Founded in July 1996, Nanjing Suguo, after more than ten years of rapid development, has become a large-scale chain enterprise group integrating wholesale, distribution, logistics, processing and retail.

In 2004, Suguo was identified by the Ministry of Commerce as the 20 large-scale circulation enterprise groups supported by the whole country. Premier Wen Jiabao of the State Council made three important instructions for Suguo and visited the two in person, fully affirming and applauding the “Suguo Supermarket”. Well done."

By the end of 2008, the total number of Suguo outlets had reached 1,800, and the sales volume reached 30 billion yuan. It has entered the top ten chain stores in China for many years, ranking fourth in the Chinese supermarket industry (fast moving consumer goods) and among the top 500 enterprises in China. The 175th strong.

In the past 13 years, Suguo has always adhered to the management tenet of “for the people, convenience, and benefit the people”, constantly exploring and innovating in energy saving and emission reduction, improving the comfort of the shopping environment, and creating intelligent energy saving in its 24-hour convenience store. Lighting and electrical appliances contribute to creating a community that saves energy, is green, and is sustainable.

Tridonic Lighting Electronics (Shanghai) Co., Ltd. provided the industry-leading intelligent lighting digital appliances and products for the project, and cooperated with the high-efficiency lighting T5 lamps to create an energy-saving, comfortable and safe shopping environment. A new trend in the development of energy-saving and intelligent convenience stores in the 21st century.

Save 1 kWh = achieve 100 yuan sales

What does it mean to save 1 kWh in the supermarket industry? "Save 1 kWh = achieve 100 yuan sales." According to industry data, the average net profit margin of large supermarkets is currently only about 1%, saving 1 kWh of electricity, which is equivalent to achieving a profit of 100 yuan in sales.

At present, there are more than 1,600 chain stores in Suguo Supermarket, including shopping malls, standard supermarkets, community stores, convenience stores and other formats. The largest area is 12,000 square meters, and the smallest area is about 50 square meters. Lighting consumes a lot of power. At present, there are nearly 300 convenience store in Suguo, and 20-30 new stores are opened every year. The lighting energy-saving retrofit solution of this paper is tailor-made for 24-hour convenience and 24-hour standard supermarket. It has the characteristics of strong pertinence, remarkable energy saving and short payback period. It can save lighting energy consumption to the greatest extent and indirectly achieve sales profit growth.

Save 1 kWh = reduce 1.5 lbs of carbon emissions

According to professional statistics, the amount of carbon dioxide emitted per kilowatt-hour of electricity production is about 0.75 kilograms. According to professional statistics, lighting accounts for about 25% of the energy consumption in supermarkets, so the savings in electricity consumption can be greatly reduced. Carbon dioxide emissions. In fact, in most cases, many areas in the supermarket do not need to open or open the lights to the brightest. Excessive lighting not only causes light pollution but also causes energy waste. In today's energy shortage and the country's vigorous promotion of energy conservation, the use of smart lighting digital appliances and products can maximize the saving of lighting energy, so the successful application of smart lighting digital appliances and products in supermarkets has very practical and important significance.

Lighting before renovation = waste + uncomfortable

At present, the general use of lighting fixtures in convenience stores and supermarkets in 24 hours can be roughly divided into three time periods.

1, during the day (8:00-17:00 customers are relatively scattered)

2, at night (18:00-21:00 customers are relatively concentrated)

3, late at night (22:00-7:00 customers are relatively rare)

There are two general states of turning on the lights.

1. The lights are fully turned on in the three time periods.

2. The lights are fully open during the day and night, and halfway through at night.

Problem

1. When fully open, it is obvious that at least half of the electricity bill is wasted, and excessive lighting can cause glare and form light pollution.

2. When the half is opened, the illumination inside the supermarket is very uneven. The illuminance difference between the highest illuminance area and the lowest illuminance area is 310 LUX; the illuminance difference of the cashier area is 137 LUX; the maximum illuminance value of the shelf area is also 112 LUX, the uniformity is affected, and the customer feels visually uncomfortable, thus greatly Reduced the comfort of the entire convenience store.

Retrofit lighting = saving + comfort

Through the above analysis, it can be seen that the 24-hour convenience store, no matter the number of customers, the lighting in the store must be 100% light, although it can be energy-saving by closing the control mode of some lighting fixtures through the strong electric circuit. However, the uniformity of lighting in the store has been affected, and the customer feels uncomfortable visually. This method relies on human control and cannot save energy from management.

We use the Tridonic Digital Dimming Ballast (ECO) + Infrared Sensor to keep the lighting fixtures low in the area where there are no customers, but when the customer approaches the shopping area, the lights are fully turned on for customers to shop. In the window area, we use DSI-A/D + SMART-LS II to control the brightness of the light with daylight compensation. At night, the window light is completely open, which is very eye-catching to attract passers-by to go shopping, and work in the cashier area. The personnel can manually adjust the brightness of the area according to the passenger flow. Such a control method can meet the illumination requirements of the customer when shopping, and can save energy in real time to reduce the operating cost for the enterprise.
