Warehouses

Warehouses often generate excessive energy waste. Cut energy costs, improve your operational performance and enhance employee comfort with these tips.

Savings Opportunities: Peak Demand Management

Discover ways to maximize energy savings and manage demand. An improved building environment can also increase productivity, safety and employee health.

Time of Use

• Charge forklift batteries during off-peak hours.
• Use an energy management system to coordinate load shedding from one central location.

Energy Intensity

• Replace legacy lighting with LED lighting.
• Upgrade motors to NEMA Premium level.
• Use high-volume low-speed fans in lieu of air conditioning.

Ready to lower energy costs and reduce your environmental impact? Check out these tips to improve efficiency in each area of your warehouse facility:

Lighting

• Purchase indoor lighting with an 80+ CRI color quality rating.
• Replace fluorescent lamps with LEDs and save 30% or more.
• Use high illumination levels and high color temperature (4000K or higher) for storage areas.
• Use lower illumination levels and lower color temperature (less than 3000K) for offices and lobbies.
• Take advantage of natural light with skylights.
• Install occupancy sensors that respond to the presence of forklifts.

Motors

• Upgrade to NEMA Premium motors.
• Use variable-frequency drives (VFDs) for variable torques loads, such as moving air and liquids.
• Replace legacy motors with inverter-rated motors when using VFD controls.
• Right-size motors to maximize efficiency and improve power factor.
• Keep voltage imbalance at less than 3% for three-phase motors.
• Use AC synchronous permanent magnet motors for best efficiency.

HVAC

• Adjust thermostat settings during non-working hours.
• Seal cracks around windows, doors and pipe/conduit pass throughs.
• Practice preventive maintenance to save energy and avoid frequent system breakdowns.
• Replace older air conditioning units with energy-efficient models and save 30% or more.
• Add or ensure proper operation of economizers to pull in cool outside air.
• Use infrared heaters in high-bay and loading dock areas.

Compressed Air

• Identify and fix leaks.
• Stop using compressed air for cooling or moving products.
• Use VFD controls for trim units in conjunction with full-capacity baseload units.
• Keep pressure drop from the receiver tank output to the point-of-use to less than 10%.
• Use master controls to coordinate the use of multiple compressors, adapt to demand, perform advanced energy management, and enable advanced monitoring and communications.
• Reduce system pressure. Reducing pressure by 10 psi saves 8% to 10%.
• Use compressor heat recovery to reduce space or water heating costs.
