  1. Upgrading of streetlight installations Users guide Tor Mjøs Norconsult AS

  2. Index • Huge savings potetials • Organizing outdoornlighting • How to get started? • Adaptive lighting • Purchase - an important function • Lighting calculations • Support schemes

  3. European Market • Overall saving potential 38 TWh/Year • Replacing old installations reduction 37 % • Dimming and regulating another 45 % • Total effect: 66 % • Oslo case (savings before “active dimming”) • 117 units (2003) - Pilot project (67 % savings) • 2.000 units (2004) - Full scale test project (62 %) • 4.000 units (2005/6) - Full scale project (52%)

  4. Huge savings potential • 50-70 % savings • Symbolic value • Dimming • Environmental aspects • Safety • Prevention of crime • Public services • Utilize free electricity market • Improved maintenance level

  5. Huge savings potential • Technology available • Increased performance of the luminaries • Dimming High pressure Sodium and White light (yellow light + CDM) • Short pay-back times • LCC- calculations • Adm. matters

  6. Organizing outdoor lighting • Establish local guidelines • National standards • Quality standards • Level of light (lux, candela/m2) • Avoid light pollution • On/Off and dimming strategies • Energy metering • Communication • Electricity tariffs

  7. How to get started • Road complexity • Traffic volume • Road construction • Accident rates (if available?) • Existing columns • Today’s running costs? • LCC - Life cycle calculation • EN 13201 • CIE 115 Recommendations for streetlighting

  8. Upgrading installations • Reduction of running costs • Initially save lamp shift • Less maintenance • Less electricity losses/ increased capacity on existing grid • Increase performance • Digital communication

  9. Adaptive lighting • New standards opens up for adaptive lighting • Traffic volume • Traffic speed • Weather condition: • wet/dry road surface • asphalt / concrete • Snow? • With dimming: Figures according to light output performance of the lamp

  10. Purchase - an important function • Good planning - good solution • Investment horizon: 20 years • Open technology • Common products (E27/40 socket) • Technical specifications • Again, LCC calculations - losses and performance of the solution offered …

  11. Lighting calculations • Calculation • Independent computer programs • Present road geometry and surface • Verification • The lamp/reflector used under calculation must be equal to the one delivered • Evaluation • Field verification (lux)

  12. Finance and Support Schemes • Private Public Partnership • EU? • Others?
