Scope Purpose

• Scope
• Architecture of Energy Saving System (ESS)
• Conceptual model of ESS
• Basic architecture of ESS
• Requirements
• ESS client
• ESS server
• ESS server-compatible home appliance
• Purpose
• In order to provide consumers
• With energy monitoring functions to make them
  aware how much electric energy they are consuming
• And with Intelligent energy saving functions to
  cut off passive and active standby power that
  consumers are not aware of

Energy Saving System (ESS)

• Functions of ESS model 2
• (1) Functions of ESS model 1
• (2) Detection of active standby power mode of
  appliances
• (3) Saving and restoration of context
  (network configurations, etc.) of appliances
• (4) Cut-off of active standby power of home
  network devices
• (except home gateway, home server, home
  security, etc.)
• (5) Monitoring of energy consumption status
  (optional function)

ESS model 2 (2)

• Functions of ESS model 2 Functions of ESS model
  1 additional functions
• Addition functions of ESS model 2
• Detection of active standby power mode of
  appliances
• Cut-off of active standby power
• Monitoring of energy consumption status (optional
  function)
• Feasible types
• a stand-alone system
• functional modules that can be implemented into
  legacy home gateway (or home server)
• Requirements related to
• Functions of appliances, ESS clients and ESS
  server
• Saving of context of an appliance before cutting
  off its supply of electric power
• Restoration of context of an appliance after
  supplying electric power
• Simple communication protocol for
  power-monitoring and power-control between
• ESS clients and server

Functions and Classification (1)

• Appliance
• Supporting devices
• Legacy home appliances and legacy home network
  devices
• ESS clients cut off only passive standby power of
  legacy devices.
• New home network devices which meet this
  specification
• ESS server and clients cut off both of passive
  and active standby power.
• ESS Clients
• Functions
• Function 1 Cut off the supply of electric power
  by itself or an ESS server
• Function 2 Detect passive standby power mode of
  appliances connected to it
• Function 3 Detect active standby power mode of
  appliances connected to it
• Function 4 Calculate (or measure) the amount of
  consumed power (or electric current
• and voltage) and send result to ESS
  server
• Classes
• Class 1 ESS clients which meet Function 1 and 2
  above (for ESS model 1)
• Class 2 ESS clients which meet Function 1, 2
  and 3 above (for ESS model 2)
• Class 3 ESS clients which meet Function 1, 2, 3
  and 4 above (for ESS model 2)
• Feasible Types

9
Functions and Classification (2)

• 3) ESS server
• Functions
• Communication Function
• Be notified the active standby power mode of
  appliances
• Send control commands to ESS clients in order to
  cut off the supply of electric power
• Send query commands to ESS clients in order to
  monitor the power consumption status of
  appliances
• Monitoring function
• Build DB by using data from ESS clients
• Query functions (with device name or ESS client
  ID)
• Display total amount of power consumed during a
  specific period
• Energy saving function
• Cut off active standby power consumed by home
  network devices
• User-configurable interface and alarm service
• Feasible Types
• Type 1 stand-alone type (no connection to home
  server or home gateway)
• Type 2 stand-alone type, but it is
  interoperable with home server or home
• gateway
