Project: Khazna Data Centres

Description: Data Centre

Black & White won Electrical Project of the Year with Khazna Data Centres at the 2016 MEP Middle East Awards. Judges said the project was a clear winner and met almost all the elements they were looking for.

The Khazna Data Centre projects consisted of two (almost identical) double storey buildings; one located in Masdar (Abu Dhabi) and the other in Meydan (Dubai). Both data centres contained 2no. existing 1000m2 PODs (White spaces) from a possible 6no. PODs. B&W were employed to complete the MEP design for the POD 3 extension whilst maintaining the live data centre.

The electrical distribution provides ‘N+1’ distributed redundancy. The project required careful negotiations and hand-holding with the UAE local authorities to obtain approval for data centre type allowances which did not fully align with approval authority guidelines.

Khazna Data Centre incorporates a CHW system that utilises temperatures of 20°C / 28°C, these elevated temperatures maximise the efficiency of the chillers during mechanical cooling mode and allows for extended periods of free cooling. The free cooling and mix mode cooling systems are a significant factor in reducing energy consumption in tropical climates and is achieved via decoupling buffer vessels, closed circuit cooling towers and dedicated free cooling pumps.

Pipe-Flo is a hydraulic modelling software B&W uses extensively in the data centre design field, especially where resilient hydraulic looped networks are considered and normal / failures scenarios need to be explored. Along with IES, B&W are able to accurately model the building loads and system pressure drop, which provides a full understand of the hydraulics within the CHW system, which is invaluable during the commissioning stage.
