How Can 7-Eleven Save 30% on Electricity Bills with A 'night Coat'?

How Can 7-Eleven Save 30% on Electricity Bills with A 'night Coat'?

1. Challenge: The "invisible electric tiger" behind 24-hour operation

For the globally renowned convenience store brand 7-Eleven, 24-hour illuminated operation is its core service standard. However, in specific regions such as Japan and North America, the foot traffic at night (from midnight to 6am) is usually less than 5% of that during the day.

The key contradiction lies in:

Although the cashier can turn off the lights, a row of open refrigerators arranged along the wall must operate year-round.

Pain point: On cold winter nights or summer days when the air conditioning is turned on, the cold air inside the freezer continuously pours into the aisle through the open cabinet door interface.

Result: In order to maintain a low temperature of -1 ° C to 4 ° C, the compressor has to operate frequently at high power, resulting in astonishing nighttime electricity expenses and particularly high energy consumption. Customer feedback: "We seem to be cooling the entire street

2. Solution: It's not just about "covering a piece of cloth"

After receiving the customer's request, we did not recommend traditional glass sliding doors (which have high modification costs and affect customer convenience), but instead provided Night Blind (energy-saving cover designed specifically for open refrigerators).

Our product solution:

Customized magnetic frame: No need for punching, perfectly fits the 7-Eleven standard three door vertical freezer.

Material structure: outer reflective aluminum foil+inner food grade PE film

Type selection: screw style, magnetic suction style

Characteristic advantages: Reflective and breathable to prevent water vapor condensation, keeping food fresh

Mold and bacteria proof, durable and beautiful

Easy operation: The salesperson can complete the closing and closing process within 3 seconds before closing the store at night (or before restocking in the early morning).

Implementation process:

We conducted a 4-week A/B test at three selected high energy consuming stores:

Control group: 2 stores continue to use open refrigerators.

Experimental group: Three stores use Night Blind from 22:00 to 07:00 the next day.

3. Data Results: Visible Cost Reduction and Efficiency Enhancement

After a month of monitoring and using smart meters to record the start stop frequency of the refrigeration compressor, we have obtained exciting data:

The baseline for equipment lifespan estimation has been extended by about 2 years to reduce maintenance costs

Key conclusion: By establishing this' cold air barrier 'during off peak hours at night, 7-Eleven not only saved over 30% of electricity costs (measured at 33% -35%), but also significantly extended the lifespan of the compressor.

4. Customer Testimony

At first, we were worried that this would affect customers picking up sandwiches in the early morning, but in reality, the operation was very convenient. When we saw the first month's electricity bill, the data explained everything. This' curtain 'not only blocked the loss of air conditioning, but also held our profit bottom line. We plan to promote this plan to the remaining 50 stores in the area.
