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

5
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

6
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)

7
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

8
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

9
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

10
Power usage monitoring

• Two options
• Power monitoring devices precise but expensive
• Power usage approximated by software doesnt
  cost anything, easy to install
• Software
• Takes into account mainly CPU
• Linear approximation
• Min and max power usage values specified for
  every computer

11
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

12
Current state and future work

• Current state
• Beta release available!
• Machine power state management works
• Test server is available for everyone
• Deployed in City Hall in Grodzisk Wlkp.
• Future work
• Live demo with video streaming for everyone
• Extensive large-scale testing (500 machines)
• More power management capabilities
• More advanced energy consumption analysis

13
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

Precise energy monitoring at home

• Precise monitoring of devices at home
• Using e-sockets
• Using smart meters
• Processing unit may be installed on the
  subscribers router
• Using GICOMP infrastructure
• Rich visualization of energy usage
• Feedback from user
• Better adjustment to tariffs

25
Precise energy monitoring at home

• Usage of subscribers lines
• Precise monitoring of devices at home
• Contact with the subscriber

26
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_at_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_at_Home fits well into our conception of
  home monitoring
