All modules communicate with each

other in the Plugwise network.

Additionally, each module functions

as a router.

A switching command to a certain

plug is automatically transmitted

via the most efficient route

(circumventing obstructions).

…the system will automatically

choose the second most efficient

route.

If for any reason the route is blocked…

ZigBee technologyZigBee is a reliable, robust, self healing RF-

technology for monitoring and control :

• Open international standard (adopted by many utilities)

• Full dynamic ‘MESH’ network support

• Plugwise’s profile has highly secure authentication via 128-bit AES encryption

• Based on Zigbee Pro with a manufacturing specific profile but accessible (with key) to other non Plugwise-systems

• Highly resistant to interference from other wireless systems

• Upgradable over-the-air (OTA)

• Easily extended with additional plugs or multiple networks

• Plugwise’s system is uniquely developed to support very large professional networks (1000’s)

• Every device has its own unique MAC-address (and each device can be individually and uniquely identified with its location)

Be wise, plug in.

Certifications

• Compliance with European R&TTE directive confirmed by TüVRheinland

• Safety and electro-magnetic compatibility (EMC) guaranteed with KEMA-keur and GS (Geprüfte Sicherheit), approved by CEBEC

Touch control with Screen

• Centrally operates and reads the data from all Plugwise modules

• By simply touching the floor plan and on-screen ‘buttons’, appliances can be switched on and off

• Single glance status of the appliances and their energy consumption

Alternative energy

• Plugwise power meters can be used to measure energy production and report it with the energy used.

• Ideal for PV cells, small wind turbine, etc.

Dirty photo-voltaic cells produce less electricity. Such changes can become apparent if

the power production is monitored with Plugwise modules.

Smart grid

When capacity

shortage is imminent,

appliances can be

switched off

automatically.

Electric cars can be

charged at night and

can deliver energy to

the grid at times of

peak usage.

Energy will

partly be

produced and

distributed

locally. Street lights are

automatically switched

off at sunrise. During

the day they producte

energy via PV cells.

Power plants can

produce electricity

more efficient

because

consumption is

more evenly spread

A typical use case

• No room in a building, whether home or office, is in use all the time

• In this case only 38% percent of the year sees activitiy and during the rest of the time many devices like lights, PCs, printers, coffee machines are left operational - wasting energy

Phases of a customer Implementation

Pre Installation Phase

•First Meetings

•Costing Established

Phase 1

•Day 1 - Day 14

•Understand the Energy Used

Phase 2

•Day 15 - 30

•Measurement and Control – set up the Plugwise system

•Go - No Go

Customer agrees to an Installation

• Money back guarantees

Customer Enjoys up to 40% savings in Energy Use

• ROI in 1 to 3 years

Be wise, plug in.

Pre Installation• Focuses on creating a clear picture of the costs, where and what type of

device can to be used to save power.

• A "standard" pre-installation process will begin with a meeting to present

Plugwise & allow us to fully assess the scale of the project and give a good

estimate to produce a tender with costing and ROI times.

• Once the tender is approved we discuss how Plugwise can implement a

solution

• A second appointment will be also organized with Facility Management to

do an inventory check of the devices mostly likely to be wasting energy.

• We will fully evaluate the customer’s site and will indicate the types of

device to be used and where they can be located to give 95% coverage of

the location.

• The final step is to ensure the customer fully understands the Plugwise

proposal in order to sign an agreement for its implementation.

Be wise, plug in.

Phase 1• Understanding the energy used by the customer.

• Measurement of energy only to get a good understanding of how to optimise the programming of the system– The plugs are not programmed in this phase and just act as autonomous energy

measurement devices to record all energy measurement in their Flash memory.

• After 2 weeks of pure measurement, a review date will be scheduled. The largest energy consuming devices will be identified, energy consumption will be measured against known averages and potential savings will be shown and explained.

• Immediately after this first review the switching schemes are implemented on all the plugged devices and names and grouping established.

Be wise, plug in.

Phase 2• Minimise energy consumption by programming the monitoring and

control functions of a number of key plugged devices identified from Phase 1

• This is made possible by programming the on / off times of the Plugwise system via the source software and activating standby killers in the device.

• Additionally it’s possible to get feedback from Phase 1 on the most efficient use of energy to users & initiate behavioural change within the company.

• After the Phase 2 review a clear picture of the energy consumption of the devices outside office hours will be given and lists made of the top 20 largest energy wasters.

Be wise, plug in.

Final Phase

• At this stage customers decide whether the Pilot of the Plugwise system has been convincing enough to be implemented in either in full or part.

• After a 'GO' separate arrangements will be made for the expansion and or optimization of the system.

– This will normally be within 2 weeks of final sign off.

Average Consumption per day (kW)

Consumption per day

• In this diagram the Plugwise measurement phase shows the peak power usage by day through a typical week

• This revealed high peaks at the start of the week during a high cost power period.

• This initiated 2 actions

– Behaviour change to level out the peaks to avoid high cost power

– Plugwise switching schedules to stop waste outside of working hours

Be wise, plug in.

Top 20 Users

• In this case the Plugwise Measurement phase is showing the top 20 energy consumers– Blue is working hours

– Brown is non working hours

• This immediately shows where we can take action to save energy and can program our devices to save power

Be wise, plug in.

Programming

• Once you have identified the high energy wastage its easy to program Plugwise’s Source to switch and control the devices in the network.

• You can schedule standby killer thresholds and switch devices on and off down to 15 minute intervals

Results

• We typically save customer between 10% and 40% of their energy costs over a year based on current fuel costs

• Savings come from– Lighting control

– Workstations with PCs / Monitors
