How Loeb Brightened Up the Largest Retailer in the World

circuits Created with Sketch.

Executive Summary

Walmart provides their customers with “everyday low prices,” and they strive to do this sustainably, with a key focus on energy savings. As part of their green initiative, Walmart needed to upgrade from fluorescent to LED lighting throughout their large, multi-generational fleet of stores. This called for a customized plan built with and entrusted to Loeb Electric including audits, technology enablement, product development, inventory logistics, and project management.

The Challenges

With more than 4,700 stores across the U.S. in varying layouts, and with an average of approximately 160,000 square feet per store, Walmart’s green initiative needed to be executed at a massive scale. They needed a national partner that could not only handle such a complex job—including design, installation, audits, rebate capture, and warranty management—but who could tailor a solution to their specific needs; they needed a partner they could trust.

The Solution

With a relationship spanning more than a decade and covering everything from material supply to project management to reactive maintenance service, Walmart chose Loeb Electric to customize, manage, and execute a solution built specifically to achieve their massive green initiative goals.
