| 1 |
Convert to LED High-Bay Lighting |
Replace fluorescent, metal-halide, or high-pressure sodium fixtures with high-efficiency LED high-bay luminaires. |
40–70% of lighting electricity |
2–5 years |
Lighting power density: approximately 0.4–1.0 W/ft² |
Confirm illuminance levels, ceiling height, temperature rating, glare control, and compatibility with existing electrical circuits. |
| 2 |
Install Occupancy and Daylight Controls |
Use motion sensors, zoning, dimming, and daylight harvesting to reduce lighting in vacant or naturally lit areas. |
20–50% of lighting electricity |
1–4 years |
Operating hours reduced during unoccupied periods |
Use separate control zones for aisles, loading docks, storage areas, offices, and maintenance spaces to avoid unnecessary shutoffs. |
| 3 |
Optimize HVAC and Ventilation |
Schedule heating and cooling, maintain setpoints, use variable-speed drives, and adjust ventilation to occupancy and process needs. |
10–30% of HVAC energy |
2–6 years |
Heating and cooling energy per floor area |
Seal air leaks, maintain filters, use destratification fans where appropriate, and avoid conditioning unused warehouse zones. |
| 4 |
Improve Dock Doors and Building Envelope |
Install high-speed doors, weather seals, insulated panels, and automatic door closers to reduce uncontrolled air exchange. |
5–20% of heating and cooling energy |
2–7 years |
Door-open time and infiltration-related load |
Prioritize frequently used dock doors and inspect gaps around doors, roof penetrations, windows, and wall joints. |
| 5 |
Use Efficient Material-Handling Equipment |
Replace inefficient equipment with electric or high-efficiency models sized for the actual load and duty cycle. |
15–35% of material-handling energy |
3–8 years |
Energy consumed per pallet moved or operating hour |
Compare duty cycles, travel distance, idle time, lifting capacity, charging requirements, and maintenance needs before replacement. |
| 6 |
Optimize Battery Charging |
Use efficient charging schedules, avoid unnecessary idle charging, maintain battery health, and coordinate charging with utility tariffs. |
5–15% of charging electricity |
1–4 years |
Charging efficiency and peak demand in kW |
Provide adequate ventilation where required, balance charging loads, and monitor battery temperature and state of charge. |
| 7 |
Install Variable-Speed Drives |
Apply variable-speed drives to fans, pumps, compressors, and conveyors with varying flow or load requirements. |
10–30% of motor-driven energy |
2–5 years |
Motor load profile and operating speed |
Best results occur on variable-torque applications; verify motor compatibility, controls integration, and harmonic requirements. |
| 8 |
Reduce Compressed-Air Waste |
Repair leaks, lower system pressure where practical, eliminate inappropriate uses, and switch compressors to efficient controls. |
10–30% of compressed-air energy |
1–3 years |
Leak rate, pressure setpoint, and compressor load factor |
Conduct periodic leak surveys and prevent compressed air from being used for cooling, cleaning, or open-ended blow-off when alternatives exist. |
| 9 |
Manage Power Quality and Peak Demand |
Measure power demand, correct phase imbalance, maintain connections, sequence large loads, and reduce avoidable peak-demand charges. |
5–15% of electricity cost |
1–4 years |
Peak demand in kW and power factor |
Use interval metering to identify demand spikes from charging, HVAC startup, refrigeration, conveyors, and other large loads. |
| 10 |
Deploy Energy Monitoring and Controls |
Install submeters and a centralized energy-management system to track lighting, HVAC, charging, refrigeration, and process loads. |
5–15% across monitored loads |
1–4 years |
Energy intensity: kWh per ft², pallet, or shipment |
Set measurable baselines, automated alerts, operating schedules, and monthly performance reviews to sustain savings over time. |
