The project focused on the first phase of a data centre campus, comprising four separate buildings, which when fully built-out would support a total of 15.3MW of critical load. Each building contains two 978 m2 data halls, each supporting 1.9MW across 494 racks.

Cooling to the data halls is achieved using ‘Excool’ indirect air-cooling units that work through a combination of mechanical ventilation and adiabatic cooling to deliver the coolth to the data hall.

The climate in Dublin is ideally suited to the use of indirect air cooling. The use of this strategy, together with other energy efficiency measures, achieved a total annualised PUE of 1.15 and a Total WUE of 0.7. The data centre campus achieved BREEAM Excellent rating, and UTI Certified Tier III. Total CUE was 0.0625.

The project was one of the first to utilise Indirect Air Cooling, and the first ever of this type to be constructed in Ireland and to achieve UTI Tier III certification. This required lengthy engagement with the UTI Assessors, who were not familiar with the technology. The process was an interesting and rewarding one for all concerned.
