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

3 3 European Market Overall saving potential 38 TWh/Year uReplacing old installations reduction 37 % uDimming and regulating another 45 % uTotal effect: 66 % Oslo case (savings before active dimming) u117 units (2003) - Pilot project (67 % savings) u2.000 units (2004) - Full scale test project (62 %) u4.000 units (2005/6) - Full scale project (52%)

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

5 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 6 Organizing outdoor lighting Establish local guidelines uNational standards uQuality standards uLevel of light (lux, candela/m2) uAvoid light pollution uOn/Off and dimming strategies uEnergy metering uCommunication uElectricity tariffs

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

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

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

10 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 11 Lighting calculations Calculation uIndependent computer programs uPresent road geometry and surface Verification uThe lamp/reflector used under calculation must be equal to the one delivered Evaluation uField verification (lux)

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