TRANSCRIPT
WORKSHOP
Topics include:
1. Powermeter use
2. USB controlled powerboards
3. WiFi energy monitoring
4. Low power motherboards/PC
5. Alternative energy sources - solar and wind
SUSTAINABILITY CHALLENGE
An average modern classroom is equipped with computers, large screen, lighting, heating and cooling and can be quite energy intensive – consuming 5-6 kilowatts of power
Average computer use consuming 150-200W
http://wiki.answers.com/Q/What_is_the_power_consumption_of_a_home_desktop_PC
The challenge is to have modern equipment and facilities to support good learning outcomes, and
Use technology in such a way as to minimise the energy consumed
The goal of the project is a modern classroom consuming only one kilowatt of power – this will require low energy desktop computing, less than 40watts per station.
PROCESS
Researching and learning the basics of ICT Sustainability
Experimenting - setting up a trial, purchasing hardware and software, and getting some hands-on experience
Doing a field trial to identify potential applications, gaining practical knowledge in real-world environments
Developing a feasibility study and proposal, choosing hardware and software vendors
Launching a pilot, to confirm technical operation, correct any problems and prepare for the final deployment and scaling
Presentation of results and review
LOW ENERGY DESKTOP COMPUTING PROJECTS
Thin clients
Atom processor mainboard
Solid state hard drives
Green power supply units
“Light” operating systems
Thin Client
Desktop with Atom Processor Mainboard
Solid State Drive
ACHIEVEMENTS
Thin client desktop:
30 watts under full load to
15 watts on idle
4 watts on off
Desktop with an Atom mainboard (Asus):
34 watts under full load
24 watts on idle
0 watts on off
ACHIEVEMENTS
A typical 2.5” hard drive based on rotating magnetic platters usually requires between -
0.5w and 1.3w when it runs idle
2 w and 4 w when it is under maximum load
Solid state hard drive
2 watts under full load
Less than 1 watt idle
ACHIEVEMENTS
Green Power Supply UnitsAn “80 Plus” power supply can save about 85 kilowatt-hours per PC, per year.
In many ways, it's the heart of a green PC, since it manages the power for all the other components.
It also has the most dramatic effect on your energy bill.
“80 Plus” power supplies are also lead-free and RoHS-compliant.
ACHIEVEMENTS
‘Light’ OS
“Light” operating systems
e.g. Zorin OS 4 lite
Nearly no risk of getting malware
Faster - its tested to be more than twice as fast as normal OS

FUTURE PROJECTS UNDER PLANNING AND DEVELOPMENT INCLUDE:
development of turn-key green ICT solutions
fitting out of a training room
development of multimedia resources in ICT sustainability
THE BENEFITSLearning for Sustainability
In embracing the ”one kilowatt classroom” concept we have been able to develop strategic skills and knowledge that place us well for future employment in this emerging Green IT area while adding considerable value to our community of knowledge
The low energy desktops demonstrate the theory and practice of Green IT to students – they will become an integral part of semester 2 delivery for the new sustainability unit :
ICTSUS4184A Install and test power saving hardware
