9. A greener society with ZigBee
ZigBee helps better manage energy and supports
the Smart Grid through the Smart Energy profile
ZigBee is used in over 40 million smart meters
currently in deployment around the planet
Large scale deployment of ZigBee sensors will help
achieve the Sustainable Homes and Buildings
objective
However, most wireless sensors are still faced with
a critical issue: batteries
Enabling the use of energy harvesting technologies,
ZigBee Green Power is a key contribution to a world
with less batteries

11. The rationale for demand response
Some facts
– Local use of electricity is rising between 1 and 11% per year
– Producing electricity creates 37% of all greenhouse gases
– Coal is still the fastest growing fuel for making electricity
– There is no effective large scale storage technology
In many situations demand management is the only
remaining choice to ensure energy sustainability

12. What is ZigBee Smart Energy?
Smart Energy is ZigBee’s open standard way of
achieving
– Demand response and load control
– Energy management and metering services
– Presentation of grid status and energy costs
– Utility customer communication
– Many more features enabling the Smart Grid
ZigBee Smart Energy is achieving
worldwide presence
– Proposed to IEC as basis for a smart metering standard
– Endorsed as key standard by US DoE and NIST
– Endorsed by ESMIG for smart metering across Europe

15. A world with less batteries
Energy consumption and battery
operation are two of the most
critical challenges for wireless
sensor networking
Combining energy harvesting and
wireless communications allows
for maintenance free control and
monitoring
There are huge market
opportunities for batteryless,
wireless solutions, in particular in
the building/office/hotel segments

16. What is ZigBee Green Power?
Green Power is ZigBee’s open standard way of
enabling batteryless or ultra low power applications
– Light and shade switches, remote controls
– Measurement sensors, thermostats, closure detectors
– Panic and emergency buttons
– Gas and water meters
– Industrial switches
ZigBee Green Power delivers end to end compatibility
with existing (battery or mains powered) devices

17. What ZigBee Green Power delivers
No maintenance
No battery waste
Increasing pressures and incentives for energy
savings, wherever they come from
Can lead to easier, faster installation
Can allow for different form factors, more compact
devices
Reduced fire risk in some industrial environments

18. Example: Self Powered Switch
TRANSMITTER RECEIVER SOLUTION
Self powered Switch
e.g. Wall Switch
+ ZigBee Proxy
e.g. Socket Outlet = Reliable Control Anywhere
e.g. Lighting, Shade

19. Conclusions
In a world where energy is becoming a scarce
resource, all means to optimize its usage must be
deployed
ZigBee is today the key wireless sensing and
control technology to drive energy efficiency in
homes, buildings and power hungry environments
ZigBee Smart Energy and Green Power will help
achieve the Smart Grid and Sustainable Homes and
Buildings visions
