IT-label versus energy label: what is the difference, and why are both essential?

Two labels, two dimensions of quality

In the real estate world, the energy label has become indispensable. It partly determines the lettability, value and sustainability of a building. But in an economy driven by data, cloud and AI, a second label is emerging that is growing in relevance: the IT-label. Although both labels say something about the quality of a building, they measure entirely different: yet complementary, aspects.

The energy label provides insight into a building's energy performance: insulation, heating and cooling, ventilation, energy consumption and use of renewable energy. The goal is clear: improve energy efficiency, reduce CO₂ emissions and make buildings more sustainable. A good energy label lowers energy costs, increases property value, improves lettability and supports regulatory compliance.

What does the IT-label assess?

The IT-label assesses a building's digital readiness. This goes beyond the physical quality and security of IT infrastructure alone. In addition to matters such as access control to server rooms, fire safety, power supply (UPS and backup power), climate control and cabling protection, the IT-label also looks at continuity provisions and redundancy, risk management, suitability for cloud and AI applications, connectivity structure, organisational governance and access policies, monitoring and management processes, and the future-proofness of the infrastructure as a whole.

Where the energy label measures energy performance, the IT-label measures digital resilience and continuity. It takes an integrated view of a building's digital foundation: technical, organisational and strategic.

Why both labels are indispensable

Sustainability is no longer optional. Buildings with poor energy performance may in some cases no longer be let, are less attractive to tenants, have higher operating costs and face the risk of depreciation. The energy label remains a fundamental pillar of real estate.

At the same time, digitalisation is changing how buildings are used. Organisations depend on cloud applications, VoIP telephony, AI systems, IoT solutions and data-driven processes. Without stable power, proper cooling, redundant connectivity and clear management processes, an organisation can grind to a complete halt. A building can be energy-efficient yet digitally vulnerable. An A+++ energy label says nothing about the security of the server room, the availability of backup power, the presence of redundant connections, the governance of IT access, or suitability for AI-driven applications. That is where the IT-label fills the gap.

Stronger together: for landlords, tenants and investors

The future demands buildings that are energy-efficient, achieve CO₂ reduction, guarantee digital continuity and are suitable for AI, IoT and smart applications. The energy label and the IT-label complement each other. A modern building must be green, intelligent, secure and continuously available.

For landlords, tenants, investors, property advisers and insurers, it is increasingly important to demonstrate both sustainability and digital robustness. The energy label reduces environmental impact. The IT-label reduces digital and operational risk. Together they strengthen property value, market position, continuity, insurability and attractiveness to modern tenants.

A building without a good energy label is not sustainable. A building without a good IT-label is not digitally resilient. In a world where sustainability and digitalisation go hand in hand, both labels are not a luxury: they are a necessity.
