  • 2. We can account for most of our expenses EXCEPT • Gas • Water • Electricity Be wise, plug in.
  • 3. Energy consumption in professional environments During office hours Outside of office hours Based on over 100 projects with Dutch professional customers. Be wise, plug in.
  • 4. Amount Saved • depends on – the cost of Electricity – The number of hours worked – The number of devices left operational after hours – The number of devices left on standby – The type of product using power Be wise, plug in.
  • 5. Our mission To develop a reliable and energy-economical network & sensor technology to enable the measurement and control of energy to ensure none is wasted. Be wise, plug in.
  • 6. Plugwise • Founded on December 29th, 2006 • Entire development-process leading up to new affordable and reliable network- & sensor technology in only 24 months (Kema, GS, Cebec) • State-of-the-art-manufacturing in the Netherlands (by partner AME) • Elected member of the of the Dutch Koplopers Loket of the Ministry of Economic Affairs. • Small, flexible organization with maximum outsourcing and automation of manufacturing and logistics. • Currently with 17 FTE in NL, 2 in Germany, 1 in the UK, 1 in the US, and 10 external engineers (AME) Be wise, plug in.

  • 10. Wireless mesh network 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). If for any reason the route is blocked… …the system will automatically choose the second most efficient route. Be wise, plug in.
  • 11. The wireless mesh network Plugwise networks can easily be extended with other modules. Be wise, plug in.
  • 12. ZigBee technology ZigBee 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.
  • 13. Certifications • Compliance with European R&TTE directive confirmed by TüV Rheinland • Safety and electro-magnetic compatibility (EMC) guaranteed with KEMA-keur and GS (Geprüfte Sicherheit), approved by CEBEC Be wise, plug in.

  • 15. 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 Be wise, plug in.
  • 16. 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. Photo: Coolstock Dirty photo-voltaic cells produce less electricity. Such changes can become apparent if the power production is monitored with Plugwise modules. Be wise, plug in.
  • 17. Energy will partly be produced and Smart grid distributed locally. Street lights are automatically switched off at sunrise. During the day they producte When capacity energy via PV cells. shortage is imminent, appliances can be switched off automatically. Power plants can produce electricity more efficient because consumption is more evenly spread Electric cars can be charged at night and can deliver energy to Plugwise Stretch the grid at times of peak usage. with UMTS Be wise, plug in.

  • 30. Phases of a customer Implementation •First Meetings Pre Installation •Costing Established Phase •Day 1 - Day 14 •Understand the Energy Used Phase 1 •Day 15 - 30 •Measurement and Control – set up the Plugwise system Phase 2 •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.
  • 31. 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.
  • 32. 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.
  • 33. 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.
  • 34. 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. Be wise, plug in.

  • 37. 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.
  • 38. 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 Be wise, plug in.
  • 39. 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 – TVs / Monitors – Printers / Copiers – Vending systems ( where they are not refrigerated ) – High power devices left on over night Be wise, plug in.
