Guest Speech – Che-Hoo Cheng

Green computing: a central IT service perspective

in Theme 3: Sustainable Technologies

Green is the global trend for environmental protection and sustainability. The Chinese University of Hong Kong (CUHK) is committed to campus sustainability under the coordination of Campus Planning and Sustainability Office (CPSO) with the support of Campus Development Office (CDO), Estate Management Office (EMO), Information Technology Services Centre (ITSC) and other departments. As central IT department of CUHK running two medium-size data centres serving the whole university, ITSC is obligated to improve energy efficiency with economy of scale for data centre operations. Building small data centres or server rooms by individual departments are not encouraged because energy efficiency of running them is usually low. Various measures are in place for that. Besides running efficient data centre operations, Information Technology (IT) can also help conserve energy in many other ways. It can be called Green Computing in general. The speaker will try to cover the topic of Green Computing from central IT service perspective.
