- AI-based forecasts challenge traditional planning paradigms and open up new perspectives for architecture and urban development.
Vacancy as an Urban Reality—and an Underestimated Problem
Anyone who thinks of vacant offices in Frankfurt or deserted shopping streets in downtown Munich when the topic of vacancy comes up is, at best, only scratching the surface. Vacancy has long been a citywide—indeed, a societal—problem. In Germany, Austria, and Switzerland, the numbers have been rising for years—not only in traditional problem areas but increasingly in major cities as well. The reasons are varied: from the shift to remote work to the transformation of the retail sector and demographic changes. The fact is: Every unused building is a temporary investment wasteland, a climate killer in the making, and a social time bomb that destabilizes neighborhoods. The traditional solutions? They hardly work anymore. Rental incentives, temporary uses, renovation strategies—all well and good, but usually too slow, too piecemeal, and not data-driven enough. Most cities manage vacancies based on wishful thinking: If you report a vacancy today, you might get a solution in two years. That’s how government works. But cities that want to keep up with the times need forecasts—and in real time.
The real problem: Vacancy isn’t just an economic issue, but an environmental and social one as well. Every vacant space consumes energy, generates emissions, and leads to a host of problems—from vandalism to the loss of urban vitality. In Austria, for example, according to recent studies, nearly 20 percent of office space is used inefficiently; in Switzerland, the figure is still around 13 percent. Germany falls somewhere in between, depending on the region. Yet the public debate on this issue remains strangely lackluster: Anyone who raises the issue of vacancy quickly gets bogged down in endless discussions about bureaucracy, property rights, and jurisdictional responsibilities. The question of how vacancy can be managed more intelligently, quickly, and sustainably is usually sidelined—out of fear of losing control or simply due to a lack of technical understanding.
This is exactly where digitalization comes into play. After all, tools have long been available that make vacancy rates not only visible but also predictable. Sensors, digital twins, big data—it’s all there. But how do we make the leap from a static list of vacant properties to a dynamic forecasting model? The answer is clear: with artificial intelligence that generates actionable recommendations based on data. But to get there, architects, developers, investors, and local governments must be willing to question their own understanding of planning—and embrace new, data-driven processes.
Another problem: the approach to vacancy management is highly fragmented across the DACH countries. While Vienna is experimenting with targeted analyses and Zurich is building data platforms for land use, many German municipalities are still stuck with analog “paper tigers.” Vacancy management here is often a side job for overburdened employees at the building department. Those who champion digitalization are viewed with suspicion—the fear of data misuse and loss of control is simply too great. Yet this attitude is an anachronism: Anyone who still manages vacancy “manually” in the age of AI is missing the boat when it comes to the future of urban development.
And so, in many places, vacant properties remain a blind spot—economically, ecologically, and in terms of urban planning. While global metropolises have long relied on digital forecasting models, many cities in the DACH region remain at a standstill. The result: space remains unused, emissions rise, and opportunities are squandered. It’s time for that to change—and radically so.
Forecasting Models Put to the Test: How AI Predicts Vacancy
Artificial intelligence is not a magic wand that can make vacancy disappear at the push of a button. But it is currently the most powerful tool for predicting, managing, and optimizing the occupancy of buildings and neighborhoods. The basic idea: The more data collected on buildings, user behavior, mobility flows, and external factors such as weather or events, the more accurately we can predict when, where, and why spaces stand vacant—and how they could be better utilized. Forecasting models analyze historical occupancy data, combine it with real-time inputs from sensors and IoT platforms, and use this to generate reliable predictions for the future. The algorithms detect patterns that remain invisible to the human eye—such as seasonal fluctuations, sudden drops in usage, or the impact of major events on space demand.
In practice, this results in highly dynamic management models. For example, an AI system for an office district can not only indicate which spaces are currently underutilized but also when that is likely to change. This enables real estate operators to offer flexible leasing models, allocate space to changing user groups, or initiate temporary uses—all guided by data-driven forecasts. Pilot projects are already underway in Switzerland where algorithms detect vacancies in commercial real estate early on and suggest countermeasures. In Austria, AI-supported occupancy analyses are being used in new construction projects to dynamically adjust space requirements and usage concepts. Germany? Still hesitant, but the first innovation districts and smart city projects are relying on similar models.
Technically, the entire system is based on a sophisticated interplay of data sources, machine learning models, and high-performance analysis systems. The quality of the forecasts stands or falls with the data available—the more data there is, the more structured it is, and the more up-to-date it is, the better. Sensors on doors, photoelectric sensors, booking systems, energy consumption data, mobility analyses—everything is factored in. The AI continuously learns, identifies new trends, and adjusts the models accordingly. The key point: With each passing day, the forecasts get better, the recommendations become more accurate, and vacancies decrease.
But technology isn’t everything. User acceptance, data governance, and model transparency are also crucial. Any owner or operator implementing AI must also be able to explain how it arrives at its forecasts. Black-box algorithms without any means of verification pose a risk—both to user acceptance and to legal certainty. This highlights that successful forecasting models are always a matter of communication and governance.
And then there’s the question of scalability. A forecasting model that works in a single building is not yet a solution for an entire city. Integration into neighborhood and urban development concepts, interfaces with other digital systems, and alignment with sustainability goals are the real challenges. Those who cut corners here will, at best, produce attractive dashboards—but have no real impact on vacancy rates.
Sustainability and Resource Efficiency: Why Smart Space Allocation Is More Than Just a Cost Factor
The issue of vacancy is often reduced to an economic level: Vacant spaces cost money, so you have to get rid of them somehow. But that view falls far short of the mark. After all, unused or underutilized buildings are also an ecological disaster. They waste energy and resources and tie up capital that is urgently needed elsewhere. Every square meter of space that is air-conditioned, lit, or cleaned while unused creates an environmental footprint—without adding any social value. Artificial intelligence can be a game-changer here by not only optimizing usage but also managing energy consumption, building maintenance, and opportunities for repurposing.
In practice, this means that AI-supported forecasts can help manage buildings more sustainably, promote the circular economy, and make better use of gray energy. For example, if it is determined that certain office spaces will no longer be needed in the long term, they can be selectively demolished, repurposed, or converted for use in the residential market. Forecasting models help manage these processes proactively rather than merely reacting to them. In Zurich, there are already examples where vacant commercial units are converted early on into coworking spaces or social facilities—guided by data-driven analyses.
Smart space-occupancy models also play a key role in achieving climate goals. Fewer vacant spaces mean fewer unnecessary emissions—and given the ambitious climate plans in the DACH countries, this is not a luxury but a necessity. Forecasting models make it possible to increase space efficiency and better utilize existing buildings, rather than constantly developing new areas. This is true circular economy for space—and a paradigm shift for the construction and real estate industries.
Added to this is the social component. Vacancy is not only a waste of resources but also a symptom of social imbalances. Neighborhoods with high vacancy rates suffer from population outflow, a loss of reputation, and a declining quality of life. Forecasting models can help identify these trends early on and take countermeasures—for example, through temporary uses, cultural interim uses, or the targeted attraction of new stakeholders.
Overall, smart space allocation is more than just a tool for cost optimization. It is key to creating sustainable, resilient, and livable cities. Anyone who views the issue merely as a technical side note has failed to grasp the core of the challenge.
Technical Expertise, Acceptance, and Governance: What Professionals Really Need to Know
Getting started with AI-based forecasting models for space allocation is not a sure thing. Architects, engineers, project developers, and urban planners must embrace new areas of expertise—from data analysis and modeling to the interpretation of complex algorithms. It’s not enough to simply present attractive dashboards. Anyone who truly wants to create added value must understand the data, be able to critically evaluate the models, and confidently assess their impact on planning. This requires interdisciplinary expertise—and a willingness to occasionally set aside traditional routines.
A key issue is data quality. Forecasting models are only as good as their input. Incomplete, outdated, or erroneous data leads to incorrect results—with potentially serious consequences for urban development. That’s why professionals must be able to review and validate data sources and place them in the proper context. It’s not rocket science, but it’s certainly not a task for managers who treat it as an afterthought.
User involvement is another critical issue. Anyone who uses forecasting models without involving those affected risks encountering acceptance issues and resistance. Transparency, participation, and communication are therefore just as important as technical excellence. Even the best algorithms are of little use if they’re developed in an ivory tower and ignored in practice. Successful projects are characterized by their ability to integrate user needs and clearly explain how and why the forecasts are generated.
Governance and data protection are traditionally sensitive issues in the DACH region. Anyone working with personal or sensitive building data must be familiar with and respect the legal framework. Data sovereignty, access restrictions, and transparent decision-making structures are indispensable. In Germany, for example, many projects are never even launched out of fear of misuse or liability issues. This slows down development—and leads to international players moving forward more quickly and boldly.
And finally, there is the question of integration into existing systems. Forecasting models only deliver their full value when they are integrated with other digital tools—such as CAFM systems, BIM platforms, or urban data infrastructures. This requires a technical understanding of interfaces, data formats, and process architectures. Those who rely on siloed solutions get bogged down in minutiae—and miss the opportunity for true innovation.
Debates, Visions, and Looking Ahead: How AI Is Changing the Job Profile
The introduction of AI-based forecasting models for space occupancy is more than just a technical gimmick—it represents a paradigm shift for the entire industry. Architects and urban planners are becoming data curators, process designers, and facilitators bridging the gap between technology and society. Traditional planning paradigms are being challenged: What used to be decided based on gut instinct and experience is now simulated and optimized using data. This sparks not only enthusiasm but also fears. The debate between tech enthusiasts and skeptics is in full swing. Critics warn of algorithmic bias, the devaluation of human expertise, and the danger that cities will degenerate into technocratically controlled systems. Visionaries, on the other hand, see an opportunity for more livable, efficient, and sustainable cities.
An international comparison reveals that while major cities like Singapore, London, and New York already use AI-powered forecasting models as standard tools, there is still a great deal of reluctance in the DACH countries. The reasons? Fear of losing control, a lack of data infrastructure, legal uncertainties, and a certain degree of skepticism toward technology. But the pressure is mounting—not least due to international role models and the need to use resources efficiently.
The debate over the role of AI in planning is also a question of governance. Who decides what data is collected, how the algorithms are trained, and which forecasts are relevant? This calls for new forms of collaboration—between government, business, research, and civil society. The architecture and planning sector faces the challenge of repositioning itself: as a bridge-builder between technology and urban society, as a facilitator of complex change processes, and as a shaper of digital urbanity.
And then there is the question of vision. In the future, forecasting models could not only combat vacancy rates but also enable entirely new forms of use—from flexible neighborhoods to adaptive housing models to dynamically managed mixed-use districts. The tools are there, the models are getting better and better, and the opportunities are right in front of us. What’s missing is the courage to actually shape this future.
Conclusion: Anyone who believes that AI will render the work of architects, urban planners, and real estate experts obsolete has failed to understand the issue. It makes their work more challenging, more data-driven, and—with a little luck—more effective as well. The future of space utilization is smart, sustainable, and digital. Those who don’t jump on board now will be left behind.
Conclusion: Rethinking Vacancies—Using AI to Combat the Waste of Space
Artificial intelligence is not a magic bullet for vacancy, but it opens up entirely new possibilities for using urban spaces more efficiently, sustainably, and in a socially balanced way. Forecasting models for space occupancy are the next logical step for anyone serious about digitizing urban development. They require technical expertise, the courage to embrace change, and a new understanding of planning. Those who embrace this today will shape the city of tomorrow—data-driven, flexible, and resource-efficient. Those who continue to rely on analog routines will be left behind by reality. The future belongs to those who not only own space but also manage it intelligently and fill it with life. Anything else is vacancy.
