and tell them that they are welcome to do so. That’s part of it for me. I want my art to appeal to different senses, which is why I often make music installations or play with scents. It is also important to me how the space in which my art is presented is designed. I always keep that in mind. Last January, for example, I wrapped an entire room in 3,000 disinfectant wipes with an artist friend, Sandro Prodanovic, which we glued, sewed and stapled together. It is simply important to me that you can immerse yourself in my art and that all your senses are engaged.

JMK: Of course, it’s also very exciting that you work together with other artists …

PK: I always enjoy doing collaborations. Perhaps I’ve picked that up a little from the fashion industry. It’s simply exciting when you get involved with another artist and then get into an exchange not only verbally, but also in the work process.

JMK: How should I imagine your working process? You just said that you cover the canvases yourself, you make the colors …

PK: I actually do everything myself, I hardly ever buy anything ready-made. I’m so obsessed with materials that I always want to know what something is made of. That’s also advice I give to first semester students: Get to grips with the material! If you know what you can do with which material, you work in a completely different way.

JMK: And what happens next? Do you prepare the materials and the canvas and then make preliminary studies? Or do you paint directly onto the canvas?

PK: It varies a lot. Sometimes it starts with a study, but I can like it so much that I leave it at that. But this study can still serve to make a painting. Although I pay very close attention to the ground, I rarely actually make preliminary sketches. I often paint freehand, because sketches often give me the feeling of being constricted. I also don’t make a grid on the canvas.

JMK: I recently read something about a painter whose painting was examined more closely with X-rays. It was discovered that he had made changes during the work process. Could something similar be found in your work?

PK: I also make a certain preliminary sketch, but I do it so that I can use it within the work to make the background look a bit dirtier. I usually do the sketching with graphite or charcoal, which I make myself. I burn willow wood for this. I then spread and dilute this black pigment with oil directly on the canvas. In combination with the bright colors that I then apply, I have a completely different effect.

JMK: Where do your ideas come from?

PK: I often come up with motifs when I go for a walk. Then I might see a relief or window that I really like. I then pick that up. But also stories that people tell me.

JMK: Are there also artists who influence you? I know from your work that the motif of a blue horse crops up frequently. We’re sitting here in Munich, so I quickly think of Franz Marc and his blue horses …

PK: Franz Marc has to do with the fact that I used to go to the museums in Munich quite often with my grandma and my mom, and the Lenbachhaus was often there. I had the “Blue Horse I” hanging as a poster above my bed. Of course, that left a lasting impression. Apart from that, I like Basquiat’s work, you can see that in my paintings too. I also have a few favorite artists, most of whom are no longer alive, but who generally have no influence on my work. Francis Bacon or Louise Bourgeois, for example. I’m not an installation artist, I’m currently doing pure flatware, i.e. painting. But I find cages and spaces very exciting, and I’m particularly interested in the dark and abstruse. I then incorporate the input I get there into my works and translate it into painting.

JMK: You can see that very clearly in your works. They are quite dark motifs, such as skulls.

PK: Vanitas motifs are definitely part of my work. But depressive moods also appear. I worked with borderline patients for a while, which resulted in very dark works. But that was too much of a burden for me in the long run, so I didn’t continue.

JMK: You also said that you take your lead from the old masters, at least in the material production process.

PK: I’m a bit conflicted about that now. I used to love visiting museums like the Louvre or the Alte Pinakothek here in Munich, but at the moment I can no longer see the works exhibited there in the same way. I’ve had my fill of them, so to speak. But their craftsmanship impresses me. They still did everything themselves because tube paints, for example, didn’t even exist yet. I find this dedication impressive. Many artists no longer go to that effort today. But once you start making the materials yourself, you don’t want to use anything else.

JMK: What are you working on at the moment, what are you working on?

PK: At the moment I’m preparing an exhibition in Paris, in the Marais. I’m very happy about that because I really like this area of Paris, it’s one of my favorite neighborhoods. The next work on paintings will be my homage to haute couture, which we talked about at the beginning. The designer Martin Margiela in particular serves as my inspiration. I find his deconstructed designs super exciting. The extravagant shapes he has created influence me. I am particularly interested in playing with shapes, as this allows viewers to develop their own stories about the work. This was also important to me in the Straubing exhibition, hence the title “Somewhere between them and us”. I am fascinated by the space between the artwork and the viewer that opens up, which is empty at first. As a viewer, you can then fill it with your emotions, your perceptions, your memories and perhaps even start dreaming. That’s how I feel about works by Chagall, they always catch me. A few of his things also resonate in my art.

JMK: What are your upcoming exhibitions? Where else can I see you apart from Straubing and Paris?

PK: There will probably be another exhibition in Milan, and in May we have another class exhibition here in Munich at the Academy of Fine Arts.

JMK: Final question: do you have an exhibition tip?

PK: Definitely the Kafka exhibition at the Villa Stuck. It won’t be on for much longer, but it’s very good. Then I would like to see the Mark Rothko exhibition in Paris at the Fondation Louis Vuitton. In the Tate London, the Expressionist exhibition with the loans from the Lenbachhaus and then in Munich in the Kunsthalle the exhibition about the designers Viktor & Rolf. There’s a lot more, I have a whole list.

Smart Envelope: facades as an energy machine

Building design
Modern high-rise façade as a smart envelope that turns the building envelope into an energy machine and climate-regulating interface.

Contemporary high-rise façade shows how the building envelope generates energy, regulates the climate and networks data in the smart building.

The façade has always been the stage of architecture – but now it is becoming a power station. Smart Envelopes promise nothing less than the revolution of the building envelope: energy generator, climate regulator, data interface. But how far have we really come? Is the façade as an energy machine just another buzzword from the kitchen of the future, or is there more to it than that? Welcome to the engine room of building culture – and to the debate about the façade of the future.

  • Smart envelopes are redefining the role of the building envelope: from passive layer to active energy system.
  • In Germany, Austria and Switzerland, pilot projects are becoming real innovation labs – but the big breakthrough is yet to come.
  • Digitalization and AI are catapulting façade planning into a new era of real-time control and predictive maintenance.
  • The sustainability debate is forcing planners, building owners and industry to adopt radical strategies: circular economy, CO₂ neutrality, resource efficiency.
  • Specialist knowledge of material technologies, system integration and building automation is becoming mandatory for everyone involved in construction.
  • The façade is becoming an area of discussion between digitalization euphoria, allergy to standards and ecological responsibility.
  • Global pioneers are setting the pace – but regional building culture remains stubborn and idiosyncratic.

From façade plaster to powerhouse: where do the DACH region and the global market stand?

The façade, the eternal stepchild of German building regulations, is preparing to become the rock star of the energy transition. What used to be regarded purely as weather protection cladding or at most as a design statement is now being overloaded with technologies and functions that sounded like science fiction just a few years ago. In Germany, Austria and Switzerland, we are seeing a cautious but steady approach to the topic of smart envelopes. While Switzerland is developing and testing innovative façade systems with renowned universities such as ETH Zurich, Austrian pioneers such as those in Vienna are focusing on large-scale pilot projects that combine photovoltaics, adaptive shading and green façades. In Germany, on the other hand, there is still a certain amount of skepticism – the fear of breaches of standards and investment risks is too great, and mistrust of new technologies is too deep-seated.

In an international comparison, the DACH countries are lagging behind the pioneers from Asia, Scandinavia and the Netherlands. In Singapore, for example, building-integrated photovoltaic modules and intelligent shading systems have long been standard in many new public buildings. The Dutch rely on circular façade components that can be recycled at the end of their life cycle. Germany, on the other hand, is still struggling with the question of how innovative façade solutions can be integrated into the jungle of paragraphs in the state building regulations and the thicket of DIN standards. But the signs are pointing to change: more and more competitions are awarding prizes for smart envelopes, and more and more investors are demanding green building certificates, which are almost impossible to obtain without active façades.

The central challenge remains the balancing act between design standards and technical complexity. This is because the façade as an energy machine is no longer a monolithic component, but a hybrid system that generates, stores, distributes and controls energy. This not only requires new skills from architects and engineers, but also a radical rethink in the cooperation between planning, execution and operation. The classic division between shell and technology is passé – anyone planning a façade today has to be an energy manager, material scientist and system architect all in one.

The DACH region at least shows that it is capable of learning. In Zurich, for example, entire city districts are being equipped with smart envelopes that feed solar power into the local grid and are controlled via digital platforms. In Vienna, façades are being fitted with sensors that adapt their shading to the position of the sun in real time. And in Munich, pilot projects are being ventured that even integrate wind energy into the façade envelope. However, all of this remains the exception rather than the rule for the time being – the comprehensive rollout of smart façade technologies is still a long way off.

Conclusion: the façade as an energy machine has long been more than just a PR stunt. It is the logical next step in a building culture that needs to reinvent itself. However, there is still a gap between aspiration and reality that can only be closed with courage, knowledge and a willingness to experiment. The next few years will show whether we are ready to really turn the façade into a power plant – or whether everything will remain the same in the end.

Digital intelligence in the building envelope: from the control box to the learning façade

Digitalization is the turbocharger for the smart envelope. What began with timers and light barriers is now an ecosystem controlled by AI and big data. Sensors measure temperature, humidity, light intensity and air quality on every square meter of façade. Intelligent algorithms optimize shading in real time, control the opening of ventilation elements and regulate the integration of photovoltaic modules. The façade thus becomes a cyber-organism that not only reacts to external influences, but also makes predictions and adapts to changing conditions.

The use of artificial intelligence in particular is opening up new horizons. Predictive maintenance – i.e. the predictive maintenance of façade components – is only possible by evaluating huge amounts of data. For example, PV module or drive failures can be detected and rectified at an early stage before they lead to energy losses. At the same time, the digital networking of façade elements enables unprecedented system integration: shading, ventilation, energy generation and building technology communicate in real time – not only in individual buildings, but increasingly also on a neighborhood scale.

The flip side of the coin: technical complexity is increasing exponentially. Planners, engineers and operators have to deal with new tools, protocols and interfaces. The classic façade detail is suddenly a digital twin that communicates with BIM systems, IoT platforms and cloud services. Anyone who misses the boat here will quickly become an extra in their own project. The requirements for data protection, IT security and system reliability are increasing – and with them the responsibility of those involved.

In practice, it is clear that the digitalization of the façade has not only technical but also cultural limits. Many building owners and users are skeptical about permanent data collection. The fear of loss of control, data misuse and technical overload is real – and not entirely unfounded. Transparency, comprehensible operating concepts and robust security architectures are required here. The successful smart envelope is not the one that can do everything, but the one that remains comprehensible and controllable for its users.

The international discourse has long seen the digital façade as part of a networked ecosystem of smart buildings, smart grids and urban energy management systems. Not much of this can be seen in the DACH region yet – but the course has been set. The next generation of façades will not only be built, but also programmed, monitored and continuously developed. The façade of the future is a learning, adaptive system – and the construction site fence no longer marks the end, but the beginning of its development.

Sustainability or greenwashing? The challenge and opportunity of the façade energy machine

The sustainability debate has fully embraced the façade as an energy machine. Anyone who still believes that a few PV modules on the roof can improve a building’s environmental footprint has not heard the last word. The CO₂ footprint of the building envelope has become a key criterion – from the extraction of raw materials to production and dismantling. Smart envelopes must be able to do more than generate energy: they must save resources, extend life cycles and be thought of in terms of circular material flows.

Integrating renewable energies into the façade is just the beginning. Materials such as recycled aluminum, bio-based composites and adaptive glass are on the rise. The first façades that can be completely dismantled and separated by type are being built in Vienna. In Zurich, research is being carried out into façade modules that can be easily dismantled and recycled at the end of their life cycle. But despite all the progress, the reality remains sobering: the majority of existing façades are energy inefficient, resource-intensive and technically outdated. The refurbishment backlog is enormous – and the implementation of modern smart envelopes often fails due to a lack of money, building regulations or user acceptance.

Another problem: greenwashing. Many manufacturers and planners adorn themselves with the label “smart” or “sustainable” without delivering real system solutions. A PV façade alone does not make an energy machine. Only the interaction of energy generation, storage, control and material cycle leads to a real sustainability gain. If you don’t do the math properly here, you quickly lose credibility – and end up damaging the whole concept.

The solution lies in the radical integration of sustainability at all levels. This means: life cycle analysis as early as the design phase, consistent use of recycled materials, modular construction methods for easy dismantling and linking with urban energy networks. Digital tools and AI can help to master complexity and objectify sustainable decisions. But they are no substitute for critical thinking and the responsibility of planners.

The façade as an energy machine is therefore both a touchstone and an opportunity. It forces the industry to finally take sustainability seriously – and at the same time provides the stage on which innovative solutions become visible and measurable. Those who only focus on cosmetics will lose the trust of investors, users and society. Those who boldly shape change can make the façade the key to the building turnaround.

Specialist expertise required: what professionals need to know about smart envelopes

Planning and implementing smart façades is not a hobby for technology nerds, but a highly complex task that requires interdisciplinary expertise. Architects, engineers, façade planners and technical building services experts have to engage with completely new interfaces. Materials science, thermodynamics, electrical engineering, automation, digitalization – all of this merges into a requirement profile that is hardly taught in traditional courses. If you want to stay in the business, you have to train, educate and, above all, network.

The technical know-how ranges from the selection of suitable photovoltaic or solar thermal modules to the integration of sensors and control technology to coupling with building management systems. The interfaces between the façade, building services and IT are critical – this is where it is decided whether the system ultimately works or remains in permanent fault mode. Errors in planning or execution not only have aesthetic, but also energy and economic consequences. The times when façades were designed according to the principle of “form follows function” are over – today, “form follows data” applies.

Legal and normative knowledge is also required. The multitude of building regulations, DIN and EN standards, fire protection regulations and funding programs is a minefield in which only those who are constantly up to date can navigate safely. At the same time, there is growing pressure to implement innovations despite regulatory hurdles and to avoid mistakes in the process. The legal gray area of new technologies requires tact and patience – but also the courage to question existing rules and develop them further.

One aspect that is often underestimated is user acceptance. The best smart façade is of little use if it is perceived as complicated, unreliable or disruptive. Usability, ease of maintenance and transparency of the systems must be considered from the outset. Professional communication, participatory planning processes and comprehensible user interfaces are not an optional extra, but a must. The façade as an energy machine is only successful if it blends organically into the building’s usage concept – and is not perceived as an extraneous technical object.

Last but not least: international networking is becoming increasingly important. Those who rely solely on regional solutions risk technological standstill. Looking outside the box – towards Asia, Scandinavia or the Netherlands – shows what is possible when innovation, a willingness to experiment and regulatory openness work together. The clever professional learns from the best – and knows that the façade as an energy machine is not an end in itself, but a contribution to the building culture of tomorrow.

Facade controversy: visions, fears and the global discourse

There are few building components that generate as much debate as façades. Some see it as the key to climate change, others as an over-engineered playground for engineers. In between, the debate rages about aesthetics, cost-effectiveness and building culture. In the DACH region, the debate is often conducted with typical German thoroughness but little courage. The fear of planning errors, cost increases and technical defects paralyzes many decision-makers. At the same time, there is growing pressure from investors, politicians and society to finally decarbonize the building sector. The façade is at the center of this conflict of objectives – and is becoming a symbol of change (or failure) in the sector.

There are plenty of visionary ideas: façades that generate energy from the sun, wind and rain. Envelopes that open, close or change color depending on the weather. Buildings that serve as local energy stores for entire neighborhoods. The technical possibilities are there – but implementation often fails in practice: too expensive, too complex, too little tested. The debate about the façade as an energy machine is therefore also a debate about willingness to take risks, innovation culture and the relationship between technology and building culture.

The criticism of smart façade solutions is justified: Many systems are not yet fully developed, require a lot of maintenance or are only economical under laboratory conditions. The danger of “technocratic bias” is real – if algorithms and IT experts take control, there is a risk of alienation from user needs and architectural quality. At the same time, there is a vision of establishing the façade as a democratic interface between people, technology and the environment through open interfaces, transparent data and participatory planning.

In the global discourse, smart envelopes have long been part of a larger narrative: the city as a power plant, the building as part of the urban energy system, the façade as an interface between inside and outside, man and machine, nature and technology. The DACH region faces the challenge of not only copying these developments, but also developing them further with its own building culture and design quality. The balancing act between high-tech and handshake, between algorithm and architectural language remains the great challenge.

One thing is certain: The façade as an energy machine is not a sure-fire success. It is a field of experimentation, a source of friction and a laboratory for the future. Anyone who wants to seriously engage in the discourse must be prepared to question old certainties, take risks – and understand the façade as a place of permanent negotiation between technology, aesthetics and society. It remains exciting. And that’s a good thing.

Conclusion: The façade of the future – not wallpaper, but a driver of the building revolution

The façade is dead, long live the façade. What used to be considered an architectural sideshow is now the innovation laboratory of architecture. Smart envelopes are the key to climate-neutral, digital and resilient cities. They challenge us to rethink, plan and build – and sometimes to fail. Those who take the plunge can raise the building culture of the DACH region to a new level. Those who wait and see risk being overrun by the global pace. The façade as an energy machine is not a trend, but a necessity. And for all its complexity, it is also an invitation to design, experiment and think ahead. The future of architecture will be played out on the envelope. And those who fail to recognize this will be left outside.
