Energy Saving on Campus PC's

Goal

To reduce carbon emissions generated by the University's ICT infrastructure, by the devices attached to it, and by changing the ways in which these devices are used. 


Students' Personal Computers

Power Management: All students should power-down their computers and peripherals when not needed for use.

Power management: Recommend the use of power devices that turn off peripherals when PC is powered off.


Public Access Labs and Teaching Space PCs

Power Management: Public access PCs that are not in use will normally be powered down at at 10.00pm each day. Outside of normal office hours, public access PCs will normally be powered down after 60 minutes of inactivity when not logged on.

Power management: Public access PCs will normally be powered up 30 minutes before the start of each working day.

Service management: ISS will roll-out systems management software that will power up PCs overnight, apply patches and updates and power down.


Staff Computers (for Administration)

Power management: All users are recommended to power down their PCs and monitors at the end of the working day. There is no longer an ISS requirement to leave PCs running overnight for application of software updates. Staff can power down their PCs and monitors at the end of the working day to reduce energy consumption.

Power management: Recommend the use of power supplies that turn off peripherals when PC is powered off.

Procurement: Staff will normally buy desktop systems that have certified low power consumption, and will normally buy from a centrally recommended source for which university or sector purchasing frameworks have been negotiated.

Service management: ISS will roll-out systems management software that will power up PCs overnight, apply patches and updates and power down. This may offer opportunity for PCs to be powered up 30 minutes before planned arrival at work.


Staff Computers (for research)

Procurement: Staff will normally buy desktop systems that have certified low power consumption, and will normally buy from a centrally recommended source for which university or sector purchasing frameworks have been negotiated.

Procurement: Server purchases for research will balance performance and power consumption; following the same guidelines as for ISS data-centre hardware (outlined below).


Point of Sale computers

No specific recommendations.


ISS Managed Servers

Procurement: Procurement for server software will give preference to systems that we can deploy in our virtual environment.

Data-centre hardware procurement will give preference to suppliers who:

Who can supply products that consume less power for a given level of performance

Present figures on the embodied carbon in their products

Whose products contain less embodied carbon (when comparison is possible)

Provide modular upgradeable hardware, and extended warranties that can extend the effective life of the supplied product


Servers not managed by ISS

Virtualisation: of server hardware has been proven to offer significant carbon and energy savings, in addition to a range of other important benefits. ISS now offers a high quality virtualisation service available to all, which is ideally suited to servers previously managed independently in departments and faculties. Virtualisation of the computer hardware need not change server administration rights and responsibilities. ISS is also able to assist in the decommissioning and disposal of the old physical hardware.


Machine Rooms

Energy Efficiency: Only computer rooms that have energy efficient cooling systems (e.g. utilising 'free cooling' technologies) will be used at the University beyond July 2011. As an university, we will set an annual target of less than 25% computer power consumption overhead for cooling (where normal is between 30 and 50%).ISS will make space available in energy efficient machine rooms in order to retire inefficient machine rooms by migration of services (particularly, migration of services to virtual hardware).


Process Improvements

Printing efficiency: The university will adopt as a default duplex printing, and the use of recycled paper in all but exceptional circumstances.

Printing power reduction: As part of university procurement practices, we will normally select printers that have low power consumption.

Reduce Reliance on Printing: As part of ongoing university process reviews, we will seek to remove printed paper requirements from university processes wherever feasible.


Recycling

WEEE: The university will follow the Waste Electrical and Electronic Equipment (WEEE) guidelines as set out by the government.

Consumables: as well as providing recycled paper for printing, the university will ensure that consumables (such as printer cartridges) are recycled.
