3. Features of PAWS? Server Controlled End user has the power! Savings stats are auto generated
4. Environmental Impact? 1 computer will typically consume 2.5 KW/h units of electricity per day So 750 computers will consume a total of 685,000 KW/h units a year! The PAWS prototype at Aber is currently saving an average of 28 tonnes per month of CO2 on public computers That’s approximately £100,000 a year electricity saving! PAWS will potentially carry this to an extra 1100 Staff computers and double the savings.
5. Goals? Open Source Institutional benefits View our blog at http://paws.aber.ac.uk Build on Previous Green ICT Projects Contact: Rob Johnson, rob.johnson@aber.ac.uk Help meet CO2 reduction aspirations
Editor's Notes
Introduction - Who am i….where I am from PAWS = Power Down & Wake System What is it? An desktop power management solution offering automated sleep and waking capabilities, we have developed a prototype now live at Aberystwyth University in public workstation rooms and will now develop for the staff computer environment handling different working patterns. How long? 9 months, ending December 2011 External institutions involved - Swansea University & Trinity St Davids in Wales will participate in testing generic aspects of PAWS
Why? Commercial products such as 1e’s Nightwatchman that is the UK Public Sector’s preferred product: we found too expensive, costs £20K to make £50K savings Free products: too inflexible for our institution’s requirements and did not offer sufficient savings reporting that would be invaluable information for both the estates departments and individual users. Customise: allows us to develop the features that would best suit the characteristics of our organisation, e.g. such as staff computers being configurable by user yet public workstations be configured by room.
How? Server controlled sleep management of client computers – more accurate control and logging capability End user has the power: PAWS provides a user interface by which the end user clients may manage their own power management profile, and may also wake their computer up remotely should they wish to remote into their computer Power statistics and savings pages are automatically published to the web and the information may also be delivered as PDF reports
Environmental Impact? -
Goals? Build on findings from previous JISC funded Green ICT projects to build this sustainable product Open Source: The project deliverables will be delivered by an open source licence and made available to the community, allowing the product to potentially be enhanced further Institutional benefits: a cost effective way of building on this concept to deliver the solution at institutions across the sector. Should commercial products be in use, hopefully PAWS will carry the potential to supercede these and thus reduce institutions costs. Government target: 40% reduction on 1990 CO2 levels, PAWS will hopefully significant contribute towards this reduction
