Check Door Seals on Refrigeration Units
Tight seals and properly closing doors prevents warm air from entering the unit, reducing energy required for cooling as well as preventing frost build up. If you can easily slide a dollar bill into the seal, have the seal adjusted.
Cook Wisely
Ovens tend to be more efficient than rotisseries, griddles more than broilers. Examine your cooking methods and menu to find ways to utilize your energy-efficient appliances more frequently.
Clean Refrigeration Cooling Coils
Dirt impairs proper heat transfer and lowers a refrigerator’s efficiency and capacity. As you clean, watch for and remove any accumulation of ice.
Maintain Air-Gap on Refrigeration Units
Maintain an air-gap of at least three inches between the wall and the back of refrigerators, water coolers and freezers.
Cut Equipment Idle Time
Implement a startup/shutdown plan to make sure you are using only the equipment that you need, when you need it.
Shut Refrigeration and Freezer Doors
Keep the cooling unit doors closed as much as you possibly can. Repeated temperature fluctuations not only increase energy costs, it can damage food quality too.
Run Full Dishwashers Only
Use dishwashers only when full to conserve energy, water and detergent.
Improve Walk-In Refrigerators
Add strip curtains and automatic door closers to your walk-in refrigerator. Inexpensive and easy-to-install strip curtains can cut outside air infiltration by about 75 percent.
Install ECMs on Fans
Install electronically commutated motors (ECM) on evaporator and condenser fans to reduce fan energy consumption by approximately two-thirds.
Buy Large Ice Machines
Bigger ice machines are typically more efficient than smaller ones, yet the price difference is usually not very large. Choose well and you could get twice capacity at half the energy cost per pound of ice. Avoid water-cooled ice machines because of their high water-usage costs, which makes them significantly more expensive.
