white paper – The Ecosystem of the EnOcean Alliance

What is the EnOcean Alliance?
The EnOcean Alliance was initiated in 2008 by leading companies from the building sector. It
is an open, non-profit organization, which aims to make buildings more energy-efficient, moreflexible, and more cost effective by using intelligent wireless automation solutions. The
Alliance’s core technology is the EnOcean energy harvesting wireless standard. Currently,
nearly 400 members belong to the EnOcean Alliance, which offer more than 1,500
interoperable products (status July 2015). The Alliance is headquartered in San Ramon,California.
The Alliance’s major objectives include:establish energy harvesting wireless technology as the wireless standard for sustainablebuildings

help further the use of wireless monitoring and controlling products in buildings andfurther internationalize the technology

continuously improve the specifications for the interoperability of EnOcean-based
products

What are the Alliance’s main tasks?
A major task of the EnOcean Alliance is to establish energy harvesting wireless technology
as the leading wireless standard for sustainable buildings and to enable interoperable
wireless monitoring and controlling
products in and around residential,commercial and industrial buildings.
For this, the Alliance ensures theinteroperability of EnOcean-based
devices and solutions by defining
standardized
application
profiles(EnOcean Equipment Profiles, EEPs)
based on the international wirelessstandard ISO/IEC 14543-3-1X. This
enables products from different
Alliance members to seamlessly work
together in a system.
In addition, the organization offers its
members a platform of vital exchange and partnership. Today, the EnOcean Alliance is oneof the fastest growing technological alliances and has the largest installation base of ultra-low
power wireless devices in commercial buildings worldwide.

What is the EnOcean Standard?
The EnOcean standard is based on the international wireless standard
ISO/IEC 14543-3-1X, which is optimized for ultra-low power wireless applications and energy
harvesting. The standard can be downloaded at www.iso.org. The EnOcean radio protocol is
specifically designed to support devices, which are powered by the energy of their

page 2/9white paper – The Ecosystem of the EnOcean Alliancesurrounding environment. This energy harvesting principle enables wireless applications towork without wires and batteries.
Products that use the energy harvesting wireless standard are normally labeled with the
EnOcean Alliance Ingredient Logo:

The EnOcean technology’s three major energy sources are motion (harvested by electromechanical converter), light (harvested by miniaturized solar cells) and temperature
differences (harvested by thermo generator and DC/DC converter). EnOcean GmbH, thefounding company of the basic technology and a Promoter of the EnOcean Alliance, markets
its comprehensive energy harvesting platform of energy converters, wireless modules,
energy management, and ultra-low power radio to OEM customers worldwide.

What are the specifics of the EnOcean Standard?
The EnOcean standard is ideally suited for reliable wireless communication in building andhome automation. For optimal RF effectiveness, the radio protocol uses sub 1 GHz
frequency bands, which offer high penetration through walls, furniture and other barriers in abuilding. At the same time, the electromagnetic fields emitted by the wireless devices areextremely low, which minimizes electric smog. RF reliability is assured because wirelesssignals are less than one millisecond in duration and are transmitted at a data rate of
125 kilobits per second. The short telegram is randomly repeated twice in the space of about
40 milliseconds to prevent transmission errors. The range is up to 100 feet/30 meters inbuildings and 1,000 feet/300 meters in the free field.
The EnOcean standard optimally uses different frequency bands in different countries,including 868 MHz in Europe, Africa, South America, Middle East and China; 902 MHz inNorth America) and 928 MHz in Japan; and 315 MHz in Asia and other countries. This allows
for the technology to be suitable for worldwide use.

white paper – The Ecosystem of the EnOcean AllianceWhy do buildings need the EnOcean standard?
Governments around the world have set ambitious goals to significantly reduce energy
consumption over the next couple of years. Buildings play a key role as they consume 40 %of the primary energy. Existing buildings take the highest share, which demands theintegration of innovative technologies that can be installed easily, especially retrofit projects,
with a fast return on investment (ROI) whilst providing significant energy savings.
Energy harvesting wireless devices are the ideal solution to meet this demand. They bridge
the last leg to provide all the data needed for intelligent central control in commercial
buildings and smart homes. With no wires to pull, and no need for access to replacebatteries, it yields devices that are highly flexible and easy to position, remove, and relocate.
It eliminates the cost and effort associated with installing wiring and conduits, and it enables
maintenance-free and long lifespan systems, resulting in the most cost effective wirelessbuilding control systems.
Employing energy harvesting wireless solutions, installers and system integrators can utilize
the energy saving potential of a building quicker and with less effort. In addition, the freely
placed components fit into flexible office and living concepts, in which partitions and room
divisions should fit into the heterogeneous requirements of different users. In the case of achange in the room structure, the switches and sensors relocate easily.

What does a battery-less wireless automation system look like?
An automated building or smart home using battery-less wireless components can berealized flexibly with different system architectures according to individual requirements.
When choosing a system, in particular for retrofit projects, it is important to consider the onsite conditions as well as the goals of automation.
The following illustrative graphics show an installation example in a commercial building anda smart home:white paper | EnOcean Alliance | July 2015

What saving rates can be achieved?
Based on battery-less wireless technology, intelligent HVAC system and sophisticatedlighting control can be realized using self-powered automated thermostats, window contacts,
key cards, humidity sensors, occupancy and light level sensors, switches and CO2 sensors.
These are just a few examples of the self-powered products in place, to regulate climate andlighting control automatically. As battery-less devices use standardized communication andapplication profiles, system integrators can flexibly combine solutions from different vendors.

Monitoring and control capabilities, such as temperature sensors, occupancy detection, orlight level and window status sensing, require low data rate transmission via sensors andswitches that are highly flexible to install. This level will be dominated by the EnOcean
energy harvesting wireless standard, which enables small devices to be powered by theirsurrounding environment. The technology has already been already proven with successful
deployment in several hundred thousand buildings worldwide. With potentially more than ahundred of such devices in a smart home and several thousands of them in commercial
buildings, it becomes immediately apparent that battery- or wire-powered devices are not anoption for this communication level. The highly flexible and sustainable EnOcean energy
harvesting wireless standard is the perfect fit to provide the needed data from thousands ofmeasurement points to a supervising system.
However, a building also needs high data rates. This can be video streaming, security
cameras, or data processing in the cloud via WiFi and TCP/IP, for example. In the future, allof these communication levels will work together seamlessly. With the boundaries between
products, standards, and disciplines dissolving into one solution, the user doesn’t need torealize the crossover of different standards anymore; instead, the user beneficiallyexperiences only the underlying results of increased energy efficiency, comfort, and security.
