Reconfiguring Lighting for Energy and
Materials Savings at Canadian Tire By Ian Joffe
Efficient lighting installation contrib- utes to the sustainability of a proj- ect. Selection of efficient lighting fixtures and lamp sources, mounting heights of the fixtures, and orientation
of the luminaires can reduce total installed
lighting power density while maintaining
visual brightness in the sales area and consistent light levels, as they did for Canadian
Tire’s new store in Bowmanville, Ontario.
The project received an Outstanding Merit
in A. R.E.’s 2012 Sustainability Awards.
Retail stores typically switch their lights
on in the morning and off at night, using
limited switching for daylight control and
light level reductions for power demand
response. Based on the number of “starts
per day,” Canadian Tire chose T8 fluorescent lamp technology for its excellent lamp
life, three-year manufacturer’s warranty
for lamps and five years for ballasts, low
cost of lamp replacement, and availability
of low-mercury lamps. Lighting vendors
had worked with the retailer and Toronto-based Hammerschlag + Joffe Inc. to produce highly efficient, glare-free luminaires.
With the number of lamps per fixture
and lamp wattages already reduced, the
design team was challenged to further
reduce the lighting power load while main-
taining lighting levels. The team turned its
attention to light fixture mounting height
and orientation of the luminaires.
