Germany's climate ambitions for the building sector are usually discussed in the language of insulation, heat pumps and energy certificates. Far less attention goes to a question that every architect, building owner and site manager eventually runs into: what happens when the push for energy efficiency collides with fire protection law? According to recent doctoral research by Dr. Dejan Cargnelutti, an alumnus of the European Institute of Management (EIM), that collision is not a side issue. It sits at the centre of whether Germany's construction sector can deliver safe, climate-aligned buildings at all, and the technologies of the Fourth Industrial Revolution (4IR) may be the most realistic way through it.
His dissertation, 4IR Technologies within Germany's Construction Sector to Meet Fire Protection Standards and International Climate Objectives, is independently published and indexed on ProQuest. It offers a rare practitioner-level view of an industry that is often described as one of the slowest to digitalise, yet is now expected to transform faster than almost any other.
A Sector Caught Between Two Mandates
Construction in Germany operates under two mandates that do not always pull in the same direction. On one side are climate and energy efficiency objectives that demand deep renovation of the existing building stock. On the other side are fire protection standards that exist for a non-negotiable reason: protecting lives. Every new insulation layer, every change to a façade, every alteration of escape routes or building services has potential consequences for how a building behaves in a fire.
Cargnelutti's research starts from a problem that scholars have repeatedly highlighted: construction professionals in Germany lack sufficient industry-specific knowledge about how digitalisation, often summarised as "Construction 4.0", can actually increase operational efficiency and productivity in their daily work. The technologies exist. What is missing is a grounded understanding of how they help professionals meet concrete regulatory demands.
To make that understanding tangible, the study anchors its analysis in a specific legal reference point: the Bavarian fire protection law of 1 August 2023. Rather than discussing digitalisation in the abstract, the research asks how 4IR technologies can raise productivity in a real regulatory context where safety and climate goals must be reconciled.
How the Research Was Built
The dissertation follows a qualitative multiple-case study design based on 16 interviews with construction industry experts, supported by reflective field notes and archival data. Its conceptual framework combines three ideas that, taken together, describe the full arc of a building's existence:
- Construction 4.0 (Gledson et al., 2024), which frames how digital and automated technologies reshape construction processes.
- Building lifecycle management (Ustinovičius et al., 2015), which treats a building as an asset to be managed from design through operation to renovation.
- Building information management (Wang et al., 2020), which focuses on how information about a building is created, structured and used across stakeholders.
This combination matters. Fire protection is not a one-time approval issued at the end of a project. It is a property of the building that has to be preserved through every renovation and every change of use. A framework that links digital construction methods to lifecycle and information management is therefore well suited to the question at hand.
Sixteen Themes, Six Fault Lines
The thematic analysis of the interviews produced 16 themes, organised into six coding categories: digitisation in German construction, demand for 4IR technologies, challenges of adopting 4IR for fire protection, applications of 4IR for fire protection, challenges in making existing buildings energy-efficient, and the innovation needed to meet safety and climate objectives. Read together, the findings form a clear diagnosis.
Digitisation is still incomplete. The experts confirm that the sector lags behind other industries: data is not stored fully digitally, paper plans are still in use, and there is no standardised file format that all software providers can fully process. Even open BIM exchange formats such as IFC do not cover every attribute a project needs, so information breaks down between tools and on site. Where data is digital and accessible, productivity rises because time is saved and errors are reduced.
Demand is high, but people are the bottleneck. Practitioners want 4IR technologies. What holds them back is difficult digital access to as-built plans, insufficient training and resistance from employees, particularly when new tools are introduced without proper support. The dissertation notes that companies trying to digitise on their own, without shared platforms, often train their staff insufficiently. It also cites industry data showing that annual productivity growth in construction has stayed below 1% for two decades, well below the global average.
Fire protection faces a regulatory patchwork. Building materials, for example insulation used in energy renovation, must meet strict fire protection criteria, and 4IR applications are not yet accepted as standard in fire protection practice. In addition, building and fire protection rules in Germany are set separately by each federal state. The experts see a uniform national standard as a key accelerator for the use of 4IR technologies.
The applications are already tangible. Participants see clear value in digital fire alarm systems, AI-supported temperature analysis of buildings, and self-learning systems that detect building defects and fire risks early. Digital twins, IoT sensors and machine learning are named as tools for lifecycle management and faster alerting.
Existing buildings are the hardest case. Germany has millions of buildings that must be renovated to meet CO₂ reduction targets. The study finds a lack of both acceptance and investment in 4IR technologies for modernising this stock. Substantial public and EU funding is available for energy-efficient renovation, but progress in applying advanced digital tools remains insufficient.
Innovation culture is missing. The experts agree that IoT, AI and big data can significantly improve the sector's contribution to climate targets. But the lack of systematic innovation development and an established innovation culture remains a central challenge.
What Companies Should Do
The dissertation translates these findings into recommendations for practice:
- Invest in digital planning and management tools, IoT and sensor technologies, cloud solutions and virtual reality, which helps identify problems in the planning phase before they occur on site.
- Make training continuous. Training programmes need regular updates to keep pace with technology, and ongoing training also reduces fears associated with change.
- Secure senior management commitment to digitalisation, both on site and in the office, so that employees develop a more open attitude towards digital change.
- Cooperate with universities and research institutions to develop new protocols, data formats and solutions tailored to construction and fire protection.
- Push for uniform standards, including harmonised building and fire protection rules across federal states and interoperable data formats.
Why This Matters Beyond Construction
At first glance, a dissertation on fire protection and 4IR technology might look like a niche engineering topic. It is, in fact, a management study about one of the most common leadership challenges of the coming decade: how to implement technology in a regulated industry where errors are not merely expensive but dangerous.
Three lessons transfer well beyond construction sites. Regulation is a design constraint: digital transformation only creates value when it is mapped against the rules organisations must actually meet. Standards come before scale: without shared data formats and harmonised rules, every new tool creates another island. And technology adoption is a people project: training, leadership commitment and addressing employees' concerns decide whether investments pay off.
The Practitioner-Researcher Advantage
Cargnelutti's dissertation illustrates a broader pattern in EIM's doctoral portfolio. Many candidates are working professionals who bring a live problem from their own industry into their research. Instead of studying a field from the outside, they investigate questions they encounter every day, and they return to their organisations with evidence that can change how decisions are made. Cargnelutti himself is a case in point: as his EIM profile shows, he combines senior leadership experience in building technology, IT and fire protection with a certification as a fire protection expert, and today teaches and researches at EIM.
This is the model behind EIM's Doctor of Business Administration (DBA), a professional doctorate designed to apply advanced research directly to business challenges, strategy and innovation. For professionals whose interest lies more deeply in technology itself, such as digital construction methods, building information systems or the data architectures behind them, the PhD in Computer Science and Engineering offers a research-driven route into the technical side of transformation.
Leaders who want to build the management foundation first, particularly in the energy transition, can start with the MBA in Renewable Energy Management, which focuses on the strategic and operational questions behind the shift to a low-carbon economy, including the energy performance of the built environment.
Part of a Verifiable Research Record
Cargnelutti's work is one of a growing number of EIM doctoral dissertations that are publicly indexed and can be checked by anyone. The EIM Research Institute places it in the "Digital Transformation & AI" pillar of its analysis of 19 doctoral dissertations. EIM has also outlined why this external verification matters for prospective candidates in its overview of dissertations powering the EIM Research Institute. A full list of published alumni dissertations is available on the EIM student outcomes page.
Conclusion
Germany will not meet its climate objectives for buildings by insulating its way there alone. Every renovation must also keep people safe, and the regulatory frameworks that guarantee that safety are becoming more demanding, not less. Dr. Dejan Cargnelutti's research makes a clear case that the technologies of the Fourth Industrial Revolution are not a futuristic add-on to this challenge but a practical tool for reconciling safety and sustainability, provided that the industry builds the knowledge to use them well.
For professionals who see similar tensions in their own sector, the path from operational frustration to research-backed answers is shorter than it may appear.
