Problems
• 31% of computers are not turned off after working hours (PC Energy Report, UK NEF)
• There are a lot of breaks during office work
• Idle computer utilizes 90-120W
• LCD monitor takes 20-30W
• Energy prices constantly rise
• Machines must be sometimes turned on after working hours: backup, update

Ways to save energy
• Turning off monitors during short breaks at work (e.g. 1-5 min)
• Suspending machines to RAM during longer breaks (e.g. more than 5 min)
• Turning off machines after working hours
• Turning on machines according to specified schedule:
• User preferences
• Updates and backups

Estimation of savings
Assumptions:•105W PC•25W Monitor LCD•30% not turned off at night•10% not turned off during weekends•2 long breaks during day•5 short breaks during day•per year

GICOMP
• Save energy in environments with large number of computers
• Easily manage multiple machines from one place
• Create power policies for groups of computers
• Monitor and control energy usage (also control at outlet level)
• Analyze historical energy consumption (up to one year back)
![Page 7: GICOMP Green IT Control and Measurement Platform](https://reader037.vdocuments.us/reader037/viewer/2022103100/568131fb550346895d985761/html5/thumbnails/7.jpg)
GICOMP
•Easily manage large groups of computers
•Specify same power policies for multiple computers
•Programs on the nodes can be installed with a few clicks
![Page 8: GICOMP Green IT Control and Measurement Platform](https://reader037.vdocuments.us/reader037/viewer/2022103100/568131fb550346895d985761/html5/thumbnails/8.jpg)
Task: OS Power Management capabilities

GICOMP Architecture
Roles:•GUI – user-friendy flash interface
•Manager – accepts requests from GUI, saves data in database
•Service – controls nodes, sends requests
•Node – OS-level info and functionality
•Waker - brings up a group of Nodes

Power usage monitoring
• Two options:• Power monitoring devices – precise… but
expensive
• Power usage approximated by software – doesn’t cost anything, easy to install
• Software:• Takes into account mainly CPU
• Linear approximation
• Min and max power usage values specified for every computer
![Page 11: GICOMP Green IT Control and Measurement Platform](https://reader037.vdocuments.us/reader037/viewer/2022103100/568131fb550346895d985761/html5/thumbnails/11.jpg)
Historical power usage
• Data saved in RRD database – round-robin database
• Historical data available up to one year back
• Possible to retrieve power usage statistics for selected computer, as well as for a group of machines

Precise energy monitoring at home
• Precise monitoring of devices at home:
• Using e-sockets
• Using smart meters
• Processing unit may be installed on the subscriber’s router:
• Using GICOMP infrastructure
• Rich visualization of energy usage:
• Feedback from user
• Better adjustment to tariffs
![Page 25: GICOMP Green IT Control and Measurement Platform](https://reader037.vdocuments.us/reader037/viewer/2022103100/568131fb550346895d985761/html5/thumbnails/25.jpg)

Precise energy monitoring at home
• Vendor could supply with e-sockets and software installed on routers in exchange for collecting data about energy usage
• Profits for client• Energy usage visualization
• Automatic shutdown of devices according to schedules or remote control of devices
• Reduced energy costs by better adjutment to tariffs
• Profits for vendor:• Reduced peak network load by proposing clients individual
tariffs and promoting other hours of energy use
• Marketing information that may be sold, e.g.: users in this area have old TV sets
• Feedback from user – contact with the consultant online

Our conception of smart homes
• Smart homes solutions are currently very expensive and not popular
• Google Android@Home• Royalty-free specification for smart homes
• Integration with Android phones
• Open environments for building automation: Arduino
• What does it change?• Royalty-free very welcome in China
• Easy access for users: consumer devices
• First devices: Google Lightbulb (Lighting Science)
• Android@Home fits well into our conception of home monitoring
