EkoLum : Smart Street Lighting Software

6,830 views

Published on

EkoLum is a remote control system for Street Lighting installations that provides an efficient diagnosis of the current state of each luminaire. Based on a point-to-point control architecture, the system reports in real time the alarms coming from the luminaires and allows the remote switching on/off and the dimming of the lamps.

  7. 7. Convergence of Environmental and Bottom Line factors 7
  8. 8. The Important Players in the Market Municipalities, city counsels and road authorities. Lighting companies that manufacture luminaires, ballasts and intelligent controllers The system integrators packaging the solution and selling it to the municipalities Service companies running outdoor lighting on behalf of the end-user Consultants that revolve around the governments 8
  9. 9. Benefits of a Networked, Infrastructure Approach Environmental - Dramatic reductions in energy use - Reduced CO2 emissions - Reduced light pollution - City Beautification Cost & quality of maintenance - Individual luminaire monitoring - Outage detection - Early failure monitoring Liability, security and safety - Real-time status reporting and monitoring - Historical performance data 9
  10. 10. Benefits of a Networked, Infrastructure Approach Not limited to single luminaire choice - Compatible with future lamp technology - Phased approach as existing technology rides the cost curve - HPS, LED, induction, metal halide Single, multi-purpose city network - Easily add future sensing devices Traffic, environmental, others… - Independent of wide-area network choices - Implement new services without changing the infrastructure Electric vehicle smart chargers 10
  11. 11. Positioning Municipalities and Road Authorities - Immense savings in energy consumption - Lowest maintenance cost possible - Increased safety and security - Make outdoor lighting environmentally friendly - Wide choice of interoperable solution providers and components, based on ISO 14908 and SOAP/XML communication standard 11
  12. 12. Positioning Public Lighting Service Providers - Lower maintenance cost - Increased service level - Increased customer control - Generate new revenue by providing additional e- street related services 12
  13. 13. Positioning Luminaires manufacturers - They (re)gain control of their customers by offering a total solution - Shortest time to market - Best way to play in a fast growing new market - System based on a reliable ISO standard technology 13
  14. 14. Main Elements of a Streetlight Network Extremely reliable power line light controller - Use existing city electricity wires for power and communications: no new wires needed - Standards-based signaling - Many suppliers on the market Aditel, Beta, Fulum, Kim, Romlight, SELC, Intron, Seiteco, Philips, etc. EkoLum Segment Gateway ® segment controller - Standards-based advanced bridge to IP networks - Power line network, meter interface, connection to future equipment - Powerful segment controller Installation and management central software - Automatic installation - Information flow management - Maintenance management 14

  16. 16. Distribution of Costs New Installation Field Installation Pole Luminaire Intelligent ballast PL Technology 25% 19% 50% 6% 0% 16
  17. 17. Typical Saving Calculations - Retrofit Hardware cost: $400 per pole (ballast, fixture etc) EkoLum $5 per pole (assuming 100 poles/segment) Segment Gateway ®: HMI software: $2 per pole (assuming 100 poles/segment) Installation costs: $50 (depends upon location) Cost per point: $457 Total cost: $45,700,000 (assuming 100k lights) Energy Saving $3,000,000 (assuming 60% reduction)* Maintenance Saving $3,000,000 *(68 million kWh/yr used by 100k lights @ $0,07/kWh) 17
  18. 18. Typical ROI Return on Investment = 7 years Energy savings breakdown - Control: ~40% – Modern optics: ~20% - Modern lamps: ~10% Other benefits not included: - Reduction in Carbon foot print: 25,000 metric ton CO2/year - Safety and Security on city streets - City beautification 18
  19. 19. Financing models Self-financed - City pays for the system and receives direct benefits Bank loan - Bank finances the system for the city and recover the investment with interests Service provider-financed - Service provider pays for the system - City keeps paying the SP what was paying before (energy and maintenance) - SP recovers the investment from savings in energy and maintenance 19

  23. 23. In the Street… Intelligent Ballasts Dimming - Configurable % increments Automatic failure identification Data collection Lamp burning hours Voltage, Current, Ballast Temperature, etc. Consumed energy (calculated) Standard Protocol for Communication - Utilizes ISO 14908-2 global standard - Bi- directional real-time communication 23
  24. 24. Most Common Types of Lamp Mercury Vapor - Very common - Being replaced because of poor energy efficiency HPS and MH - Second most efficient and are - Currently being used to replace MV lamps - Standard for traditional new installations and replacements - Poor CRI LPS - Most efficient - Very poor color rendering LED - Great CRI - Higher life span - Decreasing costs - Improving efficiency - Improving lenses/optics - More favourable power reduction normative 24
  25. 25. Lamp Replacement Strategy Typically mercury vapor lamps are used for street lighting and other outdoor lighting (car parks, etc) Lamps are bring replaced with energy efficient lamp High Intensity Discharge (HID) as follows: - For Street Lighting High Pressure Sodium - 200 to 400 W (Orange-White color Light) - For Warehouses, Outdoor & Parking Lots Metal Halides - 100 to 250 W (Natural White color Light) - Some cities (e.g. San Jose, CA) use For Street Lights - Low Pressure Sodium - 180 W (Yellow Light) 25
  26. 26. Types of Ballasts & PL Controller EMEA - 230V, 35W to 100W - Interface to ballst: serial, 1 to 10V, Dali, Madli, native PL US/Canada - 120V, 200W to 400W - Interface: serial, 1 to 10V, Madli, native PL Asia - 120 to 240 V - Interface = 1 to 10V, native PL 26
