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)
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
Task: OS Power Management capabilities • Be cross platform... • Windows • Linux • Mac OS X • PM capabilties • ACPI states – suspend, hibernate, turn off • More options – dim/turn off display, turn off hard disk, manage wireless adapter settings • Wake-on-LAN • Export functionality and information over a network
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 • Twooptions: • Power monitoring devices – precise… but expensive • Power usageapproximated by software – doesn’tcostanything, easy to install • Software: • Takesintoaccountmainly CPU • Linearapproximation • Min and max powerusagevaluesspecified for everycomputer
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
Current state and future work Currentstate: • Beta releaseavailable! • Machine powerstate management works • Test serverisavailable for everyone • Deployed in City Hall in Grodzisk Wlkp. Futurework: • Live demo with video streaming for everyone • Extensivelarge-scaletesting (~500 machines) • Morepower management capabilities • Moreadvancedenergyconsumptionanalysis
Deployment in City Hall • GICOMP deployed in City Hall in Grodzisk Wlkp. • Constantly monitoring power usage of 20 computers • 5 different „generations” of machines • Power policies applied on every computer • Access through web browser

Wireless measurement system • Project: PSNC • Measurements • Instantaneouspower • Maximum power • Functionality: • lightdimmer • switch • Support for devices up to 900W • Communication: • ZigBee • Large-scaleproduction: • 80 PLN
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
Precise energy monitoring at home • Usage of subscriber’slines • Precise monitoring of devices athome • Contact with the subscriber
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
