BCS Data Centre Specialist Group
The University of Leeds World-class, multi-discipline, research-
intensive university £500m pa turnover 32,000 students 8,000 staff Countless regional, national and
international collaborators and information users
IT at the University £35m pa on IT – 7% of turnover 12,000+ university computer clients 500+ servers 10,000? student personal computers on
campus and in residences High Performance Computers (HPC) Two enterprise data centres (third being
developed), seven medium data centres, numerous informal servers
IT and air conditioning two greatest energy growth areas at the University
Sustainable development at Leeds Cost reduction, legislation, institutional
desire and individual goodwill University strategic objective
Deputy Vice-Chancellor led Sustainable Development Manager
Six strands: Estates Finance & Procurement Academic & Educational Alignment Citizens IT (“SusIT”)
IT sustainability areas Purchase/disposal carbon impact
Materials, production, packaging, transport, disposal
Recurrent carbon impact Energy consumption and usage efficiency
Capital cost Purchasing and tender requirements
Recurrent operating costs Licences, maintenance, support, etc.
Reducing the carbon footprint of IT and using IT to reduce our carbon footprint Leadership and education Stop it getting worse:
Procurement policy Manage what we currently have:
Measurement The largest energy consumers: data centres The largest number of energy consumers:
clients (12,000+) and printers (30m pages pa) Make it better in future
Data centre design and IT architecture Server-based computing Remote and mobile working
First successes IT procurement policy changed
Institutional PC procurement Whole life-costing of new HPC
Blank (with passwords) screen savers Automated power down of monitors and
clients 4,300 PC trial: 0.7GWh and £73k pa saved
Server virtualisation Printers and print management
Students first: pull, multi-functional devices, £90k pa expected savings
Thank YouColin Coghill

The size of the issue 2% of global C02 emissions down to IT –
equivalent to the airline industry (Gartner) IT predicted to triple its emissions between 2002
and 2020 (The Climate Group) An enterprise class data centre uses more power
in one year than the city of Leicester (Broad Group Research)
Energy costs predicted to rise from typically less than 10% of the IT budget to more than 50% in the next few years (Gartner)
Two-thirds of office energy consumption is down to IT (The Carbon Trust)
