The Lighting Controls Innovation Award was created in 2011 as part of the Illuminating Engineering Society’s Illumination Awards program, which recognizes professionalism, ingenuity and originality in lighting design. LCA is proud to sponsor the Lighting Controls Innovation Award, which recognizes projects that exemplify the effective application of lighting controls in nonresidential spaces.
This month, we will explore the lighting control solution applied to a GO Ajax parking facility.

This six-storey parking structure featuring over 1000 parking spaces had to meet strict lighting requirements while meeting owner’s expectations for energy savings, and ensuring transit commuters’ safety.
The lighting design had to create a visually safe environment for commuters at all hours of the day and had to complement the stylish architecture, while developing an integrated energy efficient system.
LED fixtures were selected due to their long life, durability, energy efficiency, ease of control and maintenance.
Lighting controls are used extensively throughout the building. Due to its complexity, multiple relay control panels with timers and sensors (on/off and daylighting) are used to create a safe, functional lighting system with various time functions based on time of day use for the facility. Spaces with different functionality (e.g. the parking spaces, the tunnel, the exterior
platform) all require different lighting control strategies.
In the parking area, the lighting strategy is to turn off 50% of LEDs in each fixture during the off peak hours. In order to achieve this, the fixtures have been selected with dual circuit inputs. Lighting comes to full brightness during “on peak” hours and during off peak hours, when it detects movement in the garage. The design considers the occupants safety as utmost important. The perimeter fixtures are on separate relays and are controlled based on available daylighting.
The programming sequence in the underground tunnel reduces the light level by 50% during non-peak hours.
Daylight sensors are used to control the lighting around the perimeter of the building and in the glass stairwells to turn off fixtures during daylight hours.
This award winning building was completed on budget, has been well received by the community and the transit authority has adopted the lighting control strategy as the standard for all their future facilities.
