If you run a small retail or office-based business, lighting is probably your biggest energy expense. To lower your electricity costs:
Install energy-efficient compact fluorescent lamps (CFLs) — they provide the same intensity and warmth of incandescent lighting at a much lower cost. Replacing one 60-watt incandescent bulb with a 13-watt CFL will save about $37 over the 8,000 hour life of the bulb. CFLs also give off less heat, so they help control cooling costs.
Replace standard T12 fluorescent tubes with high-efficiency T8 and T5 models — they last up to 16 years, are warmer, and need less maintenance. They also use electronic (not magnetic) ballasts, which eliminates any hum or flickering.
Install occupancy sensors and dimmers in low-traffic rooms like washrooms, break rooms and conference rooms.
Install a programmable thermostat. Save up to 10% on your energy bill!
Use recommended thermostat set points. In summer, set the thermostat at 25°C during work hours and 28°C after hours; each degree you raise it can lower your air conditioning costs by up to 2%. In winter, set it at 20°C during work hours and 17°C after hours.
Make your business more efficient with insulation, weatherstripping around doors, and shades, awnings or tinting over windows.
Use ink-jet printers — they consume less energy than laser printers.
Use energy-smart power strips that sense when equipment is not being used.
