IBM & EnOcean: Self-powered Wireless Sensors
and Switches for Cognitive BuildingsHotel & Campus Projects

PROBLEM
Most hotel rooms and student rooms are unoccupied
over two-thirds of the time, but heating/cooling andother appliances are often still switched on, wastinga huge amount of energy.

IMPLICATION
Higher running costs and unnecessary environmental
pollution (CO2)SOLUTION
Existing rooms can be easily retrofitted using
maintenance free wireless sensors without affecting
the normal running of the building resulting in 30%
to 40% reduction in in-room energy usage.

EnOcean/IBM Gateway

SOLUTION IN DETAIL
Batteryless wireless occupancy sensor
adjusts temperature and turns off lights
when a room is not in use.

Batteryless wireless switches control
lighting and shading.

Batteryless wireless position sensors
setback HVAC when windows
are opened.

CO2 and humidity sensor measures
air quality.

Batteryless wireless key card switch
controls access to a room and turns onheating and lighting when entering a room.

Batteryless wireless room temperature
sensor for minimal energy consumption
and maximum comfort.

Ambient Assisted Living ProjectsPROBLEM
Global population is aging creating an imbalance
between elderly people and the amount of available(affordable) care.

IMPLICATION
Cost and availability of elderly health care and carehomes is now at prohibitive levels.

SOLUTION
It is essential to enable people to live as independently
as possible for as long as possible without invasive
monitoring (cameras). “Fit and forget” easily installed
maintenance free wireless sensors can provide raw
data to enable monitoring, profiling and as necessaryalerting relatives or carers.

SOLUTION IN DETAIL
Batteryless wireless occupancy sensor adjusts temperature and turns off lights when a room is not in use.
Batteryless wireless switches control lighting
and shading.
Attracting immediate attention in the case of an
emergency with call buttons.
Batteryless wireless position sensors setback
HVAC when windows are opened.

CO2 and humidity sensor measures air quality.
Pressure sensor detects weight changes andregisters a bed exit.
Batteryless wireless room temperature sensor forminimal energy consumption and maximum comfort.
Identify status of appliances (e.g. cooker) withCT clamps.
Identify status of electric, gas, water
meters with pulse counter.

Restroom Projects

PROBLEM
Optimal maintenance according to actual usage isvirtually impossible to predict.

SOLUTION IN DETAIL
Presence detection

IMPLICATION
Very often restrooms are not cleaned as required norpaper, soap etc. refilled, resulting in customer frustration.

SOLUTION
Restroom actual usage can be monitored using easily
retrofitted, maintenance free wireless sensors enabling
optimal cleaning and staffing, resulting in optimized
costs and customer satisfaction.

Flood detection
Door open/close detection
Paper empty sensor
Toilet fush sensor

Office Room Projects

PROBLEM
Floor space is at a premium (up to $50 per squaremeter). Many office spaces are utilized less than 70%(conference rooms, canteens, storage space, hot spacework areas etc.).

SOLUTION IN DETAIL
Presence detection
Thermionic people counter

IMPLICATIONThis creates unnecessary costs (floor area, heating,lighting, maintenance, running costs etc.) which runs into
$ millions p.a.

Water leak detection and area monitoringin residential homes.

PROBLEM
Late recognition of problems such as water leakage,heat damage or unwanted building intrusion.

SOLUTION IN DETAIL
Water leak detectors and shut off
valve in kitchen and bathroom

IMPLICATION
Costs the insurance companies billions every year, whichin itself is reflected on the ever increasing insurance
premiums paid by the customers.

SOLUTION
Easily installed, maintenance free wireless sensors
providing immediate data in case of flooding, fire and/or
unwanted intrusion which also alerts the customer andinsurance company.

Batteryless and wireless position sensors
monitor if windows are opened.

Smoke detector sets an alarm if smoke isdetected in the kitchen or living room.

Batteryless wireless room temperature
sensor for minimal energy consumption
and maximum comfort.

Batteryless wireless occupancy sensor
adjusts temperature and turns off lights
when a room is not in use.

Perimeter monitoring e.g. garden fence.

IBM & EnOcean: Self-powered Wireless Sensors
and Switches for Cognitive Buildings
With IBM joining the EnOcean Alliance as a promoter member in 2016, theorganization strengthened its program in building automation and the Internetof Things. For its Watson IoT ecosystem and cognitive buildings solutions,
IBM relies on the energy harvesting EnOcean technology in sub 1 GHz.
Together with IBM’s Watson IoT Platform, a fully managed, cloud-hosted
service, self-powered EnOcean-based sensors enable maintenance-freesolutions for Real Estate Management to increase operational, financial andenvironmental performance of facilities. EnOcean’s self-powered wirelesssensors are the eyes and ears of the IoT, as they collect the required datato operate large numbers of IoT devices efficiently, without any need of abattery.
In close collaboration, the EnOcean Alliance, EnOcean Alliance membersand IBM define and expand standards for self-powered solutions for the IoT.
These solutions can be used in various cases from asset management,
ambient assisted living projects, insurance or hotel and campus projects,
giving maintenance-free wireless switches and sensors based on EnOcean
technology.
