pened in the 1980's, 4890-4898 Taschereau Boulevard is a busy, multitenant retail building located in Greenfield Park, Quebec. The twofloor, 36,984-sq.-ft. facility houses a variety of well-known Canadian

brands and is owned and operated by BTB REIT, Montreal (btbreit.com), a realestate investment trust that owns 70 commercial, office, and industrial properties
in eastern Canada.
BTB is known for its focus on providing comfort and safety in a well-maintained
environment for its tenants and customers. To this end, the property manager understood the importance of an exterior that is well illuminated in the evening,
providing visibility and a sense of security for building tenants and visitors.
The company also takes sustainability seriously and actively seeks ways to reduce energy consumption. Converting older, energy-sapping lighting to more modern and efficient LED alternatives is one way BTB management achieves this goal.
When it came to refreshing the Taschereau Boulevard parking lot and signage, a
win-win scenario involved replacing aging high-pressure sodium (HPS) and
metal-halide lighting with energy-efficient and modern LED fixtures.
BTB selected Concept Illumination, Montreal and South Burlington, VT (conceptillumination.com), as its lighting partner. To revitalize the building's exterior,
the lighting team assessed the site and worked through the project with BTB representatives.
The renovation included pole-mounted parking-lot lighting for general illumination of the exterior area, improving security and the aesthetic. Seventeen 400-W
fixtures-a mix of HPS and metal halide-were replaced one-for-one with 160-W
LED fixtures. The lighting company also replaced a damaged pole, repaired a base,
and painted all existing poles black and all bases yellow.
Wall packs on the building's exterior were replaced. Ten 175-W wall packs were
replaced by ten 50-W LED products, and two 400-W HPS fixtures were removed in
favor of 80-W LED equivalents to reduce energy while improving security.
Finally, the pylon sign, one of the most visible aspects of the building's exterior
and illuminated by 20 96-W, 8-ft. T12 fluorescent tubes was re-lit with 20 48-W
double-sided LED lightbars. Fluorescent ballasts were replaced with LED drivers.
"With both the parking lot and the exterior wall packs, the white of the metal
halide competed with the orange color of the high-pressure sodium resulting in a

patchy, unbalanced appearance," said Daniel Herz, who headed the project for
Concept Illumination. "When we replaced them with the newer LED fixtures, we
were able to achieve a much more even 4000-K illumination, which greatly improved the aesthetics."
The savings are expected to be significant.
After replacing the old fixtures with the new LED fixtures, it is estimated that
the building will realize a 68% reduction in energy use, a reduction from about
59,000 kWh to approximately 19,000 kWh. All of the new lighting products have a
ten-year warranty.
"Our intent was to save on energy costs while improving the aesthetic of the
property," said Madeleine-Jane Brammer Lavoie, property manager and sustainability officer for BTB. "We are very satisfied with the significant savings and the final
appearance." CA
