- Obsolete computers in certain labs
- Energy consumption for current computer is higher than average
- Improper arrangement of wiring and computer placement causes waste of energy and heat build up
Problem solution
- Replace obsolete computers with more efficient ones
- Replace current computers with those that are up to date and based on performance per watt
- Do proper wiring and place computers accordingly so that heat output in the lab can dissipate effectively
Objective
- To reduce overall energy consumption for the university
- To promote green computing and propose a framework for all institute and companies to comply
- To promote Green Computing worldwide through this blog
Scope
- Low power, high efficiency hardware
- Virtualisation
- Efficient cabling and proper ventilation
Ethical issues
- Could pose certain problems to companies that are not ready to produce environmental friendly computer parts in terms of money and R&D
- Could cut jobs due to less maintenance needed
- Could cause shift in material trading which could either benefit or crash the market
Technique for improving performance per watt
- Virtualization
- Wiring length and wiring method
- Proper ventilation
Why these hardware are selected
- Cost effective
- Easy to replace
- 24/7 support
Budget
For lab:
- PC Low End = [(RM1599 * 25) * 4] = RM159900
- PC Medium End = [(RM2431 * 25) * 8] = RM486200
- Switches for Each Lab = RM120 * 12 = RM1440
- Cabling 1m = RM1.50 / 300 PC at 2m each = RM900
