CASE STUDY — DISTRIBUTION & LOGISTICS

280,000 Sq Ft Warehouse
Retrofitted in 3 Weeks

A regional logistics operator was burning through electricity and maintenance hours on aging metal halide and fluorescent fixtures across a 24/7 distribution center. Echelon delivered a turnkey LED retrofit in three weeks, cut lighting costs 63% from month one, and did the entire install on nights and weekends without losing a single shift.

PROJECT PROFILE

The Facility

VERTICAL
Logistics & Distribution

Regional third-party logistics operator running pick, pack, and ship operations on a 24/7 schedule. Inbound and outbound truck doors across both long sides of the building.

FOOTPRINT
280,000 Sq Ft

Single-story facility with high-bay racking aisles, dock zones, pack-out areas, and back-office workspace. Ceiling heights between 28 and 32 feet across the warehouse floor.

EXISTING SYSTEM
Mixed Legacy Stock

Aging 400W metal halide high-bays on the warehouse floor, T8 fluorescent troffers in office and pack-out zones, and HID wall packs at dock doors and exterior perimeter.

THE CHALLENGE

What the Operator Was Up Against

The facility was carrying three problems at once, each making the others worse:

  • Rising operating costs. Lighting alone accounted for a quarter of the facility's electric bill, with consumption climbing year over year as ballasts degraded and lamps drew more current.
  • Maintenance burden at altitude. Lamp replacements on 30-ft ceilings required scissor lifts, work-stoppage zones, and outside contractors. Each fixture failure cost more in labor than the lamp itself.
  • Supply pressure on fluorescent stock. With T8 and HID lamps facing phase-out and rising distributor prices, leadership couldn't keep deferring a system upgrade.
  • No room for downtime. The site runs continuous shifts. Any installation strategy that required halting operations was a non-starter, regardless of savings.

The procurement team had received two prior LED retrofit bids that quoted occupied-hours work with rolling shutdowns across zones. Both were rejected. Echelon was brought in to design around the operating reality, not the other way around.

THE SOLUTION

Design Decisions That Drove the Outcome

Three engineering choices made the 63% reduction possible — without them the project would have looked like a routine like-for-like swap.

DECISION 01
Photometric Redesign in AGi32

Rather than swap 400W metal halides one-for-one, Echelon's engineers ran a full photometric layout in AGi32. The result: fewer fixtures than the existing layout, properly aimed to deliver uniform foot-candle levels across racking aisles instead of pooling light in the wrong spots.

DECISION 02
DLC-Listed High-Bays + Integral Controls

DLC-listed LED high-bay fixtures with integral occupancy sensors and dimming. Aisles in low-traffic zones drop to a baseline output and ramp to full when forklifts approach — capturing additional savings on top of the LED swap itself.

DECISION 03
Phased Off-Shift Execution

The install was sequenced section-by-section during off-peak shift windows. Crews worked nights and weekends, completed each zone end-to-end before moving to the next, and never touched an active operational area during productive hours.

EXECUTION

Three Weeks, Zero Downtime

WEEK 0
Audit & Design

On-site fixture inventory, energy baseline measurement, photometric design, rebate pre-approval submitted to the utility under the customer's name. ROI report delivered before any work order signed.

WEEK 1
Dock & Pack-Out Zones

Started in the dock and pack-out zones with the highest fixture density and lowest disruption risk. Crews worked overnight shifts. As-built drawings updated daily and shared with the operations team each morning.

WEEK 2
Warehouse Floor

Main warehouse high-bay replacement progressed aisle-by-aisle. Controls programming validated zone-by-zone. Site walks with the operations manager at the end of each shift to confirm production wasn't affected.

WEEK 3
Office, Exterior, Commissioning

Final zones (office, exterior wall packs, dock doors) completed. Full commissioning, controls programming verified, rebate documentation submitted. 30-day metered savings report scheduled before final invoice.

RESULTS

What the Numbers Looked Like

The first month's utility bill showed the project paying for itself faster than the original ROI projection. Three results stood out:

  • 63% reduction in lighting costs from month one. Measured against the prior-year baseline for the same billing period. Verified with metered submeter data, not estimated from connected load.
  • Utility rebate captured covered a significant portion of the project cost. Pre-approval and final paperwork handled by Echelon under the customer's name; the rebate check was issued to the customer directly.
  • Lighting maintenance line item effectively eliminated. Lamp replacement schedule that previously consumed dedicated maintenance hours and outside lift rentals dropped to near zero. DLC-listed fixtures carry 5-year warranty plus 50,000+ hour rated life.

Beyond the metered numbers, the operations team flagged two qualitative wins: brighter, more uniform light levels in the racking aisles improved order-pick accuracy, and exterior dock area improvements reduced after-dark slip-and-fall risk during winter shift changes.
