• Use LED bulbs and LED exit signs
• Install dimmable ballasts to lower energy use in fluorescent lamps
• Install inexpensive occupancy sensors that turn lights off
• Install sensory controllers on vending machines

Install an Uninterruptible Power Supplies (UPS) system to provide emergency power when the input power source fails to provide near-instantaneous protection from interruptions by supplying energy stored in batteries, super capacitors or flywheels.

Change refrigeration display case lighting to LEDs, found to be also more appealing to customers.

• Perform routine maintenance on heating and A/C filters, belts, coils and bearings
• Install programmable thermostats
• Install window film and blinds to keep the heat out
• Install variable speed drives to optimize fan and pump motor operation
• Repair air leaks in hoses and pipe connections

In new construction, downsizing mechanical cooling equipment and/or electrical supply can lower costs and mechanical/electrical footprint.

• For large data center facilities, a chilled water system served by a central plant is the most efficient approach to providing mechanical cooling.
• Check that data center cooling meets the latest ASHRAE standards for Datacom environments—many data centers can safely operate at higher temperatures than previous standards.
• In new construction, downsizing mechanical cooling equipment and/or electrical supply can lower costs and mechanical/electrical footprint.
• Uses of best-practices air management, such as strict hot aisle/cold aisle configuration, can double the computer server cooling capacity of a data center.
• Combined with an air-side economizer, air management can reduce data center cooling costs by over 60%.
• Install air-or water-side economizers to help cut data center cooling costs by over 60% using standard, commonly available low-cost equipment.
• Best-practices in air management, such as strict hot aisle/cold aisle configuration, can double the computer server cooling capacity of a data center.

• Maintain appropriate temperature settings in freezers (-8°F to -14°F) and refrigerators (35°F to 38°F)
• Turn down refrigerated storage and refrigerant compressors during Time- of- Use (TOU) On-Peak Hours and Critical Peak Pricing (CPP) events

• Clean evaporator coils
• Replace worn or missing door gaskets on refrigerated units
• Install refrigeration curtains, and/or auto door closers on refrigeration units
• Add temperature controllers to your refrigeration units
• Upgrade to high-efficiency fans and programmable thermostats
• Reduce air leakage in refrigerated cases
• Add strip curtains to walk-in doors

• Turn off ice machines and reschedule dishwashing/laundry processes before or after TOU On-Peak Hours and CPP events
• Delay use of electric resistance defrost controls and the use of anti-sweat heaters before or after TOU On-Peak Hours and CPP events

• Minimize preheating energy use by following manufacturer recommendations for preheat times and temperature settings
• Set cooking schedules to use cooking equipment at full capacity
• Turn off unused and backup equipment during low production periods and CPP events
• Reduce air leakage in ovens by making sure doors fit tightly and gaskets are in good condition

• Position cooking appliances well within exhaust hoods
• Minimize excessive preheating by following the manufacturer’s recommendations for preheat times and temperature settings

• Turn off vertical lifts, conveyor belts and non-essential process equipment during TOU On-Peak hours and Critical Peak Pricing (CPP) events
• Charge batteries and battery-operated equipment during before 4 p.m. and after 9 p.m. and before or after CPP events

• Turn off unnecessary lighting, ornamental or display lighting and office equipment
• Utilize day lighting options and reduce lighting levels
• Install photocells or time clocks on outdoor lighting systems so they only operate from dusk to dawn

• Manage evaporative fan speeds
• Reduce air compressors and processing loads using pre-programmed load shed strategies
• Reduce compressed air discharge pressure by 10 psi or at the lowest pressure allowed by your system.
• Match energy consumption to actual needs. Often, head pressure is left at a high set point determined by the peak design day. Refrigeration controls can modulate and reduce the head pressure, typically saving 3 to 15% annually*
• Let floating suction controls monitor ambient temperature
• By continuously varying suction pressure to meet demand, the savings can be significant, typically from 2 to 10% annually*
• Delay electric-resistant defrost controls
• Inspect weather stripping for deterioration or gaps around doors and windows

• Practice preventative maintenance on motor systems and replace old motors with high-efficiency motors for improved performance.
• Replace old motors with high-efficiency motors

• Install automatic shut-off devices to reduce peak
• Install small air compressors for low-use
• Install sequencing controls on multiple-unit compressor systems
