BENEFITTING FROM GREEN IT – FINDINGS FROM THE SUSTEIT PROJECT Professor Peter James

THE CASE FOR CHANGE Sticks - Energy and other costs - Regulations Carrots - financial and operational benefits - teaching and research Reputation Stakeholder requirements

ICT BENEFITS – SMART 2020 Environmental - Cut global CO2 emissions in 2020 by 15%, with $946 billion of cost savings - Avoid c 5 tonnes of CO2 emissions through applications for every tonne created by production, use & disposal of equipment Social - e.g. access; overcoming disability

KEY LIFE CYCLE QUESTIONS Can we ever get a complete picture? - HP 1.5 million tonnes CO2 eq direct million tonnes from Tier 1 suppliers What balance of impacts across the life cycle? e.g. production:use energy - Williams/UN University 4:1 - EU Commission study 1:4 How can we influence upstream impacts?

CARDIFF UNIVERSITY Low power servers Chilled water cooling Efficient layout Efficient UPS 30% support overhead

ACTION PLAN - MANAGEMENT Calculate energy consumption - formulate action plan and targets Set up a cross-functional team Calculate total cost of ownership - energy prices; refresh cycles; support costs Energy-related financial incentives for IT - paying energy bills for server rooms?

ACTION PLAN - DESKTOP Power down computers when not in use - network software; PC settings Ensure all non-managed computers are powered down when not in use Make 5 year refresh cycles the norm - justify exceptions by evidence and sign off Specify Energy Star 4 (soon 5) for all purchases Dispose of old equipment responsibly

ACTION PLAN - PRINTING Audit paper consumption - set targets - measure/monitor consumption Power down printers outside office hours Encourage paper-efficient printing - draft mode - double sided

ACTION PLAN - INFRASTRUCTURE Follow the EU Code of Conduct for all significant data centre investment Take simple measures to minimise cold/air mixing in server rooms - e.g. containment; blanking plates Consolidate servers - switch off unused ones

MEDIUM TERM MEASURES Metering/monitoring key areas of consumption Full implementation of EU Code of Conduct - power supply; virtualisation; free cooling Maximum use of thin client where effective Effective document and print management Minimising storage Increasing videoconferencing Flexible working

QUEEN MARGARET UNIVERSITY Wanted greenest building in UK PCs main barrier 98% thin client 25-30% space savings

THE FUTURE Less energy and material intensive desktops - cloud computing - medium client - e-readers and ‘total content’ Zero carbon data centres Pay as you go computing Intelligent campus - from computer to building maintenance?
