Energy harvesting: ambient light

03.08.2010 © Thermokon 2008 Page 20 of 15

• Ambient light > 50 lux powers sensor

• 3h charging at 200 lux provides enough energy for 14h in total darkness

• Fully charged devices survive more than 3 days in total darkness

• No overhead, 14 byte only

• High speed transmission (« 1ms)

• Randomly timed multiple transmissions

Temperature cyclic

Setpoint cyclic

Occupancy button adhoc

Fan stage setting cyclic

Cyclic:

if value has changed since last

transmission, cycle time is 100s.

If unchanged, cycle time is ~ 16 min.

Physics – signal damping

03.08.2010 © Thermokon 2008 Page 25 of 15

• Signal damping when

propagating though

walls

• Damping depends on

material and water

content

• Furnitures damp as

well !

Radio range in building:

20-30m typ.

55 floors

more than 100 tenants

13000 lights and blinds

4200 switches

„Battery based radio systems are

cheaper“

„Battery life is up to 7 years according

to datasheet !“

Question:

Which switch will determine the

replacement interval ?

Initial situation

• 27 guest rooms in each building (2 stories)

• No individual temperature control in the guest rooms

• Floor heating

• No automation: manual manifolds

• Hot rooms in winter

• Temperature controlled by clocked boiler modulating the flow temperature

• High average annual consumption:

150 kWh/m²

Page 41: Thermokon & Easy Sens

Concept for first building

• LON network

• Each room to be equiped with:

– LON Room thermostat

• Outdoor temperature sensor to

control flow temperature

• Integrate existing central heating

boiler

• Add electrothermal valves to floor

heating manifold

EasySens Window contacts

• Connect room automation to

booking management system

• Thermal metering
