BXL LIGHT

Thanks to new technologies, the light efficiency of buildings and roads is increased, while electricity consumption is reduced. The City of Brussels will install LED lighting and adjust it according to occupancy both in its buildings (existing and new) and on its roads. On roads, this approach will also make it possible to reduce night lighting in areas with very low traffic during off-peak hours.

The main project organiser:

OU Energy, OU Special Technologies, OU Studies (Road Works dept.)

OBJECTIVES TO BE ACHIEVED:

  • 100% of public buildings fitted with LEDs and efficient lighting systems (presence/absence detectors, by zone and dimmer/variable lighting power).
  • 100% of roads with LED lighting.
  • Reduction of 50% in lighting-related consumption.

Expected reduction of CO2: 26.2 t CO2/year

Other impact(s):

  • Socio-economic: night-time security on roads or in streets, well-being.
  • Cultural: lighting of heritage assets, façades.
  • Environmental: protection of flora and fauna (night-time lighting reduced while ensuring security).

FOLLOW-UP AND EVALUATION INDICATORS:

Follow-up indicators:

  • reduction of electricity consumption and % of reduction in electricity consumption by lighting.
  • Lighting power Before/After: % of power decrease.
  • Number of sites fitted.
  • Number of streets fitted.

Results indicators:

  • Electricity consumption per building and for public lighting, per m², per occupant.
  • Power of the LEDs installed.

Budget: €3,040,000
