Reduced energy consumption does not mean that Oslo is becoming a darker city, quite the reverse.

Reduced energy consumption does not mean that Oslo is becoming a darker city, quite the reverse.

The project «Dynamisk gatebelysning» (Dynamic Street Lighting) can reduce the energy used for street lighting by 70%, without making the city darker. The solution is to adjust the need for lighting:

  • Heavy traffic will reduce the need for lighting, and the lighting will be softened.
  • Snow will reflect light and therefore less lighting will be needed.
  • New technology regulates the lighting according to seasonal changes.

Intelligent

Intelligent lighting creates less CO2 emissions and contributes to reduce global warming. This solution also creates other opportunities:

  • Increasing traffic safety
  • Prevention of crime
  • Reducing operation and maintenance costs by 50%
  • Better public services
  • Less light pollution

How does it Work?

By changing only the fittings in the poles and replacing the old light bulbs with economy bulbs. Every lamp gets a chip and therefore a unique address, this way we can control every individual lamp or send a series of lamps the same message through a computer. By doing so, we are able to use street lights efficiently and as required. The existing cable network will be used for communication.

An Illuminating Example

In April 2006, Oslo got the prestigious «GreenLight Award». The GreenLight programme is a voluntarily programme under the auspices of the EU. The goal is to reduce costs and improve lighting quality.
