eCube Pilot Results for a Major Retailer

In September 2011, eCube and Green Energy Solutions, Inc conducted a pilot test on various refrigerated and freezer cases in a major retail store. The location chosen was a well established Los Angeles area store. This major retailer is engaging in several energy savings programs from lighting to solar to commercial refrigeration and was very interested in seeing how eCube performed.

Here is a brief summary;

Pilot Goals

1. Confirm Energy savings on Walk in Cooler, Walk in Freezer, Victory Unit, and Cold Case Display

2. Confirm Maintenance Savings on Walk in Cooler, Walk in Freezer, Victory Unit, and Cold Case Display

3. Confirm payback period for rollout

 

Pilot Process

1. Install loggers on designated units

2. Monitor for 3 Days without eCube®

3. Install eCube®, monitor for additional 3 Days

4. Compare results
