Throughput of external air avoids the need for mechanical cooling
“This use of direct air from outside in cooling is unusual,” says Martien Arts, Mission Critical Facilities, Royal HaskoningDHV. “We designed a unique structure to facilitate it. The building is angled to face the dominant wind direction. The design, which looks like an aeroplane wing, creates differential air pressures at each end to draw the wind through the building. We designed and tested the shape, as well as the impact of wind, pollution, rain and snow.”
A heat exchange system in the data centre connects into the district heating for a nearby village in the southern province of Mäntsälä. The building has an extremely low energy consumption and PUE just above 1.0. We ensured it is fit for purpose, customised for Yandex’s equipment and operations, by challenging the design criteria. The process led to construction costs being significantly reduced to nearly half typical data centre builds.Next generation data centre design
Based on the success of the Finnish data centre, Yandex asked us to develop a design which could be adapted across Russia, for multiple climate and seismic zones. It needed to offer the capability of operating in extreme heat or cold and to withstand seismic disturbance or heavy snow.
Our modular blueprint was made up of three sections - the data centre, cooling and electrical part. Each can be modified depending on local conditions. Automated design methods enable changes to be made to the parameters quickly and easily. The first centre built using this design approach is in Vladimir in western Russia. Future expansions across Russia are in preparation.
