Y.2064: Energy saving using smart
objects in home networks
• This Recommendation covers the following:
– General overview of energy saving using smart objects in
home networks;
– Requirements and capabilities for energy saving using
smart objects in home networks;
– Functional architecture for energy saving using smart
objects in home networks.
• Considers fixed home environment like residential
homes/buildings and mobile home environment like
networked electric vehicles (EVs) which support
ubiquitous networking among smart objects.

(fixed home environment)
• Energy saving system (ESS)
• Smart Meter /Home automation controller
• Home appliances/ storage/
• Communication equipment
• Surveillance cameras/ Personal devices
Smart objects in a vehicle
(mobile home environment)
• Passenger devices: smart phone, tablet computer.
• Vehicle dedicated devices for safety, maintenance,
power/fleet management, etc.
• Vehicle equipped devices: navigation, monitor, etc.
• Asset: moving products
5
Requirements for energy saving using
smart objects
• Home networks are required to
– support networking using various communication protocols and
interfaces
– deliver on-demand consumption and other information for
customers
– store most recent readings on energy consumption
– provide periodic energy monitoring information on request by
authorized market participant(s)
– support remote energy management (e.g., meter status,
activation/de-activation capability, error messaging, fraud
detection)
– support of remote changes of tariff through the interaction with
utility company

Energy saving through building
energy management
• Dynamic pricing and metering information transfer: To enhance
the efficiency of electrical power usage and provide detailed energy
usage in building, BEMS monitors and manages electric usage for
building operation and maintenance based on the input dynamic
pricing information and the provided usage information.
• Demand response message transfer: After receiving the message
to reduce demand by consumer with reaching to peak demand,
BEMS is able to control electricity usage in the building based on
BEMS energy management algorithm and policy.
• EV information transfer and EV’s electric charge and discharge:
Based on the information of EV’s state such as storage state,
operating schedule, BEMS is able to control EV’s electric charge and
discharge in order to optimize energy usage by EV.

Y.2070: Home energy management
system (HEMS)
• This Recommendation covers the followings.
– Overview of the HN service architecture for the HEMS and the other HN
services;
– Requirements for the device, the home gateway (HGW) and the management
platform (PF) in the HN service architecture as well as for the security required
for the architecture;
– Reference Architecture with four ways to connect to the devices from the
HGW according to the device types; the basic device (IP based and non-IP
based) and the non-basic device (connecting to the HGW directly and through
the adapter);
– Functional architecture with the entities; the device, the HGW, the
management PF and the application;
– Functional relationship with three functional categories in the functional
architecture; the device operation, the application execution and the
management;
– Security model and functions for the HN services with mainly describing the
HEMS.
