Improving workplace energy efficiency!
• Thin clients / desktop virtualization!– Thin clients are input / output devices only!– Computing power is centralized in servers!
• Disadvantages!– Not good for all applications!– Single point of failure (→ redundancy necessary)!– Requires a minimum number of workplaces!– Complex implementation!

Real world example: SBB!
• Action: !– Desktop computer replacement!
• Description:!– Replacement of 8500 desktop computers with 6000 notebook
computers and 2500 real-thin clients!– Thin clients use 85% less energy, 50% reduction in hardware
costs, no Windows license fees!– Tablets are provided to management to reduce paper usage!
• Energy saving:!– 3343 MWh / year = Energy usage of 671 households!– 183 t CO2 / year = CO2 emissions of 39 households!– Overall reduction of the energy consumption of the
19’000 workplaces by 25%!

Real world example: Swisscom!
• Actions: !– Use of UCC softphones instead of physical telephone sets!– Mobile phone recycling!
• Description:!– Phone calls are done with mobile phones or the Lync PC
conference system only!– Old mobile phones are collected. 20 - 30% can be reused in other
countries; profits go to charity.!
• Environmental impact:!– Removal of 15’000 phone sets and corresponding PBXs!– Reuse of 50’000 - 70’000 mobile phones each year which contain
up to 50 kg CO2 of grey energy and rare earth materials!
