Data centre achieves LEED Gold, provides district heat

TeliaSonera’s new 34,000 m2 24MW data centre will achieve LEED Gold performance and deliver district heat to 9,000 Helsinki homes.

A Ramboll team provided management and lead consulting services from feasibility through final handover for the purpose-built data centre, the largest of its kind in Finland. Located in central Helsinki, the new facility complements other TeliaSonera-owned data centres throughout the country, creating asynchronous exchange of data between alternative facilities from the same provider.

Designed to be concurrently maintainable, the data centre can house up to 200,000 servers on 15,000m2 of raised floor space across several floors. The facility delivers up to 24MW of IT power, has a target annualized PUE of 1.12, and achieves LEED Gold standard performance with CEEDA certification.

With two independent power sources derived from the 110kV main utility network, the initial phase of the project will deliver 6MW of IT power. The design is based on a modular growth profile that can be implemented concurrently and delivered seamlessly without interrupting facility operation.

The amount of energy use required to support the IT systems is limited by operating at the extremes of acceptable operating envelopes and the favourable climatic conditions. The facility also recycles energy using heat pumps that can transfer heat into an available heat sink through district heating systems. At its peak, the system can deliver more than 20GW hours of heating energy to 9,000 Helsinki homes.

Ramboll’s expert services on this project included a LEED feasibility study, structural pre-design services, project management, site management, procurement of civil and MEP services, lead of user design, and supporting the client’s LEED and CEEDA certifications.
