Advanced Cooling Technology Can Cut Data Centers’ Energy Bills by One-Third

An advanced cooling technology able of reducing the cooling costs of large data centers by one-
third has been developed by researchers from Nanyang Technological University (NTU) and

The researchers are now “test-bedding a new data centre that combines Toshiba’s air cooling
technology with NTU’s advanced info-communications technology (ICT),” a news release stated.

Aiming to provide a sustainable solution for the data centers that operate in South-East Asia’s
tropical climate, the innovative test-bed is designed around a ‘cutting-edge modular structure’
(that is, container-sized modules that are able to stand alone or be combined with others for
more computing power) and with an efficient, tailored cooling system.

The cooling system uses the air outside of the data center for cooling whenever possible.
This cuts down greatly on the data center’s air conditioning needs. Outside air can be used
effectively whenever the outside temperature is lower than the overheated temperature inside
the data center, but most cooling systems instead use solely air conditioning, which is very

Data centers, which contain and maintain the “back-end information technology (IT) systems
and data stores consisting of mainframes, servers and databases,” usually use 100 to 200 times
more energy than conventional office buildings.

The technologies that were used in this test-bed have demonstrated energy savings of up to
40% when they are compared to conventional data centers used in Japan.
