An energy-efficient building starts with good IT

Picture a modern office. Smart lighting that adjusts to occupancy, climate control that adapts per zone, sensors that measure air quality and an energy management system that maps consumption. On paper, this is a smart building. All the technology is present.

Do you want to know how smart systems can help towards a better energy label? Read Improve your energy label? Start with the digital foundation of your building.

Yet it does not function as intended. The network connection is unstable, the cabling is outdated, sensors communicate irregularly and no one knows exactly how the digital infrastructure is set up. The technology is there, but the digital foundation is missing. You can install the best software, but without good infrastructure the building remains digitally stuck in first gear.

This brings us to the central idea of this article: a smart, energy-efficient building starts with a solid digital foundation. As energy performance becomes more dependent on technology, the quality of the IT infrastructure indirectly determines how well a building actually performs.

From energy-efficient building to smart building

Real estate is evolving from relatively static buildings into buildings where installations constantly communicate with each other. Where a thermostat and a light switch once sufficed, climate systems, lighting, occupancy detection, energy management, charging points, solar panels, access control and security now communicate with each other through a central building management system.

All these systems generate and use data. Sensors measure, installations report and software adjusts. Predictive maintenance prevents faults before they occur. This means that not only people consume increasingly more data, but the building itself becomes a major data consumer.

That data consumption has now become a value in itself. The smarter a building, the more data streams run through it permanently. And every data stream requires an infrastructure that can carry that stream reliably.

Without digital infrastructure, no good IoT

IoT stands for Internet of Things: physical devices that exchange data over a network. In real estate, these are the sensors, meters, cameras, charging points and installations that together make a building smart. To function, these devices need to be able to send, receive and process data.

A number of things are needed for this. Think of reliable internet connections, fiber optic cable all the way into the building, good internal cabling, professional Wi-Fi with full coverage, network segmentation, solid technical rooms and redundancy so that one connection does not bring down the entire building. On top of that come monitoring, cybersecurity and clear agreements about who is responsible for what.

The role of MER and SER rooms as the heart of the building network is often underestimated in this respect. If this foundation is missing, smart building applications may function less reliably. The rule of thumb is simple: without good IT infrastructure there is no reliable IoT.

IT and energy increasingly go hand in hand

Energy optimization is increasingly driven by data. A building must first be able to measure before it can properly control. Without reliable measurements, an installation is essentially operating blind.

Sensors register, for example, temperature, air quality, occupancy, energy consumption, occupancy rate and the performance of installations. With that data, heating, cooling, ventilation and lighting can be controlled more precisely. A room that is empty does not need to be fully conditioned.

This creates a logical chain:

• IT infrastructure enables communication
• Communication delivers data
• Data delivers insight
• Insight enables smart control
• Smart control leads to energy optimization

Each link depends on the previous one. If the first is missing, the rest falls away. This is precisely why digital infrastructure indirectly becomes so decisive for a building's energy performance.

A building that cannot measure reliably cannot control effectively. And what is not controlled is rarely optimal.

The energy label shows one side of the building

The energy label is an important and widely recognized indicator within real estate. It provides insight into the energy performance of a building and has helped the market make sustainability concrete and comparable. That value is beyond dispute.

At the same time, a modern building needs more infrastructure than energy provisions alone. Alongside electricity, water and heating, digital infrastructure has now become almost a fourth utility. An organization can hardly function today without a reliable connection.

Compare it to the classic utilities. A building without power or water is unusable. A building without a reliable digital connection is increasingly becoming so as well. Yet that layer is still rarely mapped systematically, even though internet has become the lifeline of commercial real estate.

That is why the IT-Label exists

The IT-Label makes the digital delivery level of commercial real estate transparent. Where the energy label describes how a building handles energy, the IT-Label describes what a building can handle digitally.

The IT-Label looks at, among other things, internet connections, fiber optics, internal cabling, Wi-Fi, MER and SER rooms, redundancy, network structure, digital security, access control, monitoring, smart building infrastructure, scalability and future readiness. Together these components form a picture of digital quality.

The goal is not to make technology more complicated, but rather the opposite. The IT-Label translates technical reality into understandable information and makes visible what is often still invisible. The classification ranges from IT1+ PREMIUM for fully equipped, AI-ready buildings to IT5 SHELL for a building where the digital infrastructure still needs to be fully developed. A classification is not a judgment, but a factual representation of what is present.

From energy label to complete delivery level

Real estate should ultimately not be assessed on one single aspect. A modern user wants to know how energy-efficient, sustainable, comfortable and secure a building is, and whether it is digitally future-proof.

The energy label and the IT-Label do not replace each other. They complement each other and together give a more complete picture of the actual delivery level. The energy label tells how the building handles energy. The IT-Label tells what the building can handle digitally. Both are needed to make a responsible choice when buying, renting or renovating.

These two worlds reinforce each other. An energy-efficient building with a strong digital foundation can monitor, adjust and improve its own performance. Together, the labels show whether that interplay is actually possible.

AI only makes this more relevant

Users' data consumption is rising faster than many buildings were designed to handle. Cloud software, AI applications, video conferencing, real-time data, smart sensors and automation all demand bandwidth, stability and low latency.

That is why the question is increasingly: is your office actually AI-proof? A building that seems digitally sufficient today may fall short within five to ten years. The digital lifespan of a building is shorter than its structural lifespan, and AI is only widening that gap.

The IT-Label therefore functions as a digital MOT test for real estate: a snapshot that gives owners and users insight into what is present, what is missing and what can be improved. This makes an abstract concept such as an AI-proof office concrete and testable.

Practical by design, not meant for the drawer

The IT-Label is deliberately designed to be practical. Not a complicated technical report that disappears into a drawer after delivery, but understandable information that property owners, asset managers, property managers, tenants, brokers, project managers and IT parties can actually work with.

The greatest benefit lies in identifying problems in time. Preferably before the lease transaction, renovation or relocation, rather than only once an organization has already moved into the building and runs into limitations. A preliminary inspection beforehand prevents surprises afterward. The underlying idea: investigate first, then build, then connect.

What it concretely delivers for you

• Insight into digital quality before you sign or invest
• A shared language between owner, tenant and supplier regarding responsibilities
• A basis for targeted investment instead of repairing after the fact
• Assurance that your sustainable installations can actually function reliably

Take the next step

The energy label and the IT-Label go hand in hand. A building can be energy-efficient, but without good digital infrastructure it becomes increasingly difficult to let all that smart technology actually function optimally. That is why future-proof real estate starts with insight into both worlds.
