Measuring emotions, designing buildings: What sounds like esoteric hocus-pocus has long been a harsh reality in the age of smart architecture. Emotion tracking is taking the design world by storm—and turning the architect’s role on its head. Are we ready for buildings that reflect and manipulate our moods?

For the first time, emotion tracking makes subjective user experiences measurable and planable.
New sensor technology, AI-powered analytics, and big data are creating an emotional data foundation for architectural decisions.
Germany, Austria, and Switzerland are experimenting cautiously, while international pioneers have long since begun building prototypes.
Emotion tracking promises greater user-centered design, but it also carries ethical and data protection risks.
Digital tools and AI are transforming the traditional understanding of design—and demanding new skills from planners.
The integration of emotional data opens up innovative approaches for more sustainable buildings and cities.
Architecture is becoming the interface between biometrics, psychology, and digital technology—with far-reaching consequences for the industry.
The debate centers on control, transparency, and the future of design autonomy.

Emotion Tracking: Between Smartwatches and Smart Buildings

Emotions have long been considered secondary in architecture. Some wanted primarily functional buildings, while others spoke of atmosphere without ever being able to explain how it actually arises. That is currently changing radically. Emotion tracking—that is, the collection and analysis of human emotional responses—is making its way into the world of design. This is made possible by biometric sensors, facial recognition software, eye tracking, and AI-powered data analysis. What was previously used in marketing or user experience research is now becoming the basis for design decisions in construction. The construction site of the future knows how its users feel—and adapts accordingly.

This technology is anything but a pipe dream. Prototypes are already being tested today in laboratories and on test construction sites: sensors on doors that measure heart rate and skin conductance; camera systems that analyze facial expressions; and wearables that measure stress levels in real time. The architecture industry faces the challenge of not only collecting this flood of data but also interpreting it meaningfully. What does it mean if a space is proven to cause discomfort? Does the design need to be changed? Or is the user the problem?

This is precisely where the debate begins, because emotion tracking is changing how designers view their own role. Subjective impressions are suddenly translated into numbers and graphs. Gut feelings, once the domain of intuition, are becoming a benchmark. Anyone designing buildings today must ask themselves how far this new transparency should go—and whether it truly leads to better spaces, or merely to a new kind of conformism.

So far, the pioneers have been primarily based outside Germany. In the U.S., Japan, and Scandinavia, the first projects are emerging in which users’ emotional reactions are continuously recorded and fed into building automation systems. In Germany, Austria, and Switzerland, people are more cautious. There are research projects and individual initiatives, but widespread adoption has yet to materialize. The concerns are too great: Who controls the data? Who guarantees that it won’t be misused?

Nevertheless, one thing is clear: emotion tracking is coming. The question is not if, but when and how. Planners who do not address this topic now run the risk of being left behind by international developments. Buildings that are not only energy-efficient but also emotionally intelligent are becoming the new gold standard—and are fundamentally transforming the industry.

Technology, Trends, and Pitfalls: How Emotion Tracking Is Changing Architecture

The term “emotion tracking” encompasses a broad spectrum of technologies. From simple mood surveys via apps to complex real-time analyses using EEG or skin sensors, anything is possible. The architecture industry is increasingly turning to methods that originally stem from human research or neuromarketing. Technological development is rapid: Artificial intelligence can now recognize patterns in the data that even experienced psychologists would overlook. This results in data-driven user profiles that provide insights into well-being, stress, and satisfaction within a space.

These new possibilities have an enormous impact on the design process. Whereas architects used to rely on their own sense of space or on subjective user feedback, they now have access to objectified emotional data. This sounds like progress, but it also carries risks. After all, measuring emotions is anything but trivial. How do you interpret an elevated heart rate? Is it excitement, anxiety, or joy? The risk of misinterpretation is high, and the temptation to rely on seemingly objective numbers is even greater.

Another trend is the integration of emotion tracking into building automation. Smart systems no longer control lighting, acoustics, or temperature solely based on schedules or predefined scenarios, but react dynamically to users’ emotional states. An office that recognizes when concentration is waning and automatically creates a more relaxed atmosphere—such scenarios have long been part of pilot projects. But the technology has its pitfalls. Who decides which emotions are “correct”? And how do you deal with unwanted reactions?

Advancing digitalization also brings new challenges for data protection. Emotions are highly personal information. Their collection, storage, and use raise ethical questions that have yet to be adequately addressed. The architecture industry must grapple with new legal frameworks and develop standards that ensure user protection. Without clear rules, there is a risk that emotion tracking will degenerate into a surveillance measure—and permanently damage trust in digitalization.

From a technical standpoint, emotion tracking requires new skills within the design team. Architects must learn to handle data, analyze it, and critically evaluate it. A basic understanding of psychology will become just as important as an understanding of algorithms and AI. The industry is facing a paradigm shift: architecture is not only built, but also measured, optimized, and constantly reevaluated—with all the opportunities and risks that entails.

Emotion Tracking in the DACH Region: Between a Thirst for Innovation and Fears About Data Privacy

In Germany, Austria, and Switzerland, the topic of emotion tracking is marked by the usual tension between a desire for innovation and skepticism. On the one hand, there is a growing number of research projects, pilot studies, and startups driving the field forward. Universities are collaborating with technology partners to make emotional data usable for architecture. Initial pilot projects, for example in office buildings or the healthcare sector, show that user satisfaction can be measurably improved when emotional data is incorporated into the planning process.

On the other hand, there is considerable reluctance. Above all, data protection and ethical concerns stand in the way of widespread adoption. The legal framework in the DACH region is strict, and many potential building owners shy away from using technologies that could be perceived as invasive or intrusive. The fear of losing control and of manipulation is ever-present. Who wants their stress levels to serve as the basis for building adjustments—or even for disciplinary measures at work?

Nevertheless, innovative approaches are emerging throughout the German-speaking world. In Switzerland, for example, sensor data in residential buildings is analyzed anonymously to draw conclusions about residents’ well-being and continuously optimize interior design. In Austria, experiments are underway with emotional feedback systems in schools to dynamically adapt learning environments. And even in major German cities, initial concepts for “emotional smart offices” are emerging, designed to boost both productivity and satisfaction.

The technical infrastructure is in place, and expertise is growing—but cultural change is progressing only slowly. Many planners and building owners still view emotion tracking as a gimmick or a passing fad that will soon disappear. That is a mistake. The global trend is clear: emotional data is becoming an integral part of digital construction. Those who turn a blind eye to this risk falling behind in the international discourse.

What is missing are binding guidelines and best-practice examples that demonstrate how emotion tracking can be integrated into practice in a meaningful, ethical, and legally compliant manner. The industry is called upon to set standards, define quality criteria, and actively involve users. Only in this way can trust be built—and the technology’s potential be fully realized.

Sustainability, Debates, and Visions: Is Emotion Tracking a Game-Changer?

The integration of emotional data opens up new avenues for sustainable architecture. Understanding how spaces affect well-being allows us to design buildings that are not only more energy-efficient but also healthier and more user-friendly. Emotion tracking reveals where stress hotspots form or where the quality of the environment suffers. This allows for targeted measures to improve the indoor environment—and thereby also reduce resource consumption. Sustainability takes on a new dimension: it is no longer just a matter of materials or energy, but also of emotional value.

But the approach is controversial. Critics warn against a “technocratization” of architecture in which human emotions become a commodity. Are users becoming guinea pigs in a permanent emotional laboratory? Is a new form of surveillance emerging, in which the building knows more about its occupants than they do themselves? The debate is in full swing. Experts are engaged in heated discussions about how much control and transparency are necessary—and where the line between that and manipulation lies.

Visionary voices, on the other hand, see enormous potential. Emotion tracking could become the foundation of a truly user-centered architecture that takes individual needs seriously and turns buildings into living organisms. Instead of static spaces, adaptive environments are created that constantly adjust to their users. The boundaries between architecture, psychology, and technology are blurring. Buildings are becoming active participants in what’s happening—with all the opportunities and risks that entails.

Another aspect is the role of artificial intelligence. AI systems can recognize emotional patterns, make predictions, and provide recommendations for interior design. They could become sparring partners for architects—or competitors. The question of how much autonomy should be granted to the algorithm remains unresolved. Only one thing is certain: Those who wisely combine AI and emotion tracking can revolutionize the design process—or turn it into a black box in which humans become mere extras.

Ultimately, the topic also has a global dimension. Emotion tracking is part of a worldwide discourse on the digitization of construction. International examples show how far this journey can go—but also what obstacles lie along the way. The architecture industry in the DACH region must decide: Does it want to help shape the future or just watch from the sidelines?

Conclusion: Between Euphoria and Skepticism—Emotion Tracking as a Litmus Test for the Industry

Emotion tracking is more than just a new technological trend. It is a paradigm shift that challenges architects’ self-image and the fundamentals of building design. The opportunities are enormous: user-centered design, sustainability, and innovation are being taken to a new level. But the risks are just as great. Data privacy, ethics, and creative freedom are coming under pressure. The industry must learn to handle emotional data with confidence—and to use it wisely without falling into the trap of technocracy. Those who shy away from the debate will lose their relevance. Those who experiment boldly can actively shape the future of architecture. One thing is certain: emotions cannot be dismissed through argument alone. It’s time to finally take them seriously—and make them part of the architect’s toolkit.

Sculpture of the month: Stone postcard from Solingen

Building design

Bush knife: The Solingen cutting tool turned stone on the right by the hedge. On the left, an unnamed steel sculpture by Thomas Röthel

Steel products from Solingen, especially knives, are known all over the world. Even in the South American jungle, Bud Spencer warned his partner Terence Hill of a “postcard from Solingen” in his back – i.e. the switchblade in the hand of the sneaking attacker – in the 1973 cinema classic “Two Heavenly Dogs on the Road to Hell”. For the tenth anniversary […]

The Solingen trade fair focuses on the products of local industry, in the classic city of blades, of course, especially the well-known steel products. Directly opposite the venue of this largest trade fair in the Bergisches Land region – the local ice rink – is the premises of Marmor Pauly, which has been working in natural stone since 1871. “A knife doesn’t always have to be made of steel,” thought owner Armin B. Pauly, architect and graduate civil engineer.

And it doesn’t have to be handy either: together with the self-employed stone sculptor Hartmut Hegener, he created a butter knife sculpture on a scale of 10:1 to place in front of the entrance to the trade fair and point out that, in addition to the proud steel tradition, there are also many years of stone masonry activity. The knife measures 2.30 meters with a handle made of polished Anröchter Grünstein, a calcareous sandstone from the Soest region. The finely ground blade made of “Belgian granite”, the Belgian equivalent of Aachen bluestone, was made with ground-in fiberglass reinforcement. The contrast between the darker blade and the lighter handle is enhanced by the different cut, which makes the Belgian bluestone appear particularly dark. For installation, the artwork was anchored on a base stone made of black Swedish in the area of the main entrance.

Art exhibition flanked the trade fair

Because Pauly is a cosmopolitan, art-loving person and the “knife made of natural stone” contains a wink at other materials, an art exhibition with a wide variety of materials was held on his factory premises opposite the trade fair from June 8 – 10, 2018 – in addition to works by sculptors and painters, including steel sculptures by Thomas Röthel and Stephan Mensler. This created a bridge between materials and street sides.

After the event ended, however, the city of Solingen showed no interest in keeping the potential postcard motif in front of the ice rink – so the monstrous knife will soon find a new home with a well-known steelware manufacturer.

Museum of 1000 Places

Building design

Germany

The Federal Republic of Germany has been commissioning art in architecture for its buildings in Germany and abroad since 1950. Over the decades, around 10,000 works have been created. Natural stone works are also included. Now the Federal Office for Building and Regional Planning (BBR) is making the works of art digitally accessible – via the online platform “Museum of 1000 Places”. In conversation with Dr. Ute […]

Ute Chibidziura: It’s an online presentation for the federal government’s art in construction. In other words, art that is created in connection with construction projects. Since 1950, art in construction has been realized in federal buildings, so that over the years an internationally unique stock of post-war art has been created, which includes the works of many well-known artists in all genres and techniques. We wanted to present this collection of art, which is spread across hundreds of properties in Germany and abroad, in a bundled form.

Many works of art are not accessible to the public …

One peculiarity of art in architecture is that it is tied to the building and is realized in places that are only accessible to a few people for security reasons or, like embassies, are in geographically remote locations. As a result, there are numerous works of art that are little known or have fallen out of sight over the years. With the “Museum of 1000 Places”, we can bring them back into the public eye and make them accessible to the general public.

Why in the form of a virtual collection?

The collection comprises around 10,000 works of art in total. We couldn’t present them in an illustrated book or in an exhibition – that would go beyond any organizational and personnel framework. The “Museum of 1000 Places”, on the other hand, is structured in such a way that works of art can be added bit by bit and the museum grows continuously. In addition, changes can be made to the content at any time. Art in architecture would be difficult to show in a traditional exhibition anyway, because in order to illustrate its location in the spatial context, you would have to build a model of each room or building and prepare picture galleries and texts for it, which would mean an enormous amount of work for just a few examples. Another advantage of a virtual exhibition is that it is not tied to a specific location, but can be viewed from home via the Internet.

How does the digital museum visitor navigate through the site?

There are several ways to access the art: an intuitive one via the images of the artworks on the homepage, a systematic one via the artworks, artists or locations tabs and one via the free text search. Within the artworks, you can sort by technique or context of use.

What information can you find when you call up a work of art?

You will find detailed information about the artwork in its architectural context, about the building and the property, and of course about the artist. It explains the artist’s career, the focus of their work and where else they have realized art on buildings. All information and photos relating to a work of art are stored in the form of a PDF that can be downloaded.

How does the virtual museum build a bridge to the physical world?

The museum indicates whether a work of art is freely accessible or at least open to the public, so that you can also view Kunst am Bau as part of a Sunday stroll. In addition, all works of art will gradually be equipped with a QR code that can be used to link to the “Museum of 1000 Places” to obtain detailed information about the work of art.

Which works of art are made of natural stone?

One important example is the “Rising Phoenix” by Hannes Schulz-Tattenpach on the Old House of Representatives in Bonn. This work of art made of limestone was the first work to be selected and commissioned after the Second World War as part of an open art-in-architecture competition. The phoenix rising from the ashes was intended to refer to the situation of the Federal Republic of Germany at the time, which had to reorganize itself as a democratic state after the war. The motif was still considered so apt in 1974 that it was used as a stamp on a special postcard issued by Deutsche Post to mark the 25th anniversary of the Federal Republic.
