Virtus London2 (Hayes), London

London based data centre company VIRTUS called upon the mission critical expertise of NDY to design their LONDON2 data centre in Hayes, West London.

The brief from VIRTUS was clear: to provide a flexible, cost effective data centre space that was extremely energy efficient. VIRTUS had a clear objective to achieve a load density of up to 2kW per square metre at a very low PUE and using a Tier III topology to provide over 65,000 ft² of data hall space.

The use of indirect fresh air cooling supplemented by adiabatic cooling was key to underlining energy efficiency at Hayes. The subsequent lowering of the load-to-site energy ratio means VIRTUS will now have more power to use, or capacity to spare, adding to the flexibility of their offering.

Overall, our team was able to generate approximately 30% savings on energy expenditure, with features and innovations including the following:

• Indirect fresh air cooling supplemented by adiabatic cooling
• High efficiency self-scaling modular UPS systems
• Hot aisle containment and elevated server inlet temperatures
• Direct/indirect fresh air cooling of plantrooms
• Self-cooled high efficiency transformers
• Heat pump heating/cooling of office spaces
• Sophisticated optimised control and monitoring systems
• Photovoltaics to part offset energy consumption
• Integrated communication network
• Borehole water
• DCiM.
