HE HAS A LARGE FOOTPRINT

• 760,000 PCs• 215,000 servers• 147,000 networked printers• 512,000 Mwh of electricity• 275,000 tonnes of CO2

• Over £60 million in 2009- £1 million at Sheffield

• Reaches many students

WHY GREEN ICT? - ENERGY COSTS OF PCs

• High energy, high-usage PC with no power management could cost £61 per year in electricity (505 kWh/y @ 12p/kWh)

• Low energy, low-usage PC with power management could cost £3 per year (25 kWh/y @12p/kWh)

Whole life costing essential

QUEEN MARGARET UNIVERSITY

• Wanted greenest building in UK

• PCs main barrier

• 98% thin client

• 25-30% space savings

KEY LIFE CYCLE QUESTIONS• What balance of impacts across the life

cycle?

• Can we ever get a complete picture?- HP 1.5 million tonnes CO2 eq direct- 4.5 million tonnes from Tier 1 suppliers

• How can we influence upstream impacts?

LIFETIME IMPACTS• Energy (Carbon)

• Production:use energy - Williams/UN University 4:1- EU Commission study 1:4- SusteIT 1:1 as a working assumption

• Overall impacts are mainly use- energy; water; land take; chemicals;

PROCUREMENT• Quick Wins

- EU Energy Using Products Directive

• National Agreements

• Energy Star 5

• EPEAT

CARDIFF UNIVERSITY

• Low power servers

• Chilled water cooling

• Efficient layout

• Efficient UPS

• 30% support overhead

UNIVERSITY OF EDINBURGH

• High End Computing Terascale Resources- 60 Crays- 18-38 kW heat per rack

• 72% free cooling hours- £235,303 savings in 2008

• VSD - £128,650 savings pa

• Cooling overhead 16-31%

ICT BENEFITS – SMART 2020• Environmental

- Cut global CO2 emissions in 2020 by 15%, with $946 billion of cost savings- 5:1 es of CO2 emissions through applications for every tonne created by production, use & disposal of equipment

• Social- e.g. access; overcoming disability
