The property professionals’ solution

Once the preserve of IT engineers, data centers are now at the heart of a very real estate-related debate: location, land, permits, power supply, efficiency, risk of obsolescence. In Switzerland, the momentum is building, driven by the cloud, the rise of AI and the issue of data sovereignty. For real estate professionals, these “black boxes” are becoming a segment to watch closely, provided they understand the rules, which are very different from those of traditional real estate.

1) Why demand is exploding and why it is changing

Since 2010, the shift to the cloud has changed demand: we store less “at home” and more in shared infrastructure. At the same time, AI is increasing the pressure on computing and hosting capacity. The result is that demand is increasing, but the market is becoming more polarized.
A key point for investors and developers: not all data center space is the same. Historic enterprise centers may become vacant or obsolete, while infrastructure adapted to the standards of the major operators (hyperscale cloud providers such as AWS, Microsoft Azure or GCP) is where the value is concentrated. Add to this the continuous technological evolution: at the same data capacity, the need for racks and m² may decrease, which makes the issue of obsolescence particularly important.

2) Switzerland, a “data safe” and Zurich as a hub

Switzerland combines several sought-after attributes: political stability, a legal framework that is reputed to be favorable, connectivity, and reliable networks. In this landscape, Zurich stands out as the main hub: presence of the finance/tech sectors, connectivity density, ecosystem effect, and the presence of cloud regions. The figures available for the colocation segment show a net increase in space, with a marked concentration in the canton of Zurich.
For professionals, this concentration has a double effect:

• location premium in the areas that are really “plugged in” (network, redundancy, proximity to customers);
• scarcity of land around the optimal locations, which increases the value of well-located land and existing assets.

3) Returns: why it attracts and why it worries

Data centers are often described as one of the most profitable asset classes in Europe. The narrative is appealing: long leases (often 10-20 years), creditworthy tenants, indexation, structural demand.
But the return/risk equation is more complex than for office or residential assets:

• technological risk (faster obsolescence, changing technical requirements);
• energy risk (available capacity, cost, connection times, volatility);
• liquidity risk (rare assets, infrequent transactions, high entry ticket);
• operational risk (hybrid asset requiring specific know-how).

This cocktail explains why, in Switzerland, part of the market is driven by specialized international capital, while local institutional investors remain cautious.

4) Land and electricity: the two bottlenecks

This is where real estate becomes very concrete again. Building a data center is not just a matter of finding a plot of land in an industrial area:

• it often requires a large, contiguous surface area;
• a high-performance fiber optic connection;
• and above all, secure and redundant electrical power.

The scarcity of suitable land in Switzerland and its fragmentation make it difficult to establish a data center, especially for large projects. Operators with high financial resources can outbid other uses (light industry, logistics), which changes the competition for land in industrial areas.

5) Local acceptability: a real estate issue in its own right

For a municipality, the equation is ambivalent. Data centers are often perceived as:

• imposing volumes that are not very “urban” (blind facades, security);
• not creating many jobs in relation to the land area;
• not always very tax-generating if the operator is not domiciled locally.

This leads to political and citizen resistance. However, when the land use and urban planning rules are respected, the market dynamics (and the purchasing power of the operators) weigh heavily in the final decision.

6) Regulation and sustainability: from PUE to waste heat

Recent data centers are subject to energy efficiency requirements, including the PUE (Power Usage Effectiveness) index, which measures the ratio between the total energy consumed and the energy actually used by IT. The lower the PUE, the more efficient the site.
Structuring trend: the valorization of waste heat. Some authorities are imposing or encouraging its integration into heating networks (District Heating), which can improve acceptability and sustainability, but also add costs and design constraints.

7) Real estate opportunities: new construction, colocation, redevelopment

The market is segmenting:

• hyperscale / large operators: looking for large, vacant sites, industrial strategy, high technical requirements;
• colocation: can be located in business areas, sometimes in existing buildings (including basements);
• redevelopment: dismantling of obsolete sites and reuse of technical “boxes” for other uses (or reconstruction).

For developers and investors, redevelopment is an interesting angle: it transforms a risk (obsolescence) into an opportunity, but requires a careful reading of costs, standards and local market needs.

8) What professionals should check before getting involved in data centers

If you have to remember one thing: a data center is as much an infrastructure asset as a real estate asset. Before making any decision, a specific analysis framework is required:

• Technical location: connectivity, redundancy, proximity to customers, exposure to risks.
• Energy: available power, connection time, cost, contract, security.
• Specifications: cooling capacity, density, modularity, scalability.
• Regulation/sustainability: PUE, local requirements, waste heat, future constraints.
• Tenancy risk: single-tenant vs. multi-tenant, quality of leases, indexation.
• Obsolescence: capex plan and upgrade strategy.
• Liquidity: market depth, type of buyers, ticket size.

Conclusion

Data centers are no longer a peripheral subject: they are reshaping the commercial real estate landscape at the intersection of land, energy and technology. The potential for returns is real but it comes with barriers to entry and risks that traditional real estate is not used to carrying at this level. For professionals, the challenge is not just to “follow the trend,” but to understand what type of asset, what model (colocation, hyperscale, conversion) and what level of exposure to risk are really compatible with their strategy.
