  1. Fachgruppe DARK SKY News from Germany: competition: energy efficient city lighting petition on light pollution Wien, 22nd August 2008 Andreas Hänel Planetarium, Museum am Schölerberg, Osnabrück

  2. Federal competition • energy efficient city lighting • part of Climate Protection Initiative • sale of emission allowances • Federal Ministry for the Environment, Nature Conservation and Nuclear Safety • Federal Environment Agency • KfW Förderbank

  3. energy efficient city lighting • execution by: • Berliner Energieagentur • starting point: • 1/3 of street lighting older than 20 years • 3-4 mrd. kWh/year electricity • > 2 mio. t CO2 • modern technique to reduce CO2 and • get better illumination • municipalities have no finances

  4. Light Pollution 2007: Dark Sky D: letter to ministry: energy saving, but also reduction of light pollution: reduce glare of modern lamps (MH, NAV, LED) reduce scattering of horizontal light -> full cut-off luminairies, class G6 like "bomb" in ministry! jury with representatives of „relevant organisations“

  5. 1. Technology competition June 19th - July 25th 2008 What is best technology? Who can participate?:Manufacturers, contractors, energy supplier

  6. 1. Technology competition time of use 4000 h/yr: 1600h at 100%, 1400h at >50%, 1000h at >20% no switch off! illumination situationstreets of different types with 1 km according to the norms (0.5, 1,0 cd/m² and 5 lux, EN 13201)

  7. 1. Technology competition point system 0, 1, 2, 3 reduction of light at lower temperature (25° -> 5°C) efficiency ULOR 0.00 missing!

  8. 1. Technology competition energy use /km/year(also CO2 emission) 1 cd/m² < 8000 kWh/km/a 0,5 cd/m² < 5000 kWh/km/a 5 lx < 4000 kWh/km/a energy amount/amount of light < 10 kWh/1000 klm*h

  9. 1. Technology competition: costs maintenance cycles (years) total costs = investment + energy + maintenance (no personal) environment: 1 point for lamps with less blue (insects)

  10. 2. municipality competition starting fall 2008 municipalities that use energy efficient, economic and high quality lighting will get funds • missing: • no ranking! • no full cut-off • mix of luminairies and lamps

  14. Posttower since 11th Aug • "Skybeamer" auf dem Dach wird ausgeschaltet. • "mesh walls" im Turm-EG werden ausgeschaltet. • Turm-Illumination: blauer flächiger Hintergrund mit "schwarzen" animierten Vogelsilhouetten, zwischen 22:00 und 01:00 Uhr (Dauer wie das bisherige Standardprogramm). • Jalousien am Turm werden nachts herabgelassen, um die Notbeleuchtung der Flure nach außen hin abzuschirmen (verringert auch die Intensität der Illumination). • Dauer des o.a. Beleuchtungsregimes: jährlich 1.8. bis 1.11. und 1.3. bis 1.5.

  15. industrial lighting Bruchsal • reduction of light • black phone for amateurs • no legislation exists!
