Planned

Green's Campus ZRH2, marketed until 2025 as Metro-Campus Zurich, sits on Niederhaslistrasse in Dielsdorf's industrial zone. It lies beside Dielsdorf S-Bahn station, about 15 km north of Zurich. It is Green's second Swiss campus after Lupfig (Campus ZRH1).

Land and buildings

The campus covers about 46,000 m² (11.4 acres) of former farmland on cadastral parcels 2165 to 2169.
Green announced the CHF 500 million project in January 2021 and broke ground the same year.
The master plan holds three four-storey data center modules and three office buildings for a business park. It also includes a 200 m underground garage and a public park with a pond.
Implenia is the general contractor. MBA Projektmanagement manages the project, eins architekten designed it and Emch+Berger engineered the civil works.
The south office building's facade uses 100% recycled aluminium, a first in Switzerland.

Ownership

Green Datacenter AG develops and operates the campus.
InfraVia bought Green from Altice in 2018. IFM Investors' Global Infrastructure Fund bought Green Group AG from InfraVia, and the deal closed on 30 October 2025.

Power and cooling

EKZ built a new substation, Unterwerk Dielsdorf, on the campus. It connects to Axpo Grid's 110 kV Regensdorf-Eglisau line and is designed for three 50 MVA transformer feeds. The first stage has two. EKZ spent about CHF 14 million on it.
EKZ's Regensdorf and Steinmaur substations give a second, independent supply.
Avesco supplies 27 Cat diesel generator sets for the full campus, nine per data center. Each has SCR exhaust cleaning with AdBlue. The generators can also support Swissgrid's tertiary reserve.
Cooling uses ambient-air free cooling on up to 300 days a year, with 24 chillers. Green offers hybrid air and liquid cooling for high-density racks. Rooftops carry photovoltaic panels.
Waste heat feeds Energie 360°'s Dielsdorf energy network through a heat center on the campus. At full build the campus can heat about 11,500 households in six municipalities.

Connectivity, customers and awards

The campus is carrier-neutral. It offers about 50 carriers, SwissIX access and direct links to the major public clouds.
Certifications include ISO 27001, ISO 22301, ISO 27701, PCI DSS and SOC 1 Type 2 / ISAE 3402.
Customers include hyperscale cloud providers, banks, insurers and hospitals.
Data Center M won the DCS Awards 2023 "New Design/Build Project of the Year". The waste heat project won at the Data Cloud Global Awards 2024.
