Saving the environment and saving money can be as easy
as flipping a switch. That means you’re on the front line
for energy-saving opportunities. Team up with co-workers
to spot ways to reduce the energy your lighting system
uses – it’s good for the environment and good for the
bottom line.
Shine a spotlight on lighting costs
Check out your facility: Are the lights in each area
appropriate for the work performed there? Are more
energy-efficient lights available? Inspections can shed
light on these and other opportunities to conserve energy
and cut costs. There are three main areas to consider:
1. Housekeeping
› Turn off lights left on in unoccupied areas. It sounds
simple, but it takes teamwork to make sure unneeded
lights are turned off.
› Switching off unneeded lights scores big savings in
electricity. It also cuts your air-conditioning bill and the
refrigeration load in coolers and freezers.
› Turn off:
› Incandescent lights that aren’t needed
› Fluorescent lights when they’ll be off for at least
15 minutes
› High-intensity discharge (HID) lights when they’ll be
off for at least an hour
› Consider installing timers, photocells and occupancy
sensors. Or integrate the lighting system into an energy
management control system.
› Dust and grease on lighting fixtures can reduce the light
that reaches the target area by as much as 30 percent.
› Clean fixtures at least every two years. Clean them
more often in greasy, dusty or smoky places and when
the heat they generate is part of a heating, ventilating
and air-conditioning (HVAC) system.
2. Low-cost opportunities
› Where possible, remove lights. Make sure unused light
ballasts are also disconnected – they use electricity
even when the bulb is removed.
› Install dimmers. For example, plant production areas
can be fully lit during production periods and dimmed
when cleaning and security staff are on duty.
› Reducing general lighting while increasing task or
workstation lighting often boosts the occupants’ comfort
while cutting electricity costs.
3. Retrofits
› Blow the whistle on energy-wasting lights. Retrofitting
usually pays back within a reasonable amount of time
because it cuts electricity costs. And new equipment
automatically complies with the Energy Efficiency Act
and Energy Efficiency Regulations, which set minimum
requirements for lamp efficacy and lighting quality.
Evaluate your lighting system
1. Are unnecessary lights turned off?
5. Are large spaces with high ceilings lit with inefficient
fluorescent lights?
❏ Yes
Consider replacing fluorescents with
high-efficiency fixtures.
Train staff to turn lights off.
❏ No
No action required.
Install timers or sensors to turn lights off
Done by: ______________________________________
❏ Yes
Recheck periodically.
❏ No
Consider a lighting management system for
your facility.

6. Are large areas lit with mercury vapour lights?
❏ Yes
Consider replacing mercury vapour lights with
more energy-efficient ones.
❏ No
No action required.

7. Do all light fixtures meet the requirements of the
Energy Efficiency Act?
❏ Yes

❏ No
Consult a lighting expert.
3. Are light levels appropriate for each area?
Done by: ______________________________________
❏ Yes
Recheck periodically (if possible, use a
light meter).
