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.

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. 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. 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

  • 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. 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
