2014 Energy — Honourable Mention
Borough of Saint-Laurent, Quebec
LED Street Lighting Project
|Population:||Project duration:||Total project value:|
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.
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.
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.
