2 Presentation Contents Introduction Environmental Background Saving Energy for Retrofit Defining the Concepts Choosing the Technology Correct Implementation Case Studies / References About Us Contact

3 The state of the Energy Environment

4 Global Bio-Capacity Source: Living Planet Report 2008

5 UAE Carbon Footprint Source: Living Planet Report 2008

6 Defining the Concepts to Save Energy: E.E.S.S.

7 Applying E.E.S.S. Lighting If no-one is present Turn the lights OFF!

8 Applying E.E.S.S. HVAC If no-one is present Turn the Temperature HIGHER!

9 Applying E.E.S.S. HVAC If the window is open Turn the Air Conditioning OFF!

10 Applying E.E.S.S. Energy Measurement If you know how much you are using You know how much you can save!

11 Applying E.E.S.S. Daylight Harvesting If it s bright outside Dim the lights inside!

12 Applying E.E.S.S. Motion Control Because we forget we need to automate it!

13 Choosing the right Technology for Retrofit!

14 Traditional Systems for new Buildings Actuators light access air buttons windows day light DALI, 0-10V, Digital,... LON, EIB, Analog... LON, EIB, Analog,... EIB, Digital... e-drive, Analog, Digital LON, 0-10V, Analog,... Communication Control A B C D E F Converter CPU main control

15 The Retrofit Challenge In order to use Energy Saving Solutions in existing buildings there can be no complex control system wiring = An electrician should be able to install and maintain the solution! = Lower Initial Cost Lower Maintenance Cost

16 The Retrofit Solution Stand-Alone or IP Enabled or Wireless / Batteryless

17 Stand-Alone - Day / Night Switching Day/Night Switching Lux Sensor Automatically detects amount of sunlight available and turns lighting on after dark

18 Stand-Alone - Motion Sensors

20 EnOcean: Self-powered Wireless Technology Wireless sensor modules harvest their power from their surroundings: linear motion, light or temperature difference. efficient energy converters, ultra-lowpower electronic circuitry and a reliable interoperable standard wireless protocol. wireless telegrams are just one millisecond long. Signal transmission: 868/315 MHz license free frequency band (worldwide coverage).

21 Energy Harvesting Sources for Wireless Sensors Mechanical Solar Thermal Vibrations (production) Rotation Radio waves Air pressure changes Muscle contraction Blood sugar fuel cells Organic material (demonstration) (future)

22 Mechanical Energy Harvesting Product Examples

23 Light Energy Harvesting Product Examples

24 The EnOcean Standard > 150 Companies supporting > 350 Interoperable products > 100,000 buildings deployed Award Winning Green Technology IEC Standardization THE ONLY WIRELESS STANDARD CAPABLE OF ENERGY HARVESTING

25 Implementing the Technology!

26 Sensors Choosing the right sensors for the application!

27 Sensors Choosing the right sensors Application Requirement Wiring Space Restrictions Design

28 Sensors Choosing the right technology:

29 Sensors Choosing the right location: In rooms, sensors are placed in corners to cover the entrance in the best possible way If you walk straight into the sensor zones, the sensors will be less sensitive and thus scan out through any open doors.

30 E.E.S.S. With Wireless Technology Example: Wireless/Batteryless Window Contact Hotel Room Solution Wireless/Batteryless Guest Card Holder Wireless Receiving Actuators for HVAC and Lighting

31 E.E.S.S. Payback Calculation Detailed Payback Calculations can be done upon request specific to the project and the demographical factors: PAYBACK CALCULATION EXAMPLE Hotel Room Package $ Cost of Electricty (kwh) Consumption Data: o Lighting, FCUs, Motors, Plant Equipment etc. Operating Hours Room Load Calculations HVAC (Watt) 400 Lighting (Watt) 600 Total Load (Watt) per Room 1,000 Hours Usage per Day - No System 16 Days 365 Hours per Year 5,840 Total kwh 5,840 Cost per kwh 0.10 USD 0.37 AED Total Energy Cost / Year without System USD 2, AED Hours per Day - With E.E.S.S. System 8 Days 365 Hours per Year 2,920 Total kwh 2,920 Cost per kwh 0.10 USD 0.37 AED Total Energy Cost / Year with E.E.S.S USD 1, AED Cost of Products USD 1, AED Installation Add-On 20% Total Cost USD 2, AED Yearly Saving USD 1, AED Payback Period (Years) 2.12 Total number of Rooms 250 Total Savings over 5 Years (including cost of System) 210, USD 772, AED

32 Case Studies: Retrofit

33 Kempinski Hotel, Ajman Lighting Control (lobby, bar areas) Automatic -based on natural light Savings 60% Lighting Energy Costs Ajman, UAE (2008)

34 Jebel Ali Golf Resort & Hotel In-Room Lighting Control In-Room Climate Control Based on occupancy & window status Expected Savings 20% Energy Costs Retrofit Costs Dubai, UAE (2009)
