What is PropTech and why is good IT infrastructure the foundation?

The real estate sector is undergoing a fundamental transformation. Where buildings were once assessed purely on location, construction quality and energy performance, technology now plays an increasingly dominant role. Under the banner of PropTech - a portmanteau of Property and Technology - all digital innovations fall that make real estate smarter, more sustainable and more attractive for tenants and owners.

But there is a paradox in the PropTech revolution: the more advanced the technology, the greater the dependence on the underlying IT infrastructure. A building that wants to benefit from smart systems needs a digital backbone that meets high standards. That is precisely what the IT-label maps out.

The four pillars of PropTech

PropTech is not a single technology, but a broad ecosystem of innovations. To keep it clear, we distinguish four main categories:

1. Smart building systems

This is the most visible layer of PropTech. Think of digital access control where employees enter with an app or pass, IP security cameras that monitor live via the cloud, smart climate control that responds to occupancy and outdoor temperature, and energy management systems that track consumption in real time. All these systems communicate via the internal network and depend on stable, fast connectivity.

2. Smart energy

The energy transition and PropTech go hand in hand. Charging stations for electric vehicles require intelligent load balancing via the network. Solar panels are linked to energy management systems. AI algorithms analyse consumption patterns and adjust systems to minimise waste. All of this requires an IT infrastructure that can continuously process and transmit data.

3. Data and analytics

PropTech makes buildings measurable. Occupancy sensors record how many people are present where and when, providing input for workplace management and cleaning schedules. Predictive maintenance systems analyse wear patterns of installations and predict when maintenance is needed - before a breakdown occurs. Data analytics increases efficiency and reduces costs, but requires robust network connections and secure data storage. Read more about smart building technology in our knowledge base.

4. Digital user experience

Modern tenants expect more than four walls and a roof. They want a building that works like a service: an app to reserve meeting rooms, smart lighting that adapts to their work rhythm, and a digital platform that manages facilities. PropTech makes this possible, but requires reliable wifi coverage in every corner of the building. See what tenants need to know when choosing office space.

PropTech is not the future of real estate - it is the present. Buildings that do not invest in digital infrastructure now will become unrentable tomorrow.

The role of AI in PropTech

Artificial intelligence strengthens PropTech on all fronts. A climate system that learns from occupancy patterns and preheats the building at the time employees typically arrive saves energy without reducing comfort. Cameras with image recognition can detect suspicious situations and automatically send a notification. Energy management that optimises based on weather forecasts and energy prices significantly reduces costs.

All these AI applications have in common that they process and transmit large amounts of data. They require low network latency, sufficient bandwidth and secure connections. A building that wants to benefit from AI-driven PropTech needs an infrastructure designed for this purpose. This is what we call AI-proof real estate: buildings that are technically prepared for the requirements of intelligent systems.

Why IT infrastructure is the foundation of everything

This is the crux of the PropTech discussion. Many building owners invest enthusiastically in smart systems without having the underlying infrastructure in order. The result: systems that respond slowly, fail under peak load, or are vulnerable to cyberattacks.

A well-functioning PropTech ecosystem requires at minimum:

• Fibre optic connection with sufficient capacity for all connected systems
• Structured cabling (Cat6a or higher) to all workstations and technical rooms
• Full wifi coverage in all zones, including garages, stairwells and outdoor areas
• Redundancy so that failure of one connection does not bring down the entire system
• Cybersecurity that protects smart systems from external attacks

The IT-label as a label for PropTech readiness

The IT-label was developed to address precisely this issue. Just as an energy label makes clear how energy-efficient a building is, the IT-label makes clear how well the digital infrastructure is set up.

The assessment covers all relevant aspects: the quality of the internet connection, the state of the cabling, wifi coverage, the presence of emergency power supplies, and the degree of network security. Based on this, a building receives a score from IT1 HIGH PERFORMANCE to IT1+ PREMIUM, or from IT2 PLUG & PLAY to IT4 CORE & IT5 SHELL for the most advanced properties.

For property owners, the IT-label provides a clear starting point: what needs to be improved to make PropTech applications function properly? For tenants, it provides certainty that the building is ready for the technology their business needs. View the complete label categories to see what each level entails.

A building without a good IT-label is like a car without an engine: the bodywork may look beautiful, but it will not drive.

Conclusion: PropTech is the future, IT is the foundation

PropTech is transforming the real estate sector and offers enormous opportunities: higher rental values, lower operating costs, better user experiences and more sustainable buildings. But all those opportunities remain untapped if the IT infrastructure is not in order.
