Energy Efficient Data Center Campus Being Built by Green in Zurich Area


In Dielsdorf, a town close to Zurich in Switzerland, Green is developing its significant Zurich Metro Campus data center project on a plot of land larger than 46,000 m2. In addition to a business park with multiple office buildings, it consists of three high-performance data centers (M, N, and O) for cloud providers and businesses. Major clients moved into the first data center in December 2022, and it began operations last week.

The next stages have already been planned. In terms of performance, connectivity, security, and energy efficiency, data center M is among Switzerland’s most cutting-edge data centers. “Data center M is a flagship project in terms of energy efficiency and sustainability,” said Green COO Andrea Campomilla, who is responsible for the company’s data centers.

Around 80,000 servers can fit in the 5,600 m2 of useable data center space, which also enables high-density computing, which is particularly desired by public cloud providers (hyperscalers). High power density was a consideration while designing the data centers, and local teams at Green worked to maximize energy efficiency.

Low PUE, Using Waste Heat

Architecture, material selection, interior design, system layout, and cooling strategy were all optimized for Green’s latest data center development. The latter makes sure that ambient air is used for cooling wherever feasible instead of mechanical and energy-intensive methods. The sustainability idea is completed with photovoltaic systems on the building’s roof and the usage of renewable energy sources. Green would achieve top scores, with a PUE (Power Usage Effectiveness) value close to 1.

The use of waste heat is also considered exemplary. The planned district heating system will allow more than 3,500 households as well as commerce and industry in the region to benefit from climate-neutral heating and process heat from data center M.

The expansion’s subsequent phases have been established: the south office building’s civil engineering construction began in January 2023. Green will utilize a portion of the about 3,000 m2 of office space to ensure the efficient functioning of the high-performance data centers on-site and to keep in touch with clients. It will be rented more office space.

In Switzerland, Green has expanded its expansion and innovation agenda. The building of data centers N and O comes next. Construction will start as early as 2023 due to demand.

“We are constantly investing in innovation and are growing in a customer-oriented and sustainable way,” said Roger Süess, CEO of Green.
