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

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“
