2014 Energy — Honourable Mention

Borough of Saint-Laurent, Quebec

LED Street Lighting Project

Population:  Project duration:  Total project value:

93,842

2012-2013 $785,114

In 2006, the Borough of Saint-Laurent equipped its traffic signals with light emitting diode (LED) lights. A few years later, as part of upgrades to other street lamps, the borough asked the City of Montréal to provide metal halide (MH) lighting. However, this type of lighting did not meet requirements in the area, despite some technological advantages, and the borough decided on LED lamps for future street lighting. In April 2013 LED lighting was installed on Alexis-Nihon and Toupin boulevards, and has also replaced conventional lighting in parks and along pathways.

Taking an innovative approach for the two boulevards, the borough asked interested suppliers to experiment and design a custom, adjustable lighting system with variable intensity levels — options that weren't available at the time. This initiative has resulted in new technology for the region, applied for the first time and on a large scale.

Results

Environmental Economic Community
  • 40% reduction in energy consumption, according to Hydro-Québec

  • Light pollution reduced by 16,800 watts on Alexis-Nihon Boulevard, and by 18,600 watts on Toupin Boulevard

  • Longer life cycles for LED street lamps (10 to 15 years) compared with sodium high pressure street lamps (average 6 years).

  • Lower costs as LED street lamps fell from $1,200 each in 2007 to $450 in 2013

  • LED lighting provides better control over light beams, greater comfort and safety for residents and road users, and excellent visibility

Challenges

  • Electricity costs are relatively low in Quebec and energy-efficient power sources are widely used, so actual cost savings may be minimal for this type of project.

  • Variable lighting systems were not available at the time, challenging suppliers to design these products.

  • The project team relied on the city's and the borough's sustainable development policies to convince  stakeholders — including  executives, planners, operational staff and the general public — of the benefits of LED technology.

Lessons learned

  • Saint-Laurent's experience can help other municipalities save money and learn about direct-to-LED lighting conversions.

  • Complete photometric calculations in advance to ensure desired lighting levels; perceived brightness is usually higher with LED street lamps (by about 30 per cent).

  • Political will and commitment to sustainable development were vital to the project's success.
