Low-cost and no-cost solutions
There are many ways you can improve the energy efficiency of your facility and reduce your energy costs. We offer a variety of low-cost and no-cost solutions in addition to a selection of Power Smart programs that will help you reduce your building’s energy consumption.
Setup, stocking, and operating tips
- Optimize the location of compressors, condensers, and refrigeration equipment by locating in cool surroundings, avoiding direct sunlight.
- Avoid drafts on open display cases.
- Size refrigerators and freezers properly to avoid over or under loading.
- Follow manufacturer recommendations for shelf position and size.
- Don’t overfill refrigerators and freezers, a 2.54 cm gap on the sides and 10.16 cm gap at the back allow access to a steady flow of air.
- Check the temperature settings, if settings are lower than necessary, you’re wasting energy.
- Don’t let refrigerated items sit and warm-up during delivery and restocking, load product when cool.
- Keep the doors closed as much as possible.
Maintenance and prevention tips
Schedule regular maintenance checks with your service company.
- Clean debris from evaporator and condenser coils.
- Check and service belts, filters, compressor lines, gaskets, door latches, fan blades, and refrigerant charge.
Equipment controls and features to consider
Consider ENERGY STAR® certified equipment as they are designed with more energy efficient components that will significantly reduce energy consumption and utility bills.
- Ask your supplier about energy efficiency features and energy consumption.
- Avoid heat build-up by using as few lights as possible to illuminate refrigerated space interiors.
- Install motion sensors to turn off lights in unoccupied refrigerated areas.
- Talk to your service company about the possibility of: higher suction pressures, lower condensing pressure and floating head pressures.
- Set operating temperatures as low as necessary, check regularly to maintain consistent temperatures, set thermostat to avoid over-cooling merchandise.
- Install sensors to monitor product temperature instead of air temperature in the cold storage areas.
Employee education and training
- Post signs to remind workers to turn off lights and shut doors.
- Discuss energy conservation measures in staff meetings.
