Data centres can consume up to 40 times more energy than conventional office buildings due to the high power needed to support IT equipment and cooling mechanisms.
Together with network equipment, they also account for almost 32% of the entire Information and Communication Technology sector's energy and carbon footprint, according to the Organisation for Economic Co-operation and Development.
To balance its customers' needs with environment conservation, Keppel Telecommunications & Transportation (Keppel T&T) takes a holistic approach in designing its data centres, and engages its stakeholders in implementing the best operating practices.
For its steadfast efforts to provide eco-friendly and energy-efficient services to clients, Keppel Datahub received a ‘green' stamp of approval from the Infocomm Development Authority of Singapore (IDA) and Spring Singapore on 31 March 2011.
Keppel T&T was among seven pioneering data centre operators to successfully achieve the new SS564 certification. The SS564 is a new industry standard that aims to provide a framework for data centres to achieve energy efficiency and continuous improvements.
On top of meeting the SS564 requirements, Keppel T&T looks into further details such as the design of chilled water pipes used in the cooling systems at Keppel Datahub.
By adopting an angular design for its pipes, which promotes better water flow, the overall efficiency of Keppel Datahub's cooling system has been significantly raised.
Such green efforts are also mirrored at Citadel 100, Keppel T&T's data centre in Dublin, Ireland. This data centre had recently collaborated with Dublin City University to jointly research and develop a technology to predict heat build-up and allocate cooling with high accuracy.
Since 2009, Citadel 100 had switched to use green electricity, which now accounts for 70% of its power consumption. This has reduced greenhouse gas emission by almost 30,000 tonnes per annum for the data centre, and is equivalent of taking 5,500 cars off the road.
