At the Consumer Electronics Association (CEA)® Technology &
Standards Forum in Seattle today, CEA announced that CEA-2047, CE-Energy
Usage Information, has been approved as a new CEA standard. This
standard enables consumer electronics devices to communicate how much
energy they use to consumers' computers, mobile devices running
smart-energy apps and third-party energy management services.
The Green Button Initiative - an industry-led effort that provides
consumers with easy access to their energy usage data - defines how
consumers can access a history of their home's energy usage from their
smart meters. However, the initiative does not tell them how much energy
a particular device or appliance uses, and getting that information
requires either an external metering device or the device itself to make
CEA-2047 recognizes that a manufacturer knows how much energy a device
will use during operation based on its design. This information can be
programmed into the device and used to calculate its energy usage over
time, without adding complex metering circuitry. An energy management
system or a smart-energy app can then gather the information over the
network and present it to consumers on their TVs, PCs, or mobile
devices. CEA-2047 is compatible with the Green Button initiative.
CEA-2047 also enables the Internet of Things to be energy-aware. The
standard can be used by devices operating on any home network including
Wi-Fi, Ethernet, ZigBee, Z-Wave, Bluetooth, and others. And because the
standard uses estimation rather than real-time measurement, it is
anticipated that almost any communicating device in the home will be
able to easily add this capability.
Bill Rose, chair of CEA's R7.8 working group that developed the standard
said, "With CEA-2047/CE-EUI, energy consumptio in the Internet of
Things can be broken down to individual devices such as appliances, pool
pumps and heaters, air conditioning systems, and other devices so
consumers can see exactly where, how much, and when electricity is being
used. The standard will also enable consumer-authorized, third-party
developers and services to grow by providing them the information they
need to help consumers save on their energy bills."
Publication of CEA-2047 parallels other initiatives within the industry
to reduce and monitor energy consumption. Other CEA standards in this
area include CEA-2037-A, Determination of Television Set Power
Consumption and ANSI/CEA-2043, Set-top Box (STB) Power Measurement.
CEA cooperated with the Smart Grid Interoperability Panel (SGIP) on the
development of CEA-2047. The standard will now be submitted to ANSI to
become an American National Standard.
